Abstract: Intrusion Detection and Prevention Systems generally aims at detecting -preventing attacks against Information systems and networks. The basic task ofIDPS is to monitor network and system traffic for any malicious packets-patternsand hence to prevent any unwarranted incidents which leads the systems toinsecure state. The monitoring is done by checking each packet for its validityagainst the signatures formulated for identified vulnerabilities. Since,signatures are the heart and soul of an Intrusion Detection and Prevention SystemIDPS, we, in this paper, discuss two methodologies we adapted in our researcheffort to improve the current Intrusion Detection and Prevention IDP systems.The first methodology RUDRAA is for formulating, verifying and validating thepotential signatures to be used with IDPS. The second methodology DSP-FED isaimed at processing the signatures in less time with our proposed fastelimination method using DFA. The research objectives of this project are 1 Toformulate and process potential IPS signatures to be used with Intrusionprevention system. 2 To propose a DFA based approach for signature processingwhich, upon a pattern match, could process the signatures faster else couldeliminate it efficiently if not matched
