AWS Audit Manager

• A service that will help you audit your AWS usage on a regular basis in order to simplify risk management and compliance with regulations and industry standards.

• Automates evidence collection for policies, procedures, and activities, as well as the creation of audit reports.

Features

• Centrally manage and upload evidence from on-premises or multi-cloud environments.

• View analytics data for active assessments on the Audit Manager dashboard and quickly identify non-compliant evidence that needs to be remedied.

• Creation of frameworks with standard or custom controls based on your specific internal audit requirements.

• Custom frameworks can also be shared with another AWS account or replicated into another AWS Region under your own account.

• Supports control set delegation to team members to assist you in reviewing related evidence, adding comments, and updating the status of each control.

Concepts

• Assessments

  • An assessment is based on a framework, which is a collection of controls.

  • When you create an assessment, continuous collection of evidence begins.

  • For audit, you or a delegate can review this evidence and add it to an assessment report.

  • An assessment has two states:

    • Active – currently collecting evidence.

    • Inactive – stops collecting evidence.

• Assessment reports

  • Summarizes the evidence that was gathered from an assessment.

  • It also includes links to evidence PDF files.

  • Assessment reports are placed in an S3 bucket.

• Delegations

  • Allows you to delegate a control set to a subject matter expert for review and validation of evidence.

  • In different AWS Regions, an account can be:

    • Audit owner

    • Delegate

  • Delegates are asked by audit owners to review the evidence associated with a control set.

• Framework library

  • Defines the controls and data source mappings for a given compliance standard or regulation

    • Standard Frameworks – prebuilt AWS frameworks

    • Custom Frameworks – frameworks that you own.

  • By creating a share request, a recipient can use your custom framework to create assessments.

• Control library

  • Standard Controls

    • AWS predefined controls.

    • Editing or deleting standard controls is not allowed.

    • You can customize any standard control to meet your specific requirements.
