What are the roles of network segmentation in enhancing security?

Segmentation plays a crucial role in isolating and protecting different parts of a network by dividing the network into separate segments or subnetworks. Each segment can have its own security parameters, access controls, and policies, which helps in containing potential security breaches or threats within a specific area of the network. By segmenting the network, organizations can limit the spread of malware, unauthorized access, or data breaches from affecting the entire network. It also allows for easier monitoring and management of network traffic and security measures for specific segments, enhancing overall network security.
