Physical Security Professional Certification Practice Exam

Which three measures do physical protection systems operate under?

1. Physical protection, logical protection, and protection-in-depth

2. Cyber security, physical security, and risk management

3. Corrective, Detective, and Preventative

4. Threat, Vulnerability, and Risk

The correct answer is: Corrective, Detective, and Preventative

Physical protection systems fundamentally rely on three essential measures: corrective, detective, and preventative. Preventative measures are designed to stop incidents before they occur, focusing on deterrence and reducing vulnerabilities in the security infrastructure. For instance, implementing access control systems or surveillance cameras can deter potential intruders and minimize the risk of unauthorized access. Detective measures come into play once an incident has occurred or is in the process of occurring. These measures identify and alert security personnel to potential threats, allowing for a swift response. Tools such as alarms and motion detectors fall into this category, as they help to detect breaches in real-time. Corrective measures are the actions taken after a security incident has been identified. They aim to restore normal operations and address any damage caused or vulnerabilities exploited during an incident. This could involve repairing physical damage, revising security protocols, or conducting investigations to prevent recurrence. Together, these three measures create a comprehensive framework for a physical protection system, ensuring that security is not only reactive but also anticipatory and restorative. Understanding this triad is crucial for developing effective security strategies in any physical protection scenario.
