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.

Learn how to effectively prevent and block ransomware attacks using your firewall. Discover essential configurations and best practices for enhanced security. Prevent & block ransomware attacks on firewall What is a ransomware attack? Ransomware is a malware attack that locks a victim’s data and demands a ransom, usually in Bitcoin, for its release. It often spreads through disguised executable files or malicious emails but can also exploit software vulnerabilities. A notable instance is the WannaCry attack, which spread without user interaction. Given the increasing sophistication of these attacks, understanding and combating ransomware is crucial for tightened cybersecurity. Schedule a Demo What are the main types of malware and ransomware threats? Understanding the variants of malware and ransomware infections in cybersecurity is critical to effective prevention and response. These threats can range from viruses to sophisticated Ransomware-as-a-Service models. Let’s delve into the main types: Viruses – Malicious software that can spread to other files and operating systems. Worms – Self-replicating malware spreading independently through networks, causing significant damage. Trojans – Disguised as legitimate software or files, Trojans can steal data or exploit permissions to gain unauthorized system access. Adware – This malware displays unwanted ads or pop-ups on a system, often for the attacker’s revenue generation. Fake pop-ups – Messages claiming your system has a virus and demanding payment for its removal, such as FakeAV and System Progressive Protection. Rootkits – Designed to hide their presence, rootkits enable remote access for malware, making it difficult for antivirus software to detect and remove the threats. Botnets – Attackers use these networks of compromised computers, known as botnets, to carry out remote DDoS and other cyber attacks. Spyware – This malware secretly monitors user activity and collects sensitive data. Fileless malware – Operating entirely in a system’s memory, this malware type is hard to detect and remove. Phishing emails – Disguised emails that trick recipients into clicking a malicious link or opening email attachments that appear authentic. Malvertising – Hackers inject malicious code into legitimate online advertising networks, redirecting users to malicious websites. Drive-by attacks – Users visit unsafe, fake web pages, including sites infected unknowingly or fake sites posing as legitimate ones. Self-propagation – Physically infects a system through a network or USB drive. Encryption ransomware – Encrypts your files and demands payment in return for the decryption key. Examples include CryptoLocker and WannaCry. Locker ransomware – A cyber threat restricting access to your system, demanding payment for restoring access. Winlocker and Police-themed ransomware are examples. Mobile ransomware – Targeting mobile devices, this ransomware locks the device or encrypts the files, demanding payment for their release. Android Defender and Simplelocker are examples. RaaS (Ransomware-as-a-Service) – Distributed as a service, this ransomware model allows anyone to buy or rent ransomware kits or apps for infecting others. Recognizing these threats is the first step toward ransomware prevention . Schedule a Demo Are firewalls able to provide ransomware protection? Yes, firewalls offer a layer of protection against ransomware. They act as a barrier between computers and networks, scanning incoming and outgoing traffic based on defined security parameters to block malicious packets. Firewalls can help thwart ransomware attacks by blocking suspect IP addresses, prohibiting remote access without authorization, and controlling the flow of certain data types that could carry ransomware. Schedule a Demo Which firewall rules can block ransomware? Several firewall rules can help block ransomware: Block known malicious IP addresses – You can configure firewalls to block traffic from IP addresses known to often distribute ransomware. Block all inbound traffic on port 445 – Used for file and printer sharing, port 445 is a common target for ransomware attacks. Restrict outbound traffic – Limiting outbound traffic to necessary ports can prevent a ransomware attack from communicating with its command and control server, thus halting the attack. Implement Geo-IP filtering – Some organizations may find it beneficial to block or limit traffic from specific countries or regions, particularly if they are known sources of ransomware. Disable Remote Desktop Protocol (RDP) – Many ransomware attacks exploit RDP to gain remote access to systems. Disabling RDP at the firewall can help prevent these advanced threats. Implement Intrusion Detection and Prevention Systems (IDS/IPS) – These systems can detect unusual traffic patterns or system activities that suggest a ransomware attack, allowing the firewall to respond and block the attack. Application control – Firewalls with application control features can prevent the execution of unrecognized or unauthorized applications, which can stop the delivery or execution of ransomware. Schedule a Demo What are the best practices for ransomware prevention? Clean up and tighten firewall rules Over time, firewall rules can get messy. This mess might let attackers