  • Inline intrusion detection
    Patent number: 9009830
    Abstract: A method for inline intrusion detection includes receiving a packet at a network gateway, storing the packet, and assigning an identifier to the packet. The method also includes transmitting a copy of the packet and the identifier from the network gateway to an intrusion detection system and analyzing the copy of the packet by the intrusion detection system to determine whether the packet includes an attack signature and communicating a reply message from the intrusion detection system to the network gateway. The reply message includes the identifier and is indicative of the results of the analysis. The size of the reply message is less than the size of the packet.
    Type: Grant
