What is an example of a physical security control?

Surveillance cameras serve as a prime example of a physical security control because they are designed to monitor and protect physical spaces. Unlike other controls that focus on logical or administrative measures, surveillance cameras are tangible devices placed in specific locations to deter, detect, or document unauthorized access or suspicious activities. They form a crucial part of physical security by providing real-time monitoring and recording events that can be reviewed later if an incident occurs.

This type of control is vital in safeguarding the physical assets of an organization as it can enhance situational awareness and serve as a deterrent against potential intruders. The recordings from surveillance cameras can also be used as evidence in legal cases or in investigations following security incidents, further showcasing their importance in a comprehensive security strategy.

In contrast, other options like encryption software, firewall configurations, and access control lists are primarily related to protecting information systems and data rather than the physical environment itself, which clearly differentiates surveillance cameras as a physical security measure.
