Without strong network segmentation policy and security measures, if a server firewall gets breached, the attacker can move easily to any number of others in the network. Perimeter security measures like firewalls – even if virtualized – do not prevent attackers as they expand their foothold using east-west traffic.
The most effective way to limit connectivity between servers is by segmenting the network. There are three basic types of network segmentation, with micro-segmentation being the best to enforce increasingly granular policy and control.
This guide uncovers the differences in methods and how the right micro-segmentation techniques most efficiently address the shortcomings of other alternative network segmentation approaches.
