Abstract:
A reverse firewall for removing undesirable traffic from a computing network, such as a virtual private network (VPN), is disclosed. The reverse firewall uses firewall rules that may be determined and maintained within the enterprise network to control communication sent between computers in the computing network. The reverse firewall rules may be used to identify the communications between computers in the network that are undesirable and/or intrusive. For example, a computer in a network that is infected with a worm or that is surreptitiously hosting a denial-of-service attack may be identified by the reverse firewall and quarantined. The reverse firewall may be implemented in hardware and/or software.
