Which system is used to manage the physical security of hardware?

The Hardware Security Module (HSM) is dedicated to managing and safeguarding the physical security of hardware components. HSMs are designed to protect against tampering and unauthorized access, ensuring that cryptographic keys and sensitive data are stored securely. They provide secure key management, cryptographic operations, and compliance with regulatory standards. By isolating critical functions and preventing direct access to sensitive processes, HSMs play a vital role in the overall security infrastructure of a system.

In contrast, while Encryption Service Modules and Data Security Units may provide data protection features, they do not specifically focus on the physical security of hardware components. Access Control Systems, on the other hand, manage entry to physical locations or digital resources but do not inherently provide the specialized security features of an HSM. Thus, the Hardware Security Module stands out as the primary choice for managing the physical security of hardware.
