Firewall Do’s and Don’ts

A firewall you set once is a firewall you forgot

The Ascend Technologies firewall guide covers the configuration and management choices that decide whether a firewall protects the network or just sits on it, including rule hygiene, logging, and change management. It is written for IT teams that inherited a firewall and are not sure it is doing its job. Teaser: A firewall is only as good as the rules behind it. This guide covers what to do and what to avoid when configuring and maintaining one, from rule review and logging to the change control that keeps it current.

How should a business configure and maintain its firewall?

Ascend Technologies recommends tight rule sets, active logging, regular rule review, and documented change control. The guide separates the practices that protect the network from the habits that quietly weaken it.
