One of the things that I personally like about Microsoft Teams from an architect’s perspective is that the service leverages existing Microsoft 365 and Azure AD security capabilities. From an Admin’s perspective, the security features available for other Microsoft 365 services such as EXO and SPO are, when relevant, directly applicable to Teams.
Having said this, if you are new to Microsoft Teams you might struggle to get your head around which of the myriad of available controls relate to Teams and whether they fall under the Microsoft 365 or Azure AD administrative umbrellas. To try and help with this I recently created the diagram below to try and position a lot of the “bells and whistles” you might want to consider for a Teams security posture. One point to note is that different customers (or parts of a business) will have different security requirements. But I use this chart as a bit of a cheat sheet to remind me of some of the main components that should/could be considered during the planning stages of a Teams implementation.
Note; As per the slide name this is a “sample” of the capabilities so may not be exhaustive but it works for me as a super high level overview.
Anyway, just thought I’d post this in case this was helpful. I’ll probably bring some of the features mentioned above to life by way of some video demos in future posts.
