Tags Share this article 2/11/24 Published Modern organizations face a wide and constantly changing range of network security threats, and security leaders must constantly update their security posture against them. As threat actors change their tactics, techniques, and procedures, exploit new vulnerabilities , and deploy new technologies to support their activities — it’s up to security teams to respond by equipping themselves with solutions that address the latest threats. The arms race between cybersecurity professionals and cybercriminals is ongoing. During the COVID-19 pandemic, high-profile ransomware attacks took the industry by storm. When enterprise security teams responded by implementing secure backup functionality and endpoint detection and response, cybercriminals shifted towards double extortion attacks. The cybercrime industry constantly invests in new capabilities to help hackers breach computer networks and gain access to sensitive data. Security professionals must familiarize themselves with the latest network security threats and deploy modern solutions that address them. What are the Biggest Network Security Threats? 1. Malware-based Cyberattacks Malware deserves a category of its own because so many high-profile attacks rely on malicious software to work. These include everything from the Colonial Pipeline Ransomware attack to historical events like Stuxnet . Broadly speaking, cyberattacks that rely on launching malicious software on computer systems are part of this category. There are many different types of malware-based cyberattacks, and they vary widely in scope and capability. Some examples include: Viruses. Malware that replicates itself by inserting its own code into other applications are called viruses. They can spread across devices and networks very quickly. Ransomware. This type of malware focuses on finding and encrypting critical data on the victim’s network and then demanding payment for the decryption key. Cybercriminals typically demand payment in the form of cryptocurrency, and have developed a sophisticated industrial ecosystem for conducting ransomware attacks. Spyware. This category includes malware variants designed to gather information on victims and send it to a third party without your consent. Sometimes cybercriminals do this as part of a more elaborate cyberattack. Other times it’s part of a corporate espionage plan. Some spyware variants collect sensitive information that cybercriminals value highly. Trojans. These are malicious applications disguised as legitimate applications. Hackers may hide malicious code inside legitimate software in order to trick users into becoming victims of the attack. Trojans are commonly hidden as an email attachment or free-to-download file that launches its malicious payload after being opened in the victim’s environment. Fileless Malware. This type of malware leverages legitimate tools native to the IT environment to launch an attack. This technique is also called “living off the land” because hackers can exploit applications and operating systems from inside, without having to download additional payloads and get them past firewalls. 2. Network-Based Attacks These are attacks that try to impact network assets or functionality, often through technical exploitations. Network-based attacks typically start at the edge of the network, where it sends and receives traffic to the public internet. Distributed Denial-of-Service (DDoS) Attacks. These attacks overwhelm network resources, leading to downtime and service unavailability, and in some cases, data loss . To launch DDoS attacks, cybercriminals must gain control over a large number of compromised devices and turn them into bots. Once thousands (or millions) of bots using unique IP addresses request server resources, the server breaks down and stops functioning. Man-in-the-Middle (MitM) Attacks: These attacks let cybercriminals eavesdrop on communications between two parties. In some cases, they can also alter the communications between both parties, allowing them to plan and execute more complex attacks. Many different types of man-in-the-middle attacks exist, including IP spoofing, DNS spoofing, SSL stripping, and others. 3. Social Engineering and Phishing These attacks are not necessarily technical exploits. They focus more on abusing the trust that human beings have in one another. Usually, they involve the attacker impersonating someone in order to convince the victim to give up sensitive data or grant access to a secure asset. Phishing Attacks. This is when hackers create fake messages telling victims to take some kind of action beneficial to the attacker. These deceptive messages can result in the theft of login credentials, credit card information, or more. Most major institutions are regularly impersonated by hackers running phishing scams, like the IRS . Social Engineering Attacks. These attacks use psychological manipulation to trick victims into divulging confidential information. A common example might be a hacker contacting a company posing as a third-party technology vendor, asking for access to a secure system, or impersonating the company CEO and demanding an employee pay a fictitious invoice. 4. Insider Threats and Unauthorized Access These network security threats are particularly dangerous because they are very difficult to catch. Most traditional security tools are not configured to detect malicious insiders, who generally have permission to access sensitive data and assets. Insider Threats. Employees, associates, and partners with access to sensitive data may represent severe security risks. If an authorized user decides to steal data and sell it to a hacker or competitor, you may not be able to detect their attack using traditional security tools. That’s what makes insider threats so dangerous, because they are often undetectable. Unauthorized Access. This includes a broad range of methods used to gain illegal access to networks or systems. The goal is usually to steal data or alter it in some way. Attackers may use credential-stuffing attacks to access sensitive networks, or they can try brute force methods that involve automatically testing millions of username and password combinations until they get the right one. This often works because people reuse passwords that are easy to remember. Solutions to Network Security Threats Each of the security threats listed above comes with a unique set of risks, and impacts organizations in a unique way. There is no one-size-fits-all solution to navigating these risks. Every organization has to develop a cybersecurity policy that meets its specific needs. However, the most secure organizations usually share the following characteristics. Fundamental Security Measures Well-configured Firewalls. Firewalls control incoming and outgoing network traffic based on security rules. These rules can deny unauthorized traffic attempting to connect with sensitive network assets and block sensitive information from traveling outside the network. In each case, robust configuration is key to making the most of your firewall deployment . Choosing a firewall security solution like AlgoSec can dramatically improve your defenses against complex network threats. Anti-malware and Antivirus Software. These solutions detect and remove malicious software throughout the network. They run continuously, adapting their automated scans to include the latest threat detection signatures so they can block malicious activity before it leads to business disruption. Since these tools typically rely on threat signatures, they cannot catch zero-day attacks that leverage unknown vulnerabilities. Advanced Protection Tools Intrusion Prevention Systems. These security tools monitor network traffic for behavior that suggests unauthorized activity. When they find evidence of cyberattacks and security breaches, they launch automated responses that block malicious activity and remove unauthorized users from the network. Network Segmentation. This is the process of dividing networks into smaller segments to control access and reduce the attack surface. Highly segmented networks are harder to compromise because hackers have to repeatedly pass authentication checks to move from one network zone to another. This increases the chance that they fail, or generate activity unusual enough to trigger an alert. Security and Information Event Management (SIEM) platforms. These solutions give security analysts complete visibility into network and application activity across the IT environment. They capture and analyze log data from firewalls, endpoint devices, and other assets and correlate them together so that security teams can quickly detect and respond to unauthorized activity, especially insider threats. Endpoint Detection and Response (EDR). These solutions provide real-time visibility into the activities of endpoint devices like laptops, desktops, and mobile phones. They monitor these devices for threat indicators and automatically respond to identified threats before they can reach the rest of the network. More advanced Extended Detection and Response (XDR) solutions draw additional context and data from third party security tools and provide in-depth automation . Authentication and Access Control Multi-Factor Authentication (MFA). This technology enhances security by requiring users to submit multiple forms of verification before accessing sensitive data. This makes it useful against phishing attacks, social engineering, and insider threats, because hackers need more than just a password to gain entry to secure networks. MFA also plays an important role in Zero Trust architecture. Strong Passwords and Access