The provided images show a Log Forwarding Profile configuration. The "Alert - Threats" match list entry is configured to trigger on any threat log, as indicated by the filter (threat neq no). The action specified for this trigger is "Tagging". The details of the tagging action show that the "Source Address" of the traffic generating the log will be registered with the tag "BadGuys" for a "Timeout" of 180 minutes. This configuration does not block traffic directly; it applies a tag that can be used by a Dynamic Address Group in a separate security policy.

A. The source address of SMTP traffic that matches a threat is automatically blocked as BadGuys for 180 minutes.

The configured action is "Tagging," not "Block IP." Also, the filter is for any threat, not specifically for SMTP traffic.

B. The source address of traffic that matches a threat is automatically blocked as BadGuys for 180 minutes.

The action is "Tagging," which registers an IP address with a tag. It is not a "Block IP" action, which would actively block the source.

D. The source address of SMTP traffic that matches a threat is automatically tagged as BadGuys for 180 minutes.

This is less precise. The filter (threat neq no) applies to any traffic that generates a threat log, not just SMTP traffic.

2. Palo Alto Networks PAN-OS® Administrator’s Guide 11.0: "Use Dynamic Address Groups to Enforce Policy on Traffic from Tagged IP Addresses > Register IP Addresses and Tags Dynamically". This section describes the "Tagging" action within a Log Forwarding profile. It explains: "Select Tagging and then Add a tag to register IP addresses with a tag that you can then use as a match criterion in a Dynamic Address Group... For each tag

you can set a Timeout (in minutes) after which the tag expires." This confirms the action is tagging

not blocking.

3. Palo Alto Networks PAN-OS® Administrator’s Guide 11.0: "Monitor > Log Viewer > Log Types > Threat". This section describes the Threat log

which is generated when traffic matches a security profile (Antivirus

Anti-Spyware

etc.). The filter (threat neq no) specifically targets these logs.
