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.

The application was very useful, simple to use and made everybody happy." AlgoSec Business Impact Simplify data center migration projects Reduce rule migration process time by 80% Streamline and improve firewall operations Background A multinational pharmaceutical company, Sanofi, has 112 industrial sites in 41 countries and operations in more than 100 countries. The company’s 110,000 employees are committed to protecting health, enhancing life, providing hope and responding to the potential healthcare needs of seven billion people around the world. Challenge The sensitive nature of Sanofi’s business and its wide ranging global operations require an extensive and well secured network, which currently has 120 firewalls all over the world. In the midst of a data center consolidation project, the company needed to understand how its security devices would be affected by application migrations. Sanofi was also eager to improve change management processes and gain key performance indicators (KPIs) for risk analysis.“Our main concern with the data center consolidation project was to enable various technical project leaders to see the different rules impacting the migration of their applications, and to avoid any outages. For that, we needed pre-migration and post-migration documentation on security,” says Bruno Roulleau, Network Security Architect at Sanofi. “We also needed metrics on the risk associated with different policies on the firewalls.” Solution When looking for a solution, Sanofi evaluated several vendors. “A key point for us was the ability to easily integrate the security devices in our current infrastructure, into the solution. We also wanted detailed reporting that would allow us to delegate policy management to project leaders,” Roulleau notes.Because Sanofi constantly upgrades its devices, its systems need to evolve and incorporate the new devices and rules seamlessly. “We chose the AlgoSec Security Management solution because its graphical interface is very user-friendly, it easily supports new devices and generates detailed reports and metrics on risks,” says Roulleau.Sanofi also appreciated AlgoSec’s flexibility. “AlgoSec is very open to developing new capabilities. We can ask to have some new features available by a certain date and they will deliver on time,” according to Roulleau. For a company with a complex network and rapidly evolving security needs, that responsiveness proved key to the decision to go with AlgoSec. Results Sanofi’s security team is now able to delegate responsibility for rule changes both during migration and on an ongoing basis. “Using AlgoSec during our data center migration allowed us to give technical project leaders access to all of the rules involved in the migration of their applications, which reduced the IT security team’s time on these projects by 80%. The application was very useful, simple to use and made everybody happy,” Roulleau says.Additionally, with AlgoSec’s reports Sanofi can now easily and clearly document the status of their firewalls as well as the impact of any changes on the network throughout the migration project. “We can now generate detailed reports in just three clicks!” Roulleau adds.Furthermore, AlgoSec’s optimization reports enabled Sanofi to clean up its security policies. Because they could clearly see all of the rules and their impact on network security, Roulleau’s team was able to safely eliminate unused and duplicate rules, which increased the efficiency of the firewalls. Those reports also provided insight into the risks associated with the current system and various changes being made. Schedule time with one of our experts

Understand HIPAA network compliance requirements. Learn how to safeguard patient data with robust network security measures and ensure compliance with HIPAA regulations. HIPAA network compliance & security requirements explained What are HIPAA network compliance requirements, rules, and violations? The advancement in data management technology has revolutionized how healthcare providers offer their services. Digital or electronic solutions are integrated into healthcare processes to improve productivity, enhance efficiency, and meet patients’ demands. Before digital transformation swept across the healthcare industry, healthcare providers at all levels relied upon manual methods and traditional data processing to carry out their day-to-day activities. Today, modern solutions, like computerized physician order entry (CPOE) and electronic health records (EHR), have replaced them, streamlining repetitive tasks, encouraging collaboration, and improving data sharing. Even though using computerized systems and other medical record management systems is very helpful, the security of confidential healthcare information has been a major challenge. To ensure that the privacy and security of patients’ information are maintained, the government created a law to enforce compliance (by organizations) with security best practices. This is where HIPAA comes in! Schedule a Demo What is HIPAA compliance? This refers to compliance with regulatory standards that outline what organizations that handle protected health information (PHI) must do