Microsoft Copilot (Microsoft 365): Seamless Search and Chat Integration

🚨 The Signal: Microsoft 365 Copilot Search now integrates conversational AI, allowing users to chat directly with search results. This unifies information retrieval and content generation, potentially exposing sensitive data through new interaction vectors.

The Impact

All users are affected, increasing the risk of sensitive information exposure and unauthorized data synthesis.

• End users: Increased risk of inadvertently exposing sensitive data through conversational prompts.
• Security teams: New challenge in monitoring and auditing data access and synthesis via Copilot chat.
• Data owners: Potential for unauthorized aggregation of sensitive information from disparate sources.
• Compliance officers: Difficulty in demonstrating adherence to data handling and privacy regulations.

The Action

1. Review and refine Microsoft Purview Data Loss Prevention (DLP) policies to include Copilot interactions.
2. Implement and enforce sensitivity labels for all sensitive documents accessible by Copilot.
3. Educate users on responsible prompting and the risks of sharing sensitive information in Copilot chats.
4. Monitor Copilot usage logs for unusual data access patterns or synthesis activities.
5. Assess and update existing information governance policies to specifically address AI-driven content generation and chat.
