Some intrusions may target security weaknesses in specific application protocols. Therefore, some security rules are focused on special protocols on standard and frequently used ports.
If an application is available from the Internet and uses any of the listed protocols on a non-standard port, this port needs to be added to the list of ports on which protocol-specific intrusions are detected.
- In Kerio Control's Administration interface, navigate to Configuration > Intrusion Prevention.
- Click on Advanced.
- In the Advanced Intrusion Prevention Settings dialog, choose the desired service.
- Double-click the chosen row and add the port.
- Click OK and Apply.
The service running on the non-standard port is now protected by the protocol-specific intrusions.
