AWS Security Automation is a collection of scripts and resources designed for DevSecOps, security automation, and automated incident response remediation within AWS environments. The toolkit includes several key components: IAM Access Denied Responder automatically responds to access denied events occurring within CloudTrail events, failed AWS console authentication attempts, or Client.UnauthorizedOperation events through automated workflows. EC2 Auto Clean Room Forensics provides automated incident response capabilities by taking instance IDs from SNS topics and coordinating through AWS Lambda functions and Step Functions to automatically notify stakeholders, isolate compromised instances, and perform basic forensic analysis. CloudTrail Remediation offers demonstration scripts for automatically restarting CloudTrail logging with built-in placeholders for forensic procedures to prevent re-enabling CloudTrail without proper investigation of the root cause. Force User MFA includes demonstration scripts that automatically create and attach virtual multi-factor authentication to newly created IAM users, allowing users to retrieve MFA seeds through AWS CLI. The solution leverages AWS native services including Lambda, Step Functions, SNS, and CloudTrail to provide automated security response capabilities for common AWS security scenarios.
