Network segmentation divides networks into smaller zones, limiting lateral movement and containing potential breaches.
What is Segmentation?
Dividing a network into segments with access controls between them, preventing unrestricted east-west traffic.
Benefits
- Breach Containment - Limit spread of compromises.
- Compliance - Isolate regulated data.
- Performance - Reduce broadcast traffic.
Implementation
Use VLANs, firewalls, and access controls to create and enforce network boundaries.
Segment Security
Apply IP filtering at segment boundaries.
