WEMA to Speed up NIDS Packet Header Detection Engine

The traditional firewall provides the first level of defense for computer networks and prevents unauthorized people to access the internal networks from the external attacks. Thus, the Network Intrusion detection System (NIDS) is complementary to the firewall. One of the major functions of NIDS is to act as misuse detection. In This paper we used A Neural network with multi-connect architecture and Weighted Exact Matching Algorithm (WEMA) to enhance the speed of matching process between the incoming packets header and SNORT-NIDS rule sets.
