Abstract
A system validates the establishment and/or continuation of a connection between two applications over a network using a two-stage process: (1) a local security agent executing on the same source system as the source application validates the connection against a set of policies stored locally on the source system; and (2) a local security agent executing on the same destination system as the destination application validates the connection against a set of policies stored locally on the destination system. The connection is allowed or blocked depending on the outcome of the two-stage validation. Before the validation process, a policy enforcement engine distributes copies of a trusted public certificate to the source and destination local security agents, which extend their local copies of the certificate to enable them to enforce policies without the use of a backend system.
