ABSTRACT:
Techniques are provided for performing security functions on a message payload in a network element. According to one aspect, a network element receives one or more data packets. The network element performs a security function on at least a portion of an application layer message that is contained in one or more payload portions of the one or more data packets. According to another aspect, a network element receives a first request that is destined for a first application. The network element sends, to a second application that sent the first request, a second request for authentication information. The network element receives the authentication information and determines whether the authentication information is valid. If the authentication information is not valid, then the network element prevents the first request from being sent to the first application.
