Creating Secrets Using Best Practices Overview Domain expertise for creating and managing secrets in AWS Secrets Manager with production-grade security controls: KMS encryption, automatic rotation, least-privilege IAM policies, CloudTrail auditing, and lifecycle management. Create a secret with best practices To create a properly secured secret in AWS Secrets Manager, follow the procedure exactly. See secret creation procedure . The procedure supports four secret types: database credentials, API keys, OAuth tokens, and custom secrets. Each type is structured appropriately and encrypted with a dedicated KMS key. Troubleshooting KMS key access issues Verify the IAM principal has kms:CreateKey and kms:PutKeyPolicy permissions, and that the key policy grants kms:GenerateDataKey , kms:Decrypt , and kms:DescribeKey scoped with kms:ViaService to secretsmanager..amazonaws.com . See the full procedure for details. Rotation setup failures Check that the Lambda rotation function exists, has proper permissions, and can reach the target system. Review CloudWatch logs for the rotation function. Secret access denied Verify the IAM policy is attached to the correct principal, the KMS key policy allows decryption (and kms:GenerateDataKey for write/rotation), and the principal is using HTTPS. See the full procedure for details.
