Security system analytical performance analysis is generally based on the probability of system effectiveness. The probability of effectiveness is a function of the probabilities of interruption and neutralization. Interruption occurs if the response forces are notified in sufficient time to engage the adversary. Neutralization occurs if the adversary attack is defeated after the security forces have actively engaged the adversary. Both depend upon communications of data. This paper explores details of embedded communications functions that are often assumed to be inconsequential. It is the intent of the authors to bring focus to an issue in security system modeling that, if not well understood, has the potential to be a deciding factor in the overall system failure or effectiveness.

The purpose of this report is to provide school administrators with the ability to determine their security system requirements, so they can make informed decisions when working with vendors and others to improve their security posture. This is accomplished by (1) explaining a systems-based approach to defining the objectives and needs of the system, and (2), providing information on the ability of common components (sensors, cameras, metal detectors, etc) to achieve those objectives, in an effectively integrated system.
