You just got hired at company A and the old administrator is no longer there. Requests start coming through for adding users to the internet restrict group. When you look at the groups none of the names make sense and there is no documentation out there to explain what each group has rights to and what it does. That would raise concern to me. For security how do you know if everyone has the correct rights.
How would you discover what the groups have rights to? Is there a tool out there that will find this information for you?
