Which component of security is focused on preventing unauthorized access to equipment and safeguarding personnel?

• A. Physical Security
• B. Information Security
• C. Personnel Security
• D. Cybersecurity

Answer: (A)

Protecting people and tangible assets through physical measures is the focus here. Physical security covers the barriers, controls, and procedures that prevent unauthorized people from reaching equipment and ensure that anyone on site is safe. Think of access controls like doors, locks, badge readers, guards, and surveillance, plus secure facilities and safe work practices to keep both devices and personnel out of harm's way.

This is the best choice because it directly targets stopping unauthorized entry to equipment and protecting the people who work around it. Information security, by contrast, is about protecting data and information systems from theft or tampering in digital form. Cybersecurity concentrates on defending networks, software, and online threats. Personnel security deals with ensuring the people involved are trustworthy and properly vetted. The physical controls and on-site safety measures described are what specifically address access to equipment and the safety of staff on the premises. A secured data center with controlled entry and on-site security illustrates this focus in action.
