Which option is NOT a hardware protection method listed?

• A. Install hidden security software
• B. Mark components with ultraviolet pen
• C. Use motion sensors
• D. Use lockable cabinets to store system units

Answer: (A)

The main idea is telling apart hardware protection from software protection. Hardware protection uses physical measures to protect the devices themselves, their components, and access to them. The option that isn’t a hardware protection method is the one about installing hidden security software, because that relies on software running on the system to protect it, not on physical safeguards. The other options are physical safeguards: marking components with ultraviolet ink helps identify tampering or theft on the hardware itself; motion sensors monitor the area around the hardware to detect unauthorized movement; and lockable cabinets physically restrict access to the system units. So, the software-based option is the one that does not fit as a hardware protection method.