to ensure the privacy and security of patients’ data. The U.S. Health Insurance Portability and Accountability Act (HIPAA) requires healthcare providers and their business associates to implement physical, network, and process security measures to ensure the security of PHI. HIPAA regulations set clear standards that health organizations must meet when managing patients’ sensitive data, like patient medical records, health insurance information, and other personally identifiable information. Schedule a Demo Who needs to be HIPAA-compliant? According to the HIPAA, the Privacy Rule covers: Health plans Health care clearinghouses Healthcare providers who execute certain financial and administrative transactions electronically. Schedule a Demo What are HIPAA compliance requirements? There are some measures organizations are required to implement to protect patients’ sensitive data. If your company is a “covered entity”, it is expected to meet the following compliance requirements: 1. Have a dedicated HIPAA privacy officer There is a need for a professional who understands HIPAA and how to comply with the regulations. The officer will guide your organization on the right path and implement necessary measures to avoid HIPAA violations. And when a data breach or violation happens, the officer should restore order following the provisions of the act. 2. Identify and classify sensitive data Does your organization manage data that is not subject to HIPAA regulations? If that is the case, identify and classify sensitive information that should be handled according to HIPAA requirements. This helps you to implement security measures with little or no ambiguity. 3. Staff training Malicious actors usually target employees of organizations they want to attack. To equip your staff with the ability to spot attacks from a distance, you need to institute staff training. Your employees need to learn how to implement physical, administrative, and technical safeguards to protect PHI. 4. Institute strict data management policies Getting your staff trained on HIPAA laws and regulations is not enough. They need good leadership to uphold data security standards. Establish data management policies to enforce best practices and regulate access privileges. 5. Equip your facilities with security solutions Access control is a significant part of HIPAA compliance. Ensure unauthorized users don’t have access to computers, documents, or sensitive parts of workstations. You can achieve this by implementing security measures that regulate access to data and notify you when someone trespasses. 6. Install encryption software where necessary Data encryption solutions make files inaccessible to cybercriminals. Cloud solutions and other digital methods of storing data have increased the surface area for attacks. Malicious cyber actors are relentlessly scouring the internet for security vulnerabilities. Safeguarding patients’ data with encryption software is the way to go. 7. Enforce common best practices Visiting a malware-compromised website or clicking an ‘infected’ link can make your organization prone to a security breach. Encourage safe browsing and adopt security solutions, like email security software and antivirus systems. 8. File disposal policy Don’t dispose of documents or storage devices without rendering them unreadable. The best way to dispose of documents and records is to destroy them – by shredding or burning them. 9. Establish procedures for handling data breaches The primary goal is to prevent a security breach. However, the undesirable happens, and you need to be ready for the worst-case scenario. Establish and maintain procedures for managing security challenges. Ensure you appoint well-trained security experts who can respond swiftly when a breach occurs. 10. Monitor & review your assets & procedures regularly Keep an eye on your data assets and management policies. This helps you to identify inefficiencies and adopt measures to plug loopholes. Regular review is necessary to ensure you are keeping up with best practices. Remove outdated solutions and procedures to stay a thousand steps ahead of criminals. 11. Implement a strict backup policy Implement a backup strategy that conforms with the dictates of HIPAA. That said, having a good backup policy helps you clean up a data breach quickly. The general backup best practice is to have three copies of data at three different premises – on-site, off-site, and cloud locations. 