SharePoint: Agent chat web part

🚨 The Signal: SharePoint now supports a new web part for embedding M365 Copilot agents directly onto modern pages. This introduces new vectors for data exposure and prompt injection risks.

The Impact

SharePoint administrators and security teams are affected by new risks related to agent configuration and data exposure.

• SharePoint Admins: Must configure agent permissions carefully to prevent unauthorized data access.
• Security Teams: Need to monitor agent interactions for prompt injection and sensitive data leakage.
• Content Owners: Must understand how agents access and summarize their content, ensuring accuracy.
• End Users: May inadvertently expose sensitive data through agent interactions if not properly trained.

The Action

1. Review and restrict permissions for M365 Copilot agents within SharePoint sites and libraries.
2. Implement data loss prevention (DLP) policies to monitor agent interactions for sensitive information.
3. Educate users on responsible interaction with AI agents and potential data exposure risks.
4. Establish a governance framework for Copilot agent deployment and content access within SharePoint.
5. Regularly audit agent logs and user interactions for anomalous behavior or policy violations.
