Explore micro-segmentation: a powerful security strategy. Discover real-world examples, top solutions, and key benefits for enhanced security and reduced risk. Micro-segmentation: Examples, solutions & top benefits Micro-segmentation: What it is, how it works, benefits Micro-segmentation means breaking down enterprise networks into multiple segments and using security policies to dictate how the data and applications in each segment will be accessed. These determinations are made by limiting traffic based on zero trust and least privilege principles. It provides a viable solution to flawed network security policies that weaken enterprise security. A micro-segmentation strategy enables organizations to reduce the size of their attack surface and make their networks safer against potential breaches. It also allows them to improve incident response, contain the impact of breaches, and maintain compliance with relevant laws and regulations. Schedule a Demo The need for micro-segmentation All organizations must protect their data centers with robust and effective firewall policies. Without these policies and associated security controls, smart and devious cybercriminals can easily hack into enterprise networks and systems. Micro-segmentation provides an effective way to install strong, clean, and easily-manageable security policies that help to create a more secure on-prem or hybrid cloud environment. This environment can keep traffic safe and block potential breaches from corrupting servers or compromising data. Moreover, creating multiple logical segments that are isolated from each other and enforced with least-privileged access keeps threat actors out of the network and also helps to contain a breach if it does happen. Schedule a Demo How micro-segmentation works Micro-segmentation can be applied in both on-prem data centers and cloud environments. It isolates network workloads which enable security teams to create security policies. These policies dictate the type of traffic passing in and out of each micro-segment. The policies are used to manage and create secure network segments and determine how these segments or zones will be accessed. They dictate how applications and workloads will access the resources they need, how they will share data within a system, and in which direction. Micro-segmentation also enables security teams to determine what kind of security or authentication measures are required for the environment. There are three main micro-segmentation approaches. Micro-segmentation works differently depending on which approach is adopted. Agent-based/host-based micro-segmentation Agent-based micro-segmentation utilizes a software agent deployed on the workload. It doesn’t rely on static network-level rules based on network ports or IP addresses. The agent allows security teams to enforce granular isolation, better control individual hosts, and implement automated segmentation policies with human-readable labels. Agent-based micro-segmentation security solutions are infrastructure-independent so they can be deployed across both data center and cloud infrastructure. One drawback of the method is that not all workloads can have an agent installed on them. Also, attackers can exploit the trust in the network with host firewall-based micro-segmentation. Network-based micro-segmentation Network-based micro-segmentation leverages the network infrastructure to enforce security policies. The policies are configured and enforced using access control lists (ACLs) or IP constructs. There’s no need to deploy agents on workloads. A drawback of this method is that the policies can only be enforced per endpoint, so network firewalls cannot distinguish between legitimate software and malware and will therefore block or allow both. Also, the policies are static, which can cause performance issues in more dynamic (e.g., cloud) environments. Finally, the approach can be complicated to manage when more granular micro-segments and a higher number of firewall rules are created. Hypervisor-based micro-segmentation This method depends on virtualized environments and hypervisors to create overlay networks and enforce micro-segmentation. The approach does not require network hardware changes. Also, its policy constructs are easy to learn for security teams. The chief drawback of the approach is that it doesn’t support bare metal servers, container workloads, or public cloud environments. Also, it doesn’t provide host-level visibility into its software, processes, vulnerabilities, etc. Schedule a Demo Examples of micro-segmentation One common example of micro-segmentation is the separation of development and testing environments from production environments. Granularly limiting the connections between these environments prevents careless or dangerous activities, such as using sensitive/live data for testing. Other examples include: Application micro-segmentation: Restricting access to sensitive data in applications to prevent unauthorized use or malicious exfiltration User micro-segmentation: Leveraging user identity services to control access to applications and services Tier-level micro-management: Separating application components to allow only authorized users to access specific components and keep unauthorized users out Schedule a Demo Network segmentation vs. Micro-segmentation Network segmentation divides the enterprise network into multiple security zones. In traditional data center environments, network segmentation is usually accomplished using firewalls, VLANs, and access control lists (ACLs). In more modern, cloud-based environments, Virtual Private Clouds (VPCs), subnets, and Security Groups (SGs). Microsoft Azure, for example, provides numerous network segmentation options, such as subscriptions (platform-powered separation between entities), virtual networks (isolated and secure networks to run virtual machines and applications), network security groups (access control mechanisms to control traffic between resources within a virtual network), and Azure firewall (a cloud-native stateful firewall-as-a-service to filter traffic flowing between cloud resources, the Internet, and on-premise). Regardless of the environment type, the zones created with network segmentation consist of multiple