[THEME] Teams
The Teams theme optimizes the security configuration of Microsoft Teams. Teams is a central hub for corporate communication and file sharing, making it an attractive target for attackers.
What does Attic do?
Attic checks the security settings of Microsoft Teams to ensure that data sharing and meeting access are properly restricted.
The checks in this theme cover:
- External storage providers are disabled in Teams
- Teams channels cannot receive email from external sources
- Consumer inbound communication restrictions
- Anonymous users cannot start meetings
- Anonymous users cannot join meetings without approval
- Messages are scanned for unsafe links
- Messages are scanned for unsafe files
- Users can report security concerns
Why is this important?
Teams contains a wealth of sensitive corporate data including chat messages, shared files, meeting recordings, and internal discussions. Misconfigured Teams settings can allow unauthorized external access, malware distribution via messages, or data leakage through uncontrolled file sharing. Securing Teams protects one of your most used collaboration tools.
