Put Out Network Security Audit & Compliance Fires The growing body of regulations and standards forces enterprises to put considerable emphasis on compliance verified by ad hoc and regular auditing of security policies and controls. While regulatory and internal audits entail a wide range of security checks, network firewalls are featured prominently as they are the first line of defense of the enterprise network. Typical networks might include tens or hundreds of firewalls from multiple vendors running thousands of rules. Auditing firewalls for compliance is becoming more complex and demanding all the time. Documentation of current rules and their evolution of changes is lacking Time and resources required to find, organize and inspect all the firewall rules to determine the level of compliance is exorbitant and growing It’s time to adopt auditing’s best practices to maintain continuous compliance. Join us in this webinar to discover the Firewall Audit Checklist, the 6 best practices that will ensure successful audits and full compliance. By adopting these best practices, security teams will significantly improve their network’s security posture and reduce the pain of ensuring compliance with regulations, industry standards and corporate policies.

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 7/13/22 Published Eric Jeffery, AlgoSec’s regional solutions engineer, gives his view on the pivotal role of AppSec network engineers and how they can positively impact the business It may surprise many people but the number one skills gap hampering today’s application security network engineers is primarily centred around the soft skills which includes communication, writing, presentation, team building and critical thinking. Why is this so important? Because first and foremost, their goal is to manage the organization’s security posture by deploying the best application security tools and technologies for the specific security and growth needs of the business. Keep things safe but don’t get in the way of revenue generation What an application security network engineer should not do is get in the way of developing new business-critical or revenue generating applications. At the same time, they need to understand that they have a leadership role to play in steering a safe and profitable course for the business. Starting with an in depth understanding of all wired traffic, AppSec network engineers need to know what applications are running on the network, how they communicate, who they communicate with and how to secure the traffic and connectivity flow associated with each one of them. An AppSec network engineer’s expertise should extend much more than mastering simple applications such as FTP and SSH. Rather, business traffic continuity should sit at the pinnacle of their responsibilities. There’s a lot of revenue generating traffic that they need to understand and put the right guardrails to protect it. However, equally as important, they need to make sure that the traffic is not hindered by outdated or irrelevant rules and policies, to avoid any negative financial impact on the organization. Layers of expertise beyond the OSI model A good starting point for any AppSec network engineer is to acquire a commanding knowledge of the seven layers of the OSI model, especially Layer 6 which covers Presentation. In practical terms, this means that they should have a thorough understanding of the network and transport layers – knowing what traffic is going across the network and why. It’s also helpful to have basic scripting knowledge and an understanding of simple scripts such as a cron job for scheduling tasks. It could also be useful to know some basic level programming like Perl and PHP. Beyond the network skills, AppSec network engineers should grasp the business vertical in which they operate. Once they gain an understanding of the business DNA and the applications that make it tick, then they can add real value to their organizations. What’s on the network vs. what should be on the network Should AppSec network engineers be expected to understand business and applications? Absolutely. With this level of skill and knowledge, they can help the business progress securely by corelating what is actually in the network environment versus what should be in the environment. Once they have clear understanding, they can clean up then environment and optimize network performance with enhanced security. This becomes more critical as organizations grow and develop, often allowing too much unnecessary traffic into the environment. Typically, this is how the scenario plays out: Applications are added or removed (decommissioned), or a new vendor or solution is brought on board and the firewall turns into a de facto router. The end result of such often leads to new vulnerabilities and too many unnecessary threat vectors. This is precisely where the aforementioned soft skills come in – an AppSec network engineer should be able to call out practices that don’t align with business goals. It’s also incumbent upon organizations to offer soft skills training to help their AppSec network engineers become more valuable to their teams. Need an application view to be effective in securing the business When firewalls become de facto routers, organizations end up relying on other areas for security. However, security needs to be aligned with the applications to prevent cyber attacks from getting onto the network and then from moving laterally across the network, should they manage to bypass the firewalls. All too often, east-west security is inadequate and therefore, AppSec network engineers need to look at network segmentation and application segmentation as part of a holistic network security strategy. The good news is that there are some great new technologies that can help with segmenting an internal network. The lesser good news is that there’s a danger in the thinking that by bolting on new tools, the problem will be solved. So often these tools are only partially deployed before the team moves onto the next “latest and the greatest” solution. When exploring new technologies, AppSec network engineers must ask themselves the following: Is there a matching use case for each solution? Will procurement of another tool lead to securing the environment or will it just be another useless “flavor of the month” tool? Irregardless, once the new technology solution is acquired, it is imperative to align the right skilful people with this technology to enable the organization to intelligently secure the whole environment before moving onto a new tool. To further hone this point, celebrating the introduction of a new firewall is superfluous if at the end of the day, it does not utilize the right rules and policies. Ushering some of these new technologies without proper deployment will only leave gaping holes and give organizations a false sense of security, exposing them to continuous risks. Don’t put the cloud native cart before the horse The role of an AppSec network engineer becomes even more critical when moving to the cloud. It starts with asking probing questions: What are the applications in the business and why are we moving them to the cloud? Is it for scalability, speed of access or to update a legacy system? Will the business benefit from the investment and the potential performance impact? It’s also important to consider the architecture in the cloud: Is it containerized, public cloud, private cloud or hybrid? Once you get definitive answers to these questions, create reference architectures and get senior level buy-in. Finally, think about the order in which the enterprise migrates applications to the cloud and maybe start with some non-critical applications that only affect a small number of locations or people before risking moving critical revenue generating applications. Don’t put the cart before the horse. DevSecOps: We should be working together; you can be sure the criminals are… Network application security is complicated enough without introducing internal squabbles over resources or sacrificing security for speed. Security teams and development teams need to work together and focus on what is best for your business. Again, this where the soft skills like teamwork, communications and project management come into play. The bottom line is this: Understand bad actors and prepare for the worst. The bad guys are just chomping at the bit, waiting for your organizations to make the next mistake. To beat them, DevSecOps teams must leverage all the resources they have available. Future promise or false sense of security? There are some exciting new technologies to look forward to in the horizon to help secure the application environment. Areas like quantum computing, machine learning, AI and blockchain show great promise in outfoxing the cyber criminals in the healthcare and financial services industries. It is expected that the AppSec network engineer will play a vital role in the viability of these new technologies. Yet, the right technology will still need to be applied to the right use case correctly and then fully deployed to in order see any effective results. The takeaway So much of the role of the AppSec network engineer is about taking a cold hard look at the goals of the business and asking some challenging questions. It all starts with “what’s right for the business?” rather than “what’s the latest technology we can get our hands on?” To be an effective AppSec network engineer, individuals should not only know the corporate network inside out, but they also must have an overall grasp of applications and the applicable business cases they support. Furthermore, collaboration with developers and operations (DevOps) becomes an agent for rapid deployment of revenue generating or mission critical applications. But it still goes back to the soft skills. To protect the business from taking needless security risks and demand a seat at the decision-making table, AppSec network engineers need to apply strong leadership, project management and communications skills To learn more on the importance of AppSec network engineers to your organization’s cybersecurity team, watch the following video Schedule a demo Related Articles Q1 at AlgoSec: What innovations and milestones defined our start to 2026?
