5.2.3 Trigger
A security trigger is used to deal with application protocols that set up separate
sessions. Some application protocols, such as NetMeeting, open the primary sessions
and secondary connections at the same time during the normal operations. The trigger
tells the security mechanism to handle these secondary sessions and instruct it how to
handle them. The trigger handles the situation dynamically, allowing the secondary
sessions only when appropriate. These newly triggered sessions are not restricted by
the firewall.
