A Novel Header Matching Algorithm For Intrusion Detection Systems

Abstract

The evolving necessity of the Internet increases the demand on the bandwidth. Therefore, this demand opens the doors for the hackers' community to develop new methods and techniques to gain control over networking systems. Hence, the intrusion detection systems (IDS) are insufficient to prevent/detect unauthorized access the network. Network Intrusion Detection System (NIDS) is one example that still suffers from performance degradation due the increase of the link speed in today's networks. In This paper we proposed a novel algorithm to detect the intruders, who's trying to gain access to the network using the packets header parameters such as; source/destination address, source/destination port, and protocol without the need to inspect each packet content looking for signatures/patterns. However, the "Packet Header Matching" algorithm enhances the overall speed of the matching process between the incoming packet headers against the rule set. We ran the proposed algorithm to proof the proposed concept in coping with the traffic arrival speeds and the various bandwidth demands. The achieved results were of significant enhancement of the overall performance in terms of detection speed.

Effectiveness and Weakness of Quantified/Automated Anomaly Based IDs

“…Swatch and Logsurfer use also sys-log to detect malicious packets. In these other ones, pattern matchings applied [2], [3], [5], effective signature generation methods [9] and other techniques are developed. These types of IDS can judge recent sessions which are almost known attack methods and are already analyzed.…”

Intrusion Detection System Using Discrete Fourier Transform with Window Function

“…In signature-based IDS,characteristic of intrusion packets are stored as signaturesin a database [1][2] [4][10] [14]. By comparing contents of captured packetswith the signatures, intrusion packets can be detected.…”
