What is an example of a physical security control?

A physical security control is designed to protect physical assets, personnel, and facilities from unauthorized access or damage. Security cameras serve as a key example of this type of control because they are directly involved in monitoring and recording activities within a physical space, thereby deterring potential intruders and providing evidence in the event of an incident.

In a security context, security cameras help to ensure the safety of premises by enabling real-time surveillance and the ability to review recorded footage later for investigations. This measure adds a layer of protection by enhancing awareness of the environment and assisting in maintaining security protocols.

In contrast, other options like firewalls and antivirus software are examples of logical security controls, which focus on protecting data and systems from cyber threats, while encryption is a method of securing data by transforming it into a format that cannot be read without the proper keys. None of these options provide the physical surveillance and monitoring capabilities that security cameras do, thus reinforcing their classification as physical security controls.