devices and applications. Admins can set access controls that permit only specific traffic between zones. Micro-segmentation is a more granular form of network segmentation. It involves placing each device or application within its own logically isolated segment instead of simply breaking a network into multiple, large segments. It thus provides more granular visibility and greater control than network segmentation. Unlike network segmentation which breaks the network based on north-south traffic (traffic running between clients and servers and crossing the security perimeter), micro-segmentation focuses on east-west traffic that moves laterally across and within the network. Moreover, it usually uses software policies and software-defined networking (SDN). With SDN, all network traffic is routed through an inspection point (e.g., a next-generation firewall) that can identify an attacker’s lateral movement and block inappropriate accesses to the network and its resources. Some SDN solutions, such as Cisco Application Centric Infrastructure (ACI), can automatically assign endpoints to logical security zones called endpoint groups (EPGs). These EPGs may have a contract that is used to control traffic flow between EPGs within the ACI fabric. Schedule a Demo Network segmentation challenges and how micro-segmentation Helps Dividing a network into multiple smaller segments can improve both its security and performance. Effective network segmentation allows security teams to spot an attack and act early to mitigate its impact and prevent its spread across the network. Even so, it can be challenging to implement network segmentation. For one, dividing the network into many VLANs and subnets requires a lot of manual effort. Also, the network may need to be re-architected, which can be difficult, time-consuming, and expensive. Micro-segmentation is a better and easier approach to securing a network, especially if host-based micro-segmentation is adopted. This is because the host-based approach is infrastructure-independent, provides more granular control, and enables micro-segmentation based on human-understandable policies instead of static network-level rules. Plus, the model can be deployed across both, cloud and data center environments without “coupling” to them. In addition, it decouples security policy enforcement from the physical infrastructure, simplifying administration and allowing more granular control. Also, it does not require network re-architecting so it is less time-consuming, less complex, and more cost-effective than network segmentation. Schedule a Demo Micro-segmentation: Essential for zero trust security Micro-segmentation is increasingly used to implement zero trust security . This new security model considers all users and devices untrustworthy by default. To gain access to network resources and become “trusted”, the user or device must meet the network’s conditions, for example, undergo a virus scan or complete multi-factor authentication (MFA). The zero trust model enables organizations to move away from traditional perimeter-based network security which is inadequate for modern-day remote workers and cloud environments. And micro-segmentation supports the model by: Dividing the network into smaller zones Creating a mini-perimeter around each endpoint to secure it individually Providing enhanced network visibility and stronger access controls In sum, zero trust, and micro-segmentation work in tandem by securing workloads in dynamic environments and preventing the lateral movement of unauthorized users in the network. Schedule a Demo The top 7 benefits of micro-segmentation The need for micro-segmentation is increasing because it provides all these benefits: Effective security through enhanced endpoint protection Micro-segmentation provides effective and cost-efficient security, particularly in modern network environments that are complex, dynamic, and fast-expanding. By logically dividing the data center into distinct security segments, it enables security architects to define security controls for each segment. This then reduces the size of the attack surface and enables the organization to better resist attacks or intrusions. Protection against network-based threats Micro-segmentation protects networks against network-based threats like DDoS attacks and WiFI attacks. It also allows admins to implement robust controls to restrict the flow of traffic on detecting a threat. Protection for cloud workloads and data Micro-segmentation can secure dynamic cloud systems, workloads, and data. With granular microsegments, security teams can easily monitor cloud traffic, identify suspicious or malicious traffic, and respond quickly once they detect dangerous breaches. Protection from advanced persistent threats (APTs) Individual micro-segments contain security checkpoints that help to keep cyber threats from spreading across the network. So, even if one part of a network is compromised, attackers cannot move laterally and reach or persist in other parts of the network. Thus, micro-segmentation protects the network from APTs. Improves breach containment Even if the network is breached, security staff can contain its impact with micro-segmentation. By monitoring traffic against secure policies, they can reduce the impact of a breach as well as their response time. Support for centralized policy management Organizations can use micro-segmentation to create and enforce granular security policies and to centralize policy management across networks. Without it, they would have to manually manage policies across a large fleet of devices and resources, which is a complex and time-consuming task. In addition, they can enforce zero-trust security policies, where access is allowed based on need, which can reduce the organization’s cyber risk. Endpoint separation enables regulatory compliance Micro-segmentation using the host-based approach helps isolate separately-secured endpoints, allowing security staff to easily control the traffic in systems that are subject to regulations. Policy granularity and visibility ensure that distributed devices are always protected by unified network security and also reduce the risks of non-compliant usage.

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”.

