Cloud Security Understanding and Preventing Kubernetes Attacks and Threats Ava Chawla 5 min read Ava Chawla 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 10/20/21 Published As the most widely adapted open-source container software, Kubernetes provides businesses with efficient processes to schedule, deploy, and scale containers across different machines. The bad news is that cybercriminals have figured out how to exploit the platform’s vulnerabilities , resulting in catastrophic network intrusions across many company infrastructures. A recent report revealed that 94% of respondents reported security incidents in Kubernetes environments. The question is, what is behind this surge of Kubernetes attacks, and how can they be prevented? How Kubernetes is Vulnerable As a container-based platform, a new set of vulnerabilities, permission issues, and specific images set the stage for the increase in attacks. The threats have included fileless malware in containers, leveraging misconfigured Docker API ports, and using container images for attacks. Misconfigured Docker API Ports Exploitation Scanning for misconfigured Docker API ports and using them for deploying images containing malware is a relatively new type of attack. The malware, designed to evade static scanning, has become a popular method to hijack compute cycles for fraudulent cryptomining. This cryptojacking activity steals CPU power to mine currencies such as Ethereum and Monero. By first identifying vulnerable front-end websites and other systems, attackers send a command through the application layer simply by manipulating a domain’s text field or through an exposed API in the website’s URL. The code then enters the container, where it is executed with commands sent to a Docker container’s shell. A wget command is executed to download the malware. To protect against this attack, enterprises must ensure their container files are not writable, establish CPU consumption limits, and enable alerts to detect interactive shell launches. DDoS Attacks With Open Docker Daemons Cybercriminals use misconfigured open Docker daemons to launch DDoS attacks using a botnet of containers. UDP flood and Slowloris were recently identified as two such types of container-based botnet attacks. A recent blog describes an anatomy of these Kubernetes attacks. The attackers first identified open Docker daemons using a scanning tool such as Shodan to scan the internet for IP addresses and find a list of hosts, open ports, and services. By uploading their own dedicated images to the Docker hub, they succeeded in deploying and remotely running the images on the host. Analyzing how the UDP flood attack was orchestrated required an inspection of the binary with IDA. This revealed the start_flood and start_tick threads. The source code for the attack was found on Github. This code revealed a try_gb parameter, with the range of 0 to 1,024, used to configure how much data to input to flood the target. However, it was discovered that attackers are able to modify this open-source code to create a self-compiled binary that floods the host with even greater amounts of UDP packets. In the case of the Slowloris attack, cybercriminals launched DDoS with the slowhttptest utility. The attackers were able to create a self-compiling binary that is unidentifiable in malware scans. Protection from these Kubernetes attacks requires vigilant assurance policies and prevention of images other than compliant ones to run in the system. Non-compliant images will then be blocked when intrusion attempts are made. Man in the Middle Attacks With LoadBalancer or ExternalIPs An attack affecting all versions of Kubernetes involves multi-tenant clusters. The most vulnerable clusters have tenants that are able to create and update services and pods. In this breach, the attacker can intercept traffic from other pods or nodes in the cluster by creating a ClusterIP service and setting the spec.externalIP’s field. Additionally, a user who is able to patch the status of a LoadBalancer service can grab traffic. The only way to mitigate this threat is to restrict access to vulnerable features. This can be done with the admission webhook container, externalip-webhook , which prevents services from using random external IPs. An alternative method is to lock external IPs with OPA Gatekeeper with this sample Constraint Templatecan. Siloscape Malware Security researcher, Daniel Prizmant, describes a newer malware attack that he calls Siloscape. Its primary goal is to escape the container that is mainly implemented in Windows server silo. The malware targets Kubernetes through Windows containers to open a backdoor into poorly configured clusters to run the malicious containers. While other malware attacks focus on cryptojacking, the Siloscape user’s motive is to go undetected and open a backdoor to the cluster for a variety of malicious activities. This is possible since Siloscape is virtually undetectable due to a lack of readable strings in the binary. This type of attack can prove catastrophic. It compromises an entire cluster running multiple cloud applications. Cybercriminals can access critical information including sign-ins, confidential files, and complete databases hosted inside the cluster. Additionally, organizations using Kubernetes clusters for testing and development can face catastrophic damage should these environments be breached. To prevent a Siloscape attack, it is crucial that administrators ensure their Kubernetes clusters are securely configured. This will prevent the malware from creating new deployments and force Siloscape to exit. Microsoft also recommends using only Hyper-V containers as a security boundary for anything relying on containerization. The Threat Matrix The MITRE ATT&CK database details additional tactics and techniques attackers are using to infiltrate Kubernetes environments to access sensitive information, mine cryptocurrency, perform DDoS attacks, and other unscrupulous activities. The more commonly used methods are as follows: 1. Kubernetes file compromise Because this file holds sensitive data such as cluster credentials, an attacker could easily gain initial access to the entire cluster. Only accept kubeconfig files from trusted sources. Others should be thoroughly inspected before they are deployed. 2. Using similar pod names Attackers create similar pod names and use random suffixes to hide them in the cluster. The pods then run malicious code and obtain access to many other resources. 3. Kubernetes Secrets intrusion Attackers exploit any misconfigurations in the cluster with the goal of accessing the API server and retrieving information from the Secrets objects. 4. Internal network access Attackers able to access a single pod that communicates with other pods or applications can move freely within the cluster to achieve their goals. 5. Using the writeable hostPath mount Attackers with permissions to create new containers can create one with a writeable hostPath volume. Kubernetes Attacks: Key Takeaways Kubernetes brings many advantages to organizations but also presents a variety of security risks, as documented above. However, by ensuring their environments are adequately protected through proper configuration and appropriately assigned permissions, the threat of Kubernetes attacks is greatly minimized. Should a container be compromised, properly assigned privileges can severely limit a cluster-wide compromise.

