Review sensitive information and label usage
The data classification Overview page provides snapshots of how sensitive information and labels are being used in your organization. It displays the volume of sensitive data across Exchange, SharePoint, and OneDrive. The view is categorized by sensitive information types, like US Social Security Number, Credit Card Number, and IP Address.
The Overview page can answer questions like:
- What sensitive data is out there?
- What labels are being used the most?
- Is sensitive data being copied or shared outside the organization?
You can complete the following tasks in the overview section:
- Examine the volume and location of sensitive and business critical information.
- Monitor risky activities associated with sensitive information to inform DLP policies.
- Understand label utilization across Microsoft 365 to improve protection and governance policies.
The Overview page includes the following cards:
- Top sensitive info types
- Top sensitivity labels applied to content
- Top retention labels applied to content
- Top activities detected
- Locations where sensitivity labels are applied
- Locations where retention labels are applied
- Azure Information Protection labels summary
Each card, except for the Azure Information Protection labels summary, links to either the Activity explorer or Content explorer, where a more thorough examination of the data can be done.