The Web application and service business loves containers, but they present a security challenge. Prevasio has the skills and experience... Cloud Security Don’t Neglect Runtime Container Security 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 9/21/20 Published The Web application and service business loves containers, but they present a security challenge. Prevasio has the skills and experience to meet the challenge. Its runtime scanning technology and techniques will let you avoid the serious risks of vulnerable or compromised containers. The very thing that makes Docker containers convenient — their all-in-one, self-contained structure — makes them opaque to traditional security tests. Instances come and go as needed, sometimes deleting themselves within seconds. This scalable and transient nature isn’t amenable to the usual tools. Prevasio’s approach is specifically designed to analyze and test containers safely, finding any problems before they turn into security incidents. The container supply chain Container images put together code from many sources. They include original source or binary code, application libraries,language support, and configuration data. The developer puts them all together and delivers the resulting image. A complex container has a long supply chain,and many things can go wrong. Each item in the image could carry a risk. The container developer could use buggy or outdated components, or it could use them improperly. The files it imports could be compromised. A Docker image isn’t a straightforward collection of files, like a gzip file. An image may be derived from another image. Extracting all its files and parameters is possible but not straightforward. Vulnerabilities and malicious actions We can divide container risks into two categories: vulnerabilities and malicious code. Vulnerabilities A vulnerability unintentionally introduces risk. An outsider can exploit them to steal information or inflict damage. In a container, they can result from poor-quality or outdated components. The building process for a complex image is hard to keep up to date. There are many ways for something to go wrong. Vulnerability scanners don’t generally work on container images. They can’t find all the components. It’s necessary to check an active container to get adequate insight. This is risky if it’s done in a production environment. Container vulnerabilities include configuration weaknesses as well as problems in code. An image that uses a weak password or unnecessarily exposes administrative functions is open to attacks. Malicious code Malware in a container is more dangerous than vulnerabilities. It could intrude at any point in the supply chain. The developer might receive a compromised version of a runtime library. A few unscrupulous developers put backdoors into code that they ship. Sometimes they add backdoors for testing purposes and forget to remove them from the finished product. The only way to catch malware in a container is by its behavior. Monitoring the network and checking the file system for suspicious changes will discover misbehaving code. The Prevasio solution Security tools designed for statically loaded code aren’t very helpful with containers. Prevasio has created a new approach that analyzes containers without making any assumptions about their safety. It loads them into a sandboxed environment where they can’t do any harm and analyzes them.The analysis includes the following: Scanning of components for known vulnerabilities Automated pen-test attacks Behavioral analysis of running code Traffic analysis to discover suspicious data packets Machine learning to identify malicious binaries The analysis categorizes an image as benign,vulnerable, exploitable, dangerous, or harmful. The administrator looks at agraph to identify any problems visually, without digging through logs. They can tell at a glance whether an image is reasonably safe to run, needs to be sent back for fixes, or should be discarded on the spot. If you look at competing container security solutions, you’ll find that the key is runtime technology. Static analysis, vulnerability scans, and signature checking won’t get you enough protection by themselves. Prevasio gives you the most complete and effective checking of container images, helping you to avoid threats to your data and your business.

Discover key insights on cloud network security, its benefits, challenges, and best practices for protecting your cloud environment effectively. Cloud network security: Challenges and best practices What is cloud network security? Cloud network security refers to the measures used to protect public, private, and hybrid cloud networks. These measures include technology, services, processes, policies, and controls and can defend against data exposure or misuse. Why is cloud network security important? Cloud network security is important because of the wide range of threats to data and other cloud resources. Some of the most common include data breaches and exposure, malware, phishing, compromised APIs, distributed denial-of-service (DDoS), and DNS attacks, among others. In addition to defending against threat actors, cloud networks must also comply with an ever-growing number of regulations. A cloud-native security tool can provide the protection, incident response, and compliance that organizations need. Cloud security vs. network security Network security is a