Implement micro-segmentation effectively, from strategy to execution, to enhance security, minimize risks, and protect critical assets across your network. Micro-segmentation from strategy to execution Overview Learn how to plan and execute your micro-segmentation project in AlgoSec’s guide. Schedule a Demo What is Micro segmentation Micro-segmentation is a technique to create secure zones in networks. It lets companies isolate workloads from one another and introduce tight controls over internal access to sensitive data. This makes network security more granular. Micro-segmentation is an “upgrade” to network segmentation. Companies have long relied on firewalls, VLANs, and access control lists (ACL) to segment their network. Network segmentation is a key defense-in-depth strategy, segregating and protecting company data and limiting attackers’ lateral movements. Consider a physical intruder who enters a gated community. Despite having breached the gate, the intruder cannot freely enter the houses in the community because, in addition to the outside gate, each house has locks on its door. Micro-segmentation takes this an additional step further – even if the intruder breaks into a house, the intruder cannot access all the rooms. Schedule a Demo Why Micro-segment? Organizations frequently implement micro-segmentation to block lateral movement. Two common types of lateral movements are insider threats and ransomware. Insider threats are employees or contractors gaining access to data that they are not authorized to access. Ransomware is a type of malware attack in which the attacker locks and encrypts the victim’s data and then demands a payment to unlock and decrypt the data. If an attacker takes over one desktop or one server in your estate and deploys malware, you want to reduce the “blast radius” and make sure that the malware can’t spread throughout the entire data center. And if you decide not to pay the ransom? Datto’s Global State of the Channel Ransomware Report informs us that: The cost of downtime is 23x greater than the average ransom requested in 2019. Downtime costs due to ransomware are up by 200% year-over-year. Schedule a Demo The SDN Solution With software-defined networks, such as Cisco ACI and VMware NSX, micro-segmentation can be achieved without deploying additional controls such as firewalls. Because the data center is software-driven, the fabric has built-in filtering capabilities. This means that you can introduce policy rules without adding new hardware. SDN solutions can filter flows both inside the data center (east-west traffic) and flows entering or exiting the data center (north-south traffic). The SDN technology supporting your data center eliminates many of the earlier barriers to micro-segmentation. Yet, although a software-defined fabric makes segmentation possible, there are still many challenges to making it a reality. Schedule a Demo What is a Good Filtering Policy A good filtering policy has three requirements: 1 – Allows all business traffic The last thing you want is to write a micro-segmented policy and have it break necessary business communication, causing applications to stop functioning. 2 – Allows nothing else By default, all other traffic should be denied. 3 – Future-proof “More of the same” changes in the network environment shouldn’t break rules. If you write your policies too narrowly, then any change in the network, such as a new server or application, could cause something to stop working. Write with scalability in mind. How do organizations achieve these requirements? They need to know what the traffic flows are as well as what should be allowed and what should be denied. This is difficult because most traffic is undocumented. There is no clear record of the applications in the data center and what network flows they depend on. To get accurate information, you need to perform a “discovery” process. Schedule a Demo A Blueprint for Creating a Micro-segmentation Policy Micro-segmentation Blueprint Discovery You need to find out which traffic needs to be allowed and then you can decide what not to allow. Two common ways to implement a discovery process are traffic-based discovery and content-based discovery. Traffic-Based Discovery Traffic-based discovery is the process of understanding traffic flows: Observe the traffic that is traversing the data center, analyze it, and identify the intent of the flows by mapping them to the applications they support. You can collect the raw traffic with a traffic sniffer/network TAP or use a NetFlow feed. Content-based or Data-Based Approach In the content-based approach, you organize the data center systems into segments based on the sensitivity of the data they process. For example, an eCommerce application may process credit card information which is regulated by the PCI DSS standard. Therefore, you need to identify the servers supporting the eCommerce application and separate them in your filtering policy. Discovering traffic flows within a data center Micro-segmentation Blueprint Using NetFlow for Traffic Mapping The traffic source on which it is easiest to base application discovery is NetFlow. Most routers and switches can be configured to emit a NetFlow feed without requiring the deployment of agents throughout the data center. The flows in the NetFlow feed are clustered into business applications based on recurring IP addresses and correlations in time. For example, if an HTTPS connection from a client at 172.7.1.11 to 10.3.3.3 is observed at 10 AM, and a PostgreSQL connection from the same 10.3.3.3 to 10.1.1.1 is observed 0.5 seconds later, it’s clear that all three systems support a single application, which can be labeled with a name such as “Trading System”. 