12. Establish and maintain a disaster recovery plan A disaster recovery plan outlines how your organization will restore operations and manage stakeholders after a security breach. It details how your security team will respond to emergencies or the aftermath of security problems. Remember, your disaster recovery system should comply with the provisions of HIPAA. Schedule a Demo What are the four main HIPAA rules? The major HIPAA rules are the Privacy Rule , Security Rule , Breach Notification Rule , and Omnibus Rule . Let’s take a look at each rule. The HIPAA privacy rule The HIPAA Privacy Rule is a regulatory framework that mandates covered entities and their business associates to uphold patients’ rights to data privacy. The privacy rule states what constitutes electronically protected health information, how it should be safeguarded, and the DOs and DON’Ts of PHI management. In a nutshell, this rule establishes how patients’ sensitive information should be protected, stored, used, shared, and disclosed. Any identifiable patient data is subject to the Privacy Rule. The PHI includes: Any past, present or future documentation on physical or mental conditions Healthcare records of the patient Records showing past, present, or future healthcare payment information According to the Privacy Rule , covered entities and their business associates are responsible for protecting PHI. There are cases where organizations can disclose private health information. But such scenarios are strictly defined by the rule and subject to legal interpretation. The HIPAA security rule While the Privacy Rule defines what privacy and ePHI (electronic PHI) are, the Security Rule is a framework that outlines the standards required to ensure the security of electronically protected health information. The security rule covers every aspect of your organization’s operations, from administration and physical processes to computers and technology equipment. The security rule has five sections: general rules, administrative safeguards, physical safeguards, technical safeguards, and organizational requirements. The General Rules The General rules mandate organizations to: Protect ePHI from reasonably anticipated threats or hazards Prevent any reasonably anticipated uses or disclosures of PHI that are not in line with the provisions of the Privacy Rule Enforce compliance with the security rule by the employees The Administrative Safeguards The Administrative Safeguards require the implementation of security policies and procedures. It dictates that the Security Officer should be responsible for conducting risk analyses, staff training, adopting risks and vulnerability management measures, and other administrative measures. The Physical Safeguards The physical safeguards outline how physical access to ePHI should be regulated. Whether the ePHI is stored in the cloud, in a remote data center, or on on-premise servers, there should be a strict policy that regulates access. This section of the security rule also states how access to workstations and devices should be safeguarded. The Technical Safeguards This part of the security rules focuses on ensuring that every person accessing ePHI is legitimate and does exactly what they are supposed to do. The technical safeguards help to ensure that security challenges are identified and rectified timely. The safeguards cover access controls, audit controls, integrity controls, transmission security, and any person or entity authentication. Organizational Requirements This section states the things business associate agreements must cover. Organizational Requirements stipulate that: Business associate agreements must provide that the business associates comply with the relevant parts of the security rule. Business associates must ensure compliance with subcontractors by entering into an Agreement with them. Business associates will report any security breach to the concerned covered entity. The HIPAA breach notification rule As much as organizations strive to comply with the requirements of HIPAA, security breaches still happen. It’s difficult, if not impossible, for covered entities and business associates to protect data with 100% effectiveness. Organizations must notify the public and the data subjects about a breach and disclose the steps they are taking to contain the problem. The Breach Notification Rule outlines what covered entities need to do when a breach occurs. Organizations are required to: Notify the people affected by the breach Inform the affected people within 60 days of the discovery of the security incident Provide a public notice if more than 500 individuals are impacted And more! The HIPAA omnibus rule According to the Omnibus Rule, organizations outside of covered entities (business associates and contractors) must meet compliance obligations. This rule states that covered entities are responsible for ensuring that business associates and contractors are compliant. Consequently, covered entities have to implement compliance measures to avoid any violations. Schedule a Demo What are HIPAA violations and how to avoid them? Violation is said to have occurred when an organization fails to comply with or meet the requirements of HIPAA. There are two major categories of violations: civil and criminal violations. Civil violations are committed accidentally or without malicious intent. On the other hand, criminal violations are done with malicious intent. As expected, penalties for civil violations are less than that for criminal violations. Here are some examples of violations and tips on how to avoid them: Illegal exposure of patients’ data Disclosing patients’ data to unauthorized parties accidentally or on purpose violates HIPAA provisions. There is a guideline for disclosing sensitive healthcare information. When due process is not followed, a violation occurs. And the penalty for unlawful disclosure of medical records depends on a range of factors, including whether it’s a civil or criminal violation. To avoid this type of