How to implement single-user secret rotation using Amazon RDS admin credentials

Security Blog

This article provides a walkthrough on how to implement a modified alternating-user rotation strategy for Amazon RDS database user credentials using AWS Secrets Manager. This strategy helps meet security and compliance standards that prevent a database user from changing their own credentials and having multiple users with identical permissions.

Specifically, the article covers:

  • Configuring alternating-user rotation on the database credential secret
  • Modifying the Lambda rotation function to implement the modified rotation strategy
  • Testing the modified rotation strategy and verifying the secret was rotated without creating a _clone user
  • Cleaning up the resources
