(Updated) Microsoft Teams: Quick Share for images

🚨 The Signal: Microsoft Teams now offers 'Quick Share' for images, enabling faster sharing and link copying. While existing permissions apply, this increases the velocity of content distribution, potentially raising data sprawl risks if not managed by existing DLP policies.

The Impact

All Teams users are affected by easier image sharing, posing a low security risk if existing data loss prevention (DLP) policies are not comprehensive.

  • End Users: Can share images and links faster, increasing potential for accidental oversharing.
  • Security Teams: Must ensure existing DLP policies adequately cover image sharing scenarios.
  • Data Owners: Increased risk of sensitive image data being shared inappropriately if not classified and protected.
  • Compliance Teams: Need to verify that data handling policies account for accelerated image sharing.

The Action

  1. Review existing Microsoft Purview Data Loss Prevention (DLP) policies to ensure they adequately cover image content in Microsoft Teams.
  2. Verify that sensitivity labels are correctly applied to sensitive images and that DLP policies enforce appropriate sharing restrictions.
  3. Educate users on responsible sharing practices for images within Microsoft Teams, reinforcing existing data governance policies.
  4. Monitor Microsoft Purview audit logs for unusual image sharing activities or policy violations related to Teams.
