What type of encryption does AWS Key Management Service (KMS) facilitate?

AWS Key Management Service (KMS) primarily facilitates encryption key management, which involves the creation, storage, and management of encryption keys used to encrypt data. KMS provides a centralized, secure way to manage keys and allows users to define policies for who can use the keys, thereby ensuring data security both for applications and across environments.

While KMS can be utilized in various encryption scenarios, such as both client-side and server-side encryption, its primary function revolves around managing the keys that enable these processes. This means KMS provides the tools for generating and controlling the keys but does not dictate whether the encryption occurs on the client-side or server-side.

The focus on key management is crucial for maintaining compliance and security standards while ensuring that sensitive data can be encrypted and accessed only by authorized users or services. Therefore, the answer accurately encapsulates the role of AWS KMS in the context of encryption.