type of cloud security. If used in a hybrid system, it can rely on physical barriers and protections, whereas cloud security must exclusively use virtual solutions. In cloud computing, several organizations may share resources through infrastructure-as-a-service platforms like AWS EC2. Distributed data centers mean physical cybersecurity measures, like firewalls, must be replaced with virtual projections. There are three categories of cloud security: public, private, and hybrid cloud environments. Each offers its own set of challenges, which only increase in complexity for organizations with a multi-cloud environment. Schedule a Demo How does cloud network security work? Cloud network security routes traffic using software-defined networking. These protections are different from on-premise firewall systems and are virtualized and live in the cloud. The most secure platforms are built on a zero-trust security model, requiring authentication and verification for every connection. This helps protect cloud resources and defend them throughout the threat lifecycle. Schedule a Demo The benefits of cloud network security Cloud networks are inherently complex, and managing them using native tools can leave your organization vulnerable. Using a cloud network security solution offers several advantages. Improved protection The most important benefit of a secure cloud infrastructure is better protection. Managed permissions and orchestration can help prevent breaches and ensure better security across the system. Automated compliance A security solution can also help ensure compliance through automation that reviews policies for the most up-to-date regulatory and industry requirements and deploys the policy to multiple cloud platforms from a single place. Better visibility With a comprehensive solution, you can see all your properties—including on-premise and hybrid systems—in a single pane of glass. Improved visibility means recognizing new threats faster and resolving issues before they arise. Schedule a Demo Cloud network security challenges The cloud offers several benefits over traditional networks but also leads to unique vulnerabilities. Complexity across security control layers Cloud providers’ built-in security controls, such as security groups and network ACLs, impacts security posture. There is a need to protect cloud assets such as virtual machines, DBaaS, and serverless functions. Misconfigurations can introduce security risks across various assets, including IaaS and PaaS. Cloud and traditional firewall providers also offer advanced network security products (such as Azure Firewall, Palo Alto VM-Series, Check Point CloudGuard). Multiple public clouds Today’s environment uses multiple public clouds from AWS, Azure, and GCP. Security professionals are challenged by the need to understand their differences while managing them separately using multiple consoles and diverse tools. Multiple stakeholders Unlike on-premise networks, managing deployment is especially challenging in the cloud, where changes to configurations and security rules are often made by application developers, DevOps, and cloud teams. Schedule a Demo Key layers for cloud security Robust public cloud network security architecture must include four separate areas—layers that build upon each other for an effective network security solution. Cloud security architecture is fundamentally different from its on-premise counterpart. Cloud security challenges are met by a layered approach rather than a physical perimeter. Security for AWS, Azure, or any other public cloud employs four layers of increasing protection. Layer 1: Security groups Security groups form the first and most fundamental layer of cloud network security. Unlike traditional firewalls that use both allow and deny rules, security groups deny traffic by default and only use allow rules. These security groups are similar to the firewalls of the 90s in that they’re directly connected to servers (instances, in cloud architecture terms). If this first layer is penetrated, control of the associated security group is exposed. Layer 2: Network Access Control Lists (NACLs) Network Access Control Lists (NACLs) are used to provide AWS and Azure cloud security. Each NACL is connected to a Virtual Private Network (VPN) or Virtual Private Cloud (VPC) in AWS or VNet in Azure and controls all instances of that VPC or VNet. Centralized NACLs hold both allow and deny rules and make cloud security posture much stronger than Layer 1, making Layer 2 essential for cloud security compliance. Layer 3: Cloud vendor security solution Cloud security is a shared responsibility between the customer and the vendor, and today’s vendors include their own solutions, which must be integrated into the platform as a whole. For example, Microsoft’s Azure Firewall as a Service (FWaaS), a next-generation secure internet gateway, acts like a wall between the cloud itself and the internet. Layer 4: Third-party cloud security services Traditional firewall vendors, like solutions from Check Point (CloudGuard) and Palo Alto Networks (VM-Series), need to be integrated as well. These third parties create firewalls that stand between the public clouds and the outside world. They develop segmentation for the cloud’s inner perimeter like an on-premise network. This fourth layer is key for infrastructure built to defend against the most difficult hybrid cloud security challenges .