172.7.1.0/2410.3.3.3 TRADE SYS HTTPS10.3.3.3 TRADE SYS 10.1.1.11 DB TCP/543210.3.3.7 FOREX 10.1.1.11 DB TCP/5432 Identifying traffic flows in common, based on shared IP addresses NetFlow often produces thousands of “thin flow” records (one IP to another IP), even for a single application. In the example above, there may be a NetFlow record for every client desktop. It is important to aggregate them into “fat flows” (e.g., that allows all the clients in the 172.7.1.0/24 range). In addition to avoiding an explosion in the number of flows, aggregation also provides a higher-level understanding, as well as future-proofing the policies against fluctuations in IP address allocation. Using the discovery platform in the AlgoSec Security Management Suite to identify the flows in combination with information from your firewalls can help you decide where to put the boundaries of your segments and which policies to put in these filters. Micro-segmentation Blueprint Defining Logical Segments Once you have discovered the business applications whose traffic is traversing the data center (using traffic-based discovery) and have also identified the data sensitivity (using a content-based approach) you are well positioned to define your segments. Bear in mind that all the traffic that is confined to a segment is allowed. Traffic crossing between segments is blocked by default – and needs to be explicitly allowed by a policy rule. There are two potential starting points: Segregate the systems processing sensitive data into their own segments. You may have to do this anyway for regulatory reasons. Segregate networks connecting to client systems (desktops, laptops, wireless networks) into “human-zone” segments. Client systems are often the entry points of malware, and are always the source of malicious insider attacks. Then, place the remaining servers supporting each application, each in its own segment. Doing so will save you the need to write explicit policy rules to allow traffic that is internal to only one business application. Example segment within a data center Micro-segmentation Blueprint Creating the Filtering Policy Once the segments are defined, we need to write the policy. Traffic confined to a segment is automatically allowed so we don’t need to worry about it anymore. We just need to write policy for traffic crossing micro-segment boundaries. Eventually, the last rule on the policy must be a default-deny: “from anywhere to anywhere, with any service – DENY.” However, enforcing such a rule in the early days of the micro-segmentation project, before all the rest of the policy is written, risks breaking many applications’ communications. So start with a (totally insecure) default-allow rule until your policy is ready, and then switch to a default-deny on “D-Day” (“deny-day”). We’ll discuss D-Day shortly. What types of rules are we going to be writing? Cross segment flows – Allowing traffic between segments: e.g., Allow the eCommerce servers to access the credit-card Flows to/from outside the data center – e.g., allow employees in the finance department to connect to financial data within the data center from their machines in the human-zone, or allow access from the Internet to the front-end eCommerce web servers. Users outside the data center need to access data within the data center Micro-segmentation Blueprint Default Allow – with Logging To avoid major connectivity disruptions, start your micro-segmentation project gently. Instead of writing a “DENY” rule at the end of the policy, write an “ALLOW” rule – which is clearly insecure – but turn on logging for this ALLOW rule. This creates a log of all connections that match the default-allow rule. Initially you will receive many logs entries from the default-allow rule; your goal in the project is to eliminate them. To do this, you go over the applications you discovered earlier, write the policy rules that support each application’s cross-segment flows, and place them above the default-allow rule. This means that the traffic of each application you handle will no longer match the default-allow (it will match the new rules you wrote) – and the amount of default-allow logs will decrease. Keep adding rules, application by application, until the final allow rule is not generating any more logs. At that point, you reach the final milestone in the project: D-Day. Micro-segmentation Blueprint Preparing for “D-Day” Once logging generated by the default-allow rule ceases to indicate new flows that need to be added to your filtering policy, you can start preparing for “D-Day.” This is the day that you flip the switch and change the final rule from “default ALLOW” to “default DENY.” Once you do that, all the undiscovered traffic is going to be denied by the filtering fabric, and you will finally have a secured, micro-segmented, data center. This is a big deal! However, you should realize that D-Day is going to cause a big organizational change. From this day forward, every application developer whose application requires new traffic to cross the data center will need to ask for permission to allow this traffic; they will need to follow a process, which includes opening a change request, and then wait for the change to be implemented. The free-wheeling days are over. You need to prepare for D-Day. Consider steps such as: Get management buy-in Communicate the change across the organization Set a change control window Have “all hands on deck” on D-Day to quickly correct anything that may have been missed and causes applications to break Micro-segmentation Blueprint Change Requests & Compliance Notice that after D-Day, any change in application connectivity requires filing a “change request”. When the information security team is evaluating a change request – they need to check whether the request is in line with the “acceptable traffic” policy. A common method for managing policy at the high-level is to use a table, where each row represents a segment, and every column represents a segment. Each cell in the table lists all the services that are allowed from its “row” segment to its “column” segment. Keeping this table in a machine readable format, such an Excel spreadsheet, enables software systems to run a what-if risk-check that compares each change-request with the acceptable policy, and flags any discrepancies before the new rules are deployed. Such a what-if risk-check is also important for regulatory compliance. Regulations such as PCI and ISO27001 require organizations to define such a policy, and to compare themselves to it; demonstrating the policy is often part of the certification or audit.