Policies. There is no replacement for strong password policies and securely controlling user access to sensitive data. Security teams should pay close attention to password policy compliance, making sure employees do not reuse passwords across accounts and avoid simple memory hacks like adding sequential numbers to existing passwords. Preventing Social Engineering and Phishing While SIEM platforms, MFA policies and strong passwords go a long way towards preventing social engineering and phishing attacks, there are a few additional security measures worth taking to reduce these risks: Security Awareness Training. Leverage a corporate training LMS to educate employees about phishing and social engineering tactics. Phishing simulation exercises can help teach employees how to distinguish phishing messages from legitimate ones, and pinpoint the users at highest risk of falling for a phishing scam. Email Filtering and Verification: Email security tools can identify and block phishing emails before they arrive in the inbox. They often rely on scanning the reputation of servers that send incoming emails, and can detect discrepancies in email metadata that suggest malicious intent. Even if these solutions generally can’t keep 100% of malicious emails out of the inbox, they significantly reduce email-related threat risks. Dealing with DDoS and MitM Attacks These technical exploits can lead to significant business disruption, especially when undertaken by large-scale threat actors with access to significant resources. Your firewall configuration and VPN policies will make the biggest difference here: DDoS Prevention Systems. Protect against distributed denial of service attacks by implementing third-party DDoS prevention solutions, deploying advanced firewall configurations, and using load balancers. Some next generation firewalls (NGFWs) can increase protection against DDoS attacks by acting as a handshake proxy and dropping connection requests that do not complete the TCP handshake process. VPNs and Encryption: VPNs provide secure communication channels that prevent MitM attacks and data eavesdropping. Encrypted traffic can only be intercepted by attackers who go through the extra step of obtaining the appropriate decryption key. This makes it much less likely they focus on your organization instead of less secure ones that are easier to target. Addressing Insider Threats Insider threats are a complex security issue that require deep, multi-layered solutions to address. This is especially true when malicious insiders are actually employees with legitimate user credentials and privileges. Behavioral Auditing and Monitoring: Regular assessments and monitoring of user activities and network traffic are vital for detecting insider threats . Security teams need to look beyond traditional security deployments and gain insight into user behaviors in order to catch authorized users doing suspicious things like escalating their privileges or accessing sensitive data they do not normally access. Zero Trust Security Model. Assume no user or device is trustworthy until verified. Multiple layers of verification between highly segmented networks — with multi-factor authentication steps at each layer — can make it much harder for insider threats to steal data and conduct cyberattacks. Implementing a Robust Security Strategy Directly addressing known threats should be just one part of your cybersecurity strategy. To fully protect your network and assets from unknown risks, you must also implement a strong security posture that can address risks associated with new and emerging cyber threats. Continual Assessment and Improvement The security threat landscape is constantly changing, and your security posture must adapt and change in response. It’s not always easy to determine exactly how your security posture should change, which is why forward-thinking security leaders periodically invest in vulnerability assessments designed to identify security vulnerabilities that may have been overlooked. Once you have a list of security weaknesses you need to address, you can begin the process of proactively addressing them by configuring your security tech stack and developing new incident response playbooks. These playbooks will help you establish a coordinated, standardized response to security incidents and data breaches before they occur. Integration of Security Tools Coordinating incident response plans isn’t easy when every tool in your tech stack has its own user interface and access control permissions. You may need to integrate your security tools into a single platform that allows security teams to address issues across your entire network from a single point of reference. This will help you isolate and address security issues on IoT devices and mobile devices without having to dedicate a particular team member exclusively to that responsibility. If a cyberattack that targets mobile apps occurs, your incident response plan won’t be limited by the bottleneck of having a single person with sufficient access to address it. Similarly, highly integrated security tools that leverage machine learning and automation can enhance the scalability of incident response and speed up incident response processes significantly. Certain incident response playbooks can be automated entirely, providing near-real-time protection against sophisticated threats and freeing your team to focus on higher-impact strategic initiatives. Developing and Enforcing Security Policies Developing and enforcing security policies is one of the high-impact strategic tasks your security team should dedicate a great deal of time and effort towards. Since the cybersecurity threat landscape is constantly changing, you must commit to adapting your policies in response to new and emerging threats quickly. That means developing a security policy framework that covers all aspects of network and data security. Similarly, you can pursue compliance with regulatory standards that ensure predictable outcomes from security incidents. Achieving compliance with standards like NIST, CMMC, PCI-DSS, and HIPPA can help you earn customers’ trust and open up new business opportunities.

Vitae donec tincidunt elementum quam laoreet duis sit enim. Duis mattis velit sit leo diam. Tags Share this article 12/20/23 Published 14 Step Checklist for a Flawless Network Security Audit If security policies aren’t periodically updated to meet modern threat demands, organizations risk introducing vulnerabilities into their IT security posture. Comprehensive audit reports help security leaders gain in-depth visibility into their organization’s cybersecurity strategy and assess the resilience of its network infrastructure . Network Security Audit Checklist: What Does Your IT Security Audit Need to Cover? Cybersecurity audits demand an extensive overview of the organization’s security posture and risk profile. It requires gathering and analyzing network data to identify security vulnerabilities, monitor access controls, and assess potential threats. It also includes an overview of operational security practices, penetration testing results, and incident response playbooks . Ultimately, comprehensive risk assessment data should guide the organization towards improving its security measures and preventing hackers from breaching critical data and assets. A complete network security audit should include provide in-depth visibility into the following: Security controls and their implementation. The availability of network devices and access points. High-impact security risks and their potential consequences. The effectiveness of information security management processes. Performance data on security systems and network assets like firewalls. What Do Network Security Audits Help You Achieve? Conducting in-depth security audits helps security leaders identify data breach risks and develop plans for managing those risks. Audit results play an incredibly important role in preventative risk management and in the remediation of cyberattacks. Organizations that regularly conduct these kinds of assessments are better equipped to address the security weaknesses that might arise when onboarding new users, adding new endpoints to the network, or installing new apps. Network audits and security assessments can also help you achieve other important goals as well, such as: Identifying network performance issues and addressing them to improve overall performance. Unlocking opportunities to leverage network assets and mobile devices more efficiently. Demonstrating compliance with regulatory frameworks like the NIST Cybersecurity Framework 1.1 , ISO 27001 and 27002 , and SOC 2 Type 2 . Present security performance information to core stakeholders to demonstrate the value of security policies and controls. Update system security processes to address new vulnerabilities and potential threats. Recommended Read: 20 Best Network Security Solutions + FAQs How to Perform a Network Security Audit The network audit process involves collecting data, analyzing it to identify potential threats, and using it to compile a formal audit report. Depending on the size and complexity of the organization, this audit may be performed by an individual network analyst, a third-party IT security audit specialist, or an entire team of internal security professionals. These are the steps that make up a typical network audit: 1. Plan for the audit and inform everyone involved The audit process will involve many different types of technical tasks. The specific steps you take will change depending on the complexity of your network and the specialist talent required to assess data security in different IT contexts. You will need to verify authentication protocols, operating system security, password policies, and more. It’s rare for an individual security auditor to have all the technical skills necessary to do this on every app, device, and platform an organization uses. In most cases, you’ll need to work with other employees, third-party service providers, and other stakeholders to obtain the data you need. 2. Document all procedures and processes associated with the audit Recording every process that takes place during the audit is crucial. When preparing your final report, you may want to go back and verify some of the processes that took place to ensure the fidelity and accuracy of your data. If methodological errors creep into your data, they can skew your final report’s findings and end up damaging your ability to secure sensitive data correctly. Documentation is especially important in network security audits because you are looking for systematic flaws in the way user accounts, network assets, and security systems interact with one another. These flaws may not reveal themselves without clear documentation. 