  HTTP Proxy -- App Message (Keep Alive)

Category: PROXY-ACCESS      

Application: HTTP Proxy      

A host on the internal network is attempting to use an http proxy on the external network. While this event most likely is not part of an attack, this activity may lead to application usage against company policy, like MSN Messenger or other IM and P2P applications.

This SonicWALL signature can detect and prevent http proxy server usage.
