Tap: A Tap interface monitors traffic that is connected to a network switch’s MIRROR/SPAN port. This mirrored traffic is forwarded by a switch port to a firewall’s Tap interface and is analyzed for App-ID, User-ID, Content-ID, and other traffic, just like any other normal data traffic that would pass through the firewall. Before traffic can be logged, a security policy must be configured that includes the Tap zone. Tap interfaces are easy to deploy and can be implemented without disruption to your existing network. Tap mode offers visibility in the Traffic log and also in the ACC tab. The information can be used to help configure security policy rules, and to make other firewall configuration changes. Tap traffic is not managed (blocked, allowed, or shaped) TAP interfaces must be assigned to a Tap zone.
