Secure Network Design: Micro Segmentation

by Brandon Peterson Sept. 1, 2017 via SANS Institute

Hackers, once on to a network, often go undetected as they freely move from system to system looking for valuable information to steal. Credentials, intellectual property, and personal information are all at risk. It is generally accepted that the attacker has the upper hand and can eventually penetrate most networks. A secure network design that focuses on micro segmentation can slow the rate at which an attacker moves through a network and provide more opportunities for detecting that movement. Organizations that implement a secure network design will find that the added cost and complexity of micro segmentation is more than offset by a reduction in the number and severity of incidents. In fact, the effort extended in learning, classifying, and segmenting the network adds value and strengthens all of the organization’s controls.