3. Review standard operating procedures and how they are managed Protecting sensitive information and critical network assets from security threats takes more than sophisticated technology. It also requires strict adherence to security policies and best practices from human users. Security audits should verify that employees and third-party providers are observing security policies in their operating procedures, and provide evidence attesting to that fact. Reviewing the organization’s procedure management system should provide key insight into whether users are following procedures or not. If they are not, there is a high risk of shadow IT processes leading to phishing attacks and security breaches. This should be reported so that the security team can find ways to remediate these threats. 4. Assess the training logs and operations Human error is behind eight out of ten cyberattacks . All customer-facing employees should be trained to detect phishing and social engineering attacks, and internal staff should know how to prevent malware from infecting the network. Every employee should understand how their role contributes to the security profile of the organization as a whole. Verifying authentication processes, permissions, and password policy is also part of employee training. Every user account should be protected by a consistent policy that follows the latest guidelines for beating brute force and dictionary-based credential attacks. Data encryption policies should keep sensitive login credentials secure even if hackers successfully compromise network assets. 5. Confirm the security patches for network software are up-to-date Start by creating a list of every software application used on the network. This can be a long, time-consuming manual process, but there are automated vulnerability scanning solutions that can help you automate this step. You will have to investigate each item on the list and determine whether new security patches are installed in a reasonably tight time frame. Keep in mind that cybercriminals often exploit security patch releases by scanning for organizations that delay installing new patches. Patch release changelogs essentially broadcast known vulnerabilities directly to hackers, so exploiting late patch installations is a trivial task. 6. Confirm the penetration testing policy and process is sufficient Penetration testing is one of the best ways to identify vulnerabilities on a network. If your organization has invested in pentesting initiatives, you will need to review and confirm its policies as part of the network security audit process. If you haven’t yet invested in pentesting, you may wish to outline a potential path for incorporating it into your security processes here. You may wish to verify the size and scope of your pentesting processes at this point. Assess some of the vulnerabilities you have uncovered and determine whether the organization is investing the appropriate resources into pentesting, or whether other security initiatives should take precedence. 7. Identify gaps and misconfigurations in your firewall policies Your organization’s firewalls play an important role managing traffic between network assets. Firewall rules should not be static. They must be continuously updated to meet the needs of the organization as it changes and grows. These devices can enforce bring your own device (BYOD) mobile policies, prevent distributed denial of service (DDoS) attacks, and contribute to proper network segmentation. Manually configuring firewall policies can be costly and time-consuming. Consider using an automated change management platform like AlgoSec Firewall Analyzer to rapidly identify potential vulnerabilities in your firewall rules. Document any changes you make and include those updates in your report. 8. Ensure all sensitive and confidential data is stored securely Every organization has to store some form of sensitive or confidential data. A major goal of network security audits is making sure this data is kept separate from non-sensitive data and protected by a higher standard of security. This data includes individuals’ names, addresses, phone numbers, financial information, and government ID data. Access to sensitive data should be only allowed when critical for business purposes, and every action involving sensitive data should generate comprehensive logs. The data itself should be encrypted so that even if attackers successfully breach the database, they won’t be able to use the data itself. It may also be worth considering an enterprise data backup solution to provide a failsafe in the event of a disaster. 9. Encrypt the hard disks on any company laptops Portable devices like laptops should not generally hold sensitive data. However, many employees can’t work without processing some amount of sensitive data and storing it on the local hard drive. This is usually less than critical data, but it can still contribute to a cyberattack if it falls into the wrong hands. Encrypting laptop hard disks can help prevent that from happening. If all the data on the device is encrypted, then the organization can avoid triggering a crisis-level security incident every time an employee misplaces or loses a company device. 10. Check the security of your wireless networks Wireless network security is vital for preventing hackers from conducting phishing attacks against employees and on-premises customers. If your organization’s Wi-Fi network is not secured, hackers can spoof the network and trick users into giving up vital information without their knowledge. All modern Wi-Fi equipment supports multiple security protocols. Avoid WEP and WPA – these are old protocols with well-known security vulnerabilities – and make sure your networks are using WPA2. If the organization has equipment that does not support WPA2, you must upgrade the equipment. 11. Scan for and identify any unauthorized access points Your network may have access points that were never set up or approved by the organization. Cybercriminals can use these unauthorized access points to steal data without triggering exfiltration alerts. Additional Wi-Fi frequencies are a common culprit here – your private Wi-Fi network may be configured to use the 2.4 GHz band even though you have equipment that supports 5 GHz frequencies. If someone sets up an access point on the 5 GHz frequency, you can easily overlook it. Data breaches can occur over a wide variety of similar media. USB and Bluetooth-enabled devices have introduced malware into corporate networks in the past. Your security audit should cover as many of these communication channels as possible. 12. Review the event log monitoring process The best way to verify security events is by analyzing the logs generated by network assets as they respond to user interactions. These logs can tell you who accessed sensitive data and report where and when that access took place. Security analysts can connect log data across applications to contextualize security incidents and understand how they took place. The problem is that even a small organization with a simple network can generate an enormous volume of log data every day. Your security audit should investigate the event log monitoring process and look for opportunities to streamline it. You may consider implementing a security information and event management (SIEM) platform or improving your existing one. 13. Compile a comprehensive report Once you’ve gathered all the relevant data and included your insight into the organization’s security posture, you are ready to create your audit report. This report should compile all of your findings into a single well-organized document, with evidence supporting the claims you make and clear recommendations for improving operational security moving forward. Consider creating customized data visualizations to showcase how key performance metrics change over time. The way you choose to communicate data can have a major impact on the way it is received, potentially convincing key stakeholders to implement the changes you suggest. 14. Send the final report to appropriate stakeholders and other key parties. Once you’ve finished your network security audit, you are ready to send it to your organization’s leaders and any other stakeholders who have an interest in your findings. Be prepared to explain your recommendations and justify the methods you used to collect and analyze the organization’s security data. The more confident you are in the accuracy of your findings, the better-equipped you’ll be to present them if called upon.

