      I'm running Suricata on LAN in detection mode (no blocking). I disabled the pre-defined Snort IPS policies and selected a small subset of rules to get started. I did NOT enable emerging-policy.rules. However, I am getting:

      Potential Corporate Privacy Violation
      1:2000419 ET POLICY PE EXE or DLL Windows file download
      

      I went to SuricataInterface LANRules: decoder-events.rules and scrolled through the "Categories". I can't find any ET POLICY rules.

      Why is Suricata issuing a policy rule alert when emerging-policy.rules is not included as a selected ruleset (or found in the Categories list)?

      Services / Suricata / Global Settings
      ETOpen Emerging Threats Rules
      Install Snort VRT Rules
      Install Snort Community rules

      Suricata IDS / Interface LAN - Categories
      Resolve Flowbits enabled
      Not using pre-defined Snort IPS policies
      Selected rulesets:
      Snort GPLv2 Community Rules
      A few of the Snort Text Rules (i.e. malware)
      A few of the ET Rules (i.e. malware, botcc)

        Solved.

        The ET POLICY rules are in the Resolve Flowbits automatic rules.

        However, you can't view the rules in the Suricata Interface LANRules: decoder-events.rules page. You have to view them on the Suricata IDS / Interface LAN - Categories page.
