In the modern world of security many researchers have proposed various new approaches; among those techniques application of data mining for Intrusion detection is one of the best suitable approaches.The system proposes a security system, name the Intrusion Detection and Protection System (IDPS) at system call level, which creates the personal profile for the user to keep track of user usage habits as the forensic features. The IDP uses a local computational grid to detect malicious behavior in a real-time manner. In this paper, a security system, named the IDPS is proposed to detect insider attacker at SC level by using data mining and forensic techniques.
