Which of the following is a physical security measure that can protect data?

The correct answer is secure rooms, safes, and locked cupboards, as these are tangible, physical security measures designed specifically to protect data and sensitive information. By storing data in secure environments, organizations can restrict access to authorized personnel only, thereby reducing the risk of unauthorized access, theft, or damage.

Physical security is crucial because it acts as the first line of defense against various threats, including theft, vandalism, and natural disasters. By utilizing secure rooms that are reinforced and monitored, and storing physical media such as hard drives or documents in safes and locked cupboards, organizations can ensure that critical data remains confidential and protected.

In contrast, options like open plan offices typically lack the necessary privacy and security for sensitive information, leading to potential exposure. Cloud storage solutions, while beneficial for data accessibility and collaboration, do not constitute a physical security measure. They rely on digital security protocols rather than preventing physical access to data. Public sharing platforms also do not offer a secure environment for data, as they are designed for visibility and sharing rather than protection.
