What is a Firewall Configuration Review?

The main purpose of a Firewall Review is to ensure the rule sets and configuration are in line with the business requirements. An important part of the review is to ascertain traffic flows, services, protocols & ports in use against the approved services required by the business.

If the required information is available*, our Firewall Reviews typically consist of the following steps;

  • Network Diagram Familiarization*
  • Information Flow Understanding
  • Identify & Confirm Approved Services, Ports & Protocols
  • Review The Current Configuration
  • Review The Rule Sets
  • Preparation of A Report on Evidence/Findings
  • Provide Remedial Advice

Edge Cyber Security use industry approved tools as well as technical knowledge to view and understand rule sets from the firewall, rule usage statistics for each rule, data on traffic allowed through the firewall and denied by the firewall. The ‘Approved List’ is also required for the rule set review. Review the use of “any” in the source, destination or port in “allow rules”. For each “allow” rule, drill down into actual traffic and determine what is talking to what on what port. Only traffic identified in the approved list is allowed to pass through the firewall. This applies to not only inbound traffic but outbound traffic as well.
