Tags Share this article 4/13/22 Published Prof. Avishai Wool, AlgoSec co-founder and CTO, stresses the importance of getting the often-overlooked function of managing network objects right, particularly in hybrid or multi-vendor environments Using network traffic filtering solutions from multiple vendors makes network object management much more challenging. Each vendor has its own management platform, which often forces network security admins to define objects multiple times, resulting in a counter effect. First and foremost, this can be an inefficient use of valuable resources from a workload bottlenecking perspective. Secondly, it creates a lack of naming consistency and introduces a myriad of unexpected errors, leading to security flaws and connectivity problems. This can be particularly applicable when a new change request is made. With these unique challenges at play, it begs the question: Are businesses doing enough to ensure their network objects are synchronized in both legacy and greenfield environments? What is network object management? At its most basic, the management of network objects refers to how we name and define “objects” within a network. These objects can be servers, IP addresses, or groups of simpler objects. Since these objects are subsequently used in network security policies, it is imperative to simultaneously apply a given rule to an object or object group. On its own, that’s a relatively straightforward method of organizing the security policy. But over time, as organizations reach scale, they often end up with large quantities of network objects in the tens of thousands, which typically lead to critical mistakes. Hybrid or multi-vendor networks Let’s take name duplication as an example. Duplication on its own is bad enough due to the wasted resource, but what’s worse is when two copies of the same name have two distinctly different definitions. Let’s say we have a group of database servers in Environment X containing three IP addresses. This group is allocated a name, say “DBs”. That name is then used to define a group of database servers in Environment Y containing only two IP addresses because someone forgot to add in the third. In this example, the security policy rule using the name DBs would look absolutely fine to even a well-trained eye, because the names and definitions it contained would seem identical. But the problem lies in what appears below the surface: one of these groups would only apply to two IP addresses rather than three. As in this case, minor discrepancies are commonplace and can quickly spiral into more significant security issues if not dealt with in the utmost time-sensitive manner. It’s important to remember that accuracy is the name in this game. If a business is 100% accurate in the way it handles network object management, then it has the potential to be 100% efficient. The Bottom Line The security and efficiency of hybrid multi-vendor environments depend on an organization’s digital hygiene and network housekeeping. The naming and management of network objects aren’t particularly glamorous tasks. Having said that, everything from compliance and automation to security and scalability will be far more seamless and risk averse if taken care of correctly.

Tags Share this article 11/27/20 Published With the rapid proliferation of cloud computing, lean deployment methods, such as containers, have become common practice. According to CIO.com, 70% of global companies are expected to be running multiple apps simultaneously using a containerized framework, like Kubernetes in the next few years. But as Kubernetes’ use becomes more widespread, so do the vulnerabilities inherent to containerization. According to a 2019 Forbes article , Kubernetes had at least 7,000 identified vulnerabilities at the beginning of 2019 alone. Couple that with the fact that cyber-attacks involving containerization have increased a whopping 240% since 2018, and you’ll understand the value of security should your company use a solution like Kubernetes to handle its container orchestration. What Causes Kubernetes Security Blindspots? To understand how to best optimize your Kubernetes experience, it’s worthwhile to understand the basic ways security issues arise in a containerized framework. Images are the core building blocks of containerization; they are the executable process at the centre of your container. As a result, anything that exposes an image to a broader audience puts the container at risk of being hijacked. One of the primary ways this occurs is by using out-of-date software. Using old software gives malicious actors a small incongruence that they can exploit within the code. Another problem is poorly defined user access roles. If sensible changes aren’t made to an orchestration tool’s default settings, inappropriate parties may have access to alter the container’s core executable. Containerization gives you a way to manage a large number of processes easily and with increased adaptability. As a result, automation makes it impossible to keep your eyes on everything at once. Here are some best practices that can help you counter the wide range of vulnerabilities inherent to containerization and Kubernetes in general. Kubernetes Security Best Practices Given the architecture of the Kubernetes framework, security risks are a constant and evolving threat. Luckily, Google made Kubernetes an open-source application under the auspices of the Cloud Native Computing Foundation where solutions to new security issues are actively crowdsourced by the community. Regardless, there are a number of things that you can do during the build, deployment, and runtime phases to make your Kubernetes implementation more secure. Take care of your images Images are the heart of every container. Executable functions are essential, so images must be well-maintained and in good working order. Only use up-to-date images, scanning them regularly for security issues. As a rule of thumb, you should also avoid including unnecessary tools and functions in your image coding as they can inadvertently give hackers an access route. Ensure that your secrets remain secret The term “secrets” refers to any private information such as