Learn from expert-crafted firewall ruleset examples and best practices. Optimize your security posture with actionable guidance and improve your firewall configurations. Firewall ruleset examples & policy best practices Securing your network: guide to firewall rules examples Cyberattacks continue to rise globally as malicious actors tirelessly develop sophisticated tools and techniques to break through networks and security systems. With the digitalization of operations today and the increasing adoption of remote working, crucial business activities such as communication, data storage, and data transmission are now primarily done digitally. While this brings numerous advantages – allowing easy usability and scalability, enhancing collaboration, and reducing the risks of data loss – businesses have to deal with various security risks, such as data breaches and cyberattacks from hackers. Organizations must provide adequate network security to keep sensitive data safe and ensure their network is usable, trustworthy, and optimized for maximum productivity across all channels. Schedule a Demo Firewalls and your network Your network and systems (software and hardware) comprise the IT infrastructure through which you operate and manage your enterprise’s IT services. Every IT system regularly receives and transmits internet traffic, and businesses must ensure that only trusted and authorized traffic penetrates their network to maintain security. All unwanted traffic must be prevented from accessing your operating system as it poses a huge risk to network security. Malicious actors attempting to penetrate your system often send virus-carrying inbound traffic to your network. However, with an effective firewall, you can filter all traffic and block unwanted and harmful traffic from penetrating your network. A firewall serves as a barrier between computers, networks, and other systems in your IT landscape, preventing unauthorized traffic from penetrating. Schedule a Demo What are firewall rules? The firewall is your first line of defense in network security against hackers, malware, and other threats. Firewall rules refer to access control mechanisms that stipulate how a firewall device should handle incoming and outgoing traffic in your network. They are instructions given to firewalls to help them know when to block or allow communication in your network. These instructions include destination or source IP addresses, protocols, port numbers, and services. A firewall ruleset is formed from a set of rules and it defines a unit of execution and sharing for the rules. Firewall rulesets typically include: A source address A source port A destination address A destination port A decision on whether to block or permit network traffic meeting those address and port criteria Schedule a Demo What are the most common firewall ruleset examples? There are thousands of rulesets that can be used to control how a firewall deals with network traffic. Some firewall rules are more common than others, as they tend to be fundamental when building a secure network. Here are some examples of firewall rules for common use cases: Enable internet access for only one computer in the local network and block access for all others This rule gives only one computer in the local network access to the internet, and blocks all others from accessing the internet. This example requires obtaining the IP address of the computer being granted access (i.e., source IP address) and the TCP protocol type. Two rules will be created: a Permit rule and a Deny rule. The permit rule allows the chosen computer the required access, while the deny rule blocks all other computers in the local network from internet access. Prevent direct access from the public network to the firewall This rule blocks access to your firewall from any public network, to protect it from hackers who can modify or delete your rules if they access your firewall directly. Once hackers manipulate your rules, unwanted traffic will penetrate your network, leading to data breaches or an interruption in operation. A Deny rule for any attempt to access the firewall from public networks will be created and enabled. Block internet access for only one computer in the local network This rule comes in handy if you do not want a specific computer in the local network to access the internet. You will need to create a Deny rule in which you set the IP address of the computer you wish to block from the internet, and the TCP protocol type. Block access to a specific website from a local network In this scenario we want to configure our firewall to deny access to a particular website from a local network. We first obtain the IP address or addresses of the website we wish to deny access to, and then create a Deny rule. One way to obtain a website’s IP address is by running the special command ‘nslookup ’ in your operating system’s command line (Windows, Linux, or others). Since websites can run on HTTP and HTTPS, we must create a Deny rule for each protocol type and indicate the destination IP address(es). Thus, the local network will be unable to access both the HTTP and HTTPS versions of the website. Allow a particular LAN computer to access only one specific website This example gives a local computer access to only one specified website. We obtain the IP address of the destination website and the source IP address (of the local computer). We create a Permit rule for the source IP address and the destination website, and a Deny rule for the source IP address and other websites, taking the TCP protocol types into account. Allow internet access to and from the local