You Give Me Security

Welcome to the final part of this 3 part series; Previous articles dealt with firstly Creating the Azure Infrastructure, and then creating the .NET Service code necessary to connect to a Microsoft 365 mail box that has been secured using 2 factor Authentication. Finally, but very definitely most importantly… We must secure the App Registration we created earlier. Now at the moment this particular set of credentials can be used to plough through absolutely anybody’s email account which is a massive security risk. The best thing that we can do to reduce the surface attack area is to limit these credentials so that they can only be used against certain mail accounts.