Security audits come in two forms: internal and external. In internal audits, a business uses its resources and employees to conduct the investigation. In external audits, a third-party organization is hired to conduct the audit. PAA: How do I become a cloud security auditor? To become a cloud security auditor, you need a certification like the Certificate of Cloud Security Knowledge (CCSK) or Certified Cloud Security Professional (CCSP). Prior experience in IT auditing, cloud security management, and cloud risk assessment is highly beneficial. Cloud environments are used to store over 60 percent of all corporate data as of 2022. With so much data in the cloud, organizations rely on cloud security audits to ensure that cloud services can safely provide on-demand access. In this article, we explain what a cloud security audit is, its main objectives, and its benefits. We’ve also listed the six crucial steps of a cloud audit and a checklist of example actions taken during an audit. What Is a Cloud Security Audit? A cloud security audit is a review of an organization’s cloud security environment . During an audit, the security auditor will gather information, perform tests, and confirm whether the security posture meets industry standards. Cloud service providers (CSPs) offer three main types of services: Software as a Service (SaaS) Infrastructure as a Service (IaaS) Platform as a Service (PaaS) Businesses use these solutions to store data and drive daily operations. A cloud security audit evaluates a CSP’s security and data protection measures. It can help identify and address any risks. The audit assesses how secure, dependable, and reliable a cloud environment is. Cloud audits are an essential data protection measure for companies that store and process data in the cloud. An audit assesses the security controls used by CSPs within the company’s cloud environment. It evaluates the effectiveness of the CSP’s security policies and technical safeguards. Auditors identify vulnerabilities, gaps, or noncompliance with regulations. Addressing these issues can prevent data breaches and exploitation via cybersecurity attacks. Meeting mandatory compliance standards will also prevent potentially expensive fines and being blacklisted. Once the technical investigation is complete, the auditor generates a report. This report states their findings and can have recommendations to optimize security. An audit can also help save money by finding unused or redundant resources in the cloud system. Main Objectives of a Cloud Security Audit The main objective of a cloud security audit is to evaluate the health of your cloud environment, including any data and applications hosted on the cloud. Other important objectives include: Decide the information architecture: Audits help define the network, security, and systems requirements to secure information. This includes data at rest and in transit. Align IT resources: A cloud audit can align the use of IT resources with business strategies. Identify risks: Businesses can identify risks that could harm their cloud environment. This could be security vulnerabilities, data access errors, and noncompliance with regulations. Optimize IT processes: An audit can help create documented, standardized, and repeatable processes, leading to a secure and reliable IT environment. This includes processes for system ownership, information security, network access, and risk management. Assess vendor security controls: Auditors can inspect the CSP’s security control frameworks and reliability. What Are the Two Types of Cloud Security Audits? Security audits come in two forms: internal and external. In internal audits, a business uses its resources and employees to conduct the investigation. In external audits, a third-party organization is hired to conduct the audit. The internal audit team reviews the organization’s cloud infrastructure and data. They aim to identify any vulnerabilities or compliance issues. A third-party auditor will do the same during an external audit. Both types of audits provide an objective assessment of the security posture . But internal audits are rare since there is a higher chance of prejudice during analysis. Who Provides Cloud Security Audits? Cloud security assessments are provided by: Third-party auditors: Independent third-party audit firms that specialize in auditing cloud ecosystems. These auditors are often certified and experienced in CSP security policies. They also use automated and manual security testing methods for a comprehensive evaluation. Some auditing firms extend remediation support after the audit. Cloud service providers: Some cloud platforms offer auditing services and tools. These tools vary in the depth of their assessments and the features they provide to fix problems. Internal audit teams: Many organizations use internal audit teams. These teams assess the controls and processes using CSPM tools . They provide recommendations for improving security and mitigating risks. Why Cloud Security Audits Are So Important Here are eight ways in which security audits of cloud services are performed: Identify security risks: An audit can identify potential security risks. This includes weaknesses in the cloud infrastructure, apps, APIs, or data. Recognizing and fixing these risks is critical for data protection. Ensure compliance: Audits help the cloud environment comply with regulations like HIPAA, PCI DSS, and ISO 27001. Compliance with these standards is vital for avoiding legal and financial penalties. Optimize cloud processes: An audit can help create efficient processes using fewer resources. There is also a decreased risk of breakdowns or malfunctions. Manage access control: Employees constantly change positions within the company or leave. With an audit, businesses can ensure that everyone has the right level of access. For example, access