network using specific protocols (services) only This example allows your LAN computer to access the internet using specific protocols, such as SMTP, FTP, IPv6, SSH, IPv4, POP3, DNS, and IMAP; and blocks all other traffic Here we first create an “Allow” rule for the “Home segment,” where we use the value “Any” for the Source and Destination IP addresses. In the Protocol field provided, we choose the protocols through which our local computer can access the internet. Lastly, we create Deny rules where we enter the value “Any” for the Source and Destination IP addresses. In the Protocol field, we set the values TCP and UDP, thus blocking internet access for unspecified protocols. Allow remote control of your router This rule enables you to access, view, or change your Router Settings remotely (over the internet). Typically, access to routers from the internet is blocked by default. To set this rule, you need specific data such as your router username, WAN IP address, and password. It is crucial to note that this setting is unsafe for individuals who use public IP addresses. A similar use case is a rule enabling users to check a device’s availability on their network by allowing ICMP ping requests. Block access from a defined internet subnet or an external network You can set a rule that blocks access to your network from a defined internet subnet or an external network. This rule is especially important if you observed repeated attempts to access your router from unknown IP addresses within the same subnet. In this case, set a Deny rule for IP addresses of the subnet attempting to access your WAN port. Schedule a Demo What are examples of best practices for setting up firewall rules? It is expedient to follow best practices during firewall configuration to protect your network from intruders and hackers. Deploying industry-standard rules when setting up firewalls can improve the security of your network and system components. Below are examples of the best practices for setting up firewall rules. Document firewall rules across multiple devices Documenting all firewall rule configurations and updating them frequently across various devices is one of the best practices for staying ahead of attacks. New rules should be included based on security needs, and irrelevant rules should be deactivated to reduce the possibility of a loophole in your network. With documentation, administrators can review the rules frequently and make any required changes whenever a vulnerability is detected. Configure your firewall to block traffic by default Using a block or deny-by-default policy is the safest way to deal with suspicious traffic. Enterprises must be sure that all types of traffic entering their network are identified and trusted to avoid security threats. In addition, whenever a vulnerability arises in the system, blocking by default helps prevent hackers from taking advantage of loopholes before administrators can respond. Monitor firewall logs Monitoring firewall logs on a regular basis helps maintain network security. Administrators can quickly and easily track traffic flow across your network, identify suspicious activity, and implement effective solutions in a timely manner. Organizations with highly sophisticated infrastructure can aggregate logs from routers, servers, switches, and other components to a centralized platform for monitoring. Group firewall rules to minimize complexity and enhance performance Depending on the complexity of your network, you may need thousands of rules to achieve effective network security. This complicates your firewall rules and can be a huge challenge for administrators. However, by grouping rules based on similar characteristics like protocols, TCP ports, IP addresses, etc., you simplify them and boost overall performance. Implement least-privileged access In any organization, employees have various roles and may require different data to execute their tasks efficiently. As part of network security practices, it’s important to ensure each employee’s access to the network is restricted to the minimum privileges needed to execute their tasks. Only users who require access to a particular service or resource should have it, thus preventing unnecessary exposure of data. This practice significantly minimizes the risk of intentional and accidental unauthorized access to sensitive data. Schedule a Demo How do firewall policies differ from a network security policy? A network security policy outlines the overall rules, principles, and procedures for maintaining security on a computer network. The policy sets out the basic architecture of an organization’s network security environment, including details of how the security policies are implemented. The overall objective of network security policy is to protect a computer network against internal and external threats. Firewall policies are a sub-group of network security policies, and refer to policies that relate specifically to firewalls. Firewall policies have to do with rules for how firewalls should handle inbound and outbound traffic to ensure that malicious actors do not penetrate the network. A firewall policy determines the types of traffic that should flow through your network based on your organization’s network and information security policies. Schedule a Demo How can AlgoSec help with managing your firewall rules? Proper firewall configuration with effective rules and practices is crucial to building a formidable network security policy. Organizations must follow industry standards in configuring firewall rules and protecting their IT landscape from intruders and malicious actors.

