Episode 58: Network Segmentation and Microsegmentation

Segmentation limits the spread of attacks and improves control over traffic flows within a network. In this episode, we examine both traditional network segmentation and microsegmentation techniques. You’ll learn how VLANs, firewalls, and subnetting create macro boundaries, while software-defined networking enables granular control over traffic between workloads and devices. We discuss how segmentation supports least privilege access, improves detection, and reduces risk. CISSPs must know how to design segmented architectures that balance performance, visibility, and security.
