Overview: Firewall rules that provide access to a wide array of services in a large network, while at the same time securing the critical assets from attacks, tend to become very large in size and redundant in functionality. As rule bases become large, administrators become hesitant to modify existing rules and instead add new rules for fear of causing an adverse impact on existing service availability. Over time, rule bases become very bloated, requiring not only more effort in making changes but also having an adverse impact on the firewall performance. It is therefore essential to clean up the rule base and reduce its size. This paper presents some techniques to cleaning up the rule base along with an effective solution that addresses these automatically for you using Athena FirePAC for Firewall Rule Cleanup.
