Network Security Tip of the Week [3] – Firewall Change Management

This week’s network security tip is around a theme we’ve been examining over the past few weeks: firewall change management. This tip from Pedro, an engineer in Portugal, is fundamental, but oftentimes it’s forgotten/not done properly.

“Keep a historical change log of your firewall policy, so you can return to safe harbor in case something goes wrong. A proper change log should include the reason for the change, the requester and approval records. These logs also help keep track of all changes made and why they have occurred.”
