Question


Why does SSH traffic not match a security or decryption policy with a URL category



Environment


  • Palo Alto Networks Firewalls
  • Supported PAN-OS
  • URL category in security or decryption policy rule
  • SSH traffic


Answer


  1. When using TLS or HTTP a URL is referenced in the relevant traffic.
  2. The URL information is found in theĀ  client hello or server certificate for TLS, and the GET for HTTP.
  3. With SSH there is no reference to the URL and therefore it has no means to match to a URL or URL category.
