What is a primary goal of the 'Obstacles and prevention' category in physical security?

The primary goal of the 'Obstacles and prevention' category in physical security is to deter unauthorized access. This approach focuses on implementing physical barriers and controls designed to make it challenging for intruders to gain entry to a facility or a restricted area. Strategies such as locks, fences, access control systems, and security personnel serve to discourage potential threats by increasing the difficulty and risk associated with unauthorized access.

By effectively deterring unauthorized individuals, organizations can minimize the risk of theft, vandalism, or other malicious activities, thereby enhancing the overall security posture. This prevention strategy is foundational in physical security, as it not only protects valuable assets but also ensures a safer environment for personnel. While monitoring activities, recovering lost assets, and documenting incidents are critical components of an overall security strategy, they primarily serve to respond to events after they occur rather than to prevent unauthorized access in the first place.