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 4/16/21 Published Tsippi Dach, Director of Communications at AlgoSec, explores the relationship between NetOps and SecOps and explains why they are the perfect partnership The IT landscape has changed beyond recognition in the past decade or so. The vast majority of businesses now operate largely in the cloud, which has had a notable impact on their agility and productivity. A recent survey of 1,900 IT and security professionals found that 41 percent or organizations are running more of their workloads in public clouds compared to just one-quarter in 2019. Even businesses that were not digitally mature enough to take full advantage of the cloud will have dramatically altered their strategies in order to support remote working at scale during the COVID-19 pandemic. However, with cloud innovation so high up the boardroom agenda, security is often left lagging behind, creating a vulnerability gap that businesses can little afford in the current heightened risk landscape. The same survey found the leading concern about cloud adoption was network security (58%). Managing organizations’ networks and their security should go hand-in-hand, but, as reflected in the survey, there’s no clear ownership of public cloud security. Responsibility is scattered across SecOps, NOCs and DevOps, and they don’t collaborate in a way that aligns with business interests. We know through experience that this siloed approach hurts security, so what should businesses do about it? How can they bridge the gap between NetOps and SecOps to keep their network assets secure and prevent missteps? Building a case for NetSecOps Today’s digital infrastructure demands the collaboration, perhaps even the convergence, of NetOps and SecOps in order to achieve maximum security and productivity. While the majority of businesses do have open communication channels between the two departments, there is still a large proportion of network and security teams working in isolation. This creates unnecessary friction, which can be problematic for service-based businesses that are trying to deliver the best possible end-user experience. The reality is that NetOps and SecOps share several commonalities. They are both responsible for critical aspects of a business and have to navigate constantly evolving environments, often under extremely restrictive conditions. Agility is particularly important for security teams in order for them to keep pace with emerging technologies, yet deployments are often stalled or abandoned at the implementation phase due to misconfigurations or poor execution. As enterprises continue to deploy software-defined networks and public cloud architecture, security has become even more important to the network team, which is why this convergence needs to happen sooner rather than later. We somehow need to insert the network security element into the NetOps pipeline and seamlessly make it just another step in the process. If we had a way to automatically check whether network connectivity is already enabled as part of the pre-delivery testing phase, that could, at least, save us the heartache of deploying something that will not work. Thankfully, there are tools available that can bring SecOps and NetOps closer together, such as Cisco ACI , Cisco Secure Workload and AlgoSec Security Management Solution . Cisco ACI, for instance, is a tightly coupled policy-driven solution that integrates software and hardware, allowing for greater application agility and data center automation. Cisco Secure Workload (previously known as Tetration), is a micro-segmentation and cloud workload protection platform that offers multi-cloud security based on a zero-trust model. When combined with AlgoSec, Cisco Secure Workload is able to map existing application connectivity and automatically generate and deploy security policies on different network security devices, such as ACI contract, firewalls, routers and cloud security groups. So, while Cisco Secure Workload takes care of enforcing security at each and every endpoint, AlgoSec handles network management. This is NetOps and SecOps convergence in action, allowing for 360-degree oversight of network and security controls for threat detection across entire hybrid and multi-vendor frameworks. While the utopian harmony of NetOps and SecOps may be some way off, using existing tools, processes and platforms to bridge the divide between the two departments can mitigate the ‘silo effect’ resulting in stronger, safer and more resilient operations. We recently hosted a webinar with Doug Hurd from Cisco and Henrik Skovfoged from Conscia discussing how you can bring NetOps and SecOps teams together with Cisco and AlgoSec.

