HSM stands for hardware security module, which is a physical device that is used to store and manage cryptographic keys in a secure and tamper-resistant manner. HSMs can provide high-performance encryption and decryption operations, as well as key generation, backup, and recovery. HSMs can also prevent unauthorized access or extraction of the keys, even by the cloud service provider or the HSM vendor. HSMs can enhance the protection of a critical environment that is used to store and manage encryption keys for a financial institution or any other organization that deals with sensitive data.
