PC Security

The vulnerability of high-value computing equipment has always been of great concern to Learning Support Services, and the theft of items is on the increase. The new wave of thefts sweeping the country is not targeting the computers as a whole unit, but merely the expensive memory chips located inside. These are easily removed once the processor unit is opened and can be slipped into the thieves’ pocket unnoticed. Unfortunately, the cases are usually opened with a crowbar, or some similar implement, causing a lot of damage to the rest of the equipment.

In the past we have tried many different types of security system — electronic loop systems, steel straps, anchored steel cables, and movement detectors actually sited inside the units. Most had both advantages and disadvantages. Steel straps were not a success for us as we were unable to fasten them tight enough. Loop systems and anchored cables provided moderate security but still allowed the user to have a certain amount of movement of the computer.

The movement detectors are still in use and are something of a deterrent as they emit a 110-decibel whine whenever the equipment is moved. This should deter the sneak thief who wants a whole computer but may not bother the one with the crowbar. Sadly they work on the same principle as a car alarm, and how many of us hear those go off and decide either that it must be a false alarm or that someone else will investigate?

The security system that is currently regarded as being among the best by the North Eastern Universities Purchasing Group is a device called a PC CUFF. This is a robust steel unit that is bolted down and encases the processing unit, thus preventing both movement and access and deterring both our sneak thief and our chap with the crowbar. They are also recommended and approved by the insurance companies. A further testimonial must be that the University Security Manager has his own computer secured by one of these.
