Hi,
Microsoft has a blog series about securing our environment. The first one came in December 2018.
For now there is 8 parts released, hopefully part 9 is coming soon.
When almost all functions are out in the open these days, its really important to secure these functions.
Didn’t find a page that have all the links in one place, so decided to make one.
