Scan all the EC2 instances for noncompliance with IAM Config. Use Amazon Athena to queryIAM CloudTrail logs for the framework installation

Scan all the EC2 instances with the Amazon Inspector Network Reachability rules package to identity instances running a web server with RecognizedPortWithListener findings

Scan all the EC2 instances with IAM Systems Manager to identify the vulnerable version of the web framework

Scan an the EC2 instances with IAM Resource Access Manager to identify the vulnerable version of the web framework

Use IAM Control Tower. Modify the default Account Factory networking template to automatically associate new accounts with a centrally managed VPC through a VPC peering connection and to create a default route to the VPC peer in the default route table. Create an SCP that denies the CreatelnternetGateway action. Attach the SCP to all accounts except the security inspection account.

Create a centrally managed VPC in the security inspection account. Establish VPC peering connections between the security inspection account and other accounts. Instruct account owners to create default routes in their account route tables that point to the VPC peer. Create an SCP that denies theAttach InternetGateway action. Attach the SCP to all accounts except the security inspection account.

Use IAM Control Tower. Modify the default Account Factory networking template to automatically associate new accounts with a centrally managed transitgateway and to create a default route to the transit gateway in the default route table. Create an SCP that denies the AttachlnternetGateway action. Attach the SCP to all accounts except the security inspection account.

Enable IAM Resource Access Manager (IAM RAM) for IAM Organizations. Create a shared transit gateway, and make it available by using an IAM RAM resource share. Create an SCP that denies the CreatelnternetGateway action. Attach the SCP to all accounts except the security inspection account. Create routes in the route tables of all accounts that point to the shared transit gateway.

Review the IAM CloudTrail event history logs in an Amazon S3 bucket and look for the Terminatelnstances event to identify the federated user from the role session name.

Filter the IAM CloudTrail event history for the Terminatelnstances event and identify the assumed IAM role. Review the AssumeRoleWithSAML event call in CloudTrail to identify the corresponding username.

Search the IAM CloudTrail logs for the Terminatelnstances event and note the event time. Review the IAM Access Advisor tab for all federated roles. The last accessed time should match the time when the instance was terminated.

Use Amazon Athena to run a SQL query on the IAM CloudTrail logs stored in an Amazon S3 bucket and filter on the Terminatelnstances event. Identify the corresponding role and run another query to filter the AssumeRoleWithWebldentity event for the user name.
