Answer overview

This solution utilizes an event-driven architecture to supply agility while reducing manual administration effort.

Architecture

This solution enables automated controls management using event-driven architecture with AWS Services such as for example AWS Audit Supervisor, AWS Lambda and Amazon S3, in integration with code management services like &lt and GitHub;a href=”https://aws.amazon.com/codecommit/” focus on=”_blank” rel=”noopener noreferrer”>AWS CodeCommit. The Regulates owner can style, manage, monitor and roll out custom regulates in GitHub with a straightforward custom controls configuration document, as illustrated in Determine 1. After the controls configuration document is placed within an Amazon S3 bucket, the on-commit occasion of the document triggers a manage pipeline to load settings in audit manager utilizing a Lambda functionality.

Option workflow overview

  1. The Manage owner loads the controls as code (Settings and Framework) into an Amazon S3 bucket.
  2. Uploading the particular Controls yaml file in to the S3 bucket triggers the Lambda function to procedure the control document.
  3. The Lambda function processes the Handles file, and creates a fresh control (or updates a preexisting control) in the Audit Supervisor.
  4. Uploading the particular Controls Framework yaml document in to the S3 bucket triggers the Lambda function to procedure the Controls Framework document.
  5. The Lambda function validates the Regulates Framework file, and updates the Settings Framework library in Audit Supervisor

This solution could be extended to generate custom frameworks in line with the controls, also to run an assessment framework contrary to the controls.
