Which term is defined as a piece of equipment used to prevent undesired openings, typically an aperture?

• A. Policy
• B. Mitigation
• C. Lock
• D. Management

Answer: (C)

The main idea here is a physical security device that stops openings of an entry point. A lock fits that description exactly: it’s a device attached to doors, windows, or other openings that keeps them closed and inaccessible without the proper authorization, such as a key, combination, or access credential. This makes it a concrete way to enforce access control and protect the space from undesired entry. In contrast, policy refers to rules governing behavior, mitigation is about reducing risk through actions, and management involves coordinating people and resources. These are abstract or organizational concepts, not a physical device used to secure an aperture.
