A crucial approach to network security involves dividing a network into granular segments, restricting lateral movement and limiting the impact of potential breaches. This involves creating isolated environments for individual applications and workloads, thereby containing threats and preventing them from spreading across the entire infrastructure. The goal is to minimize the attack surface and enhance overall security posture.
The implementation of this strategy offers several key advantages. It significantly reduces the blast radius of security incidents, preventing widespread damage. Furthermore, it facilitates compliance with various regulatory requirements by providing enhanced control over sensitive data. Historically, broad network perimeters offered limited protection against sophisticated threats; this evolved security approach directly addresses these shortcomings by focusing on internal network segmentation.
