Microsegmentation
Microsegmentation definition
Microsegmentation is a technique employed by organizations to enhance their security measures. It involves dividing a network into smaller sections called microsegments, each having its security zone and specific access controls. This approach strengthens network protection by creating multiple defense perimeters instead of relying on a single one.
In microsegmentation, organizations define each microsegment based on applications, workloads, or user groups. This allows them to establish strict access controls between segments, limiting the spread of threats and reducing areas vulnerable to attacks. Even if an attacker gains access to one segment, they will encounter significant obstacles when trying to reach other parts of the network.
Furthermore, microsegmentation offers better visibility and control over network traffic. It enables organizations to monitor and manage communication within each microsegment more effectively, detecting and responding to anomalies and potential threats. This level of segmentation also facilitates the implementation of security policies and compliance measures that are tailored to specific microsegments rather than applying a uniform approach to the entire network.

Microsegmentation application
- Network segmentation. It divides the network into isolated segments, each with its IP address range and network security policies.
- Data segmentation. It divides data into isolated segments with separate access control policies.
- Application segmentation. It divides applications into isolated segments, each with its application security policies.
