Terms in this definition
- Microsoft Purview Data Loss Prevention
Policies in Purview that look for sensitivity labels or sensitive information types in content held in many places, including Microsoft 365 Copilot, and respond by auditing, warning or blocking. You can simulate a policy before enforcing it.
- Exclusions
Scopes taken out of a policy assignment; they can only narrow its coverage, never widen it.
- Dashboard
Page in VCF Operations built from widgets that display object metrics, properties, alerts and relationships. Predefined and custom dashboards exist, and either kind can be shared.
Related terms
- Auto-labelling policy
A Purview policy that labels content without user involvement: documents stored in SharePoint and OneDrive and messages passing through Exchange. It is tested in simulation mode before being turned on, and unlike labelling in the Office apps it cannot just suggest a label.
- Service-side labelling
Labelling applied automatically within Microsoft 365 services by an auto-labeling policy, covering stored files in SharePoint and OneDrive and email as it passes through Exchange. Policies run in simulation mode first.
