TL;DR: In this article, the authors argue that mobile agent technology goes a long way toward realizing the ideal behavior desired in an intrusion detection system (IDS), and discuss various ways in which mobile agents could be applied to the problem of detecting and responding to intrusions.
Abstract: Implementing an effective intrusion detection capability is an elusive goal, not solved easily or with a single mechanism. However, we argue that mobile agent technology goes a long way toward realizing the ideal behavior desired in an intrusion detection system (IDS). This paper discusses various ways in which mobile agents could be applied to the problem of detecting and responding to intrusions. The paper looks not only at the benefits derived from mobility, but also at those associated with software agents in general. After exploring these benefits, we outline a number of ways to apply mobile agent technology in addressing the shortcomings of current IDS designs and implementations, and delineate the associated security issues involved. We also look at several new approaches for automated responses to an intrusion, once detected.

TL;DR: In this paper, a laser perimeter intrusion detection system is proposed, which includes means for providing laser beam components for defining the perimeter of a predetermined geographical area to be protected. But the system is not suitable for the use of the human eye.
Abstract: A laser perimeter intrusion detection system which includes means for providing laser beam components for defining the perimeter of a predetermined geographical area to be protected. The system includes a sensing subsystem which is comprised of a plurality of sensors for providing electrical outputs from the sensors, the electrical outputs being responsive to interruption of any of the laser beam components. The system has an electrical signal-processing and logic subsystem for identifying the specific portion of the perimeter controlled by any of the laser beam components when the particular component is traversed by an intruder. Included are means for chopper-modulating the laser beam to increase the difficulty of compromising the system and to make the laser beam invisible to the human eye.

TL;DR: In this paper, a surveillance and intrusion detection system is presented which embodies within a single electro-optical device located at one of many sites, surveillance motion detection and pictorial information with enhancement of the outline of a moving object once its presence is detected and an alarm signal is transmitted to a control station.
Abstract: A surveillance and intrusion detection system is provided which embodies within a single electro-optical device located at one of many sites, surveillance motion detection and pictorial information with enhancement of the outline of a moving object once its presence is detected and an alarm signal is transmitted to a control station. Two lockout circuits receive alarm signals from the first two sites to detect a moving object and route composite video signals to display monitors. One full frame is stored for display by the monitor until an operator actuates an override switch for continuous monitoring of the site having the alarm condition, or any other site the operator may select for monitoring. Magnetic tape units are connected to the display monitors for storing pictorially the events at a site being monitored.

TL;DR: In this paper, an intrusion detection system with a motion alarm which responds to a Doppler frequency signal is presented, and a supervisory alarm is also provided which can respond to a frequency higher than any frequency within such band.
Abstract: This disclosure includes an intrusion detection system with a motion alarm which responds to a Doppler frequency signal. The motion-related Doppler frequency signals cover a predetermined frequency band and the alarm circuit is constructed to respond to all signals above a selected minimum amplitude within such band. A supervisory alarm is also provided which responds to a frequency higher than any frequency within such band. A jamming alarm circuit is provided which responds to a signal above a selected amplitude greater than the motion alarm selected amplitude and essentially independent of frequency.
