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

A physical control refers to tangible measures taken to protect an organization’s physical assets and safeguard against unauthorized access, theft, and other risks to the physical security of information systems. Surveillance cameras and locks are quintessential examples of physical controls because they directly involve physical barriers and monitoring capabilities that manage access to a facility or specific areas within it.

By employing these physical controls, organizations can deter unauthorized attempts to access sensitive areas and maintain the safety of both their assets and personnel. Surveillance cameras act as a deterrent and also assist in monitoring activities, while locks secure physical entries to prevent unauthorized entry.

In contrast, encryption techniques, user access logs, and disaster recovery plans are all examples of logical or administrative controls that relate to managing access to information systems and data rather than physical spaces. These controls, while important for overall security, focus more on the procedural and software aspects of security rather than the physical measures required to protect hardware or facilities.
