Separation of duty is one of the most powerful tools an information security professional has. But that is exactly what it is: a tool; not a goal.
My family and I live in a very safe suburban neighborhood. The incorporated village has its own police force, and most of the village's budget is spent on it. Much to my surprise, we have been becoming more and more aware of suspicious activities in a house in our area; cars pull up at the strangest hours and leave again within 5 minutes. Usually someone walks over from the car to the house, a handshake is exchanged and the visiting party leaves. Sounds like there is some trade in "stuff" going on.
As with most people, we are not too happy that this is happening on our doorstep. We have repeatedly called the local police department and even had house visits by detectives who were trying to figure out, from our witness statements, what might be going on. The last house visit ended with the detectives reassuring us to call whenever.
