The rule 'AWS EnableRegion Command Monitoring' is designed to detect the invoking of the EnableRegion command within AWS CloudTrail logs. AWS encompasses various regions, with only some being enabled by default while others necessitate explicit enabling per account. This monitoring capability is crucial for identifying potential security threats where adversaries might leverage the EnableRegion command to create pathways for ongoing access and operational continuity within the AWS infrastructure. The rule captures instances where accounts enable new regions that might not be covered by existing security measures, signaling possible persistence mechanisms. This can help organizations strengthen their AWS security posture by identifying and mitigating unauthorized region enabling actions.