in, just like weak VPNs or vulnerable email security can. Regularly cleaning up firewall and endpoint protection rules can help stop a ransomware attack . When you change a rule, make sure you know why. Misconfigured changes could disrupt apps or expose VPN tunnels. Analyze the risks and vulnerabilities in your network Every network security solution has some risks. These risks come from different providers. It is essential to find these risks and rank them based on how much they can harm your business. Since threats can pop up anytime, endpoint security with anti-malware features is essential. Focus on risks that could hurt critical business apps. Tying vulnerabilities to related firewall rules can make this easier, just like real-time updates in endpoint security can help stay ahead of new threats. Mitigate lateral movement and control east-west traffic with network segmentation Using network segmentation allows you to minimize the impact on your network in case of an attack. This is particularly effective against swift threats such as zero-day attacks, which target a software vulnerability that is unknown to the software vendor or to antivirus vendors. By securing crucial company data in protected segments with strong encryption keys and employing sandboxing, you are well-equipped to manage east-west traffic. East-west traffic refers to the communication or data transfer that happens inside the network, from server to server, or between internal applications. By managing this traffic, you can prevent attackers from moving laterally across your network. Adding multi-factor authentication can make this strategy even more robust. It adds another layer of security to keep attackers under control. For enhanced protection against cyber threats, consider implementing micro-segmentation . This advanced method can provide granular security controls and can further deter lateral movement across your network. Identify where your hybrid network is exposed to public networks In complex network setups with multi-cloud and hybrid systems, it is very important to see everything that is happening. You need to know how your business apps connect, including any vectors that unwanted or harmful traffic, such as bots, could use. To understand where your hybrid network is exposed to public networks, you need a complete map of your network and the ability to simulate traffic. This information can help you find and fix points where your network is exposed. Respond to incidents coming from SIEM/SOAR solutions with rapid isolation SIEM/SOAR systems collect and examine logs from your IT setup, security tools, and business apps. This helps the SOC team find and flag strange activities for further investigation. But with so much data, many alerts are false positives. Still, this does not mean you are lost in a sea of noise. By linking security incidents to network traffic patterns, you can tell if a compromised server is exposed to the internet. This can help you quickly separate an infected server if a Trojan gets past your defenses, which is a crucial strategy in stopping ransomware attacks. Schedule a Demo What steps must you take when a ransomware attack is detected? Step 1: Identify the attack – Act quickly if you think you are under a ransomware attack. Signs of an attack can include files you cannot open, weird computer activity, or a ransom message on your screen. If you see these, confirm it is ransomware and take steps to limit the damage. Step 2: Isolate affected systems – When you know you are under attack, isolate the affected computers from the rest of your network. This can stop the ransomware from spreading. You might need to disconnect from the internet, turn off Wi-Fi, or even shut down the system. Step 3: Secure backup data – Backups can help you recover from ransomware. If you have not already saved backups in a different place or offline, do it immediately to protect data from damage. Step 4: Report the incident – Tell your IT department or security team about the attack. If you do not have an IT team, you might need help from a cybersecurity company. Also, tell the law enforcement agencies and any organizations you are a part of that might need to know. Step 5: Preserve evidence – Keep any evidence related to the ransomware attack. This might include ransom messages, emails, or system logs. This evidence can help the police and cybersecurity experts understand what happened and might help get your data back. Step 6: Remove the ransomware – IT or cybersecurity experts should be the ones to get rid of the ransomware. They have special tools and methods to remove ransomware. Experts will ensure that it does not cause more harm to your files or computers. Step 7: Restore your systems – After the ransomware is gone, you can start fixing your systems. If you had backups that were not affected by the attack, you might be able to restore your systems to their previous state. If not, you might need a professional service to recover your data. Step 8: Post-incident review – Review what happened and how you responded. Find any weak spots in your security that the attack exploited and make a plan to improve your safety. This step can help stop future attacks and strengthen your business’s cybersecurity. Schedule a Demo How does AlgoSec prevent and mitigate ransomware attacks?