is completely removed for former employees. Auditing access control verifies if employees can safely log in to cloud systems. This is done via two-step authentication, multi-factor authentication, and VPNs. Assess third-party tools: Multi-vendor cloud systems include many third-party tools and API integrations. An audit of these tools and APIs can check if they are safe. It can also ensure that they do not compromise overall security. Avoid data loss: Audits help companies identify areas of potential data loss. This could be during transfer or backup or throughout different work processes. Patching these areas is vital for data safety. Check backup safety: Cloud vendors offer services to back up company data regularly. An audit of backup mechanisms can ensure they are performed at the right frequency and without any flaws. Proactive risk management: Organizations can address potential risks before they become major incidents. Taking proactive action can prevent data breaches, system failures, and other incidents that disrupt daily operations. Save money: Audits can help remove obsolete or underused resources in the cloud. Doing this saves money while improving performance. Improve cloud security posture: Like an IT audit, a cloud audit can help improve overall data confidentiality, integrity, and availability. How Is a Cloud Security Audit Conducted? The exact audit process varies depending on the specific goals and scope. Typically, an independent third party performs the audit. It inspects a cloud vendor’s security posture. It assesses how the CSP implements security best practices and whether it adheres to industry standards. It also evaluates performance against specific benchmarks set before the audit. Here is a general overview of the audit process: Define the scope: The first step is to define the scope of the audit. This includes listing the CSPs, security controls, processes, and regulations to be assessed. Plan the audit: The next step is to plan the audit. This involves establishing the audit team, a timeline, and an audit plan. This plan outlines the specific tasks to be performed and the evaluation criteria. Collect information: The auditor can collect information using various techniques. This includes analytics and security tools, physical inspections, questioning, and observation. Review and analyze: The auditor reviews all the information to evaluate the security posture. Create an audit report: An audit report summarizes findings and lists any issues. It is presented to company management at an audit briefing. The report also provides actions for improvement. Take action: Companies form a team to address issues in the audit report. This team performs remediation actions. The audit process could take 12 weeks to complete. However, it could take longer for businesses to complete the recommended remediation tasks. The schedule may be extended if a gap analysis is required. Businesses can speed up the audit process using automated security tools . This software quickly provides a unified view of all security risks across multiple cloud vendors. Some CSPs, like Amazon Web Services (AWS) and Microsoft Azure, also offer auditing tools. These tools are exclusive to each specific platform. The price of a cloud audit varies based on its scope, the size of the organization, and the number of cloud platforms. For example, auditing one vendor could take four or five weeks. But a complex web with multiple vendors could take more than 12 weeks. 6 Fundamental Steps of a Cloud Security Audit Six crucial steps must be performed in a cloud audit: 1. Evaluate security posture Evaluate the security posture of the cloud system . This includes security controls, policies, procedures, documentation, and incident response plans. The auditor can interview IT staff, cloud vendor staff, and other stakeholders to collect evidence about information systems. Screenshots and paperwork are also used as proof. After this process, the auditor analyzes the evidence. They check if existing procedures meet industry guidelines, like the ones provided by Cloud Security Alliance (CSA). 2. Define the attack surface An attack surface includes all possible points, or attack vectors, through which unauthorized users can access and exploit a system. Since cloud solutions are so complex, this can be challenging. Organizations must use cloud monitoring and observability technologies to determine the attack surface. They must also prioritize high-risk assets and focus their remediation efforts on them. Auditors must identify all the applications and assets running within cloud instances and containers. They must check if the organization approves these or if they represent shadow IT. To protect data, all workloads within the cloud system must be standardized and have up-to-date security measures. 3. Implement robust access controls Access management breaches are a widespread security risk. Unauthorized personnel can get credentials to access sensitive cloud data using various methods. To minimize security issues related to unauthorized access, organizations must: Create comprehensive password guidelines and policies Mandate multi-factor authentication (MFA) Use the Principle of Least Privilege Access (PoLP) Restrict administrative rights 4. Strict data sharing standards Organizations must install strong standards for external data access and sharing. These standards dictate how data is viewed and accessed in shared drives, calendars, and folders. Start with restrictive standards and then loosen up restrictions when necessary. External access should not be provided to files and folders containing sensitive data. This includes personally identifiable information (PII) and protected health information (PHI). 