Microsoft Copilot (Microsoft 365): Copilot Cowork for Government Clouds

🚨 The Signal: Copilot Cowork, an AI agent capable of delegating and executing tasks based on user intent and M365 data, is now available in GCC. This introduces autonomous AI capabilities, increasing data exposure and the attack surface.

The Impact

All GCC users are affected, with a high security risk due to autonomous AI access to sensitive data and potential for misuse.

• Security Teams: Risk of data exfiltration and unauthorized access by autonomous agents.
• Compliance Teams: New challenges in auditing AI actions and maintaining data sovereignty.
• End Users: Potential for over-delegation or unintended data exposure through AI actions.
• Admins: Increased complexity in managing AI permissions and monitoring agent activities.

The Action

1. Review and update data governance policies for AI agent access to sensitive information.
2. Implement strict access controls for Copilot Cowork, limiting its scope to necessary data.
3. Establish monitoring and auditing mechanisms for AI agent activities and data interactions.
4. Educate users on responsible delegation to Copilot Cowork and potential data exposure risks.
5. Regularly review Copilot Cowork's permissions and data access logs for anomalies.
