    ATT&CK techniques: Indicator Removal (T1070) Impair Defenses (T1562) Data Manipulation (T1565) Impair Defenses: Disable or Modify Cloud Logs (T1562.008)
    Required data: Google Workspace Audit Logs
    Detector tags: Google Workspace
    Attacker's goals: Adversaries may stop audit log events from being sent to remove evidence of their presence or hinder defenses.
    Investigative actions: Check if the identity intended to perform this action or look for signs that the user account is compromised (e.g. abnormal logins, unusual activity). Check whether Google Workspace audit log events were configured to be sent to Google Cloud. Follow further actions done by the account.
