Instant Messengers
SmartDefense can block instant messaging applications that use VoIP protocols, by
identifying the messaging application's fingerprints and HTTP headers.
This category includes the following nodes:
• Skype
• Yahoo
• ICQ
Note: SmartDefense can detect instant messaging traffic regardless of the TCP port
being used to initiate the session.
In each node, you can configure how instant messaging connections of the selected
type should be handled, using the table below.
