A Key Management System (KMS) is a framework used to manage cryptographic keys in a secure manner. It helps organizations generate, store, and distribute keys that are essential for encrypting and decrypting sensitive data. By ensuring that keys are properly managed, a KMS enhances data security and compliance with regulations. KMS solutions often include features like key rotation, access control, and auditing capabilities. These systems can be integrated with various applications and services, such as cloud platforms and databases, to protect information. Effective key management is crucial for maintaining the confidentiality and integrity of data across different environments.
