Network segmentation is a fundamental strategy for limiting lateral threat movement and protecting critical assets.
What is network segmentation?
It consists of dividing the network into smaller, isolated segments, each with its own security policies and access controls.
Benefits of segmentation
- Threat containment: Limits incident impact
- Better performance: Reduces broadcast traffic
- Compliance: Facilitates regulatory compliance
- Visibility: Improves traffic monitoring
Implementation with VLANs
VLANs (Virtual LANs) allow creating logical segments within the same physical infrastructure, separating departments, IoT devices, and critical servers.
Zero Trust and Microsegmentation
The Zero Trust approach takes segmentation to the extreme, treating each workload as an individual segment, verifying each access regardless of origin.