Application Connectivity Management The great Fastly outage 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 9/29/21 Published Tsippi Dach, Director of Communications at AlgoSec, explores what happened during this past summer’s Fastly outage, and explores how your business can protect itself in the future. The odds are that before June 8th you probably hadn’t heard of Fastly unless you were a customer. It was only when swathes of the internet went down with the 503: Service Unavailable error message that the edge cloud provider started to make headlines . For almost an hour, sites like Amazon and eBay were inaccessible, costing millions of dollars’ worth of revenue. PayPal, which processed roughly $106 million worth of transactions per hour throughout 2020, was also impacted, and disruption at Shopify left thousands of online retail businesses unable to serve customers. While the true cost of losing a significant portion of the internet for almost one hour is yet to be tallied, we do know what caused it. What is Fastly and why did it break the internet? Fastly is a US-based content distribution network (CDN), sometimes referred to as an ‘edge cloud provider.’ CDNs relieve the load on a website’s servers and ostensibly improve performance for end-users by caching copies of web pages on a distributed network of servers that are geographically closer to them. The downside is that when a CDN goes down – due to a configuration error in Fastly’s case – it reveals just how vulnerable businesses are to forces outside of their control. Many websites, perhaps even yours, are heavily dependent on a handful of cloud-based providers. When these providers experience difficulties, the consequences for your business are amplified ten-fold. Not only do you run the risk of long-term and costly disruption, but these weak links can also provide a golden opportunity for bad actors to target your business with malicious software that can move laterally across your network and cause untold damage. How micro-segmentation can help The security and operational risks caused by these outages can be easily mitigated by implementing plans that should already be part of an organization’s cyber resilience strategy. One aspect of this is micro-segmentation , which is regarded as one of the most effective methods to limit the damage of an intrusion or attack and therefore limit large-scale downtime from configuration misfires and cyberattacks. Micro-segmentation is the act of creating secure “zones” in data centers and cloud deployments that allow your company to isolate workloads from one another. In effect, this makes your network security more compartmentalized, so that if a bad actor takes advantage of an outage in order to breach your organization’s network, or user error causes a system malfunction, you can isolate the incident and prevent lateral impact. Simplifying micro-segmentation with AlgoSec Security Management Suite The AlgoSec Security Management Suite employs the power of automation to make it easy for businesses to define and enforce their micro-segmentation strategy, ensuring that it does not block critical business services, and also meets compliance requirements. AlgoSec supports micro-segmentation by: Mapping the applications and traffic flows across your hybrid network Identifying unprotected network flows that do not cross any firewall and are not filtered for an application Automatically identifying changes that will violate the micro-segmentation strategy Ensuring easy management of network security policies across your hybrid network Automatically implementing network security policy changes Automatically validating changes Generating a custom report on compliance with the micro-segmentation policy Find out more about how micro-segmentation can help you boost your security posture, or request your personal demo .