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.

Proactively manage vulnerabilities with application-centric strategies. Prioritize risks, enhance visibility, and secure your applications across complex environments. Application-centric vulnerability management Assess and prioritize vulnerabilities from the business perspective Vulnerability management has always been a cornerstone of a sound information security program, but traditional scanners uncover too many vulnerabilities for any business to adequately address. Additionally, vulnerability information is typically presented for IP addresses and servers, and not in a context that business owners can understand. Given the number of vulnerabilities across the network, effectively prioritizing risk and remediation efforts based on the business application and existing firewall risks has a major impact on security and business productivity. Schedule a Demo Application-centric vulnerability management AlgoSec AppViz integrates with leading vulnerability scanners to map vulnerabilities with their associated data center applications, including their servers and complex connectivity requirements. Organizations can view network vulnerabilities with the business in mind. As application components, connectivity requirements, and vulnerabilities frequently change, AlgoSec ensures organizations have the most up-to-date and accurate information to prioritize risk.

Automate network management and policy changes to increase efficiency, reduce errors, and ensure security compliance across your network infrastructure. Network management & policy change automation Overview This eBook provides practical suggestions for implementing a change automation process, lays out the pitfalls, and gives practical tips for choosing a change management solution. Schedule a Demo Cure the network management headache In today’s IT environment, the only constant is change. Business needs change. As your business changes, so must your security policies. The problem Change comes with challenges, leading to major headaches for IT operations and security teams. This develops into huge business problems: Manual workflows and change management processes are time-consuming and hinder business agility. Improper management changes lead to serious business risks – as benign as blocking legitimate traffic all the way to network outages. The solution Automation and actionable intelligence can enhance security and business agility – without the headaches and misconfigurations caused by manual, ad-hoc processes. In this document, you will learn the secrets of how to elevate your firewall change management from manual labor-intensive work to a fully automated zero-touch change management process. Schedule a Demo Why’s it hard to change network policies? Placing a sticky note on your firewall administrator’s desk or sending an email that gets lost in the clutter and expecting the change request to be performed pronto does not constitute a formal policy. Yet, shockingly, this is common. You need a formal change request process. Such a process dictates defined and documented steps about how to handle a change request, by whom, how it is addressed, defines an SLA, and more. Firewall change management requires detailed and concise steps that everyone understands and follows. Exceptions must be approved and documented so stakeholders can understand the risk. Your security policy management solution should seamlessly integrate with the tools you are already using to accelerate its adoption in your organization. AlgoSec enables business agility by integrating with ITSM systems like ServiceNow, BMC Helix ITSM (formerly Remedy), Clarity SM (formerly CA Service Management) and HP Service Management. Communication breakdown Network security and IT operations staff work in separate silos. Their goals, and even their languages, are different. Working in silos is a clear path to trouble. It is a major contributor to out-of-band changes that result in outages and security breaches. In many large companies, routine IT operational and administrative tasks may be handled by a team other than the one that handles security and risk. Although both teams have the same goal, decisions made by one team lead to problems for the other. Network complexity is a security killer Today’s networks exist across complex environments – on-premise data centers, multiple multi-vendor public and private clouds, spanning geographic borders. It’s difficult to keep track of your entire network estate. Security expert Bruce Schneider once stated that “Complexity is the worst enemy of security.” The sheer complexity of any given network can lead to a lot of mistakes. Simplifying and automating the firewall environment and management processes is necessary. Did you know? Up to 30 percent of implemented rule changes in large firewall infrastructures are unnecessary because the firewalls already allow the requested traffic! Under time pressure, firewall administrators often create rules that turn out to be redundant. This wastes valuable time and makes the firewalls even harder to manage. Get a Demo Schedule a Demo Mind the security gap Introducing new things open up security gaps. New hires, software patches, upgrades, server migrations, and network updates increase your exposure to risk. Who can keep track of it all? What