Discover everything you need to know about Network Security Policy Management (NSPM) solutions, including their benefits, features, and how they streamline security operations. Everything you need to know about NSPM solutions | AlgoSec Overview In this IT Central Station Peer Paper, learn the key factors driving selection of Network Security Policy Management solutions based on actual user feedback. Schedule a Demo Abstract Network Security Policy Management (NSPM) solution selection factors need to align with business needs. Security shouldn’t be a barrier to the business, but frequently, security needs are shortchanged to ensure business agility. Ideally, this tradeoff should not exist. Network and security managers thus look for NSPM solutions that can make the business run better by efficiently automating network security policy management, improving visibility in network traffic and rules, and facilitating compliance. This paper offers insights and feedback from real users, who discuss what went into their NSPM selection process. Schedule a Demo Introduction What constitutes a good Network Security Policy Management (NSPM) solution? Selection criteria relate to Information Technology (IT) and security, but both tie into the business. The technical qualities of an NSPM solution should support existing business processes and help the business move forward. Security should not get in the way of business agility. Indeed, business and IT stakeholders are increasingly recognizing that security risks have a clear financial impact on your business – from reputational damage, to lost business and lower corporate valuations. Breaches are costly and time-consuming to remediate. The loss from a data breach or outage is real. The right NSPM solution enables the business to achieve its strategic and operational goals while cost-effectively mitigating risk. In this paper, enterprise IT professionals discuss how the right NSPM solution addresses such challenges through greater visibility into the network, policy automation and compliance. Their insights come from reviews of the AlgoSec NSPM solution, published on IT Central Station. Schedule a Demo The continuing evolution of NSPM Network security managers face pressure on multiple fronts. They’re dealing with increased network complexity. There are growing global compliance requirements and rules to track. The network itself now spans on-premises, public clouds, private clouds and everything in between. At the same time, the business wants to accelerate time-to-market, increase agility, produce more innovative applications and on and on—all without suffering a data breach or outage. Aligning security with businesses requirements in NSPM requires automation. Old, manual processes that rely on Visio and Excel are unable to keep up with the pace of business changes. The new generation of NSPM solutions gives network security managers and network administrators the tools they need to deliver what the business wants—without overspending or stretching network operations teams beyond reason. They do this by unifying visibility, policy automation, and compliance. All of this is happening in a complex environment. To stay secure and agile, the business needs its NSPM solution to automate the policy change process, conduct continuous network analysis, and monitor the network across the cloud and on-premises data center. Figure 1 depicts some of the elements the NSPM solution must interact with to realize such functions. Figure 1: NSPM solutions must provide visibility and automation for a wide range of network hardware, software and functional areas—on top of physical networks, private clouds frequently running software-defined networks (SDNs), and public cloud infrastructure. Schedule a Demo Challenges inherent in selecting an NSPM solution There is no NSPM solution that satisfies all needs. Every organization has different technical and business requirements and security cultures. Solutions have to fit the network, business strategies, and existing business processes. However, when evaluating an NSPM solution, there are four critical issues: Dealing with misconfigurations – Manual processes frequently lead to misconfigurations. According to industry data, nearly all firewall breaches are caused by misconfigurations, not flaws. Automating previously-manual processes results in fewer mistakes and misconfigurations. Automation as a strategy – Network policy automation is not an end unto itself. Rather, it supports the business strategy like maintaining security, ensuring SLAs, increasing cooperation and reducing friction between departments. It improves competitive differentiation through better customer engagement, e.g., by moving applications to the cloud. Network policy automation aids regulatory compliance, and frees IT time from housekeeping so it can be applied to digital transformation and supporting strategic initiatives. Understanding visibility requirements – Powerful NSPM tools give network admins and security managers new depths of visibility into both network devices and business applications. By understanding their traffic flows across multi-vendor and hybrid devices, they can plug security holes, troubleshoot more easily, and discover applications and services. Compliance requirements – Meeting an audit requirement often consumes all the IT department’s resources as they focus on auditing. Organizations need to determine their regulatory compliance requirements, decide how much time they want to spend preparing for audits, and figure out how important continuous compliance is to them. They need to make sure that new changes do not violate internal or regulatory compliance requirements. Schedule a Demo NSPM solution selection factors Members of IT Central Station, an industry site that features candid discussions and peer-to-peer user reviews from enterprise technology professionals, weighed numerous factors in their processes of selecting an NSPM solution. As they described in reviews of AlgoSec, a key consideration was the alignment of network security with business objectives. Their assessments touched on a wide variety of issues. These included the solution’s ability to reduce misconfigurations during the process of digital transformation when assets move some of their data to the cloud and organizations embrace hybrid networks. NSPM user reviews also discussed the efficiency of network management operations and team performance. Visibility and automation were significant factors affecting selection of an NSPM solution. Users want visibility into the network, traffic, and applications. They want to see what is happening with rules and applications while also monitoring