Secure secrets storage
AWS Secrets Manager encrypts secrets at rest using encryption keys that you own and store in AWS Key Management Service (KMS). When you retrieve a secret, Secrets Manager decrypts the secret and transmits it securely over TLS to your local environment. By default, Secrets Manager does not write or cache the secret to persistent storage. And, you can control access to the secret using fine-grained AWS Identity and Access Management (IAM) policies and resource-baesd policies. You can also tag secrets individually and apply tag-based access controls. For example, you can tag secrets used in the production environment as “Prod,” and then write an IAM policy to grant access to these secrets only if the requests are coming from within the corporate IT network.
Automatic secrets rotation without disrupting applications
With AWS Secrets Manager, you can rotate secrets on a schedule or on demand by using the Secrets Manager console, AWS SDK, or AWS CLI. For example, to rotate a database password, you provide the database type, rotation frequency, and master database credentials when storing the password in Secrets Manager. Secrets Manager natively supports rotating credentials for databases hosted on Amazon RDS and Amazon DocumentDB and clusters hosted on Amazon Redshift. You can extend Secrets Manager to rotate other secrets by modifying sample Lambda functions. For example, you can rotate OAuth refresh tokens used to authorize applications or passwords used for MySQL databases hosted on-premises. Users and applications retrieve secrets by replacing hardcoded secrets with a call to Secrets Manager APIs, enabling you to automate secret rotation while ensuring applications run without interruption.
Programmatic retrieval of secrets
You can store and retrieve secrets using the AWS Secrets Manager console, AWS SDK, AWS CLI, or AWS CloudFormation. To retrieve secrets, you simply replace plaintext secrets in your applications with code to pull in those secrets programmatically using the Secrets Manager APIs. Secrets Manager provides code samples to call Secrets Manager APIs, also available on the Secrets Manager Resources page. You can configure Amazon Virtual Private Cloud (VPC) endpoints to keep traffic between your VPC and Secrets Manager within the AWS network. You can also use Secrets Manager client-side caching libraries to improve the availability and reduce the latency of using your secrets.
Audit and monitor secrets usage
AWS Secrets Manager enables you to audit and monitor secrets through integration with AWS logging, monitoring, and notification services. For example, after enabling AWS CloudTrail for an AWS region, you can audit when a secret is stored or rotated by viewing AWS CloudTrail logs. Similarly, you can configure Amazon CloudWatch to receive email messages using Amazon Simple Notification Service when secrets remain unused for a period, or you can configure Amazon CloudWatch Events to receive push notifications when Secrets Manager rotates your secrets.
You can use AWS Secrets Manager to manage secrets for workloads that are subject to U.S. Health Insurance Portability and Accountability Act (HIPAA), Payment Card Industry Data Security Standard (PCI-DSS), ISO/IEC 27001, ISO/IEC 27017, ISO/IEC 27018, or ISO 9001.
