ABSTRACT:
System and methodology for intrusion detection and prevention is described. In one embodiment, for example, a method is described for detecting and preventing network intrusion, the method comprises steps of: defining intrusion descriptions specifying exploits that may be attempted by malicious network traffic, the intrusion descriptions indicating specific applications that may be targeted by individual exploits; for a particular application participating in network communication, deriving a subset of the intrusion descriptions specifically applicable to that particular application; using the subset of the intrusion descriptions specifically applicable to that application, monitoring network traffic destined for the particular application for detecting an attempted network intrusion; and if a network intrusion is detected, blocking network traffic destined for the particular application determined to comprise an exploit.