policy changes. Regarding automation, what mattered to users was the ability to automate rules management, as well as configuration and change management. “Zero-touch” automation was considered useful, as was the ability to automate a multi-vendor environment. Compliance is the other main driver of NSPM selection. Users rely on their solutions to facilitate compliance, including reporting. These needs include ensuring a state of continuous compliance as well as ensuring and demonstrating audit-ready regulatory compliance for major regulations such as PCI DSS, GDPR, and SOX. Users also have to ensure and demonstrate audit readiness for internal compliance requirements. Get a Demo Schedule a Demo Network security policy as a business issue Policies governing the network are inherently business-facing. Even when they address entirely technical matters, a business objective is ultimately driving the policy process. For example, an IP network expert at a comms service provider with more than 200 employees described the value of AlgoSec by commenting, “It provides faster go to market with fewer resources. In one system, users can request access through the firewall for business services, which can be approved by the appropriate team and can be implemented automatically by the system itself.” IT Central Station members spoke to the need to align network security with business objectives. An AlgoSec user at an energy/utilities company with over 10,000 employees remarked, “With AlgoSec, we can show a view of firewall compliance that is clean and easy to read and present. This also helps our business units ensure their policies are clean. With that data, we can show management that the firewalls connected to our network, but owned by other business units, meet our standards.” A network engineer at a tech services company with over 10,000 employees, shared that AlgoSec “helps us deploy new business applications quickly and securely. It ties cyber threats directly to critical business processes.” Enabling digital transformation and cloud migrations As network managers and security teams grapple with digital transformation and cloud initiatives, they want an NSPM solution that will facilitate the process. As an AlgoSec user put it, “We see the value… for organizations involved in digital transformation projects migrating to public/ private/hybrid cloud models.” A director of information security operations at a consumer products company with over 1,000 employees, similarly shared that AlgoSec helped him with cloud support , spanning both native and hybrid environments. Optimizing team performance Network operations and security managers are keenly aware of team performance and its impact on the broader business. Budget-cutting pressure is relentless, while skills shortages potentially hamper effective operations. SLAs are a constant pressure. At the same time, the faster the team, the more agile the business. For these reasons, users view team performance optimization as a selection factor for an NSPM solution. For instance, an IT technical consultant at a manufacturing company with over 10,000 employees said that AlgoSec FireFlow “increases business efficiency and helps avoid bottlenecks in our NOC [Network Operations Center] team.” A security engineer at a financial services firm with more than 500 employees had a similar experience. He said, “Since we deployed AlgoSec, we have been able to assign more of our time to what really matters . It now takes less than half of the time it took before we had this tool to deploy the flows requested by the business.” Previously, this had been a “very painful job,” as he put it. “Now,” he added, “We just put the source and destination into the AlgoSec Firewall Analyzer and most of the job for the flows is done.” Another AlgoSec user found that the solution let him “increase the effectiveness of the team, allowing them to prioritize more complex and business-critical tasks in a faster manner.” Schedule a Demo Visibility Being able to align network security with business priorities depends on seeing what’s happening across the network as well as within its policies and rules. A manager of network service delivery at a financial services firm with over 10,000 employees summed up the issue when he said, “It is worth spending the cost for visibility on security .” A security engineer at a manufacturing company with over 1,000 employees, echoed this sentiment, commenting, “I think we have a great ROI due to the improved visibility and management that the solution now provides us.” Visibility into network and traffic The network itself is the starting point of business-oriented NSPM. Network managers must see how traffic and network policies affect the network and their applications. Without the right tooling, however, much of the network can remain hidden. To this point, an AlgoSec user at a company with over 10,000 employees said, “I use this solution to have full visibility of the network , to simulate traffic queries, and to generate security reports according to the security policies of my company. The most valuable features are the network map, which provides the full visibility of the network, and the security reports.” Another AlgoSec user spoke about the benefits of the network map, saying, it was “a very good thing to get a clear view of every single region in your network.” A lead security infrastructure consultant at a financial services firm with over 10,000 employees, added: “We also use AlgoSec to get better visibility into our traffic flows , to optimize our firewalls rules, and to analyze risks.” An AlgoSec user at a company with over 10,000 employees noted, “This solution provides visibility and comprehension of the network in our organization. It assists us in network security reviews and audits. In the end, a lot of time, we add context and build a security matrix matching our own standards.” A senior technical and integration designer at a retailer with over 10,000 employees further remarked that “AlgoSec provided a much easier way to process FCRs [Firewall Change Requests] and get visibility into traffic .” He contrasted this capability with his experience with previous vendors, a situation where, as he said, “we had to guess what was going on with our traffic and we were not able to act accordingly.” Get a Demo Visibility into applications Network managers need to understand the impact of policy changes on business-critical network applications. Security policies affect application migrations as well as initiatives to establish network segmentation. In this sense, visibility into applications on the network is essential for aligning network security policy with business