This detection rule identifies potentially unauthorized access to Box enterprise events triggered by unknown or external users. It specifically monitors events logged by the Box cloud service to determine whether a user's activity is expected based on their recognized profile. If an event such as PREVIEW is triggered by an unidentified user, it raises an alert, indicating possible exfiltration or external manipulation. Additional context is provided via the user's IP address and event details. The rule is currently disabled and requires further configuration to activate it for real-time monitoring.