violation, implement strict administrative policies. Allow only a few well-trained administrators to have the privilege to access or disclose data. When data access is strictly regulated, you can easily prevent unauthorized access and keep tabs on data management. Failure to implement proper security best practices The HIPAA security rule outlines the security protocols covered entities are required to implement. Given the complexity of data protection today, it’s easy to leave important things undone. You can avoid this by appointing an experienced security officer. You should also set up a committee of security professionals responsible for ensuring the proper implementation of security protocols. Lack of a consistent training policy It takes consistent staff training to meet the requirements of HIPAA. Both old and new employees need to be trained from time to time on how to protect healthcare data. Make training an integral part of your administrative policy. Non-compliance to security regulations is mainly caused by people. No matter the type of access management or security risk mitigation software you implement, you need an informed workforce to ensure compliance. Lack of proper notification after a security breach The HIPAA breach notification rule states how healthcare service providers should notify affected data subjects and public officials after a security incident. Failure to do so accordingly results in HIPAA violation. To avoid this, appoint a HIPAA compliance officer to monitor compliance gaps and ensure that requirements are met at every point in time. In addition, your contingency plan or disaster recovery system should contain a guideline on how to notify impacted parties when things go wrong. Lack of measures to address existing compliance gaps Neglecting existing compliance gaps or not doing the needful to avoid potential security problems violates HIPAA. Healthcare organizations are expected to act proactively, leveraging risk assessment and risk management policy to protect PHI. To close compliance gaps, do the following: Establish a HIPAA compliance enforcement team and a compliance officer Keep all software updated Conduct HIPAA audits regularly Work with a health information technology and security company that offers HIPAA compliance services. Schedule a Demo How can your network become HIPAA compliant with AlgoSec? HIPAA compliance requirements can be challenging to meet.

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

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.

Microsegmentation Zero Trust: How Microsegmentation Drives Zero Trust Success Microsegmentation zero trust is the practice of enforcing zero trust principles through fine‑grained, application‑aware segmentation at the workload and service level. Companies today are turning to microsegmentation, a granular form of network segmentation, to contain attacks quickly, prove least‑privilege access, and simplify compliance across hybrid environments. Despite still having to spend an average of $4.4 million per breach, according to IBM's Cost of a Data Breach Report 2025 , this is 9% lower than 2024. That drop ties directly to faster identification and containment—outcomes microsegmentation accelerates by limiting lateral movement and shrinking the blast radius from the first indicator of compromise. In yet another study, Verizon’s 2025 Data Breach Investigations Report , more than 12,000 confirmed breaches demonstrated how multi-stage intrusions use lateral movement, which microsegmentation technology directly addresses. Meanwhile, the Payment Card Industry Data Security Standard (PCI DSS) requires network segmentation for system scope reduction, which leads to decreased audit work and better system isolation. Taken together, these findings underscore a simple point: Organizations need application‑aware controls—specifically microsegmentation—to stop attackers from moving between systems and to operationalize zero trust. This article discusses the zero trust vs. micro‑segmentation debate, explains how zero trust and microsegmentation in fact work together, and provides a path to design, enforce, and operate this approach. What Is Microsegmentation? Microsegmentation divides networks into small, secure domains that match workload requirements and user/service identities with explicit allow‑rules to stop lateral movement. Network security today benefits from application-based boundaries, i.e., policies applied where applications actually communicate—not just subnets and VLANS. In practice, that means protecting individual workloads and the communication between them across data centers, public clouds, containers, and endpoints—rather than vaguely “protecting components” or “locations.” What Is the Difference Between Traditional (Macro) and Micro-Segmentation This comparison comes down to a difference in approach: Macro-segmentation uses broad VLANs and subnets or DMZs to divide network tiers; while this provides limited east-west control, it is simpler to design. Micro-segmentation uses SDN and host agents, as well as cloud security groups; application-specific policies are enforced at the workload/service boundary, which is why they are the engine of microsegmentation zero trust. What