How to deploy on Cortex XDR

  1. 1.Paste the XQL into Incident Response > Investigation > Query Builder > XQL Search.
  2. 2.To alert, save it as a Correlation Rule and set the MITRE tactic and technique printed with the rule.
  3. 3.Schedule it on the interval you hunt at; keep the fields stage for the alert's columns.

Check · CVE rules read PAN-OS URL logs (panw_ngfw_url_raw), which need the NGFW integration and, for HTTPS, decryption.
