Network Segmentation

About

Network segmentation is a crucial architectural approach in network security that involves dividing a larger network into smaller, isolated segments or subnets. Each segment functions as a separate entity with its own set of security controls and policies, limiting the ability of threats to move laterally within the network. This strategy enhances security by isolating network traffic, reducing the attack surface, and preventing the spread of malware. By segmenting the network, organizations can control access to sensitive resources and protect critical data. Segmentation also improves network performance by reducing congestion and simplifies management by allowing tailored security measures for each segment. It aids in regulatory compliance by isolating sensitive data and limiting the scope of compliance requirements. Network segmentation can be implemented through physical or virtual methods, using devices like firewalls, switches, and routers to manage traffic flow between segments. This approach ensures that even if one segment is compromised, the rest of the network remains secure, maintaining business continuity and protecting sensitive information.
