Automate scheduled reviews of Drive permissions

Run regular audits of shared file and folder permissions using a delegated service account to catch over-sharing before it becomes a risk.

The problem

Drive sharing gets out of hand quickly, especially when users are free to add external collaborators. Manual checks are rare, so over-exposed documents persist for months. Auditors and compliance teams need evidence that reviews are happening on a schedule.

How it works

  1. Delegate domain-wide Drive read access to a service account.
  2. Schedule a job to list all shared files and enumerate each file's permissions.
  3. Filter for files shared outside the domain or with public links.
  4. Generate a report and notify relevant owners or compliance contacts.
  5. Track changes over time to flag newly exposed files.

What changes

You get a repeatable, timestamped audit trail of Drive sharing, and actionable alerts for risky exposures without relying on users to self-report.

The trap in this one. The Drive API's permissions list endpoint can lag behind recent sharing changes by several minutes, especially for large folders. If you run the review immediately after a permissions change, your report may miss or misclassify recent exposures—always allow for propagation lag, and never treat the output as real-time. Also, files in Shared Drives with inherited permissions may not appear in user-centric listings, so cross-check both file and drive-level permissions.

Questions people ask

How do I identify public or external shares?

Check each permission object for 'anyone' or 'domain' type with 'reader' or 'writer' role, and compare email addresses against your domain list to flag externals.

How often should permission reviews run?

Monthly is typical for most domains, but high-risk environments may need weekly checks. Balance frequency against API quotas and the volume of alerts.