5. Use SIEM Security Information and Event Management (SIEM) systems can collect cloud logs in a standardized format. This allows editors to access logs and automatically generates reports necessary for different compliance standards. This helps organizations maintain compliance with industry security standards. 6. Automate patch management Regular security patches are crucial. However, many organizations and IT teams struggle with patch management. To create an efficient patch management process, organizations must: Focus on the most crucial patches first Regularly patch valuable assets using automation Add manual reviews to the automated patching process to ensure long-term security How Often Should Cloud Security Audits Be Conducted? As a general rule of thumb, audits are conducted annually or biannually. But an audit should also be performed when: Mandated by regulatory standards. For example, Level 1 businesses must pass at least one audit per year to remain PCI DSS compliant. There is a higher risk level. Organizations storing sensitive data may need more frequent audits. There are significant changes to the cloud environment. Ultimately, the frequency of audits depends on the organization’s specific needs. The Major Cloud Security Audit Challenges Here are some of the major challenges that organizations may face: Lack of visibility Cloud infrastructures can be complex with many services and applications across different providers. Each cloud vendor has their own security policies and practices. They also provide limited access to operational and forensic data required for auditing. This lack of transparency prevents auditors from accessing pertinent data. To gather all relevant data, IT operations staff must coordinate with CSPs. Auditors must also carefully choose test cases to avoid violating the CSP’s security policies. Encryption Data in the cloud is encrypted using two methods — internal or provider encryption. Internal or on-premise encryption is when organizations encrypt data before it is transferred to the cloud. Provider encryption is when the CSP handles encryption. With on-premise encryption, the primary threat comes from malicious internal actors. In the latter method, any security breach of the cloud provider’s network can harm your data. From an auditing standpoint, it is best to encrypt data and manage encryption keys internally. If the CSP handles the encryption keys, auditing becomes nearly impossible. Colocation Many cloud providers use the same physical systems for multiple user organizations. This increases the security risk. It also makes it challenging for auditors to inspect physical locations. Organizations should use cloud vendors that use mechanisms to prevent unauthorized data access. For example, a cloud vendor must prevent users from claiming administrative rights to the entire system. Lack of standardization Cloud environments have ever-increasing entities for auditors to inspect. This includes managed databases, physical hosts, virtual machines (VMs), and containers. Auditing all these entities can be difficult, especially when there are constant changes to the entities. Standardized procedures and workloads help auditors identify all critical entities within cloud systems. Cloud Security Audit Checklist Here is a cloud security audit checklist with example actions taken for each general control area: The above list is not all-inclusive. Each cloud environment and process involved in auditing it is different. Industry Standards To Guide Cloud Security Audits Industry groups have created security standards to help companies maintain their security posture. Here are the five most recognized standards for cloud compliance and auditing: CSA Security, Trust, & Assurance Registry (STAR): This is a security assurance program run by the CSA. The STAR program is built on three fundamental techniques: CSA’s Cloud Control Matrix (CCM) Consensus Assessments Initiative Questionnaire (CAIQ) CSA’s Code of Conduct for GDPR Compliance CSA also has a registry of CSPs who have completed a self-assessment of their security controls. The program includes guidelines that can be used for cloud audits. ISO/IEC 27017:2015: The ISO/IEC 27017:2015 are guidelines for information security controls in cloud computing environments. ISO/IEC 27018:2019: The ISO/IEC 27018:2019 provides guidelines for protecting PII in public cloud computing environments. MTCS SS 584: Multi-Tier Cloud Security (MTCS) SS 584 is a cloud security standard developed by the Infocomm Media Development Authority (IMDA) of Singapore. The standard has guidelines for CSPs on information security controls.Cloud customers and auditors can use it to evaluate the security posture of CSPs. CIS Foundations Benchmarks: The Center for Internet Security (CIS) Foundations Benchmarks are guidelines for securing IT systems and data. They help organizations of all sizes improve their security posture. Final Thoughts on Cloud Security Audits Cloud security audits are crucial for ensuring your cloud systems are secure and compliant. This is essential for data protection and preventing cybersecurity attacks. Auditors must use modern monitoring and CSPM tools like Prevasio to easily identify vulnerabilities in multi-vendor cloud environments. This software leads to faster audits and provides a unified view of all threats, making it easier to take relevant action. FAQs About Cloud Security Audits How do I become a cloud security auditor? To become a cloud security auditor, you need certification like the Certificate of Cloud Security Knowledge (CCSK) or Certified Cloud Security Professional (CCSP). Prior experience in IT auditing, cloud security management, and cloud risk assessment is highly beneficial. Other certifications like the Certificate of Cloud Auditing Knowledge (CCAK) by ISACA and CSA could also help. In addition, knowledge of security guidelines and compliance frameworks, including PCI DSS, ISO 27001, SOC 2, and NIST, is also required.

