Description: KMS (Key Management Service) keys are fundamental tools for managing data security stored in the cloud. These keys allow users to encrypt and decrypt data, ensuring that only authorized individuals or services can access sensitive information. By using KMS, users can create, rotate, and manage encryption keys centrally, simplifying data protection across multiple cloud services. Additionally, KMS provides a detailed log of actions performed with the keys, facilitating compliance with regulations and security audits. The integration of KMS with cloud storage services allows users to apply granular access policies, ensuring that encryption is consistently and controlledly applied. In summary, KMS keys are essential for ensuring the confidentiality and integrity of data in cloud environments, offering a robust and flexible approach to security management.
