CompTIA SecurityX (CAS-005)Security EngineeringEasy
A security architect is designing a key management system for a global enterprise that processes vast amounts of encrypted data. The solution must ensure that encryption keys are generated, stored, and managed in a highly secure, tamper-resistant environment, meeting stringent compliance requirements for cryptographic module validation. Which specialized hardware device is MOST suitable for this purpose?
- AHardware Security Module (HSM)
- BSmart Card
- CField-Programmable Gate Array (FPGA)
- DTrusted Platform Module (TPM)
Show answer & explanationAnswer & explanation
Correct answer: A. Hardware Security Module (HSM)
A Hardware Security Module (HSM) is a physical computing device that safeguards and manages digital keys for strong authentication and provides cryptoprocessing. It is specifically designed to meet rigorous security standards like FIPS 140-2, ensuring tamper resistance and secure key lifecycle management, which is ideal for the described scenario.
Why the other options are wrong
- B. A smart card is a small, portable device primarily for individual user authentication and key storage, not for centralized enterprise key management.
- C. An FPGA is a reconfigurable integrated circuit used for custom hardware acceleration, not specifically for secure key management or cryptographic module validation.
- D. A TPM provides hardware-based security functions for a single host, primarily for platform integrity and secure boot, but not for enterprise-wide key management in a tamper-resistant environment for large-scale data.
Hardware Security Module (HSM)
A Hardware Security Module (HSM) is a physical computing device that safeguards and manages digital keys, performs cryptographic operations, and provides strong authentication within a tamper-resistant environment.
- Provides FIPS 140-2 validated cryptographic processing.
- Protects keys from logical and physical attacks.
- Used for certificate authorities, database encryption, code signing.
Memory trick: Keys are safe in the HSM vault, away from prying eyes.
