SSL: Non-SSL Traffic on SSL Port
This signature detects TCP sessions that are not SSL, but are using the default SSL port of 443. This can be an indicator that a non-SSL program (such as Peer-to-Peer file sharing, proxy servers, or Voice over IP) is attempting to circumvent security and tunnel through the firewall.
