How to Automate Permissions Review in AWS IAM Identity Center?

Step 1: Define Review Policies

Review policies associated with critical actions and sensitive resources. Consider policies granting broad access and those affecting compliance.

Step 2: Leverage AWS Config for Tracking Changes

AWS Config records changes to resources over time. Use it to track alterations in AWS IAM policies and permissions.

Step 3: Set Up Amazon CloudWatch Events for Triggers

Configure Amazon CloudWatch Events to trigger the review process at scheduled intervals, ensuring periodic checks.

Step 4: Use AWS Lambda for Automation

AWS Lambda allows you to run code in response to events. Use it to automate the permissions review process triggered by Amazon CloudWatch Events.

Step 5: Implement Custom Scripts for Detailed Validation

Implement custom scripts within AWS Lambda functions to perform detailed validation based on your organization’s specific requirements.

Benefits of Automated Permissions Review

  • Proactive Risk Management: Automated reviews allow organizations to proactively identify and rectify potential security risks.
  • Time and Resource Savings: By automating the review process, organizations save time and resources, which can be redirected toward strategic initiatives.
  • Enhanced Compliance: Continuous, automated reviews ensure that permissions align with compliance standards without manual efforts.
