Review Scope and Inspection Details

• Review period documented
  Record the start and end dates for the recertification cycle.
• Firewall device, cluster, or policy package identified
  Identify the firewall platform and the specific policy scope reviewed.
• Rule population and sample size recorded
  Enter the total number of rules in scope and the number reviewed.
• Review performed against current approved baseline
  Confirm the review used the current approved firewall policy baseline or export.

Rule Ownership and Business Justification

• Rule owner assigned and current
  Confirm each reviewed rule has a named business or technical owner.
• Business justification documented and still valid
  Verify the rule still supports an active business process, application, or approved exception.
• Approver identity and approval date recorded
  Capture the approver name or role and the date of approval for the rule or rule set.
• Rule expiration or review date present where required
  Confirm temporary or exception-based rules have a defined expiration or next review date.
• Change ticket or request reference linked
  Record the change request, ticket, or exception reference supporting the rule.
• Unowned or unjustified rules identified
  Flag whether any reviewed rules lacked ownership or a valid business justification.

Rule Necessity and Stale Entry Review

• Unused source or destination objects identified
  Determine whether any rules reference objects, hosts, or services that are no longer in use.
• Duplicate or overlapping rules identified
  Check for duplicate, shadowed, or overlapping rules that can be merged or removed.
• Expired temporary rules removed or queued for removal
  Confirm expired temporary access rules are removed or placed into approved remediation.

  Select the disposition for identified stale or unnecessary rules.

Access Exposure and Security Risk

  Confirm inbound rules are restricted to approved source networks, hosts, or geographies where applicable.
• Ports and protocols match documented service requirement
  Verify the allowed ports and protocols are no broader than the documented application requirement.
• High-risk or any-to-any rules identified
  Check for overly permissive rules such as any source, any destination, or broad service access.
• Logging and monitoring enabled for required rules
