Guide: AWS KMS Integration
What is AWS KMS Integration: AWS Key Management Service (KMS) is a managed service that allows you to create and control the cryptographic keys used to encrypt your data. The integration of AWS KMS with other AWS services enables secure control over the data handled by these services.
Why it is important: AWS KMS integration ensures the security of your AWS workloads. By providing centralized control over cryptographic keys, it aids in meeting compliance requirements. It also enables encryption across multiple AWS services, enhancing the overall data security.
How it works: When an AWS service is integrated with AWS KMS, it uses KMS APIs to generate, use, rotate and disable cryptographic keys. This is all accomplished through the AWS Management Console, CLI, or SDKs.
Exam Tips: Answering Questions on AWS KMS Integration: Understanding the key usage, key rotation and permissions associated with AWS KMS are vital for answering exam questions. Always consider AWS KMS best practices and remember that KMS is region-specific. Having a clear understanding of the AWS shared responsibility model and how AWS KMS fits into that model will be beneficial.
Note: While implementing the encryption and decryption of data, remember that KMS keys cannot decrypt data that was encrypted using a different KMS key or through a different method.