success stories "AlgoSec’s Security Management Solution is incredibly powerful. Its intelligent process improvements have directly translated into the highest level of security and compliance for our customers’ networks" Background With over 45 years’ experience in the banking sector, Atruvia ( formerly Fiducia IT AG) is one of the top ten IT providers in Germany. Today, Atruvia manages the IT networks of nearly 1,100 banks, constituting more than 100,000 PC workstations, 6,600 servers and 25,000 self-service banking terminals. Responsible for ensuring the smooth and secure processing of more than 16 billion transactions per year for its customers, Atruvia’s risk mitigation and regulatory compliance strategies are of utmost importance. Challenge To protect its customer networks, Atruvia implemented a number of security solutions, including 60 Check Point and 20 Juniper firewall clusters. However, managing multiple firewalls in a multi-vendor environment proved challenging. “Performing vulnerability assessments for such a large and complex firewall environment was extremely time-consuming, labor-intensive and prone to human error,” says Lutz Bleyer, Atruvia’s Chief Information Security Officer. With multiple stakeholders at each of its client organizations, Atruvia required a structured change management process to prevent firewall policies from growing unmanageable and creating security risks. “We needed a proven firewall management and workflow solution to eliminate potential security risks while providing us with complete visibility into our customer networks, anytime, anywhere,” says Bleyer. Solution After an in-depth analysis, Atruvia chose the AlgoSec Security Management Solution to optimize its security, compliance and change management processes. “AlgoSec provided the most comprehensive, intelligent automation solution for our firewall operations, helping us increase efficiency while improving risk mitigation and compliance,” says Bleyer. Results AlgoSec’s topology-aware technology provides Atruvia with complete visibility into the security landscape of its customers’ networks. “AlgoSec’s in-depth visibility enables us to easily create a hierarchy profile and establish a competency baseline of operations for each networks’ firewalls, even when multiple vendor technologies are involved,” says Bleyer. Atruvia’s security consultants and auditors are now closely aligned with their customers’ IT teams, regardless of their location. “The level of visibility AlgoSec provides across our customers’ security networks, and the ability to perform coordinated tasks remotely with them, enables us to work hand-in-hand as a joint team,” says Bleyer. Atruvia also uses AlgoSec to automate policy change management across customers’ firewall environments, enabling the company to eliminate manual and inefficient processes associated with the security policy change lifecycle, save time and reduce the potential for human error. “AlgoSec has fundamentally changed how we manage sophisticated, multi-device, multi-vendor firewall environments. By automating our workflows, we’ve eliminated unnecessary policy changes and reduced the time required to process changes by half,” explains Bleyer. “Thanks to AlgoSec’s intelligent automation, we’ve gained valuable optimization capabilities enabling our teams to operate smarter and faster.” Another important AlgoSec feature is its automatic assessment and reporting capabilities, which help Atruvia ensure that it remains in continuous compliance with corporate governance rules and adheres to regulatory standards, including ISO 27001, ISO 27002 and Sarbanes-Oxley (SOX).

Microsegmentation Zero Trust: How Microsegmentation Drives Zero Trust Success Microsegmentation zero trust is the practice of enforcing zero trust principles through fine‑grained, application‑aware segmentation at the workload and service level. Companies today are turning to microsegmentation, a granular form of network segmentation, to contain attacks quickly, prove least‑privilege access, and simplify compliance across hybrid environments. Despite still having to spend an average of $4.4 million per breach, according to IBM's Cost of a Data Breach Report 2025 , this is 9% lower than 2024. That drop ties directly to faster identification and containment—outcomes microsegmentation accelerates by limiting lateral movement and shrinking the blast radius from the first indicator of compromise. In yet another study, Verizon’s 2025 Data Breach Investigations Report , more than 12,000 confirmed breaches demonstrated how multi-stage intrusions use lateral movement, which microsegmentation technology directly addresses. Meanwhile, the Payment Card Industry Data Security Standard (PCI DSS) requires network segmentation for system scope reduction, which leads to decreased audit work and better system isolation. Taken together, these findings underscore a simple point: Organizations need application‑aware controls—specifically microsegmentation—to stop attackers from moving between systems and to operationalize zero trust. This article discusses the zero trust vs. micro‑segmentation debate, explains how zero trust and microsegmentation in fact work together, and provides a path to design, enforce, and operate this approach. What Is Microsegmentation? Microsegmentation divides networks into small, secure domains that match workload requirements and user/service identities with explicit allow‑rules to stop lateral movement. Network security today benefits from application-based boundaries, i.e., policies applied where applications actually communicate—not just subnets and VLANS. In practice, that means protecting individual workloads and the communication between them across data centers, public clouds, containers, and endpoints—rather than