The primary purpose of physical access controls is to prevent unauthorized access to computer software.

• A. True
• B. False
• C. Only for data centers
• D. Depends on the system

Answer: (B)

Physical access controls aim to keep the actual hardware, devices, and the environments they reside in secure from unauthorized entry, tampering, theft, or disruption. They protect the physical layer of security—things like doors, locks, surveillance, and restricted areas—so that the equipment and data it holds aren’t easily compromised. Controlling who can interact with software is done through logical or technical access controls, such as authentication, authorization, and encryption. Physical security helps prevent scenarios where someone could physically steal a device, tamper with it, or bypass software protections by manipulating the hardware, but the primary goal isn’t to restrict access to software itself. The statement is false because software access is governed mainly by logical controls, while physical access controls focus on protecting the hardware and the environment behind the scenes. It’s not limited to data centers, nor does it depend on the system—physical security is needed wherever there are devices that must be shielded from unauthorized physical access.
