OneDrive: Refreshed Libraries View in OneDrive Web

🚨 The Signal: OneDrive Web's 'More places' is replaced by a 'Libraries' view, showing more recently accessed libraries and Teams/SharePoint sites. This enhances content discovery but increases potential exposure of sensitive data if permissions are not correctly managed.

The Impact

All users are affected by improved content discovery, which increases the risk of inadvertent data exposure if access controls are not properly configured.

• End users: Easier access to shared content, increasing risk of oversharing.
• Security teams: Heightened need to audit and enforce data access policies.
• Admins: Must ensure SharePoint and Teams site permissions are least privilege.
• Compliance officers: Increased visibility of content necessitates stricter data classification.

The Action

1. Review SharePoint site permissions for all document libraries to ensure least privilege access.
2. Audit Microsoft 365 Groups and Teams private channels for appropriate membership and access levels.
3. Implement or refine Microsoft Purview Information Protection policies for sensitive data labelling and access control.
4. Educate users on data handling best practices and the implications of sharing content.
