Abstract

A system and method provide a security agent, consisting of a monitor and a responder, that respond to a detected security event in a data communications network, by producing and transmitting a security alert message to a network security manager. The alert is a security administration action which includes setting a flag in an existing transmitted protocol frame to indicate a security event has occurred. The security agent detects the transmission of infected programs and data across a high-speed communications network. The security agent includes an adaptive, active monitor using finite state machines, that can be dynamically reprogrammed in the event it becomes necessary to dynamically reconfigure it to provide real time detection of the presence of a suspected offending virus.
