This work introduces flexibility to IDS by inculcating a mechanism that enables the IDS to accommodate changes in the pattern of user’ behavior. The mechanism allows a user to authenticate his or her identity whenever the IDS observes a change in the mode of operation of IDS system. The proposed intrusion system is described as, Inspection-Based Anomaly system. The performance of the Inspection-based system was evaluated on a benched marked data. Using accuracy measure, F1, it was observed that the Inspection-based anomaly system outperforms the conventional anomaly-based system with 2.6% and outperform the best-known intrusion detection system with an accuracy of 2.8% on the same dataset. The Inspection based system is able to achieve a false positive rate that is as low as 4.9%. Therefore, the Inspection based anomaly system is recommended for use in a dynamic environment where the user’s activity is subject to changes that might occur due to unforeseen circumstance.enAttribution 4.0 InternationalDesignSystemDesign of An Adaptive Intrusion Detection System Using Inspection-Based Anomaly ModelDissertation