objectives. The network engineer addressed the issue by stating, “It [AlgoSec] automatically discovers applications and their connectivity flows, then associates connectivity with their underlying firewall rules.” For a system architect at a school with more than 500 employees, the benefit came from the solution’s traffic simulation query. In his case, this “helps to understand which rules match or don’t match for a specific traffic pattern, helping troubleshoot application issues .” “I have found the firewall optimization feature to be very valuable because most developers don’t know the ports or services their applications are running ,” said an AlgoSec user. He then added, “After running the rules on any services for a short while, AlgoSec helps get the right service ports and IP addresses.” A network manager at a financial services firm with over 1,000 employees felt that AlgoSec has enabled his team to analyze rules to check access for an application or user. He related, “Breaking down a rule to specify used objects within groups and protocols used has proved invaluable for us to narrow exposure to potential threats.” Visibility into rules NSPM users want visibility into rules. According to an AlgoSec user, the solution “provides great visibility into your firewall rules , thereby allowing you to eliminate redundant or overlapping rules.” In particular, visibility into rules saved time by allowing his administrators to test network traffic and pinpoint which rules were being triggered for a particular traffic flow. A technical presales engineer at a tech services company with more than 500 employees, described the value of AlgoSec’s policy tightening feature, which gave him visibility into ‘any to any’ rules. The tool could tell him which sources and destinations were used as well as the actual traffic from overly permissive rules . From this, he said, “We are able to tighten the policy of the firewall.” Visibility into changes Policy changes are a potential source of risk exposure, especially in a large organization where team members may not be aware of others’ actions. IT Central Station members highlighted this capability in their assessments of NSPM solutions. “Now, we can easily track the changes in policies,” said a network security engineer at a financial services firm with over 10,000 employees. “With every change, AlgoSec automatically sends an email to the IT audit team. It increases our visibility of changes in every policy.” “The compliance module provides full visibility of the risk required in firewall change requests ,” said the manager of network service delivery. An AlgoSec user at a company with over 10,000 employees felt that “AlgoSec also allows us to have a history of changes .” He believed the history was especially useful in the event of an outage or an unwanted change. For another AlgoSec user, “Policy optimization, visibility, and a faster change management process has reduced unnecessary times required for manually changing processes. The resources are now utilized more effectively for other areas.” Schedule a Demo Automation IT Central Station members stressed the importance of automation capabilities in selecting an NSPM solution. Reliance on manual processes is unsustainable. Experience shows that manual policy management leads to mistakes, misconfigurations, and missed SLAs. As the IT technical consultant pointed out, with AlgoSec, “we have eliminated any human mistakes that we have dealt with in the past and now we want to avoid as we are moving toward a completely automated network.” Manual processes negatively affect agility as well. The issue is particularly salient today, as companies expect network operations to be as lean as possible. Automated rules management AlgoSec users are putting the solution to work in automating rules management. A network and security engineer said, “We are also using AlgoSec to automate machine provisioning (creation of new rules associated with that machine) and machine decommissioning (removal of rules associated with that machine).” This capability is viewed as a positive attribute in an NSPM solution. According to an AlgoSec user, “We are currently in a rule base performance improvement process and AlgoSec is an invaluable tool to accomplish this. Furthermore, we are starting rule creation automation , which will also provide some relief on our workload.” Other notable comments about rule management automation include: “My organization has used Firewall Analyzer for many years to simplify and automate rule set management across an estate of hundreds of Check Point firewalls. Key functionality provided covers compliance reporting and identification of duplicate and unused, as well as risky rules.” – Security consultant at a financial services firm with over 1,000 employees “We recently moved our data center to a new location, and we migrated our firewalls from one vendor to a different vendor. AlgoSec helped us tremendously to clean up shadow rules , unused objects even before moving to a new vendor.” – AlgoSec user at a healthcare company with over 1,000 employees “Our primary use case is to clean up firewall rules of migration from Cisco ASA to another firewall vendor. We try to get rid of old rules and get these converted into new rules which apply better to our environment.” – AlgoSec User Automated configuration and change management Being able to automate configuration and change management saves time. As a result, it’s a driver of preference for NSPM solutions. “Automated change notification is a must and is critical in maintaining a safe environment and compliance,” said an AlgoSec user. An information security specialist at a company with over 10,000 employees also spoke to this benefit of AlgoSec when he said, “The best feature for us is the ability to automate the change requests that come through our service desk, which is done via the tool’s intelligence to analyze the conditional rules.” In his case, as he put it, “This used to be a big time sink for the guys which is now less of an issue. This means that the company can claim back valuable man-hours for other means (also showing a labor cost saving to the board).” Zero-touch automation To achieve the productivity gains desired by network security and operations managers, an NSPM solution should enable automation with as few hours as possible. The network engineer acknowledged AlgoSec in this regard, saying, “AlgoSec delivers a rich set of change management workflows and enables zero-touch change processes if no risks are identified.” A global network security engineer similarly noted, “Initial deployment was straightforward . The FireFlow workflow can be configured to match