Abstract:

An application specific distributed firewall provides a series of wrappers around network applications communicably linked to a registry server. Each wrapper is associated, within the registry server, with at least one group of wrappers, so that the wrapper of a compromised application may inform the registry server of an unauthorized access, which may then inform all group members. The wrappers of the noncompromised group applications may then restrict communication with the compromised application.
