I read an article regarding flaws in a security system in a jail. After a power surge the guards were surprised to find all of the cells on death row opened. They did some investigating and found that the security system could be manipulated to actually control these cells and possibly release inmates. These findings were due in part to the fact that guards were not following proper protocol when it came to using computer stations which controlled the closing and opening of cell doors.
This fortifies my beliefs that no matter how good your security system is it is only as good as your weakest link. Most of the time the biggest security flaws come from human error. Something as simple as a guard checking his e-mails on a computer which is connected to the cell doors could have led to a cyber intruder gaining control of those very same cell doors keeping dangerous inmates under control.
I find that the more complex security systems are the easier it is for problems to arise and human error to become an issue. Proper training and direction trumps complexity from my personal experience in several jobs. A security engineer had this to say regarding security procedures: “If the prisons change their security procedures, they could probably fix the problem 98 percent on their own.”