the existing flow – customizing this to match any workflow permutations takes the most time.” Automating the multi-vendor environment Network security and operations environments are often multi-vendor in nature. They invariably have to support firewalls from Check Point, Fortinet, and Palo Alto as well as a host of other technologies, as shown in Figure 2. For this reason, users prefer NSPM solutions that work well with more than one vendor platform. An IT Security Engineer III at a software company with over 10,000 employees, shared how he had previously spent time manually looking through rule bases trying to find risk rules. “Now we see it via AlgoSec,” he said, adding, “It also helps because we see those risks across multiple vendors .” This reduced the potential for error, in his view. A senior consultant at a consultancy said, “We use this solution for the management of firewalls on a client with a multi-vendor landscape .” An AlgoSec user at an energy/utilities company with over 1,000 employees valued AlgoSec’s “ability to manage multiple vendor firewall policies and traditional firewalls with an intelligent way to prevent cyberattacks and reduce outages.” The AlgoSec user at the energy/utilities company further noted, “We are moving towards an automated environment so the ability to work with Ansible, ServiceNow, and Palo Alto gives us the ability to automate our firewall policy creation. And it does so in a manner where we do not have to worry about a policy being created that may put our organization at risk.” Figure 2: Some of the platforms and technologies with which an NSPM solution should integrate Schedule a Demo Compliance An NSPM solution must make it easier to enforce the network-level policies required for compliance with government regulations, such as Sarbanes-Oxley (SOX) and PCI DSS, than is possible without the solution. NSPM should also make it simpler to bring the network into compliance with internal-facing security policies and rules, e.g., “Routers may not be set to factory defaults.” These expectations are increasingly relevant as organizations adopt continuous compliance—no longer treating audits as a point-in-time exercise but rather working to adhere to policies and controls and continually maintaining compliance, even during frequent and extensive network changes. For example, a security consultant in a financial services firm with over 1,000 employees said, “Compliance and risk reporting are the most valuable features of the product.” A Global Network Solution Architect at AXA, an insurance company with over 10,000 employees, used AlgoSec for firewall rules compliance with global security policies. He relied on the solution “to ensure global policies are applied to all regional firewalls, provide auditing and compliance.” Firewall compliance Network managers need to demonstrate that their firewalls comply with policies established to meet the audit requirements of regulations like SOX and HIPAA. This is a familiar aspect of network management and security, but one that gets revisited regularly as users try to make the process more efficient. In this context, the Prudential manager of network service delivery stated, “The compliance module is one of the best features which can help anyone to perform security review with predefined security matrix configurations. The compliance module can save a lot of time for security reviews and provide full visibility of the risk required in firewall change requests.” The security engineer said, “It’s a great tool when preparing for audits and ensuring your firewalls are in compliance .” Regulatory compliance Companies that are obligated to comply with government regulations benefit from automated policy management. The network engineer, for example, found that using an NSPM solution reduced his audit preparation efforts and costs drastically while enabling his team to maintain continuous compliance. An AlgoSec user also felt the solution helped in maintaining and providing regulatory compliance metrics and optimizing the overall security of the organization. The PCI DSS compliance standard, required for companies that process credit card transactions, emerged as a frequent use case for NSPM: “The baseline of in-built policies such as PCI DSS helps us maintain good security ratings in compliance with regulatory standards.” – Security operations manager at a financial services firm with more than 200 employees “I work at a multi-vendor firewall environment. AlgoSec is primarily used to see what firewall policies are in place, as well as PCI compliance ” – Senior firewall engineer at a tech consulting company with over 1,000 employees “It is very useful for PCI DSS compliance .” – Presales manager at a small company Internal Compliance IT Central Station members discussed their internal compliance needs as well. The network manager placed this issue into context by saying, “The risk and compliance area is key to ensuring we conform to company regulations . Having a number of compliance options to baseline ensures that we get the basics right before looking at advanced risks and remediation.” Addressing this point, the security engineer said, “We also need the audit report and risk assessment features to send to our InfoSec team so that they can use it in our audit documentation . This is also very important because it significantly reduces our workload and makes it very easy to have the documentation ready to show to our auditors.” The network and security engineer was pleased that AlgoSec enabled his team to provide reports to auditors “without losing a single day from the network support department.” He said, “We simply provide AlgoSec reports and analysis.” Another AlgoSec user acknowledged AlgoSec’s ability to help him prepare for the audit in a short time and assist with continuous compliance . The network manager added, “The risk and compliance area is key to ensuring we conform to company regulations .” A network administrator at a government agency with over 10,000 employees, simply stated, “For us, it is a great management and audit tool .” Schedule a Demo Conclusion Many factors come into play in the selection of a network security policy management solution. In a business environment, where companies want to be agile, users want solutions that offer visibility into traffic and applications. For IT Central Station members, a good solution automates rules management along with configuration and change management. The best solution will also facilitate compliance, both internal and regulatory. With these qualities, an NSPM will be able to align security with business and make sure that your network adheres to your stated security policies.
