Abstract
The increasing speed of today’s computer networks directly affects the performance of Network Intrusion Detection Systems (NIDS) in terms of speed of detection of threads. Therefore, the performance of the existing algorithms needs to be improved to enhance the speed of detection engine used in NIDS applications. Hence, this paper defines a new platform NIDS to enhance the speed of detection engine based on Weighted Exact Matching Algorithm (WEMA). Furthermore, this platform can be run in sequential and in parallel mode, using the pthread techniques, in order to increase the total performance of NIDS applications.
