Which of the following is an example of a physical safeguard in a data security program?

Locking computer rooms is a solid example of a physical safeguard in a data security program. Physical safeguards are measures that protect the physical infrastructure of an organization where sensitive data is stored, accessed, or used. By locking computer rooms, the organization restricts unauthorized access to hardware and sensitive information, mitigating risks associated with theft, tampering, or data breaches. This form of security ensures that only authorized personnel can access critical systems and sensitive information, contributing to the overall data security strategy.

In contrast, using password protection relates more to technical safeguards, as it involves securing access to systems through user authentication. Prohibiting the sharing of passwords is a procedural safeguard focused on promoting proper security behavior among staff, while annual employee training is also a procedural measure aimed at educating employees about data security and best practices. All these options are important components of a comprehensive data security program but fall under different categories of safeguards.
