What does a physical countermeasure primarily involve?

A physical countermeasure primarily involves designing and implementing strategies for security infrastructure. This focuses on the tangible aspects of security, which could include things such as securing the perimeter of a facility with fences or barriers, installing surveillance cameras, using access control systems, and ensuring physical security personnel are in place. The objective of these measures is to prevent unauthorized access to physical locations and protect sensitive information and assets.

In contrast, psychological training of staff, while important for security awareness, does not directly address physical safeguards. Technological upgrades that focus only on software may enhance cybersecurity but do not constitute physical countermeasures. Additionally, cost-reduction measures are generally focused on budget considerations rather than the implementation of physical security strategies. Thus, the emphasis on infrastructure design and safety protocols is crucial for a comprehensive security approach.