Application Connectivity Management How to Make Container Security Threats More Containable Prof. Avishai Wool 4 min read Prof. Avishai Wool 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 9/8/22 Published As cloud adoption and digital transformation increases, more sensitive data from applications is being stored in data containers. This is why effective container security controls to securely manage application connectivity is an absolute must. AlgoSec CTO and Co-Founder, Prof. Avishai Wool provides some useful container security best practices to help you do just that. What is Container Security? Organizations, now more than ever, are adopting container technology. Instead of powering up servers and instances in the cloud, they are using containers to run business applications. Securing these is equally as important as securing other digital assets that the business is dependent on. There are two main pillars to think about: The code: you want to be able to scan the containers and make sure that they are running legitimate code without any vulnerabilities. The network: you need to control access to and from the container (what it can connect to), both inside the same cluster, other clusters, and different parts of the network. How critical is container security to managing application connectivity risks? To understand the role of container security within the overall view of network security, there are three points to consider. First, if you’re only concerned about securing the containers themselves, then you’re looking at nano-segmentation , which involves very granular controls inside the applications. Second, if you’re thinking about a slightly wider scope then you may be more concerned with microsegmentation , where you are segmenting between clusters or between servers in a single environment. Here you will want to enforce security controls that determine the allowable communication between specific endpoints at specific levels. Finally, if the communication needs to go further, from a container inside one cluster within one cloud environment to an asset that’s outside of the data center, then that might need to go through broader segmentation controls such as zoning technologies, security groups or a firewall at the border. So, there are all these layers where you can place network security policies. When you’re looking at a particular connectivity request (say for a new version of an application) from the point of view of a given container you should ask yourself: what is the container connected to? What is it communicating with? Where are those other sides of the connectivity placed? Based on that determination, you will then know which security controls you need to configure to allow that connectivity through the network. How does containerization correlate with application centric security policy management? There are a number of different aspects to the relationship between container security and application security. If an application uses containers to power up workloads then container security is very much an integral part of application security. When you’re adding new functionality to an application, powering up additional containers, asking containers to perform new tasks whereby they need to connect to additional assets, then the connectivity of those containers needs to be secured. And security controls need to be regulated or changed based on what the application needs them to do. Another factor in this relationship is the structure of the application. All the containers that run and support the application are often located in one cluster or a micro-segment of the network. So, much of the communication takes place inside that cluster, between one container or another, all in the same cluster. However, some of it can go to another cluster or somewhere that’s not even containerized. This is actually a good thing from an application point of view as the container structure can be used to understand the application structure as well. Not sure about container orchestration? Here’s what to know Container orchestration is part of a bigger orchestration play which is, in general, related to the concept of infrastructure as code. You want to be able to power up an environment with all the assets it requires, and have it function simultaneously so you can duplicate it. There are various orchestration technologies that can be used to deploy the security policies for containers , which is an excellent way to maintain container-based applications in a consistent and repeatable manner. Then if you need to double it or multiply it by 100, you can get cookie-cutter copies of the same thing. How will container security solutions play out in the future? Organizations today have the technology to enforce security controls at the container level, but these controls are very granular and it’s time-consuming to set policies and enforce them, particularly with issues like staff or skills shortages. Looking ahead, companies are likely to take a hierarchical view where container-based security is controlled at the application level by app owners or developers, and at the broader levels to ensure that the measures deployed throughout the network have the same degree of sophistication. Procedures and tooling are all evolving, so we don’t have a definitive answer as to how this will all end up. What are organizations going to be doing? Where will they place their controls? Who has the power to make the changes? When newer technologies are deployed, customer adoption will be crucial to understanding what makes the most sense. This will be interesting as there will be multiple scenarios to help companies master their security blueprint as we move forward.

Tags Share this article 12/23/20 Published The aim of this post is to provide a very high-level illustration of the DNS Tunneling method used in the SolarWinds supply chain attack . An Attacker compromises SolarWinds company and trojanizes a DLL that belongs to its software. Some of the customers receive the malicious DLL as an update for the SolarWinds Orion software. “Corporation XYZ” receives the malicious and digitally signed DLL via update. SolarWinds Orion software loads the malicious DLL as a plugin. Once activated, the DLL reads a local domain name “local.corp-xyz.com” (a fictious name). The malware encrypts the local domain name and adds it to a long domain name. The long domain name is queried with a DNS server (can be tapped by a passive DNS sensor). The recursive DNS server is not authorized to resolve avsvmcloud[.]com, so it forwards the request. An attacker-controlled authoritative DNS server resolves the request with a wildcard A record. The Attacker checks the victim’s name, then adds a CNAME record for the victim’s domain name. The new CNAME record resolves the long domain name into an IP of an HTTP-based C2 server. The malicious DLL downloads and executes the 2nd stage malware (TearDrop, Cobalt Strike Beacon). A Threat Researcher accesses the passive DNS (pDNS) records. One of the long domain names from the pDNS records is decrypted back into “local.corp-xyz.com”. The Researcher deducts that the decrypted local domain name belongs to “Corporation XYZ”.