about unexpected, quick fixes that enable access to certain resources or capabilities? A fix is made in a rush (after all, who wants a C-level exec breathing down their neck because he wants to access resources RIGHT NOW?) without sufficient consideration of whether that change is allowed under current security policies. Problems abound when speed is mistaken for agility and takes precedence over security. You need to be able to make changes fast and accurately – agility without compromising security. How can you get both agility and security? Network automation. There are solutions that automate firewall management tasks and record them so that they are part of the change management plan. Network automation helps bridge the gap between change management processes and reality. A sophisticated firewall and topology-aware system that identifies redundant change requests increases productivity. IT and security teams are responsible for making sure that systems function properly. However, they approach business continuity from different perspectives. The security department’s goal is to protect the business and its data, while the IT operations team focuses on keeping systems up and running. The business has to keep running AND it has to be secure. Alignment is easier said than done. To achieve alignment, organizations must reexamine IT and security processes. Let’s take a look at some examples of what happens when there is no alignment. Schedule a Demo Good changes gone bad Example 1 A classic lack of communication between IT operations and security groups put Corporation XYZ at risk. An IT department administrator, trying to be helpful, took the initiative to set up (with no security involvement or documentation) a file share for a user who needed to upload files in a hurry. By making this off-the-cuff change, the IT admin quickly addressed the client’s request. However, the account lingered unsecured. The security team noticed larger spikes of inbound traffic to the server from this account. Hackers abound. The site had been compromised and was being exploited. Example 2 A core provider of e-commerce services suffered a horrible fate due to a simple, but poorly managed, firewall change. One day, all e-commerce transactions in and out of its network ceased. The entire business was taken offline for several hours. The costs were astronomical. What happened? An out-of-band (and untested) change to a core firewall broke communications between the e-commerce application and the internet. Business activity ground to a halt. Because of this incident, executive management got involved and the responsible IT staff members were reprimanded. Hundreds of thousands of dollars later, the root cause of the outage was uncovered: IT staff chose not to test their firewall changes, bypassing their “burdensome” ITIL-based change management procedures. They failed to consider the consequences. Schedule a Demo Avoiding a firewall fire drill Automation is the key to gaining control. It helps staff disengage from firefighting. It bridges between agility and security to drive business-driven productivity. The right automation solution automates manual, error-prone workflows. It allows changes to be made accurately, with clear visibility across complex network topologies, while focusing on keeping the business running effectively. Automation helps teams track down potential traffic or connectivity issues and highlights risky areas. It can automatically pinpoint devices that require changes and show how to create and implement the changes. To ensure proper balance between business continuity and security, look for a firewall policy management solution that: Provides visibility of network traffic flows and network devices across complex, hybrid and multi-cloud network topologies Intelligently designs firewall rules to eliminate redundant rules and reduce clutter and complexity. Eliminates mistakes and rework. Improves accountability for change requests. Proactively assesses the impact of network changes to ensure security and continuous compliance. Identifies risky security policy rules and offers suggestions to de-risk your network environment Automatically pushes changes to devices Schedule a Demo 10 steps to automate and standardize the firewall change-management process Once a request is made, a change-request process should include these steps: Clarify the change request and determine the dependencies. Obtain all relevant information (i.e., who is requesting the change and why). Validate that the change is necessary. Many requests are unnecessary and already covered by existing rules. Get proper authorization for the change. Make sure you understand the dependencies and the impact on business applications, and other devices and systems. This usually involves multiple stakeholders from different teams. Perform a risk assessment. Before approving the change, thoroughly test it and analyze the results so as not to block desired traffic or violate compliance. Does the proposed change create a new risk in the security policy? Plan the change. Assign resources, create and test your back-out plans, and schedule the change. This is also a good time to ensure that everything is properly documented for troubleshooting or recertification purposes. Execute the change. Backup existing configurations, prepare target device(s) and