Description

SSE-KMS provides server-side encryption where AWS Key Management Service (KMS) manages the encryption keys. It offers additional security and audit capabilities by integrating KMS with Amazon S3 for encryption.

Features

• Enhanced Security: Uses KMS to manage encryption keys with additional security controls.
• Key Rotation: Supports automatic key rotation to enhance security.
• Access Control: Integrates with IAM and KMS policies for fine-grained access control.
• Audit: Provides detailed key usage logs through AWS CloudTrail.
• Integration: Seamlessly integrates with Amazon S3 and other AWS services.

Limitations

• Cost: Incurs additional costs for KMS key usage and management.
• Latency: Potential for increased latency due to KMS key management operations.
• Complexity: Requires configuration and management of KMS keys and policies.
• Service Limits: Subject to AWS KMS usage limits, which may impact scalability.

Use Cases

• Regulatory Compliance: Encrypting data in S3 to meet stringent regulatory requirements with detailed audit logs.
• Secure Backups: Encrypting backup data stored in S3 using managed keys with automatic rotation and auditing.
• Data Protection: Ensuring sensitive data in S3 is encrypted using keys managed by KMS for enhanced security and compliance.