The Cloud's Underbelly: Where the Dangers Hide The cloud has revolutionized business, but it's also opened up a whole new can of security worms. It's like building a magnificent castle in the sky, but forgetting to install the drawbridge and moat. Here's the deal: the faster you embrace the cloud, the harder it gets to keep an eye on everything. Think sprawling cloud environments with hidden corners and shadowy figures lurking in the depths. If you can't see what's going on, you're practically inviting those cyber-bandits to steal your precious data and leave you with a hefty ransom note. In this post, we're shining a light on those hidden dangers and giving you the tools to take back control of your cloud security. Get ready to become a cloud security ninja! Cloud Security Challenges: A Rogue's Gallery Cloud security is like a tangled web – complex, ever-changing, and full of surprises. Let's break down the top five reasons why securing your cloud can feel like a Herculean task. 1. Cloud Adoption on Steroids: Think of cloud adoption as a rocket launch – it's not a one-time event, but a continuous journey into the unknown. New resources are constantly being added, applications are migrating, and data is flowing like a raging river. Keeping track of everything and ensuring its security is like trying to herd cats in a hurricane. And hold on tight, because Gartner predicts that by 2027, global public cloud spending will blast past the $1 trillion mark! That's a whole lot of cloud to manage and secure. 2. Security's Unique Demands: The cloud's a shape-shifter, constantly changing and evolving. That means your attack surface is never static – it's more like a wriggling octopus with tentacles reaching everywhere. And if you're not careful, those tentacles can be riddled with vulnerabilities and misconfigurations, just waiting for a cyber-pirate to exploit them. Legacy security solutions? They're like trying to fight a dragon with a water pistol. They simply can't keep up with the cloud's dynamic nature, leaving you vulnerable to breaches, compliance failures, and a whole lot of financial pain. Figure 1: Gartner’s Top Cybersecurity Trends for 2024 (Source: Gartner ) 3. The Threat Landscape: A Cyber-Jungle The cyber threat landscape is a dangerous jungle, and your cloud environment is the prized watering hole. McKinsey estimates that by 2025, cyberattacks will cost businesses a staggering $10.5 trillion annually! That's enough to make even the bravest cloud warrior tremble. And as if the cloud's inherent challenges weren't enough, you've got a relentless horde of cyber-criminals trying to breach your defenses. Just look at some of the major attacks in 2024: AT&T : 110 million customer phone records compromised – that's like losing a phone book the size of a small city! Ticketmaster : 560 million customer records stolen – a hacking collective hit the jackpot with this one! Dell : 49 million customers' data compromised through brute-force attacks – talk about a battering ram! Figure 2: Stolen Ticketmaster data on illicit marketplaces (Source: Bleeping Computer ) 4. Regulatory Pressures: The Compliance Gauntlet Navigating the world of compliance is like running a gauntlet – one wrong step and you'll get hit with a penalty. Without a crystal-clear view of your cloud resources, networks, applications, and data, you're practically walking blindfolded through a minefield. Poor visibility, suboptimal network segmentation, and inconsistent rules are the enemies of compliance. They're like cracks in your cloud fortress, just waiting for an auditor to exploit them.

Reputation on the Line: In today's cutthroat business world, your cloud expertise is your reputation. One major security disaster can send your customers running for the hills and leave your brand in tatters. Securing Your Cloud Kingdom: A Battle Plan So, how do you defend your cloud kingdom from these relentless threats? It's time to ditch those outdated security solutions and embrace a multi-layered, application-centric approach. Think of it as building a fortress with multiple walls, guard towers, and a crack team of archers ready to defend your precious assets. Here's your battle plan: Trim the Fat: Keep your attack surface lean and mean by constantly pruning unnecessary resources and applications. It's like trimming the hedges around your castle to eliminate hiding spots for those pesky intruders. Map Your Terrain: Get a bird's-eye view of your entire cloud landscape – public, private, hybrid, the whole shebang! Understand how everything connects and interacts, so you can identify and prioritize risks like a true cloud strategist. Banish Shadow IT: Don't let those rogue employees sneak in unauthorized applications and resources. Shine a light on shadow IT and bring it under your control before it becomes a backdoor for attackers. Protect Your Treasure: Exposed data is like leaving your crown jewels out in the open. Identify and secure your sensitive data with an iron grip. Hunt for Weaknesses: Continuously scan your cloud environment for vulnerabilities and misconfigurations. Even the smallest crack can be exploited by a determined attacker. Prioritize and address those weaknesses before they turn into a breach. Conquer Compliance: Compliance can be a beast, but it's a beast you can tame. Design and implement security policies and configurations that meet those regulatory demands. Remember, a secure cloud is a compliant cloud. Fortify Your Policies: Strong security policies are the guardians of your cloud kingdom.