notify appropriate workgroups of any planned outage, and then perform the actual change. Verify correct execution to avoid outages. Test the change, including affected systems and network traffic patterns. Audit and govern the change process. Review the executed change and any lessons learned. Having a non-operations-related group conduct the audit provides the necessary separation of duties and ensures a documented audit trail for every change. Measure SLAs. Establish new performance metrics and obtain a baseline measurement. Recertify policies. Part of your change management process should include a review and recertification of policies at a regular, defined interval (e.g., once a year). This step forces you to review why policies are in place, enabling you to improve documentation and remove or tweak policy rules. Schedule a Demo What to look for in a change-management solution Your solution must be firewall- and network-aware. This allows the system to pull information from the firewalls and understand the current policies. Your solution must support the firewalls, routers, security controls, load balancers, and other devices across your hybrid network. Your solution must be topology-aware. It must understand how the network is laid out, comprehend how the devices fit and interact, and provide the necessary visibility of how traffic is flowing through the network. Your solution must integrate with the existing general change management systems. You don’t want to undergo massive retraining of processes and systems simply because you have introduced a new solution. Your solution must provide out-of-the-box change workflows to streamline change-management processes and be highly customizable. No two organizations’ network and change processes are exactly the same. Schedule a Demo Summary While change management is complex stuff, the decision for your business is simple. You can continue to slowly chug along with manual change management processes or you can accelerate those processes with an automated network change management workflow solution that aligns stakeholders and helps your business run more smoothly. Think of your change process as a key component of the engine of an expensive car (in this case, your organization). Would you drive your car at high speed if you didn’t have tested, dependable brakes or a steering wheel? Hopefully, the answer is no! The brakes and steering wheel are analogous to change controls and processes. Rather than slowing you down, they actually make you go faster, securely! “Accelerate your business with security policy change automation” Power steering and power brakes (in this case firewall-aware integration and automation) help you zoom to success.

A network security policy is a critical part of your IT cyber policy It helps determine what traffic is allowed on your network, keeping critical assets secure Network security policy examples & procedures Introduction A network security policy delineates guidelines for computer network access, determines policy enforcement, and lays out the architecture of the organization’s network security environment and defines how the security policies are implemented throughout the network architecture. Network security policies describes an organization’s security controls. It aims to keep malicious users out while also mitigating risky users within your organization. The initial stage to generate a policy is to understand what information and services are available, and to whom, what the potential is for damage, and what protections are already in place. The security policy should define the policies that will be enforced – this is done by dictating a hierarchy of access permissions – granting users access to only what they need to do their work. These policies need to be implemented in your organization written security policies and also in your IT infrastructure – your firewall and network controls’ security policies. Schedule a Demo What is network security policy management? Network security policy management refers to how your security policy is designed and enforced. It refers to how firewalls and other devices are managed. Schedule a Demo Cyber Security Policies as Part of IT Security Policy A good IT security policy contains the following essentials: Purpose Audience Information security objective Authority and access control policy – This includes your physical security policy Data classification Data support and operations Security awareness and behavior Responsibility, rights, and duties A cyber security policy is part of your overall IT security. A cybersecurity policy defines acceptable cybersecurity procedures. Cybersecurity procedures explain the rules for how anyone with potential network access can access your corporate resources, whether they are in your physical offices, work remotely, or work in another company’s offices (for example, customers and suppliers), send data over networks. They also determine how organization’s manage security patches as part of their patch management policy. A good cybersecurity policy includes the systems that your business is using to protect your critical information and are already in place, including firewalls. It should align with your network segmentation and micro-segmentation initiatives. Schedule a Demo How AlgoSec helps you manage your network security policy?

