2. Privilege Escalation
Insiders who don't have access to target systems or data will often attempt to elevate their access privileges to get at it.

An example would be an IT person with administrative access, says Saryu Nayyar, CEO of Gurucul. He may elevate his privileges for access to data he does not need for his job - for instance, a customer database.

Great Reminders
Jai, these are all great reminders on monitoring priviledged users and other trusted insiders.  The biggest issue I've seen on this topic in my career is the lack of willingness to consider such a user as a potential threat.  Users with nefarious intent may count on that to enable their activities.
