New Methods of Intrusion Detection using Control-Loop Measurement

This paper describes a new concept in network intrusion detection based up statistical recognition of an intruder's control-loop. These criteria offer advantages in infinite networks and where a priori attack scenarios are not known. This paper describes the need for better intrusion detection methods, the applicability of digital signal processing to real-time network surveillance, the concept of controlloop behavior, and the design of an innovative intrusion detection system employing these. We also discuss the benefits of this new system in comparison with alternative technologies.
