The Box Shield Suspicious Alert Triggered rule is designed to detect high-risk user login events or session events flagged by Box Shield as potentially suspicious. When a user accesses Box from a location deemed suspicious or exhibits behavior associated with compromised accounts, this rule is triggered, enhancing the vigilance against initial access attacks by utilizing detection mechanisms aligned with the MITRE ATT&CK framework, specifically T1078 - Valid Accounts. The rule relies on the Box.Event logs to identify and assess user access patterns based on risk scores assigned to events. When a user logs in from unusual locations or there are irregular session behaviors, the events will receive an evaluation based on pre-defined severity thresholds.
