Analysis, design and implementation of intelligent intrusion detection systems

In this thesis, intrusion detection systems (IDSs) which are important tools for providing information and computer security were analyzed, the methods used in developing IDSs were reviewed, the studies on IDS?s were revised, and an intelligent IDS was developed and introduced in this thesis. A detailed analysis about the intelligent IDSs, was presented and these IDSs were compared to the classical IDSs. In the light of those, an intelligent IDS was developed in this study. In this study, an intelligent IDS based on artificial neural network (ANN) was introduced. The database used in developing and testing IDS applications was also reviewed. The intelligent IDSs using KDD?99 database were also focused on. The developed IDS was also tested and compared to the available IDSs. According to the reviews, the evaluations and the experiences gained on IDSs during this study, it can be concluded that this study might contribute to improve the studies on information and computer security being done in near future and bring more awareness and perceptions to the security issues.
