Kuppusamy Journal on Software Engineering 2230 – 7168 10 1 31 41 Intelligence Intrusion Detection Prevention System (IIDPS), Unknown Malware, Intelligence Intrusion Multi Detection Prevention Systems (IIMDPS) Research on intelligence Intrusion Detection Prevention Systems (IDPSs) found in the literature survey are effectively used to identify and detect only known Network attacks and are unable to evaluate the risk of Network service. In order to overcome limitations of the existing Intrusion Detection System (IDS), a new active defense system with Intelligence principles named IIDPS (Intelligence Intrusion Detecton Prevention System) for detecting and preventing unknown malware has been proposed in this article. This system fulfills the objectives of security like authenticity, confidentiality, integrity, availability, and non-repudiation. July - September 2015 Copyright © 2015 i-manager publications.
