Question
Which AWS service should be used to store database credentials with the highest security?
A. AWS Identity and Access Management (IAM)
B. AWS Secrets Manager
C. Amazon S3
D. AWS Key Management Service (AWS KMS)
Answer
B. AWS Secrets Manager
Explanation
AWS Secrets Manager should be used to store database credentials with the highest security. It securely stores, encrypts, rotates, and retrieves secrets such as credentials, passwords, and API keys.
AWS Secrets Manager is specifically designed to securely store, manage, and retrieve sensitive information such as database credentials, API keys, and other secrets. It offers several key features that make it the most secure option for this purpose:
Secure Storage and Encryption
- Secrets Manager encrypts secrets using AWS Key Management Service (KMS). By default, it uses a managed key (aws/secretsmanager) or allows users to specify their own customer-managed keys for encryption.
- This ensures that sensitive data remains encrypted both at rest and in transit.
Automatic Rotation of Secrets
- It supports automatic rotation of secrets without requiring changes in application code. For example, database credentials can be rotated regularly using a Lambda function created by Secrets Manager.
- This reduces the risk of credential compromise by minimizing their exposure time.
Centralized Management
- Secrets Manager provides centralized control over secrets, making it easier to manage access permissions using fine-grained IAM policies.
- This reduces the complexity of managing credentials across multiple applications or environments.
Secure Retrieval
- Applications can retrieve credentials dynamically at runtime via API calls to Secrets Manager. This eliminates the need for hardcoding sensitive information in source code or configuration files, significantly improving security.
Audit and Monitoring
- Integration with AWS CloudTrail allows for logging and auditing of secret access and management activities, ensuring compliance with security standards.
Multi-Region Replication
- For disaster recovery and resilience, Secrets Manager supports multi-region replication of secrets.
Why Not the Other Options?
A. AWS Identity and Access Management (IAM): IAM is used to manage user permissions and access policies but does not store or rotate sensitive credentials like database passwords.
C. Amazon S3: While S3 can store data securely, it is not designed for managing secrets or automating credential rotation.
D. AWS Key Management Service (AWS KMS): KMS provides encryption key management but does not handle secret storage or rotation directly. It works in conjunction with services like Secrets Manager for encrypting secrets.
AWS Secrets Manager is the optimal service for securely storing database credentials due to its robust features like encryption, automated rotation, fine-grained access control, and secure retrieval mechanisms.
