Which of the following would be BEST to use to store customer keys?

Answer options

• A. A trusted platform module
• B. A hardware security module

Correct answer: B

Explanation

The correct answer is B, a hardware security module, as it provides a secure and compliant environment for key management, ensuring the protection of sensitive data.