Tags Share this article 1/11/24 Published Properly configured firewalls are vital in any comprehensive cybersecurity strategy. However, even the most robust configurations can be vulnerable to exploitation by attackers. No single security measure can offer absolute protection against all cyber threats and data security risks . To mitigate these risks, it’s crucial to understand how cybercriminals exploit firewall vulnerabilities. The more you know about their tactics, techniques, and procedures, the better-equipped you are to implement security policies that successfully block unauthorized access to network assets. In this guide, you’ll understand the common cyber threats that target enterprise firewall systems with the goal of helping you understand how attackers exploit misconfigurations and human vulnerabilities. Use this information to protect your network from a firewall breach. Understanding 6 Tactics Cybercriminals Use to Breach Firewalls 1. DNS Leaks Your firewall’s primary use is making sure unauthorized users do not gain access to your private network and the sensitive information it contains. But firewall rules can go both ways – preventing sensitive data from leaving the network is just as important. If enterprise security teams neglect to configure their firewalls to inspect outgoing traffic, cybercriminals can intercept this traffic and use it to find gaps in your security systems. DNS traffic is particularly susceptible to this approach because it shows a list of websites users on your network regularly visit. A hacker could use this information to create a spoofed version of a frequently visited website. For example, they might notice your organization’s employees visit a third-party website to attend training webinars. Registering a fake version of the training website and collecting employee login credentials would be simple. If your firewall doesn’t inspect DNS data and confirm connections to new IP addresses, you may never know. DNS leaks may also reveal the IP addresses and endpoint metadata of the device used to make an outgoing connection. This would give cybercriminals the ability to see what kind of hardware your organization’s employees use to connect to external websites. With that information in hand, impersonating managed service providers or other third-party partners is easy. Some DNS leaks even contain timestamp data, telling attackers exactly when users requested access to external web assets. How to protect yourself against DNS leaks Proper firewall configuration is key to preventing DNS-related security incidents. Your organization’s firewalls should provide observability and access control to both incoming and outgoing traffic. Connections to servers known for hosting malware and cybercrime assets should be blocked entirely. Connections to servers without a known reputation should be monitored closely. In a Zero Trust environment , even connections to known servers should benefit from scrutiny using an identity-based security framework. Don’t forget that apps can connect to external resources, too. Consider deploying web application firewalls configured to prevent DNS leaks when connecting to third-party assets and servers. You may also wish to update your security policy to require employees to use VPNs when connecting to external resources. An encrypted VPN connection can prevent DNS information from leaking, making it much harder for cybercriminals to conduct reconnaissance on potential targets using DNS data. 2. Encrypted Injection Attacks Older, simpler firewalls analyze traffic by looking at different kinds of data packet metadata. This provides clear evidence of certain denial-of-service attacks, clear violations of network security policy , and some forms of malware and ransomware . They do not conduct deep packet inspection to identify the kind of content passing through the firewall. This provides cybercriminals with an easy way to bypass firewall rules and intrusion prevention systems – encryption . If malicious content is encrypted before it hits the firewall, it may go unnoticed by simple firewall rules. Only next-generation firewalls capable of handling encrypted data packets can determine whether this kind of traffic is secure or not. Cybercriminals often deliver encrypted injection attacks through email. Phishing emails may trick users into clicking on a malicious link that injects encrypted code into the endpoint device. The script won’t decode and run until after it passes the data security threshold posed by the firewall. After that, it is free to search for personal data, credit card information, and more. Many of these attacks will also bypass antivirus controls that don’t know how to handle encrypted data. Task automation solutions like Windows PowerShell are also susceptible to these kinds of attacks. Even sophisticated detection-based security solutions may fail to recognize encrypted injection attacks if they don’t have the keys necessary to decrypt incoming data. How to protect yourself against encrypted injection attacks Deep packet inspection is one of the most valuable features next-generation firewalls provide to security teams. Industry-leading firewall vendors equip their products with the ability to decrypt and inspect traffic. This allows the firewall to prevent malicious content from entering the network through encrypted traffic, and it can also prevent sensitive encrypted data – like login credentials – from leaving the network. These capabilities are unique to next-generation firewalls and can’t be easily replaced with other solutions. Manufacturers and developers have to equip their firewalls with public-key cryptography capabilities and obtain data from certificate authorities in order to inspect encrypted traffic and do this. 3. Compromised Public Wi-Fi Public Wi-Fi networks are a well-known security threat for individuals and organizations alike. Anyone who logs into a password-protected account on public Wi-Fi at an airport or coffee shop runs the risk of sending their authentication information directly to hackers. Compromised public Wi-Fi also presents a lesser-known threat to security teams at enterprise organizations – it may help hackers breach firewalls. If a remote employee logs into a business account or other asset from a compromised public Wi-Fi connection, hackers can see all the data transmitted through that connection. This may give them the ability to steal account login details or spoof endpoint devices and defeat multi-factor authentication. Even password-protected private Wi-Fi connections can be abused in this way. Some Wi-Fi networks still use outdated WEP and WPA security protocols that have well-known vulnerabilities. Exploiting these weaknesses to take control of a WEP or WPA-protected network is trivial for hackers. The newer WPA2 and WPA3 standards are much more resilient against these kinds of attacks. While public Wi-Fi dangers usually bring remote workers and third-party service vendors to mind, on-premises networks are just as susceptible. Nothing prevents a hacker from gaining access to public Wi-Fi networks in retail stores, receptions, or other areas frequented by customers and employees. How to protect yourself against compromised public Wi-Fi attacks First, you must enforce security policies that only allow Wi-Fi traffic secured by WPA2 and WPA3 protocols. Hardware Wi-Fi routers that do not support these protocols must be replaced. This grants a minimum level of security to protected Wi-Fi networks. Next, all remote connections made over public Wi-Fi networks must be made using a secure VPN. This will encrypt the data that the public Wi-Fi router handles, making it impossible for a hacker to intercept without gaining access to the VPN’s secret decryption key. This doesn’t guarantee your network will be safe from attacks, but it improves your security posture considerably. 