Which term describes a department within a company that provides security services?

• A. Protection in Depth
• B. Records
• C. Preparedness
• D. Proprietary Security

Answer: (D)

Internal, in-house security functions are described as proprietary security. This term signals ownership by the company and integration with its operations, meaning the security services are provided by an internal department rather than an external contractor. It covers staffing, policies, training, and day-to-day protection of assets across the organization. The other terms describe approaches or functions rather than a department: Protection in depth refers to a layered defense strategy, Records to documentation management, and Preparedness to readiness and planning for incidents.
