What are the two types of physical barriers?

• A. Natural and Structural
• B. Electrical and Mechanical
• C. Visual and Audible
• D. Thermal and Magnetic

Answer: (A)

Two types of physical barriers are natural barriers and structural barriers. Natural barriers are features of the landscape that impede movement, like rivers, mountains, canyons, deserts, or dense vegetation. Structural barriers are man-made protections designed to block or deter access, such as fences, walls, gates, barricades, or trenches. Understanding this distinction helps in security planning because you assess how the terrain itself slows or channels movement (natural) and then consider engineered protections added to reinforce or extend that protection (structural). The other options describe qualities or senses rather than broad categories of barriers, so they don’t fit as the primary ways we classify physical barriers.
