Microsoft Copilot (Microsoft 365): Power BI integration in M365 Copilot

🚨 The Signal: Microsoft 365 Copilot can now access and reason over Power BI data. This expands Copilot's data access, increasing the potential for sensitive information exposure if Power BI permissions are not tightly controlled.

The Impact

All users with Copilot access are affected, increasing the risk of sensitive Power BI data exposure through natural language queries.

  • End users: Risk of oversharing sensitive Power BI data via Copilot.
  • Security teams: Increased surface area for data exfiltration and compliance breaches.
  • Data owners: Potential for unintended disclosure of restricted Power BI content.
  • Admins: Need to review and enforce Power BI dataset permissions rigorously.

The Action

  1. Review all Power BI dataset and report permissions to ensure least privilege is enforced.
  2. Implement data loss prevention (DLP) policies in Microsoft Purview to monitor and restrict sensitive Power BI data sharing.
  3. Educate users on responsible data handling when interacting with Copilot and Power BI data.
  4. Monitor Copilot usage logs for unusual access patterns to Power BI content.
  5. Configure Power BI sensitivity labels to classify and protect sensitive datasets.
