The last couple of years we have seen several security breaches in IT, leading to serious impact and financial losses. Not only in the United States, but also in the rest of the world.

Previously, MVP Nicolas Blank wrote an interesting article "Having an Identity Crisis" and it talked about all kinds of attacks on your environment.

Almost a year ago, in March 2020, I wrote an article called Microsoft stops basic authentication, now what on this site about Microsoft’s plan to decommission Basic Authentication in Office 365.
