I have started a series on Zero Trust Security model in Microsoft 365. This is being published on Petri. You can read it here.

You can think of Zero Trust as a way of working, wherein you take it for granted that every user and device accessing your environment – in or out the network – to be compromised, and hence, take actions to confirm the validity of each of those.
