What is a primary function of physical controls?

A primary function of physical controls is to secure the physical environment. This involves implementing measures that protect facilities, equipment, and physical assets from unauthorized access, damage, or interference. Examples of physical controls include locks, access control systems, security guards, and surveillance cameras. These controls are vital for creating a secure infrastructure that restricts access to sensitive areas and ensures that only authorized personnel can enter secure locations.

Physical controls serve as the first line of defense in an organization's overall security strategy. They help mitigate risks associated with physical threats, such as theft, vandalism, and natural disasters, by establishing barriers and monitoring access to critical areas. By securing the physical environment, organizations can protect not only their physical assets but also the data and information that those assets may contain.
