Tutorial / Cram Notes

AWS Config is a service that enables you to assess, audit, and evaluate the configurations of your AWS resources. It continuously monitors and records your AWS resource configurations and allows you to automate the evaluation of recorded configurations against desired configurations.

To implement AWS Config at scale, you can:

  • Use AWS Organizations to set up AWS Config across multiple accounts and regions simultaneously.
  • Define custom AWS Config rules to evaluate whether your resources comply with your specific compliance requirements.
  • Employ AWS Config conformance packs to deploy a collection of AWS Config rules and remediation actions across an entire organization.

Example:
By creating and applying Config rules, one can enforce that all EC2 instances have a specific tag or that encryption is enabled on all EBS volumes.

AWS Control Tower

AWS Control Tower offers the easiest way to set up and govern a new, secure, and compliant multi-account AWS environment based on best practices. With Control Tower, you can manage your environment at scale by automating the setup of baseline resources, including setting up a multi-account structure using AWS Organizations, enabling centralized logging from AWS CloudTrail and AWS Config, and applying preventive and detective guardrails.

To scale securely with AWS Control Tower, you can:

  • Configure Guardrails to enforce policy compliance.
  • Utilize Account Factory to provision new accounts that automatically comply with your company’s policies.
  • Automate account provisioning using AWS Service Catalog.
