ABSTRACT
Network security has been an issue almost since computers have been networked toge ther. Since the evolution of the internet, there has been an increasing need for security systems. One important type of security software that has emerged since the evolution of the internet is intrusion detection systems. An intrusion occurs when an attacker gains unauthorized access to a valid userâ„¢s account and performs disruptive behavior while masquerading as that user. The attacker may harm the userâ„¢s account directly and can use it to launch attacks on other accounts or machines. Developing signatures of users of a computer system is a useful method for detecting when this scenario happens. Our approach concentrates on developing precise user signatures characterizing multiple aspects of user activity. Thus, anytime someone behaves in a manner inconsistent with their signature, our system will raise an alarm which strength corresponds to the unlikelihood of the current behavior to the signature.