4. IoT Infrastructure Attacks Smartwatches, voice-operated speakers, and many automated office products make up the Internet of Things (IoT) segment of your network. Your organization may be using cloud-enriched access control systems, cost-efficient smart heating systems, and much more. Any Wi-Fi-enabled hardware capable of automation can safely be included in this category. However, these devices often fly under the radar of security team’s detection tools, which often focus on user traffic. If hackers compromise one of these devices, they may be able to move laterally through the network until they arrive at a segment that handles sensitive information. This process can take time, which is why many incident response teams do not consider suspicious IoT traffic to be a high-severity issue. IoT endpoints themselves rarely process sensitive data on their own, so it’s easy to overlook potential vulnerabilities and even ignore active attacks as long as the organization’s mission-critical assets aren’t impacted. However, hackers can expand their control over IoT devices and transform them into botnets capable of running denial-of-service attacks. These distributed denial-of-service (DDoS) attacks are much larger and more dangerous, and they are growing in popularity among cybercriminals. Botnet traffic associated with DDoS attacks on IoT networks has increased five-fold over the past year , showing just how promising it is for hackers. How to protect yourself against IoT infrastructure attacks Proper network segmentation is vital for preventing IoT infrastructure attacks . Your organization’s IoT devices should be secured on a network segment that is isolated from the rest of the network. If attackers do compromise the entire network, you should be protected from the risk of losing sensitive data from critical business assets. Ideally, this protection will be enforced with a strong set of firewalls managing the connection between your IoT subnetwork and the rest of your network. You may need to create custom rules that take your unique security risk profile and fleet of internet-connected devices into account. There are very few situations in which one-size-fits-all rulemaking works, and this is not one of them. All IoT devices – no matter how small or insignificant – should be protected by your firewall and other cybersecurity solutions . Never let these devices connect directly to the Internet through an unsecured channel. If they do, they provide attackers with a clear path to circumvent your firewalls and gain access to the rest of your network with ease. 5. Social Engineering and Phishing Social engineering attacks refer to a broad range of deceptive practices used by hackers to gain access to victims’ assets. What makes this approach special is that it does not necessarily depend on technical expertise. Instead of trying to hack your systems, cybercriminals are trying to hack your employees and company policies to carry out their attacks. Email phishing is one of the most common examples. In a typical phishing attack , hackers may spoof an email server to make it look like they are sending emails from a high-level executive in the company you work for. They can then impersonate this executive and demand junior accountants pay fictitious invoices or send sensitive customer data to email accounts controlled by threat actors. Other forms of social engineering can use your organization’s tech support line against itself. Attackers may pretend to represent large customer accounts and will leverage this ruse to gain information about how your company works. They may impersonate a third-party vendor and request confidential information that the vendor would normally have access to. These attacks span the range from simple trickery to elaborate confidence scams. Protecting against them can be incredibly challenging, and your firewall capabilities can make a significant difference in your overall state of readiness. How to protect yourself against social engineering attacks Employee training is the top priority for protecting against social engineering attacks . When employees understand the company’s operating procedures and security policies, it’s much harder for social engineers to trick them. Ideally, training should also include in-depth examples of how phishing attacks work, what they look like, and what steps employees should take when contacted by people they don’t trust. 6. Sandbox Exploits Many organizations use sandbox solutions to prevent file-based malware attacks. Sandboxes work by taking suspicious files and email attachments and opening them in a secure virtual environment before releasing them to users. The sandbox solution will observe how the file behaves and quarantine any file that shows malicious activity. In theory, this provides a powerful layer of defense against file-based attacks. But in practice, cybercriminals are well aware of how to bypass these solutions. For example, many sandbox solutions can’t open files over a certain size. Hackers who attach malicious code to large files can easily get through. Additionally, many forms of malware do not start executing malicious tasks the second they are activated. This delay can provide just enough of a buffer to get through a sandbox system. Some sophisticated forms of malware can even detect when they are being run in a sandbox environment – and will play the part of an innocent program until they are let loose inside the network. How to protect yourself against sandbox exploits Many next-generation firewalls include cloud-enabled sandboxing capable of running programs of arbitrary size for a potentially unlimited amount of time. More sophisticated sandbox solutions go to great lengths to mimic the system specifications of an actual endpoint so malware won’t know it is being run in a virtual environment. Organizations may also be able to overcome the limitations of the sandbox approach using Content Disarm and Reconstruction (CDR) techniques. This approach keeps potentially malicious files off the network entirely and only allows a reconstructed version of the file to enter the network. Since the new file is constructed from scratch, it will not contain any malware that may have been attached to the original file.

