Microsoft Teams Room Architecture: Private and Shared Channels in Teams
Strategies for the use of Teams
If we consider only the aspects of security and relevance, this scenario is obviously not viable and does not at all meet the requirement for a purely internal exchange of content. What about when we consider the use of "private channels"?
This scenario requires discipline! It would be best if you subjected completed projects and the associated internal and external releases to regular review.
Otherwise, it is difficult to ensure that the parties do not exchange sensitive ones. The security aspect is also the decisive factor here. All project members meet at least in the "general" channel increases the risk of unintentional data loss.
An often asked question is: "Can we hide the General Channel?" Unfortunately, the answer to this is no!
But, it is possible to restrict the permissions to send messages in the "General" channel to the team's owners. You can also configure this for the storage of documents within the channel.
The security challenge is solved with shared channels within this scenario. However, there remains the organizational challenge of regularly reviewing the existing project channels and deciding whether content and approvals are still needed.
Overall, as you have no doubt noticed, this is not a fully comprehensive look at the topic of security in the Microsoft Teams environment. Microsoft 365 offers a variety of additional capabilities that should be incorporated into the architecture of team rooms, for example:
- Consideration of B2B Direct Access configuration, which makes shared channels for cross-organizational sharing possible in the first place.
- Library, folder, and document level permissions
- Use of sensitivity labels and Microsoft Information Protection (MIP)
- Use of Data Loss Prevention (DLP)
- Capabilities for automatic expiration of shares and permissions