Firewall Change Management Change automation: A step-by-step guide to network security policy change management Avivi Siman Tov 2 min read Avivi Siman Tov 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 10/21/21 Published Avivi Siman-Tov, Director of Product Management at AlgoSec, discusses the benefits of network automation and takes us through a step-by-step process to standardize change management In today’s fast-paced, data-driven environment, the only constant that businesses can bank on is change. For organizations to function and compete in the modern digital landscape, they need their data to be able to move freely and unobstructed through every branch of their business, unimpeded by security issues that require constant manual attention. The network is arguably the beating heart of an organization but keeping it ticking requires more maintenance than it once did, owing to constantly changing risk profiles and circumstances. That’s why a greater number of businesses are turning to change automation to bridge the gap between network alerts and the action that needs to be taken. Barriers to automation According to Gartner , organizations that can automate more than 70% of their network changes can reduce the number of outages by at least 50% and deliver services up to 50% faster. That’s because a lot of legacy solutions tend to take a reactive rather than proactive approach to dealing with security. There are multiple controls in place that simply don’t talk to each other. While most businesses get alerts from SIEM solutions and vulnerability scanners, responding to them turns into a full-time job, distracting your team from other important work they could be doing. Most organizations know that manual policy changes impact their productivity, but they’re afraid to take the leap to automation because of an ill-placed perception around security. Production environments in all organizations are maintained by different teams — for example, DevOps, maintenance, cloud security, IT, and more. Not all of these teams are educated to the same level in security matters, and some see it as a constraint that slows their work. This can lead to conflict between teams, which means that automation is not always welcome. Despite some resistance to change, enterprise-wide change automation makes it possible to transform network security policies without needing to reinvent the wheel or replace existing business processes. Automation and actionable intelligence are proven to enhance security and business agility without the stress often associated with misconfigurations caused by manual, ad-hoc processes. A typical network change workflow By elevating firewall change management from a manual, arduous task to a fully automated, zero-touch process, networks can become more agile and organizations far more adaptive. There are several steps that organizations need to take towards complete network security automation, from a simple change request through to implementation and validation. Let’s take a look at the most common steps in establishing automation for a simple change request. Step 1 – Request a network change Every change begins with a request. At this stage, you need to clarify who is asking for the amendment and why because sometimes the request is unnecessary or covered by an existing ruleset. Step 2 – Find relevant security devices Once this request is translated, the change automation platform will handle the request and implement the changes to hybrid networks. The administrator will be able to see which firewall and routing devices are involved and what impact the change will have. Step 3 – Plan change The change automation platform understands how to deal with different vendor-specific settings and how to implement the requests in a way that avoids creating any duplicates. Step 4 – Risk check The administrator will get a ‘ what if’ analysis, which checks the change for any risks. In this phase, the decision as to whether to allow the change and expose the network to the risk mentioned is in the hands of the network admin or security manager, depending on who is handling this phase. Step 5 – Push change to device Once planned changes are approved, the ‘magic’ happens. The change automation platform implements and pushes the changes to the desired devices automatically, either through APIs or directly to the device (CLI). This is a fully automated action that can be conducted on multiple devices, whether cloud-based or on-premises. The push can be done in a scheduled manner, in your maintenance window, or on-demand. Step 6 – Validate change At the end of each request, the solution will check that the request was successfully implemented across all devices. The solution also provides ongoing audits of the whole process, enabling easy checking of each stage. Step 7 – Documentation and logging Network security automation platforms can provide you with a full, automated audit trail. Documentation happens on the go, saving IT and security teams time and accelerating tedious network compliance management tasks. Put your trust in network automation While change management is complex stuff, the decision for your business is simple. It’s like the engine of an expensive car. Would you drive at high speeds if you didn’t have your brakes tested or a steering wheel to keep your course straight? Hopefully, the answer is no.

Cloud Network Security Enhancing container security: A comprehensive overview and solution Nitin Rajput 2 min read Nitin Rajput 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. cloudsecurity, cnapp, networksecurity Tags Share this article 1/23/24 Published In the rapidly evolving landscape of technology, containers have become a cornerstone for deploying and managing applications efficiently. However, with the increasing reliance on containers, understanding their intricacies and addressing security concerns has become paramount. In this blog, we will delve into the fundamental concept of containers and explore the crucial security challenges they pose. Additionally, we will introduce a cutting-edge solution from our technology partner, Prevasio, that empowers organizations to fortify their containerized environments. Understanding containers At its core, a container is a standardized software package that seamlessly bundles and isolates applications for deployment. By encapsulating an application’s code and dependencies, containers ensure consistent performance across diverse computing environments. Notably, containers share access to an operating system (OS) kernel without the need for traditional virtual machines (VMs), making them an ideal choice for running microservices or large-scale applications. Security concerns in containers Container security encompasses a spectrum of risks, ranging from misconfigured privileges to malware infiltration in container images. Key concerns include using vulnerable container images, lack of visibility into container overlay networks, and the potential spread of malware between containers and operating systems. Recognizing these challenges is the first step towards building a robust security strategy for containerized environments.

Tags Share this article 8/28/23 Published Before your organization can move business applications to the cloud, it must deploy network security solutions that can reliably block cybercrime and malware. Firewalls are essential cybersecurity tools that protect network traffic against threat actors. There are many different types of firewalls available, but put the same basic principles in action. Before finding out which types of firewalls offer the best security performance for your cloud implementation, it’s important to cover how firewalls work and what characteristics set them apart. How firewalls work: Different types of firewalls explained Firewalls are best explained through analogy. Think of firewalls as 24/7 security guards with deep knowledge of millions of criminals. Whenever the security guard sees a criminal approaching an access point, they block access and turn the criminal away. This kind of access control is accomplished in a few different ways. Some firewalls inspect packets for suspicious characteristics. Others use stateful inspection to identify malicious traffic. Some incorporate contextual awareness to tell the difference between harmless traffic and cyberattacks . Here are some of the major types of firewalls and how they work: Packet filtering firewalls inspect data traveling through inline junction points like routers and switches. They don’t route data packets themselves, but compare them to a list of firewall rules. For example, they may filter packets that are traveling to untrusted IP addresses and drop them. Circuit-level gateways monitor TCP handshake data and other protocol messages for signs of unauthorized access. These firewalls don’t inspect individual packets or application layer monitoring, though. Proxy firewalls apply application layer filtering that filters data according to a wide range of characteristics. This category includes web application firewalls, which are a type of reverse proxy firewall – they protect the server from malicious traffic by filtering clients before they reach the server. Stateful inspection firewalls examine and compare multiple packets to find out if they are part of an established network session. This offers a high degree of control over incoming and outgoing traffic while providing comprehensive logs on network connections. Next-generation firewalls combine packet inspection, stateful inspection, antivirus, and additional technologies to protect organizations against unknown threats and vulnerabilities. These firewalls are expensive and have high bandwidth requirements, but they also offer a high level of protection. All of these firewalls exist in different forms. Traditional hardware firewalls are physical devices that sit between network devices and the internet. Network-based firewalls are software-defined apps designed to do the same thing. Hardware, software, or cloud? firewall deployment methods compared Organizations have multiple options when deciding to host firewalls on their private networks. The market offers a vast number of security devices and firewall providers, ranging from Cisco hardware to software solutions like Microsoft’s Windows firewall. Large enterprises use a combination of firewall solutions to adopt a multi-layered security posture. This allows them to achieve network scalability and segmentation while offering different levels of protection to data centers, individual devices, and user endpoints. As firewall technology becomes more accessible, smaller organizations are following suit. Here are some of the delivery formats that firewall solutions commonly come in: Network-based Firewalls are self-contained hardware appliances. They typically run custom operating systems using Linux distributions designed