Explore Algosec's customer success stories to see how organizations worldwide improve security, compliance, and efficiency with our solutions. Discovery Streamlines Firewall Audits And Simplifies The Change Workflow Organization Discovery Industry Financial Services Headquarters Johannesberg, South Africa Download case study Share Customer
success stories "With AlgoSec we can now get, in a click of a button, what took two to three weeks per firewall to produce manually" Background Discovery Limited is a South African-founded financial services organization that operates in the healthcare, life assurance, short-term insurance, savings and investment products and wellness markets. Founded in 1992, Discovery was guided by a clear core purpose — to make people healthier and to enhance and protect their lives. Underpinning this core purpose is the belief that through innovation, Discovery can be a powerful market disruptor. The company, with headquarters in Johannesburg, South Africa, has expanded its operations globally and currently serves over 4.4 million clients across South Africa, the United Kingdom, the United States, China, Singapore and Australia.Operating in the highly regulated insurance and health sectors, Discovery monitors its compliance with international privacy laws and security criteria, includingPCI-DSS globally, Sarbanes-Oxley and HIPAA in the US, the Data Protection Act in the UK, and South Africa’s Protection of Personal Information Act. Challenge During its early years, the company managed its firewalls through an internally developed, legacy system which offered very limited visibility into the change request process.“We grew faster than anyone expected,” says Marc Silver, Security Manager at Discovery. “We needed better visibility into what changes were requested to which firewall, for what business need and also to ensure proper risk analysis.”Discovery’s growth necessitated a rapid increase in the number of firewalls deployed, and the corresponding ruleset sizes. The time required to audit them grew by orders of magnitude, ultimately taking up to three weeks per firewall. The IT Security team of four engineers recognized that it needed a fresh approach to manage risk and ensure compliance. Solution Discovery chose the AlgoSec Security Management Solution to deliver automated, comprehensive firewall operations, risk analysis and change management. Silver states that compared to AlgoSec’s competitors, “AlgoSec has a more tightly integrated change control, and is easier to manage. Another big advantage is how it finds unused rules and recommends rule consolidations,” says Silver.AlgoSec’s integration with Request Tracker (RT) change management system was also important in Discovery’s selection of a security management solution. “We use RT for our internal ticketing system, and the stability of AlgoSec’s integration with RT met our requirements. AlgoSec’s visual workflow is clear, easy to understand and more mature than the others we evaluated,” adds Silver. Results Since implementing AlgoSec, Discovery has found its security audits running more effectively. Discovery relies on AlgoSec’s built-in compliance reports to address Sarbanes-Oxley, HIPAA, PCI-DSS, and other national and international regulatory requirements. “Every year internal auditors would take our entire rulesets for each firewall pair and tell us where we needed to make improvements. AlgoSec now allows us to submit an automated report to our auditing team. It tells them what our security state is, and what needs to be remediated. The total process used to take three months. Now, in a click of a button, we can get what took two to three weeks per firewall to produce manually,” says Silver.Discovery has also found an unexpected advantage: “AlgoSec tells us what rules are in use and what rules are not. For one firewall, we were able to remove 30,000 rules. A firewall with 500,000 rules isn’t going to cope as well as one with 100,000 rules. By optimizing our devices, AlgoSec saves us money in the long term by enabling us to delay upgrading to a larger firewall,” adds Silver.In conclusion, Silver states that “Now we can see what is and isn’t happening in our security system. It has made a much bigger impact than we thought it would. With AlgoSec’s policy optimization, and the time we save on compliance, AlgoSec has given us a much stronger competitive edge than we had six months ago.” Schedule time with one of our experts

Zero trust vs micro segmentation Select a size Which network Can AlgoSec be used for continuous compliance monitoring? Yes, AlgoSec supports continuous compliance monitoring. As organizations adapt their security policies to meet emerging threats and address new vulnerabilities, they must constantly verify these changes against the compliance frameworks they subscribe to. AlgoSec can generate risk assessment reports and conduct internal audits on-demand, allowing compliance officers to monitor compliance performance in real-time. Security professionals can also use AlgoSec to preview and simulate proposed changes to the organization’s security policies. This gives compliance officers a valuable degree of lead-time before planned changes impact regulatory guidelines and allows for continuous real-time monitoring. 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.

