CompTIA A+ 220-1101 Practice Question

An HSM is a physical computing device that safeguards and manages digital keys, and it performs encryption and decryption functions for secure environments. It provides secure storage and generation of cryptographic keys and is designed to be tamper-resistant, thus offering a robust security option for handling cryptographic operations and sensitive data. While TPM and UEFI provide hardware-based security features, they do not offer the same level of protection and functionality for cryptographic key management as an HSM does. A firewall is essential for network security, but it does not specialize in cryptographic processing or key management.
