TMA-PALOALTO-8.1
Ensure 'SSL Forward Proxy Policy' for traffic destined to the Internet is configured
Description
Configure SSL Forward Proxy for all traffic destined to the Internet. In most organizations, including all categories except financial-services, government and health-and-medicine is recommended. PASS requires a decryption rule of type ssl-forward-proxy; confirm it covers internal sources to the untrusted zone with the documented category exclusions. Audited against the PAN-OS running configuration in set format: run 'set cli config-output-format set', then 'configure' and 'show' (or 'show config running') and save the full output.
