Key Generation
AWS KMS allows you to create encryption keys, either managed by AWS or by you, the customer. AWS-managed keys are automatically created and managed by AWS, while customer-managed keys are generated and controlled by you. Both types of keys are protected by hardware security modules (HSMs), ensuring their integrity and confidentiality.
Key Storage
KMS securely stores encryption keys within a centralized system, ensuring that they are encrypted at rest using strong encryption algorithms. The service follows best practices for key management, maintaining the security and confidentiality of your keys.
Key Rotation
AWS KMS supports automatic key rotation, allowing you to replace encryption keys periodically. This minimizes the risk of key compromise and guarantees that your data remains securely encrypted. Rotation is managed seamlessly without impacting your applications or data.
Encryption and Decryption
AWS KMS provides easy-to-use encryption and decryption APIs, allowing you to encrypt your data before storing it and decrypt it when needed. Whether you’re securing data at rest in Amazon S3 or Amazon RDS, or encrypting data in transit using SSL/TLS, KMS ensures data confidentiality.
Access Control
AWS KMS allows you to define detailed access control policies for your keys. You can set permissions that specify who can use the keys, what actions they can perform, and under which circumstances. This ensures only authorized users can access and manage your sensitive data.
By offering a range of robust security features, AWS KMS helps to ensure that your data remains secure, accessible only to those with proper authorization.
KMS combines various components—key generation, key storage, key rotation, encryption and decryption, and access control—to ensure the protection of your data. By utilizing KMS, you guarantee that your data remains secure and can only be accessed by authorized users.
Best Practices for Key Management
To ensure the security and efficiency of AWS KMS, it’s important to follow industry best practices for key management. Here are some key recommendations:
Separation of Duties
