If you were to check the dictionary definition of enumerate, it means to count something one by one.
How could this be a bad thing?
Well, when we have attackers performing reconnaissance against our infrastructure, they will be counting
your users one by one.
The groups, one by one, the shares you have one by one, they are going to gain as much information
as possible through this process called enumeration.
We are going to take and look at enumeration in detail and see protocols that are often enumerated against
to learn an awful lot about our infrastructure.
