   If you have responsibility for security and/or access management for an organization, then there is a "simple" request that you have received, and will always receive... Users request local admin access to systems.

   Most of you know what I mean.  I'm referring to the local administrator or root account on a system.  When a person has local admin, they can access any part of the system, change or disable settings (including deactivating anti-malware or other security software), and, perhaps most importantly, install and run any software.  This last item is probably the primary reason people request this level of access.

   But there is another category of internal issues... accidents.
