Microsoft Enhances Teams Security to Block Unwanted Bots
Microsoft introduces new administrative measures to prevent unauthorized bots from joining Teams meetings
Administrative controls for external bot management
Administrators can deploy this policy via the Teams Admin Center, applying it to individual users or defined groups. Once activated, the policy identifies bot activity, routes such entities to a waiting area, and alerts meeting organizers to approve their participation.
\”Even in scenarios where organizers permit participants to bypass the waiting area, bot detections through this policy will still necessitate explicit approval before entry,\” stated Meera Ajam, Senior Product Marketing Manager at Microsoft.
The policy also features an option to disable bot detection.
Bot identification methodologies
Teams now leverages behavioral analytics and infrastructure-based signals to improve bot detection accuracy. Microsoft is launching the Teams Bot Identification Program, enabling independent software vendors (ISVs) developing meeting integrations for Teams to participate.
The company is currently collaborating with a select group of ISVs to test the feature and refine its implementation before broader deployment.
When Teams recognizes a bot, a visual marker is displayed to differentiate it from human participants, aiding organizers in decision-making during the waiting phase.
Participants are categorized into Verified, Standard, and Bot groups within the waiting area. The platform has implemented safeguards to minimize accidental bot admissions. These include eliminating the one-click admission option for detected bots, displaying confirmation alerts when bot activity is present during admission, and notifying organizers if they choose to admit all participants when bots are included.
Future enhancements
Microsoft plans to expand administrative capabilities, including the introduction of approved bot allowlists, organization-wide restrictions on external bots, detailed reporting and audit trails for bot activity, and more precise controls to address varying security requirements.
