Step #4 – Remove shadowed and redundant rules

Efficiency is always the goal of IT security efforts, so it is important to make sure our firewall rules aren't duplicating efforts – remove shadowed and redundant rules. 

First let's start with terminology clarification:

  • Shadowed rules – broad rule is completely eclipsing a narrowly written rule further down the rule chain.
  • Redundant rules – rules that are unnecessarily duplicated. 

Shadowed and redundant rules can leave other critical rules unimplemented and impair firewall performance. You can identify shadowed and redundant rules with a logical analysis of the firewall's access rules.

Beach season is officially here! If you want to spend more time this summer paying attention to the barbeque than your firewalls – then it's time to get your firewalls in shape! A bloated firewall rule set will slow down firewall performance and hide security issues, making it difficult to track down access violations and availability issues. That means more risk that you'll spend Saturday in the data center instead of manning the grill.

It might be too late to obtain six-pack abs before hitting the beach, but these six simple steps, provided by Skybox Security, will help guarantee you can relax this summer without worrying about your firewall.
