Symptom


This document describes how to identify the unused security policies on a Palo Alto Networks device.



Environment


  • PAN-OS 7.1 and above.
  • Palo Alto Firewall.


Resolution


To view the unused rules on the Web UI:

  1. Navigate to Policies > Security
  2. Check Highlight Unused Rules at the bottom of the page
Highlight Unused Rules
 
  • Any rules not used since the dataplane started up will be highlighted.
  • The counters for unused rules are initialized when the dataplane boots, and they are cleared anytime the dataplane restarts.

 

To verify if these rules have been used, look at a pre-defined report called Security Policies. This report will show the rule, bytes and the amount of sessions.

  1. Go to Monitor > Reports.
  2. On the right side of the display, select Traffic Reports > Security Rules.
  3. Select the day for which to run the report for.
  4. Click on Export to PDF (or csv / xml)

CLI commands for different PAN-OS listed below:
