I'm a liar. So are you. The funny part is, we all know it. A new study by Cisco just confirms it. The 10-word version: "Everyone breaks published security policy to get their job done." None of this is a surprise to your IT department. We long for the day we can punish problem users for violating the pages of acceptable-use policies they signed but never read their first day on the job. Please, please, please just let us ban one guy from the network — pour encourager les autres , as Voltaire said.
