Microsoft Copilot (Microsoft 365): Microsoft 365 Copilot - your AI assistant in the GCCH environment

🚨 The Signal: Microsoft 365 Copilot is now generally available in GCC High. This introduces advanced AI capabilities across M365 apps, leveraging large language models and Microsoft Graph for content generation and summarization, significantly impacting data governance and security posture.

The Impact

All users and security teams are affected by new AI capabilities that introduce data governance and potential data exfiltration risks.

• End users: New AI tools may expose sensitive data if not properly governed.
• Security teams: Must implement new policies to manage AI access and data usage.
• Compliance officers: Need to reassess data handling and privacy controls for AI interactions.
• IT administrators: Responsible for configuring Copilot access and monitoring usage.

The Action

1. Review and update data classification and labeling policies to include AI-generated content.
2. Implement Microsoft Purview Data Loss Prevention (DLP) policies specifically for Copilot interactions to prevent sensitive data exposure.
3. Configure Copilot access controls in the Microsoft 365 admin center to restrict usage based on user roles and data sensitivity.
4. Educate users on responsible AI usage, data privacy, and the risks of sharing sensitive information with Copilot.
5. Monitor Copilot usage logs and audit trails for anomalous activity or potential policy violations.
