CompTIA CySA+ (CS0-002) — Question 158

Which of the following BEST describes HSM?

Answer options

• A. A computing device that manages cryptography, decrypts traffic, and maintains library calls
• B. A computing device that manages digital keys, performs encryption/decryption functions, and maintains other cryptographic functions
• C. A computing device that manages physical keys, encrypts devices, and creates strong cryptographic functions
• D. A computing device that manages algorithms, performs entropy functions, and maintains digital signatures

Correct answer: B

Explanation

Option B is correct because an HSM (Hardware Security Module) specifically focuses on managing digital keys and performing cryptographic operations. The other options either mischaracterize the role of an HSM or focus on aspects that are not primarily its function, such as managing physical keys or algorithms.
