Abstract:
1. A system for rapid intrusion detection for a network communication comprising: a network processor; circuitry in the network processor for receiving network data from a network fabric; circuitry in the network processor for forwarding routed network data to the network fabric; circuitry for analyzing the packets of network data for validity thereby generating valid packets of network data as selected data; circuitry for coupling the network processor to a parallel pattern detection engine (PPDE) for comparing in parallel the selected data from the network data to M sequences of pattern data stored in the PPDE and generating a match output signal when at least one of the M sequences of pattern data compares to a portion of the selected data; circuitry for receiving packets of network data from the network fabric in the network process; circuitry for forwarding network data from the valid packets of network data to the PPDE, circuitry for comparing the selected data to N intrusion signatures and generating, at network data speed, a pattern compare signal and a particular ID data when a particular one of the N intrusion signatures is detected; and circuitry for executing an action code corresponding to the particular one of the N intrusion signatures detected; wherein the PPDE comprises:
