Which term describes a collection of hardware, software, and firmware that implements cryptographic processes within a defined boundary?

• A. Secure Wipe
• B. Secure Cryptographic Device
• C. Schema
• D. Security Event

Answer: (B)

A secure cryptographic device describes a self-contained set of hardware, software, and firmware that performs cryptographic operations within a defined boundary. This boundary keeps all key material and cryptographic processes inside a controlled environment, providing protection against tampering and leakage and enabling proper access control and auditing. That makes it the best fit for a collection of components that implements cryptographic functions inside a defined boundary.

For context, devices like Hardware Security Modules (HSMs) or trusted platform components are typical examples, designed to keep keys secure and operations isolated from the rest of the system. The other options don’t describe a cryptographic processing environment: secure wipe is about erasing data securely, a schema is about data structure, and a security event is a logged incident or alert.