login credentials, tokens, or other sensitive data. While it’s not customary to keep sensitive data stored adjacent to the container’s image, the scenario has come up before. Keep secret data as far from the image as possible in order to increase security. Keep up-to-date with scans and security patches The community does a good job of patching Kubernetes when issues arise. If you don’t take the time to update both your OS and Kubernetes’ security, you give malware additional avenues of attack. Updates should be performed at least every nine months, if not more often. Due to the nature of how Kubernetes works, if you are using an outdated version, you could actively be spreading issues when the container is deployed elsewhere. Take advantage of customization to define user roles and access A container orchestration tool like Kubernetes is a complex web running thousands of processes across numerous machines. That means hundreds of end-users involved with the application. Take advantage of Kubernetes administrative functions to clearly define user roles, limiting full access for those who don’t need it. As they say, too many cooks spoil the broth. Keeping Kubernetes Simple and Safe Containers are an agile, lightweight framework for cloud computing, but manually deploying the correct containers to their destinations can quickly become overwhelming. An orchestration tool like Kubernetes is the perfect solution to managing your containerization, but the security risks inherent to this model can be restrictive. By keeping a few key practices in mind when implementing Kubernetes into your workflow, you can help to promote safety while streamlining your processes. To Sum It All Up Kubernetes has become the centrepiece of the cloud Native landscape and a notable advantage for organizations to rapidly manage and deploy their containerized business logic. But certain security best practices must be followed such as working with reliable docker images, properly defined resource quotas, network policies, work with namespaces for access control and authentication\authorization, and more.

Network Security Policy Management Network Change Management: Best Practices for 2024 Tsippi Dach 2 min read Tsippi Dach Short bio about author here Lorem ipsum dolor sit amet consectetur. Vitae donec tincidunt elementum quam laoreet duis sit enim. Duis mattis velit sit leo diam. Tags Share this article 2/8/24 Published What is network change management? Network Change Management (NCM) is the process of planning, testing, and approving changes to a network infrastructure. The goal is to minimize network disruptions by following standardized procedures for controlled network changes. NCM, or network configuration and change management (NCCM), is all about staying connected and keeping things in check. When done the right way, it lets IT teams seamlessly roll out and track change requests, and boost the network’s overall performance and safety. There are 2 main approaches to implementing NCM: manual and automated. Manual NCM is a popular choice that’s usually complex and time-consuming. A poor implementation may yield faulty or insecure configurations causing disruptions or potential noncompliance. These setbacks can cause application outages and ultimately need extra work to resolve. Fortunately, specialized solutions like the AlgoSec platform and its FireFlow solution exist to address these concerns. With inbuilt intelligent automation, these solutions make NCM easier as they cut out errors and rework usually tied to manual NCM. The network change management process The network change management process is a structured approach that organizations use to manage and implement changes to their network infrastructure. When networks are complex with many interdependent systems and components, change needs to be managed carefully to avoid unintended impacts. A systematic NCM process is essential to make the required changes promptly, minimize risks associated with network modifications, ensure compliance, and maintain network stability. The most effective NCM process leverages an automated NCM solution like the intelligent automation provided by the AlgoSec platform to streamline effort, reduce the risks of redundant changes, and curtail network outages and downtime. The key steps involved in the network change management process are: Step 1: Security policy development and documentation Creating a comprehensive set of security policies involves identifying the organization’s specific security requirements, relevant regulations, and industry best practices. These policies and procedures help establish baseline configurations for network devices. They govern how network changes should be performed – from authorization to execution and management. They also document who is responsible for what, how critical systems and information are protected, and how backups are planned. In this way, they address various aspects of network security and integrity, such as access control , encryption, incident response, and vulnerability management. Step 2: Change the request A formal change request process streamlines how network changes are requested and approved. Every proposed change is clearly documented, preventing the implementation of ad-hoc or unauthorized changes. Using an automated tool ensures that every change complies with the regulatory standards relevant to the organization, such as HIPAA, PCI-DSS, NIST FISMA, etc. This tool should be able to send automated notifications to relevant stakeholders, such as the Change Advisory Board (CAB), who are required to validate and approve normal and emergency changes (see below). Step 3: Change Implementation Standard changes – those implemented using a predetermined process, need no validation or testing as they’re already deemed low- or no-risk. Examples include installing a printer or replacing a user’s laptop. These changes can be easily managed, ensuring a smooth transition with minimal disruption to daily operations. On the other hand, normal and emergency changes require testing and validation, as they pose a more significant risk if not implemented correctly. Normal changes, such as adding a new server or migrating from