- Cloud Security Alliance Releases Latest Survey Report on State of Cloud Security Concerns, Challenges, and Incidents
Survey finds that 58% of respondents are concerned about security in the cloud, while misconfigurations are one of the leading causes of breaches and outages as public cloud adoption doubles over past two years Cloud Security Alliance Releases Latest Survey Report on State of Cloud Security Concerns, Challenges, and Incidents Survey finds that 58% of respondents are concerned about security in the cloud, while misconfigurations are one of the leading causes of breaches and outages as public cloud adoption doubles over past two years March 30, 2021 Speak to one of our experts SEATTLE – March 30, 2021 – The Cloud Security Alliance (CSA), the world’s leading organization dedicated to defining and raising awareness of best practices to help ensure a secure cloud computing environment, and AlgoSec , a leading provider of business-driven network and cloud security management solutions, today announced the results of a new study titled, “ State of Cloud Security Concerns, Challenges, and Incidents .” The survey, which queried nearly 1,900 IT and security professionals from a variety of organization sizes and locations, sought to gain deeper insight into the complex cloud environment that continues to emerge and that has only grown more complex since the onset of the pandemic. The survey found that over half of organizations are running 41 percent or more of their workloads in public clouds, compared to just one-quarter in 2019. In 2021, 63 percent of respondents expect to be running 41 percent or more of their workloads in public cloud, indicating that adoption of public cloud will only continue. Sixty-two percent of respondents use more than one cloud provider, and the diversity of production workloads (e.g. container platforms, virtual machines) is also expected to increase. Key findings include: Security tops concerns with cloud projects : Respondents’ leading concerns over cloud adoption were network security (58%), a lack of cloud expertise (47%), migrating workloads to the cloud (44%), and insufficient staff to manage cloud environments (32%). It’s notable that a total of 79 percent of respondents reported staff-related issues, highlighting that organizations are struggling with handling cloud deployments and a largely remote workforce. Cloud issues and misconfigurations are leading causes of breaches and outages : Eleven percent of respondents reported a cloud security incident in the past year with the three most common causes being cloud provider issues (26%), security misconfigurations (22%), and attacks such as denial of service exploits (20%). When asked about the impact of their most disruptive cloud outages, 24 percent said it took up to 3 hours to restore operations, and for 26 percent it took more than half a day. Nearly one-third still manage cloud security manually : Fifty-two percent of respondents stated they use cloud-native tools to manage security as part of their application orchestration process, and 50 percent reported using orchestration and configuration management tools such as Ansible, Chef and Puppet. Twenty-nine percent said they use manual processes to manage cloud security. Who controls cloud security is not clear-cut : Thirty-five percent of respondents said their security operations team managed cloud security, followed by the cloud team (18%), and IT operations (16%). Other teams such as network operations, DevOps and application owners all fell below 10 percent, showing confusion over exactly who owns public cloud security. “The use of cloud services has continued to increase over the past decade. Particularly now, in the wake of the COVID-19 public health crisis. With organizations struggling to address a largely remote workforce, many enterprises’ digital transformations have been accelerated to enable employees to work from home,” said Hillary Baron, lead author and research analyst, Cloud Security Alliance. “As an ever-more complex cloud environment continues to evolve, the need for supplementary security tools to improve public cloud security will, as well.” “In the face of complex environments, a dearth of security staff, and an overall lack of cloud knowledge, organizations are turning to security tools that can help supplement their workforce. Three of the top four benefits organizations look for in security management tools involve proactive detection of risks and automation. These types of tools can supplement the challenges many organizations are experiencing with lack of expertise (47%) and staff (32%), as well as improve visibility as they move toward an ever-changing cloud environment,” said Jade Kahn, AlgoSec Chief Marketing Officer.AlgoSec commissioned the survey to add to the industry’s knowledge about hybrid-cloud and multi-cloud security.