vaguely “protecting components” or “locations.” What Is the Difference Between Traditional (Macro) and Micro-Segmentation This comparison comes down to a difference in approach: Macro-segmentation uses broad VLANs and subnets or DMZs to divide network tiers; while this provides limited east-west control, it is simpler to design. Micro-segmentation uses SDN and host agents, as well as cloud security groups; application-specific policies are enforced at the workload/service boundary, which is why they are the engine of microsegmentation zero trust. What Role Do Firewalls and Network Segmentation Layers Play in Microsegmentation? Your existing perimeter and internal firewalls provide north‑south control, compliance zones, and enforcement points that microsegmentation can orchestrate. In other words, microsegmentation complements firewalls and network segmentation layers—it does not replace them. Extending the point above: Microsegmentation orchestrates those firewall and segmentation layers to deploy least‑privilege across hybrid systems—specifically: Cloud security groups NACLs SDN fabrics Kubernetes policies Host-based controls Since these layers are complementary, they collectively shrink the blast radius. What Is Zero Trust? Zero trust is a security concept, not a product or service. The system uses identity-based dynamic authorization, which takes into account device health status and environmental context—instead of traditional static location-based access methods. Verification is continuous because environments and risk conditions evolve. Zero trust verifies every access decision—no implicit trust—and enforces least privilege Zero Trust vs. Micro‑Segmentation: Complementary Forces While zero trust operates as an operational framework, microsegmentation functions as an implementation methodology. While zero trust explains what needs protection and which aspects require protection, microsegmentation provides the how. The table below breaks down the two concepts across key parameters. Aspect Zero Trust (Strategy) Microsegmentation (Mechanism) Focus Identity, posture, continuous verification Allowed app/workload flows Scope Enterprise‑wide architecture App tiers, services, identities Enforcement Policies derived from context and risk SDN, host agents, security groups, firewalls Outcome Minimized implicit trust; provable least‑privilege Contained blast radius; fewer lateral‑movement paths What Is Microsegmentation Zero Trust? The combination of zero trust and microsegmentation forms microsegmentation zero trust—a strategy connected to enforcement. The three primary goals of this approach are: Risk reduction Lateral movement prevention Least privilege verification Microsegmentation zero trust applies zero trust principles—continuous verification and least privilege—by defining and enforcing explicit, application‑aware allow‑rules between identities, services, and workloads. Why Does Microsegmentation Zero Trust Matter? It matters because it measurably reduces lateral movement paths and speeds incident containment. Authorized paths are explicitly permitted communication flows (service A to service B on port X from an approved identity) that have been validated as necessary for the application to function. Pre‑defining and testing these authorized paths speeds deployment because changes ship with pre-validated, least‑privilege policies—reducing last‑minute firewall rework, minimizing approvals, and preventing rollback from unexpected blocks. Implementing Microsegmentation to Achieve Zero Trust Microsegmentation is a continuous process, consisting of multiple stages to successfully achieve zero trust. Asset & Dependency Discovery Start by analyzing the network traffic behavior of applications and workloads in traditional on-premises setups, public clouds, and container environments. This application-first view serves as the base for zero trust segmentation, which stops security gaps from occurring. Policy Creation Create allow‑lists for individual app components and identity groups based on observed application traffic flows (sources/destinations, ports, processes) and documented business requirements, then validate with “what‑if” simulations before production. Enforcement Implement the approved policy through current controls—cloud security groups, firewalls, SDN fabrics, host controls, and Kubernetes—to achieve uniform protection across hybrid and multi-cloud systems. Continuous Monitoring & Adaptive Policy Continuously monitor for drift, prune unused rules, and adjust policies using detection data—without re‑introducing broad implicit trust or “allow any” access. Challenges & Pitfalls to Avoid Security organizations that operate effectively still encounter various obstacles when implementing microsegmentation: Lack of visibility in application maps: When third-party or SaaS endpoints and ephemeral services (containers, serverless functions) are not properly documented, visibility suffers. The fix? Run continuous dependency discovery operations while keeping tags and labels up to date. Focusing solely on network-based controls: Ignoring workload and identity context can weaken your security measures. The fix? Use service accounts, workload identities, namespaces, and labels as the basis for policy connections whenever possible. Relying on a single technology: Depending only on firewalls or security groups can create gaps in your security posture. The fix? Implement security orchestration using a combination of firewalls, SDN security groups, and Kubernetes network policies. Manual exception handling: Human intervention creates delays, slowing down release cycles. The fix? Orchestrate a combination of controls—next‑gen firewalls, SDN fabrics, cloud security groups, and Kubernetes network policy—so each layer covers the others.
