The Fundamentals of Network Segmentation

29/01/202505/02/2025 SECITHUB

Network segmentation involves dividing a network into smaller, isolated subnetworks, each with its own security controls and policies. This segmentation can be physical, using hardware devices like routers and firewalls, or logical, using software-defined networking (SDN) techniques. Types of Network Segmentation Physical Segmentation Logical Segmentation Micro-Segmentation Identity-Based Segmentation How to Implement Effective Network Segmentation Define Objectives and Scope Begin by identifying the purpose of segmentation in your network. Common goals include protecting sensitive data, preventing lateral movement of threats, and meeting compliance requirements. Conduct a thorough risk assessment to prioritize…
