Network Segmentation - Isolating Network Segments To Enhance Security & Performance

Network segmentation is a crucial cybersecurity practice that divides a network into smaller, isolated segments to enhance security and performance. This reduces the impact of breaches by limiting the spread of attacks and improves network visibility. Zero-Trust Network Access (ZTNA) complements network segmentation, acting as a primary defense by verifying access based on policies rather than trust. Best practices involve careful user access control, isolated guest networks, segregation of IoT devices and third-party vendors, and regular network audits. The overall goal is to mitigate the growing threat of cyberattacks and protect sensitive data.
