Physical Security Professional Certification Practice Exam 2025 – Comprehensive Prep Guide

The three main prevention functions of the Security Triangle are best represented by the terms Deter, Detect, and Delay. This concept is foundational in understanding how physical security measures work together to protect assets and mitigate risks.

Deter refers to actions taken to discourage potential threats from attempting to breach security measures. This can include visible security measures, like personnel or surveillance systems, which can make an attack seem less appealing.

Detect involves identifying potential threats or breaches as they occur. Effective detection systems prompt immediate responses, enabling security personnel to take action before any significant harm or loss occurs.

Delay relates to implementing physical barriers or logistical measures that slow down intruders, providing additional time for detection or response. This could include features like reinforced doors or security checkpoints that an intruder must pass through, effectively slowing their progress.

While prevention is a key aspect of security, the specific framework of the Security Triangle emphasizes the interplay of these three functions to create a robust security posture. Therefore, the correct answer highlights how these elements work synergistically to safeguard an environment.
