What prevents unauthorized entry into a facility?

Protective barriers are specifically designed to prevent unauthorized entry into a facility. These barriers can take many forms such as fences, walls, gates, locks, and security systems that physically restrict access to a facility or sensitive areas within it. The presence of these barriers acts as a first line of defense against intruders, making it difficult for unauthorized individuals to gain access.

While organizational policies and employee training are crucial components of a comprehensive security program, they contribute more to awareness and compliance rather than creating physical obstructions to unauthorized entry. Similarly, the office layout can influence the flow of people within a space but does not directly prevent unauthorized access in the way that protective barriers do. Thus, the emphasis on physical security measures showcases their primary role in safeguarding a facility from potential threats.
