What is defined as physical security?

Physical security refers to measures designed to safeguard tangible assets—such as buildings, equipment, and resources—from threats that could cause physical harm or loss. This encompasses a variety of strategies, including access control, surveillance, environmental design, and deterrence methods to mitigate risks like theft, vandalism, or natural disasters.

In the context of security, it's critical to distinguish between physical security and cybersecurity, as the former deals specifically with preventing unauthorized access to physical locations and protecting real-world assets. Typical measures include installing security cameras, employing security personnel, using locks and barriers, and implementing visitor management systems.

The other options focus on aspects that are not directly linked to physical security: safeguarding financial assets from online threats aligns more with cybersecurity strategies, virtual security teams relate to digital security frameworks, and protocols for communicating with authorities pertain to procedures for emergency response and collaboration rather than the physical safeguarding of assets. Therefore, the correct choice encompasses the core intent of physical security, which is to protect physical assets from various kinds of threats.