Cloud Security Hijacked NPM Account Leads to Critical Supply Chain Compromise 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 10/24/21 Published As earlier reported by US-CERT, three versions of a popular NPM package named ua-parser-js were found to contain malware. The NPM package ua-parser-js is used in apps and websites to discover the type of device or browser a person is using from User-Agent data. The author of the package, Faisal Salman – a software developer from Indonesia, has commented about the incident: Hi all, very sorry about this. I noticed something unusual when my email was suddenly flooded by spams from hundreds of websites (maybe so I don’t realize something was up, luckily the effect is quite the contrary). I believe someone was hijacking my npm account and published some compromised packages (0.7.29, 0.8.0, 1.0.0) which will probably install malware as can be seen from the diff here: https://app.renovatebot.com/package-diff?name=ua-parser-js&from=0.7.28&to=1.0.0 I have sent a message to NPM support since I can’t seem to unpublish the compromised versions (maybe due to npm policy https://docs.npmjs.com/policies/unpublish ) so I can only deprecate them with a warning message. There are more than 2.5 million other repositories that depend on ua-parser-js . Google search “file:ua-parser-js.js” reveals nearly 2 million websites, which indicates the package is popular. As seen in the source code diff , the newly added file package/preinstall.js will check the OS platform. If it’s Windows, the script will spawn a newly added preinstall.bat script. If the OS is Linux, the script will call terminalLinux() function, as seen in the source below: var opsys = process.platform; if ( opsys == "darwin" ) { opsys = "MacOS" ; } else if ( opsys == "win32" || opsys == "win64" ) { opsys = "Windows" ; const { spawn } = require ( 'child_process' ) ; const bat = spawn ( 'cmd.exe' , [ '/c' , 'preinstall.bat' ]) ; } else if ( opsys == "linux" ) { opsys = "Linux" ; terminalLinux () ; } The terminalLinux() function will run the newly added preinstall.sh script. function terminalLinux(){ exec( "/bin/bash preinstall.sh" , (error, stdout, stderr) => { ... }); } The malicious preinstall.sh script first queries an XML file that will report the current user’s geo-location by visiting this URL . For example, for a user located in Australia, the returned content will be: [IP_ADDRESS] AU Australia ... Next, the script searches for the presence of the following country codes in the returned XML file: RU UA BY KZ That is, the script identifies if the affected user is located in Russia, Ukraine, Belarus, or Kazakhstan. Suppose the user is NOT located in any of these countries. In that case, the script will then fetch and execute malicious ELF binary jsextension from a server with IP address 159.148.186.228, located in Latvia. jsextension binary is an XMRig cryptominer with reasonably good coverage by other AV products. Conclusion The compromised ua-parser-js is a showcase of a typical supply chain attack. Last year, Prevasio found and reported a malicious package flatmap-stream in 1,482 Docker container images hosted in Docker Hub with a combined download count of 95M. The most significant contributor was the trojanized official container image of Eclipse. What’s fascinating in this case, however, is the effectiveness of the malicious code proliferation. It only takes one software developer to ignore a simple trick that reliably prevents these things from happening. The name of this trick is two-factor authentication (2FA). About the Country Codes Some people wonder why cybercriminals from Russia often avoid attacking victims outside of their country or other Russian-speaking countries. Some go as far as suggesting it’s for their own legal protection. The reality is way simpler, of course: “Не гадь там, где живешь” “Не сри там, где ешь” “Не плюй в колодец, пригодится воды напиться” Polite translation of all these sayings is: “One should not cause trouble in a place, group, or situation where one regularly finds oneself.” Schedule a demo Related Articles Q1 at AlgoSec: What innovations and milestones defined our start to 2026?
