This detection rule identifies events where an application is linked to a Dropbox team account. It evaluates actions related to linking applications through the Dropbox API and generates alerts based on specific conditions. The rule differentiates between applications linked by team members and personal applications linked by non-team members. If a team member links an app intended for team use, a low severity alert is generated, indicating expected usage. However, linking by non-team members yields a high severity alert, prompting immediate investigation into the legitimacy of the access. The rule is equipped with multiple test cases to verify scenarios involving expected and unexpected app linkages, thereby ensuring thorough monitoring of application integrations with team accounts. It mandates verification of application legitimacy and immediate follow-up on suspicious activities, emphasizing the importance of maintaining security around team assets.
