Actions in Security Profiles

The action specifies how the firewall responds to a threat event. Every threat or virus signature that is defined by Palo Alto Networks includes a default action, which is typically either set to Alert, which informs you using the option you have enabled for notification, or to Reset Both, which resets both sides of the connection. However, you can define or override the action on the firewall. The following actions are applicable when defining Antivirus profiles, Anti-Spyware profiles, Vulnerability Protection profiles, custom spyware objects, custom vulnerability objects, or DoS Protection profiles.
