The Gsuite Drive Share In External Email rule is designed to detect anomalies related to the sharing of Google Drive or Google Docs files to external email addresses from an internal domain. By analyzing GSuite Drive logs, this rule extracts the source and destination email domains to identify any external sharing activities. This behavior is critical to monitor as it could suggest potential data exfiltration attempts by malicious insiders or attackers. Such actions may lead to unauthorized access to sensitive information, data breaches, and violations of compliance regulations. Implementing this detection mechanism aids organizations in enhancing their cybersecurity posture by enabling early detection and intervention against potential data leaks.
