A company has a single AWS account with multiple IAM users. The administrator created an IAM policy that allows all users to launch EC2 instances, but only if they use a specific AMI ID (ami-12345678) and a specific instance type (t3.micro).

A company runs a critical application on Amazon EC2 instances behind an Application Load Balancer (ALB). The application processes financial transactions and must store transaction logs in an Amazon S3 bucket. The security team requires that all API calls to AWS services are logged and that the logs are stored in a secure, tamper-proof manner. The team enables AWS CloudTrail to log management events and Amazon S3 server access logs for the S3 bucket. They also enable AWS Config to track resource changes. The compliance team wants to ensure that no one can disable CloudTrail logging or delete the CloudTrail log files. The security engineer proposes a solution using an SCP in AWS Organizations to deny actions that would disable CloudTrail or delete log files. However, the engineer is concerned that the SCP might be applied too broadly and affect legitimate administrative actions. The engineer wants to ensure that only the security team’s IAM role (SecurityAdminRole) can perform these restricted actions, while all other principals (including IAM users, roles, and the root user) are denied. The engineer creates an SCP that denies cloudtrail:StopLogging, cloudtrail:DeleteTrail, and s3:DeleteObject on the CloudTrail S3 bucket. The SCP includes a condition that allows the action if the principal is SecurityAdminRole. However, after applying the SCP, the security team finds that even SecurityAdminRole is unable to stop CloudTrail logging. What is the most likely cause of this issue?