Role Do Firewalls and Network Segmentation Layers Play in Microsegmentation? Your existing perimeter and internal firewalls provide north‑south control, compliance zones, and enforcement points that microsegmentation can orchestrate. In other words, microsegmentation complements firewalls and network segmentation layers—it does not replace them. Extending the point above: Microsegmentation orchestrates those firewall and segmentation layers to deploy least‑privilege across hybrid systems—specifically: Cloud security groups NACLs SDN fabrics Kubernetes policies Host-based controls Since these layers are complementary, they collectively shrink the blast radius. What Is Zero Trust? Zero trust is a security concept, not a product or service. The system uses identity-based dynamic authorization, which takes into account device health status and environmental context—instead of traditional static location-based access methods. Verification is continuous because environments and risk conditions evolve. Zero trust verifies every access decision—no implicit trust—and enforces least privilege Zero Trust vs. Micro‑Segmentation: Complementary Forces While zero trust operates as an operational framework, microsegmentation functions as an implementation methodology. While zero trust explains what needs protection and which aspects require protection, microsegmentation provides the how. The table below breaks down the two concepts across key parameters. Aspect Zero Trust (Strategy) Microsegmentation (Mechanism) Focus Identity, posture, continuous verification Allowed app/workload flows Scope Enterprise‑wide architecture App tiers, services, identities Enforcement Policies derived from context and risk SDN, host agents, security groups, firewalls Outcome Minimized implicit trust; provable least‑privilege Contained blast radius; fewer lateral‑movement paths What Is Microsegmentation Zero Trust? The combination of zero trust and microsegmentation forms microsegmentation zero trust—a strategy connected to enforcement. The three primary goals of this approach are: Risk reduction Lateral movement prevention Least privilege verification Microsegmentation zero trust applies zero trust principles—continuous verification and least privilege—by defining and enforcing explicit, application‑aware allow‑rules between identities, services, and workloads. Why Does Microsegmentation Zero Trust Matter? It matters because it measurably reduces lateral movement paths and speeds incident containment. Authorized paths are explicitly permitted communication flows (service A to service B on port X from an approved identity) that have been validated as necessary for the application to function. Pre‑defining and testing these authorized paths speeds deployment because changes ship with pre-validated, least‑privilege policies—reducing last‑minute firewall rework, minimizing approvals, and preventing rollback from unexpected blocks. Implementing Microsegmentation to Achieve Zero Trust Microsegmentation is a continuous process, consisting of multiple stages to successfully achieve zero trust. Asset & Dependency Discovery Start by analyzing the network traffic behavior of applications and workloads in traditional on-premises setups, public clouds, and container environments. This application-first view serves as the base for zero trust segmentation, which stops security gaps from occurring. Policy Creation Create allow‑lists for individual app components and identity groups based on observed application traffic flows (sources/destinations, ports, processes) and documented business requirements, then validate with “what‑if” simulations before production. Enforcement Implement the approved policy through current controls—cloud security groups, firewalls, SDN fabrics, host controls, and Kubernetes—to achieve uniform protection across hybrid and multi-cloud systems. Continuous Monitoring & Adaptive Policy Continuously monitor for drift, prune unused rules, and adjust policies using detection data—without re‑introducing broad implicit trust or “allow any” access. Challenges & Pitfalls to Avoid Security organizations that operate effectively still encounter various obstacles when implementing microsegmentation: Lack of visibility in application maps: When third-party or SaaS endpoints and ephemeral services (containers, serverless functions) are not properly documented, visibility suffers. The fix? Run continuous dependency discovery operations while keeping tags and labels up to date. Focusing solely on network-based controls: Ignoring workload and identity context can weaken your security measures. The fix? Use service accounts, workload identities, namespaces, and labels as the basis for policy connections whenever possible. Relying on a single technology: Depending only on firewalls or security groups can create gaps in your security posture. The fix? Implement security orchestration using a combination of firewalls, SDN security groups, and Kubernetes network policies. Manual exception handling: Human intervention creates delays, slowing down release cycles. The fix? Orchestrate a combination of controls—next‑gen firewalls, SDN fabrics, cloud security groups, and Kubernetes network policy—so each layer covers the others.