Firewall configuration: What is it? How does it work? Firewalls can greatly increase the security of enterprise networks, and enable organizations to protect their assets and data from malicious actors. But for this, proper firewall configuration is essential. Firewall configuration involves configuring domain names and Internet Protocol (IP) addresses and completing several other actions to keep firewalls secure. Firewall policy configuration is based on network types called “profiles” that can be set up with security rules to prevent cyber attacks. Schedule a demo Watch a video Firewall configuration challenges Configuring firewalls can raise many challenges Finding the right firewall It can be overwhelming to decide between a hardware or software firewall, so make sure you first determine your business needs and network configuration. Software firewalls can protect individual machines against harmful traffic; hardware firewalls are suitable for protecting enterprise networks. Broad firewall policy configurations During firewall setup, broad approvals policies that allow traffic from any source to any destination can expose the network to several security risks. It’s safer to implement narrow permissions from the start by following the Principle of Least Privilege (POLP). These firewall rule configurations can be widened later as required. Non-standard authentication With non-standard authentication methods, your firewall could accept weaker passwords or place less stringent limits on the number of login attempts allowed. This increases the risk of cybersecurity breaches. For safety, use only standard authentication methods. Open ports and risky management services Cybercriminals leverage open firewall ports and dynamic routing protocols to penetrate and exploit enterprise networks. Disable open ports at the time of firewall configuration. Other open ports should be adequately protected. Inadequate firewall monitoring If firewalls are not monitored, you may miss signs of unusual traffic that could indicate the presence of cyber attackers. Always monitor and log outputs from security devices so you will be alerted if you’re under attack. If an attacker does break through, alerts reduce the time to response. Guest or public networks: Use this profile when the system is connected to a public network. It’s best to set restrictive access because the other systems on the network could be potentially harmful. Private networks: Use this profile when connected to a network in workgroup mode. Set access to medium levels since the other systems can be mostly trusted. Domain networks: This profile is used when networks are connected to an Active Directory (AD) domain. A group policy controls the firewall settings. What are the network profiles for firewall configuration? A typical enterprise-level network is segregated into multiple security zones or “rings”: Ring 1: The Internet Edge Ring 2: The Backbone Edge Ring 3: The Asset Network Edge Ring 4: Local Host Security These zones are a logical way to group the firewall’s physical and virtual interfaces, and control traffic. Traffic can flow freely within a zone, but not between different zones until you define and allow it within the firewall policy configuration. In general, more zones means a more secure network What is the role of security zones in firewall settings? Yes, you can create a filter with a list of words, phrases and variations to be blocked. Configure your firewall settings to “sniff” each packet of traffic for an exact match of this text. Can I configure my firewall to block specific words or phrases? For each network profile, a firewall displays status information like: Profile currently in use Firewall state (On or Off) Incoming connections and current policy Active networks Notification state What information does a firewall display for each network profile? You can set firewall filters for all these protocols: Internet Protocol (IP) to deliver information over the Internet Transmission Control Protocol (TCP) to break apart and reconstruct information over the Internet HyperText Transfer Protocol (HTTP) for web pages User Datagram Protocol (UDP) for information that requires no user response File Transfer Protocol (FTP) to upload/download files Simple Mail Transport Protocol (SMTP) for sending text-based information via email Simple Network Management Protocol (SNMP) to collect system information from a remote computer Telnet to perform commands on a remote computer What are the protocols you can set firewall filters for? Here’s a 6-step secure firewall setup process: Secure the firewall Update with the latest firmware Replace default passwords with strong, unique passwords Avoid using shared user accounts Disable Simple Network Management Protocol (SNMP) or configure it securely Restrict incoming/outgoing traffic for TCP Create firewall zones Group assets into zones based on functions and risk levels Set up the IP address structure to assign zones to firewall interfaces Configure Access Control Lists (ACLs) Make them specific to the source and destination port numbers and IP addresses Create a “deny all” rule to filter out unapproved traffic Create an ACL (inbound/outbound) for each interface and sub-interface Disable admin interfaces from public access Disable unencrypted firewall management protocols Configure firewall logging Critical if PCI DSS compliance is a requirement Disable extra/unused services Test the firewall configuration Ensure the correct traffic is being blocked Perform penetration testing and vulnerability scanning Securely back up the configuration After you complete the firewall setup, manage and monitor it continuously to ensure that it functions as intended What are the firewall configuration steps?

