It aims to preserve authorized collaboration while controlling who can discover, access, change, download, redistribute, retain, or delete information throughout the sharing lifecycle.
Controls should reflect the file’s classification, business owner, intended recipients, collaboration context, and retention needs. Secure defaults, named recipients, least privilege, link expiration, guest reviews, audit trails, and prompt revocation reduce unintended exposure, but teams must also manage synchronized and downloaded copies.
Key points
Access and sharingPrefer authenticated, attributable recipients and least-privilege permissions; constrain anonymous links, external guests, public discovery, resharing, and bulk download according to risk.
LifecycleAssign ownership, classify information, review memberships and links, expire temporary access, preserve required records, and dispose of files and residual copies under policy.
Services and endpointsConfigure collaboration tenants and network shares securely, monitor unusual access, and protect endpoints, synchronization clients, application integrations, and recovery copies.
Important limitationControls on a repository may no longer apply after an authorized recipient downloads, screenshots, synchronizes, or republishes a file. Logging records activity but does not itself prevent disclosure or misuse.
