The AWS RDS Cluster Creation rule is designed to detect the unauthorized creation of Amazon RDS Aurora DB clusters or global databases across multiple regions. Given that RDS facilitates streamlined database management, attackers could exploit this capability to establish persistent access or exfiltrate data by creating unauthorized clusters. The rule triggers alerts on successful creation events of RDS clusters, allowing security teams to investigate potential misuse, cross-reference user identities, and observe associated network activity to ensure operations remain compliant with expected behaviors. False positives may arise from legitimate administrative actions, automated scripts, or routine operational tasks, warranting careful review and potential exclusion based on known patterns. The rule encourages thorough investigation steps, including reviewing AWS CloudTrail event details, verifying user identities, checking event timestamps for unusual activity, and evaluating the configurations of newly created clusters to identify any security misconfigurations. Immediate response measures include isolating the suspicious cluster, auditing IAM accounts involved, and strengthening monitoring capabilities for future RDS-related actions, alongside updating IAM policies to reflect the principle of least privilege.