The NIST Cybersecurity Framework as well as other NIST security standards help set clear best practices for organizational cyber and network security NIST standards & cybersecurity framework explained The National Institute for Standards and Technology (NIST) is a US government agency, under the Commerce Department, whose mission is to set several types of standards, including security standards. Some NIST data security standards include NIST 800-53, which offers security controls and privacy controls in the areas of application security, mobile, and cloud computing, and supply chain security, NIST 800-53/FI, which establishes standards to implement FISMA , NIST 800-30, which provides guidelines for conducting risk assessments, NIST 800-171, pertaining to the physical security of data centers, and ISO 27001 . White Paper Solution Overview Understanding the NIST Cybersecurity Framework One of the most widely used NIST security standard is the NIST Cybersecurity Framework (CSF). This internationally recognized framework offers voluntary guidance, based on existing standards, guidelines, and practices for organizations to better manage and reduce cybersecurity risk. It provides companies with an easy-to-understand common language for talking about cybersecurity risk, no matter where they are on the org chart – from the server room to the board room. The NIST Cybersecurity Framework identifies five core functions: Identify Protect Detect Respond Recover The framework describes desired outcomes that are understandable by everyone, applies to any kind of risk management, defines the entire breath of cybersecurity, and spans both prevention and reaction. Webinar Infographic FAQ ABOUT NIST CYBERSECURITY STANDARDS Understanding NIST Cybersecurity Standards is a crucial part of your network security compliance posture. There are many international regulations that your organization needs to be compliant with, including HIPPA , PCI DSS , GDPR , NIST , ISO 27001, and Sarbanes-Oxley (SOX). Do the NIST Cybersecurity Standards provide a checklist of what all organization should do? No. The framework provides guidance that should be customized by different organizations to best suit their unique risks, situations, and needs. Organizations have different risks, threats, vulnerabilities, and risk tolerance. They will also differ in how they implement the practices in the framework. It should not be implemented as an un-customized checklist or take a one-size-fits-all approach How does my firewall management help with NIST Standards and the NIST Cybersecurity Framework? NIST Special Publication 800-41 establishes guidelines for firewalls and firewall policies, which govern standards and best practices for firewall policy management. According to the guidelines, an organization’s firewall policies should be based on a comprehensive risk-assessment. Firewall policies should be based on blocking all inbound and outbound traffic (“Default Deny”), with exceptions made for desired traffic. Policies should consider the source and destination of the traffic, in addition to the content. Many types of IPv4 traffic, such as those with invalid or private addresses, should be blocked by default. Organizations also should have policies for handling incoming and outgoing IPv6 traffic. Organizations should also determine which applications may send traffic into and out of its network and make firewall policies to block traffic for other applications. According to the guidelines (5.2.2), “if multiple firewalls need to have the same rules or a common subset of rules, those rules should be synchronized across the firewalls. This is usually done in a vendor-specific fashion.” AlgoSec provides out-of-the-box regulatory compliance reports for NIST SP 800-41. What about NIST SP 800-53? NIST SP 800-53, Security and Privacy Controls for Federal Information Systems and Organizations, relates to systems, including firewalls, that monitor and control at the external boundaries of the network and systems that connect to parts of the network. It provides extensive standards for firewall management. AlgoSec provides out-of-the-box regulatory compliance reports for NIST SP 800-53. Do NIST standards also relate to FISMA compliance? How AlgoSec Helps with NIST Standards? FISMA sets out guidelines for managing information security that must be followed for all information systems used or operated by a U.S. federal government agency in the executive or legislative branches, or by a contractor or other organization on behalf of a federal agency in those branches. By following NIST Cybersecurity Guidelines and NIST’s guidelines for firewalls and firewall policies, organizations get closer to FISMA compliance. AlgoSec helps identify traffic flows and associate it with the relevant business applications, and design firewall policies that work across your hybrid network, all with zero-touch automation to reduce the chances of manual misconfigurations. AlgoSec also helps manage and synchronize rules across the multi-vendor estate, so there is holistic and unified management across a network made up of multiple vendors. By using AlgoSec, organizations can be sure that their security management practices follow best practices such as NIST standards. AlgoSec automatically generates pre-populated, audit-ready compliance reports for leading industry regulations, including NIST SP 800-53, NIST SP 800-41, SOX, GLBA, PCI DSS, and ISO 27001— which helps reduce audit preparation efforts and costs. AlgoSec also uncovers gaps in organization’s compliance posture and proactively checks every change for compliance violations.
