What are physical access controls primarily designed to do?

Physical access controls are primarily designed to prevent unauthorized access to physical locations. These controls include various measures and mechanisms, such as locks, security guards, biometric scanners, and surveillance cameras, which secure buildings, rooms, and other physical spaces where sensitive information or critical infrastructure is housed.

By implementing effective physical access controls, organizations can protect their assets, personnel, and confidential data from theft, damage, or compromise. This is crucial because even the most secure digital systems can be undermined by someone gaining physical access to hardware and facilities, allowing them to manipulate or steal information directly.

The other options focus on aspects that relate more to cyber security or data protection rather than physical security. For instance, monitoring user behavior online pertains to software and user activity, while encryption relates to securing data rather than controlling physical space. Thus, the importance of physical access controls lies in their ability to safeguard tangible locations against unauthorized access, ensuring a secure environment for operations.
