1. A method of screening packets received from a communication network comprising: receiving a packet associated with one of an e-mail message, a VPN connection, and a web page response, the packet having a source; performing an intrusion detection analysis on the packet using a set of intrusion detection rules; if the packet passes the intrusion detection analysis, performing a firewall analysis on the packet using a set of firewall rules; if the packet passes the firewall analysis, determining if the packet is associated with an e-mail message, a VPN connection or a web page response; if the packet is associated with an e-mail message, performing a virus analysis on the packet using a set of virus definitions; if the packet is associated with a VPN connection, performing an authentication analysis on the packet using a set of authentication criteria; and if the packet fails any of the intrusion detection analysis, the firewall analysis, the virus analysis, or the authentication analysis, automatically generating a new intrusion detection rule to delete any subsequent packets received from the same source as the packet.
