To ensure that CloudTrail cannot be disabled in any member account, the control must be enforced above the individual accounts, at the organization level , and must not be overridable by local administrators. AWS Service Control Policies (SCPs) provide exactly this capability: they define permission guardrails that apply to all IAM users, roles, and even the root user in accounts within an AWS Organizations OU.

By applying an SCP that explicitly denies cloudtrail:StopLogging and cloudtrail:DeleteTrail , the organization prevents any principal in the affected accounts from disabling logging or deleting the trails, regardless of their IAM permissions. This provides strong, centralized enforcement of audit logging.

Option B uses IAM policies in each account. Local administrators with sufficient privileges could modify or detach those policies, defeating the control. Option C only sends notifications and does not prevent the action. Option D with AWS Config auto-remediation still allows a window where CloudTrail is disabled and also can be disabled or modified itself.

Therefore, the most robust and least bypassable approach is to use an SCP at the OU level to deny CloudTrail stop and delete actions.

Running unit tests in the build phase and aborting on failure (OnFailure=ABORT) prevents deployment if tests fail.

AWS CDK assertions module provides programmatic unit tests against synthesized templates (Option D).

The --rollback flag relates to CloudFormation stack rollback, not test gating.

The --require-approval flag controls manual approvals, not test outcomes.

cdk diff checks for changes but is not a unit test and may not catch logical errors.

A. The CloudFormation template should be modified to include a parameter that indicates the location of the .zip file containing the Lambda function ' s code. This allows the CloudFormation deploy action to use the correct artifact depending on the region. This is critical because Lambda functions need to reference their code artifacts from the same region they are being deployed in. B. You would also need to create a new CloudFormation deploy action for the us-east-1 Region within the pipeline. This action should be configured to use the CloudFormation template from the artifact that was specifically created for us-east-1.
