ANSI / ASIS PAP.1-2012 Physical Asset Protection APP Practice Exam

In a physical protection system, the function that addresses slowing down an attacker is the delay function. It uses barriers, barriers, controlled access, and other measures to increase the time and effort an adversary must expend to reach the target. This added time gives detection systems a chance to sense the intrusion and responders the opportunity to intervene before access is achieved. Deterrence aims to discourage attempts in the first place, detection focuses on sensing events, and response involves actions taken after an event is detected to stop or deny access. So delaying the adversary directly matches the purpose of the delay function.
