Survey of Bio-Inspired Techniques based on System Resource Usage in Intrusion Detection

Abstract

The presented work is a study of literatures inspired by nature and natural organisms in detecting intrusions. The study takes into consideration the usage of system resources of a computer or a network. The paper focuses on the notion that intrusion and intrusive activities are less frequent in comparison to the normal activities of a system. And in order to capture such intrusive activities, there must be a provision for incorporating an intrusion detection system that can constantly examine the day-to-day activities of the system. Therefore, an intrusion detection system would check the system activities by keeping a log or account of the system behavior. To ascertain whether the activity is normal or not, one has to monitor the system behavior based on the system resources being utilized. Resource usages can be captured to check the currently running programs, their network bandwidth usages, memory usage, processor usages etc. Similarly, user-based behaviors can be obtained from their login frequency or the number of password attempts to a known system. All these behaviors can be taken into consideration for further validating the assumption that whether an intrusion has actually occurred or not. This paper presents some literatures inspired by nature and natural organisms. It emphasizes on the literatures based on some biological principles.