for secure computer networking. They can be challenging to configure and deploy, but are appropriate for a wide range of use cases. Host-based Firewalls run as software on a server or other device. You can run host-based firewalls on individual computers, or at the host level of a cloud environment. The firewalls offer granular control over security rules and individual hosts, but consume resources in the process. Cloud Hosted Firewalls are provided by third-party security partners as a service. These firewalls may be entirely managed by a third-party partner, making them ideal for small organizations that can’t afford building their own security infrastructure from the ground up. How to select an optimal firewall solution for your organization Every organization has a unique security risk profile. Finding the right firewall deployment for your organization requires in-depth knowledge of your network’s security vulnerabilities and potential for long-term growth. Some of the issues you have to consider include: Identifying technical objectives for individual firewalls. There are no one-size-fits-all firewall solutions. One solution may match a particular use case that another does not. Both stateless packet inspection firewalls and sophisticated next-generation solutions operate at different levels of the OSI model, which means each device should serve a well-defined purpose. Selecting firewall solutions that match your team’s expertise. Consider your IT team’s technical qualifications. If configuring a sophisticated next-generation firewall requires adding talent with specialized certifications to your team, the cost of that deployment will rise considerably. Deploying firewalls in ways that improve security performance while reducing waste. Optimal firewall architecture requires effective network segmentation and good security policies. Deploying a secure local area network (LAN) and using virtual private networks (VPNs) can help optimize firewall placement throughout the organization. Determining which kinds of traffic inspection are necessary. Different types of network connections require different levels of security. For example, a public-facing Wi-Fi router is far more likely to encounter malicious traffic than an internal virtual local area network (VLAN) that only authenticated employees can access. How to choose between host-based firewalls and network-based firewalls when moving to the cloud Organizations that are transitioning to cloud infrastructure need to completely rethink their firewall deployment strategy. Firewalls are the cornerstone of access control, and cloud-hosted infrastructure comes with the shared responsibility model that puts pressure on security leaders to carefully deploy security resources. In many cases, you’ll face tough decisions concerning which type of firewall to deploy at particular points in your network. Building an optimal deployment means working through the pros and cons of each option on a case-by-case basis. Host-based firewalls and network-based firewalls are the two main options you’ll encounter for most use cases. Let’s look at what each of those options look like from a complete network security perspective . 1. Host-based firewalls offer flexibility but may introduce vulnerabilities A cloud-native organization that exclusively uses host-based firewalls will have a cloud environment filled with virtual machines that take the place of servers and individual computers. To protect those devices, the organization will implement host-based firewalls on every virtual machine and configure them accordingly. This provides the organization with a great deal of flexibility. IT team members can clone virtual machines and move them within the cloud on demand. The host-based firewalls that protect these machines can move right alongside them, ensuring consistent security policies are enforced without painstaking manual configuration. It’s even possible to move virtual machines between cloud environments – like moving a virtual server from Amazon AWS to Microsoft Azure – without having to create completely new security policies in the process. This makes it easy for IT teams to work securely without introducing friction. However, if attackers gain privileged access to host-based firewalls, they gain the same level of control. They may switch off the firewall or install malicious code in ways that other security technologies cannot detect. Even highly secure organizations are subject to this kind of risk. Imagine an attacker compromises the credentials of a system administrator with firewall configuration privileges. Very few obstacles stand between an insider threat and the sensitive data they wish to exfiltrate. Network-based firewalls offer independent security Compared to host-based firewall products, it’s much harder for a malicious insider to compromise a network-based firewall solution managed by a cloud provider. That’s because the physical hardware is operating on a completely separate system from the host. In a cloud-native environment, the network-based firewall would be a fully hardened device managed by a third-party provider running their own intrusion detection systems. This makes it much harder for attackers to successfully infiltrate and compromise systems without being noticed. At the same time, independent network-based firewall architecture means that the attacker would have to compromise both your network and the cloud provider’s network without triggering security alerts from either. This adds a great deal of complexity to any attack, and significantly increases the chance it will be detected. However, few organizations can afford to exclusively deploy hardware firewalls at every layer of their network. Even those that can afford it will run into significant challenges when planning for growth and scalability. Segment your network for optimal protection While they offer increased security, hardware firewalls are costly to deploy and maintain. Most organizations segment their networks in ways that offer extensive multi-layered protection to their most sensitive data while allowing more flexible host-based firewalls to protect less critical assets. Every organization has a unique balance between optimal network-based firewall and host-based firewall deployment. This depends heavily on the volume of sensitive data the organization regularly accesses, and the security of its connections with users and third-party service providers. Proper network segmentation helps reduce the organization’s attack surface and decrease the risk of business disruption.

Cyber Attacks & Incident Response Stop hackers from poisoning the well: Protecting critical infrastructure against cyber-attacks Tsippi Dach 2 min read Tsippi Dach 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 3/31/21 Published Attacks on water treatment plants show just how vulnerable critical infrastructure is to hacking – here’s how these vital services should be protected. Criminals plotting to poison a city’s water supply is a recurring theme in TV and movie thrillers, such as 2005’s Batman Begins. But as we’ve seen recently, it’s more than just a plot device: it’s a cyber-threat which is all too real. During the past 12 months, there have been two high-profile attacks on water treatment systems that serve local populations, both with the aim of causing harm to citizens. The first was in April 2020, targeting a plant in Israel . Intelligence sources said that hackers gained access to the plant and tried altering the chlorine levels in drinking water – but luckily the attack was detected and stopped. And in early February, a hacker gained access to the water system of Oldsmar, Florida and tried to pump in a dangerous amount of sodium hydroxide. The hacker succeeded in starting to add the chemical, but luckily a worker spotted what was happening and reversed the action. But what could have happened if those timely interventions had not been made? These incidents are a clear reminder that critical national infrastructure is vulnerable to attacks – and that those attacks will keep on happening, with the potential to impact the lives of millions of people.  And of course, the Covid-19 pandemic has further highlighted how essential critical infrastructure is to our daily lives. So how can better security be built into critical infrastructure systems, to stop attackers being able to breach them and disrupt day-to-day operations?  It’s a huge challenge, because of the variety and complexity of the networks and systems in use across different industry sectors worldwide. Different systems but common security problems For example, in water and power utilities, there are large numbers of cyber-physical systems consisting of industrial equipment such as turbines, pumps and switches, which in turn are managed by a range of different industrial control systems (ICS). These were not designed with security in mind:  they are simply machines with computerized controllers that enact the instructions they receive from operators.  The communications between the operator and the controllers are done via IP-based networks – which, without proper network defenses, means they can be accessed over the Internet – which is the vector that hackers exploit. As such, irrespective of the differences between ICS controls, the security challenges for all critical infrastructure organizations are similar:  hackers must be stopped from being able to infiltrate networks; if they do succeed in breaching the organization’s defenses, they must be prevented from being able to move laterally across networks and gain access to critical systems. This means  network segmentation  is one of the core strategies for securing critical infrastructure, to keep operational systems separate from other networks in the organization and from the public Internet and surround them with security gateways so that they cannot be accessed by unauthorized people. In the attack examples we mentioned earlier, properly implemented segmentation would prevent a hacker from being able to access the PC which controls the water plant’s pumps and valves. With damaging ransomware attacks increasing over the past year, which also exploit internal network connections and pathways to spread rapidly and cause maximum disruption,  organizations should also employ security best-practices to block or limit the impact of ransomware attacks  on their critical systems. These best practices have not changed significantly since 2017’s massive WannaCry and NotPetya attacks, so organizations would be wise to check and ensure they are employing them on their own networks. Protecting critical infrastructure against cyber-attacks is a complex challenge because of the sheer diversity of systems in each sector.  However, the established security measures we’ve outlined here are extremely effective in protecting these vital systems – and in turn, protecting all of us.

