Document & Data Classification Guide Page (for Google Drive) A framework for classifying documents by sensitivity, and applying it in Google Drive. The three tiers Tier What Examples Sharing Low Public or public-ready Blog posts, marketing, published reports Anyone with the link is fine Medium Internal, not secret Meeting notes, draft strategy, budgets pre-approval Named people or internal group only; no link sharing High Confidential, regulated, or PII SSNs, financial/payroll data, health info, donor/client records, credentials, HR files Named individuals only, reviewed periodically; no link sharing Quick test: Would it place someone at risk if it leaked? If so, it should be at least Medium . Does it contain PII, financial, health, or credential data? It shoul be High . Is it meant to be public? Make it Low . Applying Tiers to Google Drive Naming: tag files/folders so sensitivity is visible at a glance, e.g. [H] Donor Contact List . Folders: separate top-level folders per tier ( Public/ , Internal/ , Confidential/ ) rather than mixing tiers in one folder. Restrict access at the folder level for Confidential/ . Sharing settings: Tier Link sharing Editors Low On Few editors, open viewing Medium Off Named editors/viewers High Off, access reviewed regularly Minimal editors; disable download/print/copy for viewers where possible Review: quarterly, check who still has access to Confidential/ files, flag any "anyone with the link" shares that should be tighter, and sort anything sitting untagged in a misc folder. If overshared: fix the sharing setting immediately, move the file to the right folder, and flag it to whoever owns incident response if High-sensitivity data was exposed.
