Mastering Physical Security Concepts

Which of the following access control methods involves using a combination of hardware and software to restrict access to a physical location?

• Biometric authentication

• Multi-factor authentication

• Role-based access control

• Discretionary access control

Answer explanation

Multi-factor authentication combines hardware (like key fobs) and software (like apps) to enhance security by requiring multiple forms of verification, making it effective for restricting access to physical locations.

Evaluate the effectiveness of using security guards versus electronic surveillance systems in a high-security environment. Which is more strategic for preventing unauthorized access?

• Security guards, because they can physically intervene

• Electronic surveillance, because it provides constant monitoring

• A combination of both, to leverage human judgment and technology

• Neither, as both have significant limitations

Answer explanation

A combination of both security guards and electronic surveillance is strategic as it utilizes human judgment for intervention and technology for constant monitoring, enhancing overall security against unauthorized access.

Analyze the strategic benefits of implementing a layered security approach in physical security controls. Which of the following best describes this approach?

• Using a single, robust security measure

• Combining multiple security measures to address different threats

• Relying solely on technology-based solutions

• Focusing on physical barriers only

Answer explanation

A layered security approach combines multiple security measures to address different threats, enhancing overall protection. This strategy mitigates risks by ensuring that if one layer fails, others remain to defend against potential breaches.
