Patent attributes
A user agent residing within a remote client and configured to enforce message protocol policy is disclosed. The user agent includes a communications monitoring element that examines a communications connection between the client and an external message server to determine if the message server matches a restricted server attribute. The user agent also includes a communications controller element that works with the communications monitoring element to block communications between the client and the message server when the message server matches a restricted server attribute unless the communications are monitored by a protocol inspection gateway. The gateway intercepts the communications between the client and the message server and inspects a message protocol associated with the intercepted communications to determine if the message protocol matches a protocol definition file, and when a match occurs, apply a policy enforcement rule that overrides aspects of the message protocol associated with the intercepted communications.
