Which term refers to a software or hardware component used to restrict access?

• A. Steganography
• B. Technical Control
• C. System-specific Policies
• D. Standard

Answer: (B)

Technical controls are security measures implemented through software or hardware to restrict access to resources. They enforce who can access data or systems and what they can do, using mechanisms such as authentication, authorization, access control lists, encryption, and firewalls. In this question, the term describes exactly what a software or hardware component that limits access does—it's a technical control. Steganography hides data within other data, which is unrelated to access restrictions. System-specific policies are administrative rules rather than a concrete technology component, and a standard is a guideline or requirement, not a direct access-control mechanism.
