Microsoft Teams: Collaborate using Pages in Channels

🚨 The Signal: Microsoft Teams channels now support Pages, allowing direct creation and collaboration on web-based content. This expands content creation surfaces within Teams, potentially increasing unmanaged information sprawl and data exposure risks.

The Impact

All Teams users are affected by new content creation capabilities, increasing the risk of unmanaged data and potential information exposure.

• End Users: Can create new content, increasing potential for unclassified or sensitive data.
• Admins: Need to manage new content types and locations, increasing governance overhead.
• Security Team: Faces increased risk of data sprawl and unmanaged sensitive information.
• Compliance Team: Must adapt policies to cover new content creation surfaces within Teams.

The Action

1. Review existing SharePoint site creation policies to ensure they apply to Pages created in Teams.
2. Communicate to users best practices for creating and storing sensitive information within Teams.
3. Evaluate Microsoft Purview Data Loss Prevention (DLP) policies for SharePoint and Teams to ensure coverage of new Page content.
4. Consider implementing sensitivity labels for Teams channels and associated SharePoint sites to classify content.
5. Monitor Microsoft 365 audit logs for Page creation and modification activities within Teams channels.