Tags Share this article 11/11/24 Published Secure VPC as the main pillar of cloud security Remember the Capital One breach back in 2019 ? 100 million customers' data exposed, over $270 million in fines – all because of a misconfigured WAF. Ouch! A brutal reminder that cloud security is no joke. And with cloud spending skyrocketing to a whopping $675.4 billion this year, the bad guys are licking their chops. The stakes? Higher than ever. The cloud's a dynamic beast, constantly evolving, with an attack surface that's expanding faster than a pufferfish in a staring contest. To stay ahead of those crafty cybercriminals, you need a security strategy that's as agile as a ninja warrior. That means a multi-layered approach, with network security as the bedrock. Think of it as the backbone of your cloud fortress, ensuring all your communication channels – internal and external – are locked down tighter than Fort Knox. In this post, we're shining the spotlight on Virtual Private Clouds (VPCs) – the cornerstone of your cloud network security. But here's the kicker: native cloud tools alone won't cut it. They're like a bicycle in a Formula 1 race – good for a leisurely ride, but not built for high-speed security. We'll delve into why and introduce you to AlgoSec, the solution that turbocharges your VPC security and puts you in the driver's seat. The 5 Pillars of Cloud Security: A Quick Pit Stop Before we hit the gas on VPCs, let's do a quick pit stop to recap the five foundational pillars of a rock-solid cloud security strategy: Identity and Access Management (IAM): Control who gets access to what with the principle of least privilege and role-based access control. Basically, don't give the keys to the kingdom to just anyone! Keep a watchful eye with continuous monitoring and logging of access patterns. Integrate with SIEM systems to boost your threat detection and response capabilities. Think of it as having a security guard with night vision goggles patrolling your cloud castle 24/7. Data Encryption: Protect your sensitive data throughout its lifecycle – whether it's chilling in your cloud servers or traveling across networks. Think of it as wrapping your crown jewels in multiple layers of security, making them impenetrable to those data-hungry thieves. Network Security: This is where VPCs take center stage! But it's more than just VPCs – you also need firewalls, security groups, and constant vigilance to keep your network fortress impenetrable. It's like having a multi-layered defense system with moats, drawbridges, and archers ready to defend your cloud kingdom. Compliance and Governance: Don't forget those pesky regulations and internal policies! Use audit trails, resource tagging, and Infrastructure as Code (IaC) to stay on the right side of the law. It's like having a compliance officer who keeps you in check and ensures you're always playing by the rules. Incident Response and Recovery: Even with the best defenses, breaches can happen. It's like a flat tire on your cloud journey – annoying, but manageable with the right tools. Be prepared with real-time threat detection, automated response, and recovery plans that'll get you back on your feet faster than a cheetah on Red Bull. Why Network Security is Your First Line of Defense Network security is like the moat around your cloud castle, the first line of defense against those pesky attackers. Breaches can cost you a fortune, ruin your reputation faster than a bad Yelp review, and send your customers running for the hills. Remember when Equifax suffered a massive data breach in 2017 due to an unpatched vulnerability? Or the ChatGPT breach in 2023 where a misconfigured database exposed sensitive user data? These incidents are stark reminders that even a small slip-up can have massive consequences. VPCs: Building Your Secure Cloud Fortress VPCs are like creating your own private kingdom within the vast public cloud. You get to set the rules, control access, and keep those unwanted visitors out. This isolation is crucial for preventing those sneaky attackers from gaining a foothold and wreaking havoc. With VPCs, you have granular control over your network traffic – think of it as directing the flow of chariots within your kingdom. You can define routing tables, create custom IP address ranges, and isolate different sections of your cloud environment. But here's the thing: VPCs alone aren't enough. You still need to connect to the outside world, and that's where secure options like VPNs and dedicated interconnects come in. Think of them as secure tunnels and bridges that allow safe passage in and out of your kingdom. Native Cloud Tools: Good, But Not Good Enough The cloud providers offer their own security tools – think AWS CloudTrail, Azure Security Center, and Google Cloud's Security Command Center. They're a good starting point, like a basic toolkit for your cloud security needs. But they often fall short when it comes to dealing with the complexities of today's cloud environments. Here's why: Lack of Customization: They're like one-size-fits-all suits – they might kinda fit, but they're not tailored to your specific needs. You need a custom-made suit of armor for your cloud kingdom, not something off the rack. Blind Spots in Multi-Cloud Environments: If you're juggling multiple cloud platforms, these tools can leave you with blind spots, making it harder to keep an eye on everything. It's like trying to guard a castle with multiple entrances and only having one guard. Configuration Nightmares: Misconfigurations are like leaving the back door to your castle wide open. Native tools often lack the robust detection and prevention mechanisms you need to avoid these costly mistakes. You need a security system with motion sensors, alarms, and maybe even a moat with crocodiles to keep those intruders out. Integration Headaches: Trying to integrate these tools with other security solutions can be like fitting a square peg into a round hole. This can leave gaps in your security posture, making you vulnerable to attacks. You need a security system that works seamlessly with all your other defenses, not one that creates more problems than it solves.

