Three Steps to Effectively Segment Your PCI Environment

Published by Illumio

Protecting cardholder data in today’s dynamic data environments has never been more difficult. PCI starts with the assumption that everything in the environment is in scope, which can be a cost-prohibitive exercise because data centers and payment infrastructures are becoming increasingly more complex. 

Security segmentation can help with your PCI scoping and segmentation in three steps:

  1. Identify your PCI environment from out-of-scope system components.
  2. Define policies and program firewalls rules that segment your PCI environment from out-of-scope systems.
  3. Monitor and adapt firewall rules to maintain your PCI segmentation posture and demonstrate compliance to your auditors.

This white paper explains these steps and guides you through them, identifying the most valuable capabilities you need for each step.
