Biometric Authentication for Intrusion Detection Systems

Most of the currently available intrusion detection systems do not provide any authentication functionality in order to identify the users who access a computer system. In particular, insiders are able to misuse their privileges without being detected. Some intrusion detection systems aim to authenticate legitimate users once they log in to the system, as well as to prevent access to unauthorized people who try to impersonate other users. The main goal of this paper is to introduce and implement a novel approach that uses the fingerprint technique to complement a host-based intrusion detection system in order to improve its level of authentication, which would allow us to detect more effectively any misuse of the computer system that is running it.