on-premises to the cloud, entail careful planning and execution. Emergency changes address urgent issues that could introduce risks if not resolved promptly, like failing to install security patches or software upgrades, which may leave networks vulnerable to zero-day exploits and cyberattacks. Testing uncovers these potential risks, such as network downtime or new vulnerabilities that increase the likelihood of a malware attack. Automated network change management (NCM) solutions streamline simple changes, saving time and effort. For instance, AlgoSec’s firewall policy cleanup solution optimizes changes related to firewall policies, enhancing efficiency. Documenting all implemented changes is vital, as it maintains accountability and service level agreements (SLAs) while providing an audit trail for optimization purposes. The documentation should outline the implementation process, identified risks, and recommended mitigation steps. Network teams must establish monitoring systems to continuously review performance and flag potential issues during change implementation. They must also set up automated configuration backups for devices like routers and firewalls ensuring that organizations can recover from change errors and avoid expensive downtime. Step 4: Troubleshooting and rollbacks Rollback procedures are important because they provide a way to restore the network to its original state (or the last known “good” configuration) if the proposed change could introduce additional risk into the network or deteriorate network performance. Some automated tools include ready-to-use templates to simplify configuration changes and rollbacks. The best platforms use a tested change approval process that enables organizations to avoid bad, invalid, or risky configuration changes before they can be deployed. Troubleshooting is also part of the NCM process. Teams must be trained in identifying and resolving network issues as they emerge, and in managing any incidents that may result from an implemented change. They must also know how to roll back changes using both automated and manual methods. Step 5: Network automation and integration Automated network change management (NCM) solutions streamline and automate key aspects of the change process, such as risk analysis, implementation, validation, and auditing. These automated solutions prevent redundant or unauthorized changes, ensuring compliance with applicable regulations before deployment. Multi-vendor configuration management tools eliminate the guesswork in network configuration and change management. They empower IT or network change management teams to: Set real-time alerts to track and monitor every change Detect and prevent unauthorized, rogue, and potentially dangerous changes Document all changes, aiding in SLA tracking and maintaining accountability Provide a comprehensive audit trail for auditors Execute automatic backups after every configuration change Communicate changes to all relevant stakeholders in a common “language” Roll back undesirable changes as needed AlgoSec’s NCM platform can also be integrated with IT service management (ITSM) and ticketing systems to improve communication and collaboration between various teams such as IT operations and admins. Infrastructure as code (IaC) offers another way to automate network change management. IaC enables organizations to “codify” their configuration specifications in config files. These configuration templates make it easy to provision, distribute, and manage the network infrastructure while preventing ad-hoc, undocumented, or risky changes. Risks associated with network change management Network change management is a necessary aspect of network configuration management. However, it also introduces several risks that organizations should be aware of. Network downtime The primary goal of any change to the network should be to avoid unnecessary downtime. Whenever these network changes fail or throw errors, there’s a high chance of network downtime or general performance. Depending on how long the outage lasts, it usually results in users losing productive time and loss of significant revenue and reputation for the organization. IT service providers may also have to monitor and address potential issues, such as IP address conflicts, firmware upgrades, and device lifecycle management. Human errors Manual configuration changes introduce human errors that can result in improper or insecure device configurations. These errors are particularly prevalent in complex or large-scale changes and can increase the risk of unauthorized or rogue changes. Security issues Manual network change processes may lead to outdated policies and rulesets, heightening the likelihood of security concerns. These issues expose organizations to significant threats and can cause inconsistent network changes and integration problems that introduce additional security risks. A lack of systematic NCM processes can further increase the risk of security breaches due to weak change control and insufficient oversight of configuration files, potentially allowing rogue changes and exposing organizations to various cyberattacks. Compliance issues Poor NCM processes and controls increase the risk of non-compliance with regulatory requirements. This can potentially result in hefty financial penalties and legal liabilities that may affect the organization’s bottom line, reputation, and customer relationships. Rollback failures and backup issues Manual rollbacks can be time-consuming and cumbersome, preventing network teams from focusing on higher-value tasks. Additionally, a failure to execute rollbacks properly can lead to prolonged network downtime. It can also lead to unforeseen issues like security flaws and exploits. For network change management to be effective, it’s vital to set up automated backups of network configurations to prevent data loss, prolonged downtime, and slow recovery from outages. Troubleshooting issues Inconsistent or incorrect configuration baselines can complicate troubleshooting efforts. These wrong baselines increase the chances of human error, which leads to incorrect configurations and introduces security vulnerabilities into the network.
