Intrusion Detection and Prevention System

详细技术说明

Executive Summary Deep packet inspection (DPI) filters computer network packets and examines the data in a packet, performing searches for viruses, spam, or other intrusions. DPI can be implemented on routers, network intrusion detection systems, firewalls and switches but detecting multiple patterns in parallel requires a significant amount of memory and tends to be a slow process. We present a more efficient method for conducting regular expression matching in networks for improved network security. Description of Technology This technology is a novel method for deep packet inspection of networks for intrusion detection, traffic monitoring and protocol identification. The algorithm accomplishes regular expression matching using ternary content addressable memories (TCAMs). By grouping similar sets of regular expressions into one state, less memory is required and regular expression matching can be conducted faster than previous methods.  Key BenefitsHigh Throughput: this algorithm performed regular expression faster than all other algorithms it was tested against Less Memory Required: uses order of magnitude less TCAM than previous technology Uses existing versions of TCAM chip ApplicationsRoutersFirewallsIntrusion Detection/Prevention Devices Patent Status:  Patent Pending, US Patent Publication US2015-0310342 Licensing Rights Available Full licensing rights available Inventors: Alex Liu, Eric Torng Tech ID: TEC2014-0106