Firewall Policy Management 12 Best Network Security Audit Tools + Key Features 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 10/25/23 Published Fortified network security requires getting a variety of systems and platforms to work together. Security teams need to scan for potential threats, look for new vulnerabilities in the network, and install software patches in order to keep these different parts working smoothly. While small organizations with dedicated cybersecurity teams may process these tasks manually at first, growing audit demands will quickly outpace their capabilities. Growing organizations and enterprises rely on automation to improve IT security auditing and make sure their tech stack is optimized to keep hackers out. Network Security Audit Tools Explained Network Security Audit Tools provide at-a-glance visibility into network security operations and infrastructure. They scan network security tools throughout the environment and alert administrators of situations that require their attention. These situations can be anything from emerging threats, newly discovered vulnerabilities, or newly released patches for important applications. Your network security audit tools provide a centralized solution for managing the effectiveness of your entire security tech stack – including cloud-based software solutions and on-premises tools alike. With such a wide set of responsibilities, it should come as no surprise that many audit tools differ widely from one another. Some are designed for easy patch management while others may focus on intrusion detection or sensitive data exfiltration. Major platforms and operating systems may even include their own built-in audit tools. Microsoft Windows has an audit tool that focuses exclusively on Active Directory. However, enterprise security teams don’t want to clutter their processes with overlapping tools and interfaces – they want to consolidate their auditing tools onto platforms that allow for easy management and oversight. Types of Network Security Audit Tools Firewall Auditing Tools Firewall security rules provide clear instructions to firewalls on what kind of traffic is permitted to pass through. Firewalls can only inspect connections they are configured to detect . These rules are not static , however. Since the cybersecurity threat landscape is constantly changing, firewall administrators must regularly update their policies to accommodate new types of threats. At the same time, threat actors who infiltrate firewall management solutions can gain a critical advantage over their targets. They can change the organization’s security policies to ignore whatever malicious traffic they are planning on using to compromise the network. If these changes go unnoticed, even the best security technologies won’t be able to detect or respond to the threat. Security teams must regularly evaluate their firewall security policies to make sure they are optimized for the organization’s current risk profile. This means assessing the organization’s firewall rules and determining whether it is meeting its security needs. The auditing process may reveal overlapping rules, unexpected configuration changes , or other issues. Vulnerability Scanners Vulnerability scanners are automated tools that create an inventory of all IT assets in the organization and scan those assets for weak points that attackers may exploit. They also gather operational details of those assets and use that information to create a comprehensive map of the network and its security risk profile. Even a small organization may have thousands of assets. Hardware desktop workstations, laptop computers, servers, physical firewalls, and printers all require vulnerability scanning. Software assets like applications , containers, virtual machines, and host-based firewalls must also be scanned. Large enterprises need scanning solutions capable of handling enormous workloads rapidly. These tools provide security teams with three key pieces of information: Weaknesses that hackers know how to exploit . Vulnerability scanners work based on known threats that attackers have exploited in the past. They show security teams exactly where hackers could strike, and how. The degree of risk associated with each weakness . Since scanners have comprehensive information about every asset in the network, they can also predict the damage that might stem from an attack. This allows security teams to focus on high-priority risks first. Recommendations on how to address each weakness . The best vulnerability scanners provide detailed reports with in-depth information on how to mitigate potential threats. This gives security personnel step-by-step information on how to improve the organization’s security posture. Penetration Testing Tools Penetration testing allows organizations to find out how resilient their assets and processes might be in the face of an active cyberattack. Penetration testers use the same tools and techniques hackers use to exploit their victims, showing organizations whether their security policies actually work. Traditionally, penetration testing is carried out by two teams of cybersecurity professionals. The “red team” attempts to infiltrate the network and access sensitive data while the “blue team” takes on defense. Cybersecurity professionals should know how to use the penetration testing tools employed by hackers and red team operatives. Most of these tools have legitimate uses and are a fixture of many IT professionals’ toolkits. Some examples include: Port scanners . These identify open ports on a particular system. This can help users identify the operating system and find out what applications are running on the network. Vulnerability scanners . These search for known vulnerabilities in applications, operating systems, and servers. Vulnerability reports help penetration testers identify the most reliable entry point into a protected network. Network analyzers . Also called network sniffers, these tools monitor the data traveling through the network. They can provide penetration testers with information about who is communicating over the network, and what protocols and ports they are using. These tools help security professionals run security audits by providing in-depth data on how specific attack attempts might play out. Additional tools like web proxies and password crackers can also play a role in penetration testing, providing insight into the organization’s resilience against known threats. Key Functionalities of Network Security Audit Software Comprehensive network security audit solutions should include the following features: Real-time Vulnerability Assessment Network Discovery and Assessment Network Scanning for Devices and IP Addresses Identifying Network Vulnerabilities Detecting Misconfigurations and Weaknesses Risk Management Customizable Firewall Audit Templates Endpoint Security Auditing Assessing Endpoint Security Posture User Account Permissions and Data Security Identifying Malware and Security Threats Compliance Auditing Generating Compliance Audit Reports Compliance Standards and Regulations PCI DSS HIPAA GDPR NIST Integration and Automation with IT Infrastructure Notifications and Remediation User Interface and Ease of Use Operating System and Configuration Auditing Auditing Windows and Linux Systems User Permissions and Access Control Top 12 Network Security Audit Tools 1.

Steps to Conduct a Network Security Audit Define the Scope : Start by defining the scope of your audit. You’ll need to determine which parts of your network and systems will be audited. Consider the goals and objectives of the audit, such as identifying vulnerabilities, ensuring compliance, or assessing overall security posture. Gather Information : Collect all relevant information about your network, including network diagrams, asset inventories, and existing security policies and procedures. This information will serve as a baseline for your audit. The more comprehensive this information is, the more accurate your audit results can be. Identify Assets : List all the assets on your network, including servers, routers, switches, firewalls, and endpoints. Ensure that you have a complete inventory of all devices and their configurations. If this information is not accurate, the audit may overlook important gaps in your security posture. Assess Vulnerabilities : Use network vulnerability scanning tools to identify vulnerabilities in your network. Vulnerability scanners like Nessus or OpenVAS can help pinpoint weaknesses in software, configurations, or missing patches. This process may take a long time if it’s not supported by automation. Penetration Testing : Conduct penetration testing to simulate cyberattacks and assess how well your network defenses hold up. Penetration testing tools like Metasploit or Burp Suite can help identify potential security gaps. Automation can help here, too – but the best penetration testing services emulate the way hackers work in the real world. Review Policies and Procedures : Evaluate the results of your vulnerability and penetration testing initiatives. Review your existing security policies and procedures to ensure they align with best practices and compliance requirements. Make necessary updates or improvements based on audit findings. Log Analysis : Analyze network logs to detect any suspicious or unauthorized activities. Log analysis tools like Splunk or ELK Stack can help by automating the process of converting log data into meaningful insights. Organizations equipped with SIEM platforms can analyze logs in near real-time and continuously monitor their networks for signs of unauthorized behavior. Review Access Controls : Ensure the organization’s access control policies are optimal. Review user permissions and authentication methods to prevent unauthorized access to critical resources. Look for policies and rules that drag down production by locking legitimate users out of files and folders they need to access. Firewall and Router Configuration Review: Examine firewall and router configurations to verify that they are correctly implemented and that access rules are up to date. Ensure that only necessary ports are open, and that the organization’s firewalls are configured to protect those ports. Prevent hackers from using port scanners or other tools to conduct reconnaissance. Patch Management : Check for missing patches and updates on all network devices and systems. Regularly update and patch software to address known vulnerabilities. Review recently patched systems to make sure they are still compatible with the tools and technologies they integrate with. Incident Response Plan : Review and update your incident response plan. Ensure the organization is prepared to respond effectively to security incidents, and can rely on up-to-date playbooks in the event of a breach. Compare incident response plans with the latest vulnerability scanning data and