Which of the following is an example of a physical security control?

A physical security control refers to measures designed to protect physical assets and spaces from unauthorized access, damage, or theft. Security cameras serve as a clear example of a physical security control because they monitor and record activities in a specific area, deterring potential intruders and providing evidence in the event of a security incident. The presence of security cameras can help ensure the safety of personnel and physical assets, forming an essential component of a broader security strategy.

While firewalls, antivirus software, and encryption methods are vital for protecting information and securing networks, they do not fall under the category of physical security controls. Instead, they are classified as technical or logical controls, which focus on safeguarding data and systems against cyber threats rather than physical threats to tangible assets. Understanding the difference between these types of security measures is fundamental when designing a comprehensive security plan.
