Network Segmentation.

Enterprise networks are increasingly fragmented with firewalls from different vendors, public clouds, private clouds and microservices in containers. So, how do you protect the network in the face of growing cyberthreats?

Network segmentation is a best practice to ensure the safety of your network assets by separating the systems containing sensitive information from those that do not. The idea is to limit risk and damage to a network, should an attacker be able to gain access.

While not a new practice, it is a tried and true method to ensure that if a hacker is inside they are unable to traverse the network. In fact, the Department of Homeland Security (DHS) says that network segmentation is a necessary step in an organization’s network security strategy.

A well-defined network segmentation based on your network security policy zones ensures that you are protecting against hackers from traversing your internal network. To properly segment your network, it’s a foundational requirement to know and understand who can talk to whom and what can talk to what.
