Managing secrets in Lambda functions
When building serverless applications, we often need to work with sensitive information such as database passwords, API keys, or authentication tokens. Hardcoding these secrets directly in the Lambda function code is a security risk. If someone gets access to the code, they’ll have access to all secrets. Instead, AWS provides a service called AWS Secrets Manager that stores and manages secrets securely.
Why use AWS Secrets Manager?
AWS Secrets Manager helps to protect access to applications, services, and IT resources. Instead of embedding credentials in the code, we store them in Secrets Manager and a Lambda function retrieves them at runtime. This approach offers several benefits:
- Secrets are encrypted and stored securely
- It’s possible to rotate secrets automatically without changing the code
- It’s possible to control who has access to which secrets using IAM policies
- All secret access...
