Ensure that 'Wildfire Inline ML Action' on antivirus profiles are set to reset-both on all decoders except 'imap' and 'pop3'

HighLevel 1Automatedpaloalto

Description

Configure 'Wildfire Inline ML Action' on antivirus profiles to a value of 'reset-both' for all decoders except imap and pop3 under 'Wildfire Inline ML Action'. If required by the organization's email implementation, configure imap and pop3 decoders to 'alert' under 'Wildfire Inline ML Action'. FAILs if any antivirus profile sets the WildFire Inline ML action (mlav-action) on ftp, http, http2, smb or smtp to anything other than reset-both. 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.
