Best Microsegmentation Solutions

When beginning the process of moving to a microsegmentation solution, it is important to be vigilant and painstakingly thorough to ensure that nothing is missed in the process and to avoid any avoidable issues.

1. Know your traffic - Microsegmentation is complete transparency of ALL traffic flow - north-south and east-west. You will need to work with your IT team and perhaps look at third-party solutions to get a complete understanding of the current appropriate ongoing communication and active productive connections between workloads. This will facilitate the identification of unnecessary connections which need to be closed.

1. Identify your segments - Next, you will want to identify your segments. The most common ones are function, location, class, security threat, and distinction. These identifiers will help with regulating communication flows throughout your workflows. These identifiers or tags will help when adding third-party solutions and scalability. They will also play a big part with increased security options as you make changes to your plan.

1. Establish concise security protocols - You will want to identify the level of threat risk that is unique to your organization and the microsegmentation attributes you have created. These protocols should be extremely thorough and address every type of communication flow and every device with access to your network and how they will all relate to each other. You will want to take a deep dive into your entire ecosystem to ensure every workflow has been considered. The zero-trust concept must be applied and all traffic must be identified, categorized, and verified to securely reduce the chance of any threat to your organization. Within the zero-trust concept, any unknowns must be denied access and considered a potential threat risk.

1. Scalability is a must - Organizations are growing and changing - sometimes, daily. You need to create the option to make adjustments and adapt to changes as your organization changes. Complete workflow transparency allows for immediate identification of changes in workflow and complete awareness of any changes to the threat surface. You will want your system to be able to identify new workloads and auto-tag them with known identifiers.

1. Implement your plan - Start slow. You want to roll out your plan slowly and with solid communication to all members of your project team, (security, tech, architect, etc). It’s best to start small, test your plan, gain feedback, test again, then add new workloads to your rollout plan. During every step in your rollout process, you want to ensure protocols are workable and being followed consistently. If any problems develop, it is important to address them immediately and make the necessary adjustments to your plan, communicate the changes to the team, and continue to the next segment based on your set priorities. Once the entire rollout is complete, continue to regularly follow up to make certain all protocols are being satisfied and everything is working according to plan.

Microsegmentation Software enhances network security by dividing your data center into smaller segments, each capable of having its own security policies. This approach minimizes the attack surface by ensuring that potential threats are contained within a single segment. You can apply strict controls to each segment, making unauthorized access more difficult and isolating threats to prevent lateral movement across your network.

Implementing Microsegmentation Software offers several benefits, including improved breach isolation, enhanced visibility of traffic flows, and optimized security controls. You can tailor security policies to fit individual workloads, allowing for a more custom and precise security posture. This leads to greater operational efficiency and reduced risk of widespread breaches, offering a significant upgrade from traditional perimeter defenses.

Microsegmentation helps with compliance by providing granular control over data flow and access. With Microsegmentation Software, you can enforce strict compliance with regulations like GDPR and HIPAA by tightly controlling data access and maintaining detailed logs of traffic patterns. This control ensures that sensitive information remains protected and auditable, helping you meet industry standards and legal requirements.

Microsegmentation is critical in a Zero Trust architecture because it aligns with the principle of least privilege, a core tenet of Zero Trust. By dividing your network into microsegments, you can enforce strict, identity-based access controls. Each segment acts as a security boundary, requiring verification of each entity's identity before access is granted. This setup is essential in maintaining strong security postures and preventing unauthorized access.

Deploying Microsegmentation Software can present challenges such as complexity in initial setup and integration with existing IT infrastructure. You may also face challenges related to maintaining performance levels while applying security measures. It requires a clear understanding of your network's architecture and traffic patterns to implement effectively, potential adjustments to workflows and processes, and possibly substantial initial time investments. Adequate planning and resources are necessary to overcome these challenges effectively.
