AWS Secrets Manager

AWS Secrets Manager is a service that helps you protect access to your applications, services, and IT resources without the upfront investment and on-going maintenance costs of operating your own infrastructure. Secrets Manager enables you to easily rotate, manage, and retrieve database credentials, API keys, and other secrets throughout their lifecycle.

Key Features

• Secret Rotation: Automate the rotation of secrets such as database credentials and API keys to reduce the risk of compromise.
• Secure Storage: Store secrets securely using encryption and manage access via AWS Identity and Access Management (IAM).
• Access Control: Use fine-grained access controls to manage who can access or modify secrets.
• Integration with AWS Services: Easily integrate with other AWS services such as RDS, Redshift, and Lambda for managing secrets.
• Audit and Monitoring: Track and monitor access to secrets using AWS CloudTrail and integrate with AWS CloudWatch for alerts.

Common Use Cases

• Database Credentials: Manage and rotate database credentials securely without embedding them in your code or configuration files.
• API Keys: Store and manage API keys and credentials for third-party services securely.
• Application Secrets: Securely manage application secrets and sensitive configurations such as OAuth tokens and encryption keys.
• Compliance and Security: Meet compliance requirements and enhance security by rotating secrets regularly and securely managing access.
• Integration with CI/CD: Use Secrets Manager with CI/CD pipelines to manage deployment secrets and access credentials securely.
