This detection rule is designed to identify changes in MongoDB user roles, which could indicate unauthorized access or privilege escalation. When a user role is modified, an event is generated and logged under the MongoDB Organization Event log type. The rule will flag any occurrence where user roles change, with a focus on distinguishing legitimate administrative actions from potential malicious activity. It includes a deduplication period of 60 minutes to minimize repeated alerts for the same event. The expected result for significant changes in user roles is set to true, while other unrelated events should not trigger alerts. The severity of this alert is classified as low, acknowledging that while role changes may not always indicate a security concern, they warrant monitoring. The rule integrates with a system that can detect and log user role changes based on predefined criteria, leveraging the comprehensive fields available within MongoDB logging.