emerging threat intelligence information. Documentation and Reporting: Document all audit findings, vulnerabilities, and recommended remediation steps. Generate data visualizations that guide executives and other stakeholders through the security audit process and explain its results. Create a comprehensive report that includes an executive summary, technical details, and prioritized action items. Remediation : Implement the necessary changes and remediation measures to address the identified vulnerabilities and weaknesses. Deploy limited security resources effectively, prioritizing fixes based on their severity. Avoid unnecessary downtime when reconfiguring security tools and mitigating risk. Follow-Up Audits: Schedule regular follow-up audits to ensure that the identified vulnerabilities have been addressed and that security measures are continuously improved. Compare the performance metric data gathered through multiple audits and look for patterns emerging over time. Training and Awareness: Provide training and awareness programs for employees to enhance their understanding of security best practices and their role in maintaining network security. Keep employees well-informed about the latest threats and vulnerabilities they must look out for. FAQs What are some general best practices for network security auditing? Network security audits should take a close look at how the organization handles network configuration management over time. Instead of focusing only on how the organization’s current security controls are performing, analysts should look for patterns that predict how the organization will perform when new threats emerge in the near future. This might mean implementing real-time monitoring and measuring how long it takes for obsolete rules to get replaced. What is the ideal frequency for conducting network security audits? Network security audits should be conducted at least annually, with more frequent audits recommended for organizations with high-security requirements. Automated policy management platforms like AlgoSec can help organizations audit their security controls continuously. Are network security audit tools effective against zero-day vulnerabilities? Network security audit tools may not detect zero-day vulnerabilities immediately. However, they can still contribute by identifying other weaknesses that could be exploited in tandem with a zero-day vulnerability. They also provide information on how long it takes the organization to recognize new vulnerabilities once they are discovered. What should I look for when choosing a network security audit tool for my organization? Consider factors like the tool’s compatibility with your network infrastructure, reporting capabilities, support and updates, and its track record in identifying vulnerabilities relevant to your industry. Large enterprises highly value scalable tools that support automation. Can network security audit tools help with regulatory compliance? Yes, many audit tools offer compliance reporting features, helping organizations adhere to various industry and government regulations. Without an automated network security audit tool in place, many organizations would be unable to consistently demonstrate compliance. How long does it take to conduct a typical network security audit? The duration of an audit varies depending on the size and complexity of the network. A thorough audit can take anywhere from a few days to several weeks. Continuous auditing eliminates the need to disrupt daily operations when conducting audits, allowing security teams to constantly improve performance. What are the most common mistakes organizations make during network security audits? Common mistakes include neglecting to update audit tools regularly, failing to prioritize identified vulnerabilities, and not involving key stakeholders in the audit process. Overlooking critical assets like third-party user accounts can also lead to inaccurate audit results. What are some important capabilities needed for a Cloud-Based Security Audit? Cloud-based security audits can quickly generate valuable results by scanning the organization’s cloud-hosted IT assets for vulnerabilities and compliance violations. However, cloud-based audit software must be able to recognize and integrate third-party SaaS vendors and their infrastructure. Third-party tools and platforms can present serious security risks, and must be carefully inspected during the audit process. What is the role of Managed Service Providers (MSPs) in Network Security Auditing? MSPs can use audits to demonstrate the value of their services and show customers where improvement is needed. Since this improvement often involves the customer drawing additional resources from the MSP, comprehensive audits can improve the profitability of managed service contracts and deepen the connection between MSPs and their customers.

Cloud Security Prevasio’s Role in Red Team Exercises and Pen Testing 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 12/21/20 Published Cybersecurity is an ever prevalent issue. Malicious hackers are becoming more agile by using sophisticated techniques that are always evolving. This makes it a top priority for companies to stay on top of their organization’s network security to ensure that sensitive and confidential information is not leaked or exploited in any way. Let’s take a look at the Red/Blue Team concept, Pen Testing, and Prevasio’s role in ensuring your network and systems remain secure in a Docker container atmosphere. What is the Red/Blue Team Concept? The red/blue team concept is an effective technique that uses exercises and simulations to assess a company’s cybersecurity strength. The results allow organizations to identify which aspects of the network are functioning as intended and which areas are vulnerable and need improvement. The idea is that two teams (red and blue) of cybersecurity professionals face off against each other. The Red Team’s Role It is easiest to think of the red team as the offense. This group aims to infiltrate a company’s network using sophisticated real-world techniques and exploit potential vulnerabilities. It is important to note that the team comprises highly skilled ethical hackers or cybersecurity professionals. Initial access is typically gained by stealing an employee’s, department, or company-wide user credentials. From there, the red team will then work its way across systems as it increases its level of privilege in the network. The team will penetrate as much of the system as possible. It is important to note that this is just a simulation, so all actions taken are ethical and without malicious intent. The Blue Team’s Role The blue team is the defense. This team is typically made up of a group of incident response consultants or IT security professionals specially trained in preventing and stopping attacks. The goal of the blue team is to put a stop to ongoing attacks, return the network and its systems to a normal state, and prevent future attacks by fixing the identified vulnerabilities. Prevention is ideal when it comes to cybersecurity attacks. Unfortunately, that is not always possible. The next best thing is to minimize “breakout time” as much as possible. The “breakout time” is the window between when the network’s integrity is first compromised and when the attacker can begin moving through the system. Importance of Red/Blue Team Exercises Cybersecurity simulations are important for protecting organizations against a wide range of sophisticated attacks. Let’s take a look at the benefits of red/blue team exercises: Identify vulnerabilities Identify areas of improvement Learn how to detect and contain an attack Develop response techniques to handle attacks as quickly as possible Identify gaps in the existing security Strengthen security and shorten breakout time Nurture cooperation in your IT department Increase your IT team’s skills with low-risk training What are Pen Testing Teams? Many organizations do not have red/blue teams but have a Pen Testing (aka penetration testing) team instead. Pen testing teams participate in exercises where the goal is to find and exploit as many vulnerabilities as possible. The overall goal is to find the weaknesses of the system that malicious hackers could take advantage of. Companies’ best way to conduct pen tests is to use outside professionals who do not know about the network or its systems. This paints a more accurate picture of where vulnerabilities lie. What are the Types of Pen Testing? Open-box pen test – The hacker is provided with limited information about the organization. Closed-box pen test – The hacker is provided with absolutely no information about the company. Covert pen test – In this type of test, no one inside the company, except the person who hires the outside professional, knows that the test is taking place. External pen test – This method is used to test external security. Internal pen test – This method is used to test the internal network. The Prevasio Solution Prevasio’s solution is geared towards increasing the effectiveness of red teams for organizations that have taken steps to containerize their applications and now rely on docker containers to ship their applications to production. The benefits of Prevasio’s solution to red teams include: Auto penetration testing that helps teams conduct break-and-attack simulations on company applications. It can also be used as an integrated feature inside the CI/CD to provide reachability assurance. The behavior analysis will allow teams to identify unintentional internal oversights of best practices. The solution features the ability to intercept and scan encrypted HTTPS traffic. This helps teams determine if any credentials should not be transmitted. Prevasio container security solution with its cutting-edge analyzer performs both static and dynamic analysis of the containers during runtime to ensure the safest design possible. Moving Forward Cyberattacks are as real of a threat to your organization’s network and systems as physical attacks from burglars and robbers. They can have devastating consequences for your company and your brand. The bottom line is that you always have to be one step ahead of cyberattackers and ready to take action, should a breach be detected. The best way to do this is to work through real-world simulations and exercises that prepare your IT department for the worst and give them practice on how to respond. After all, it is better for your team (or a hired ethical hacker) to find a vulnerability before a real hacker does. Simulations should be conducted regularly since the technology and methods used to hack are constantly changing. The result is a highly trained team and a network that is as secure as it can be. Prevasio is an effective solution in conducting breach and attack simulations that help red/blue teams and pen testing teams do their jobs better in Docker containers.
