What users get isn’t necessarily what they want. The first a user may see of a new information system is at the testing or training stage. At this point, it will be seen whether the system as delivered by the IS/IT professionals is what the user actually needs. An appropriate analogy here is the purchase of a house or car simply on the basis of discussions with an estate agent or a garage, rather than by actually visiting the house or driving the car. It is unlikely that something purchased in this way will result in a satisfied customer and there is no reason to suppose that information systems developed in a similar way will be any more successful.

Physical theft, as the term implies, involves the theft of hardware and software. Data theft normally involves making copies of important files without causing any harm to the originals. However, if the original files are destroyed or damaged, then the value of the copied data is automatically increased. Service organisations are particularly vulnerable to data theft since their activities tend to rely heavily upon access to corporate databases. Imagine a competitor gaining access to a customer list belonging to a sales organisation.

The most common method of detection used by these programs involves scanning for the signatures of particular viruses. It is often possible to locate a virus by simply searching every file on an infected disk for these identifying characteristics. However, since new viruses are discovered quite frequently, the list of signatures contained within a detection program quickly becomes dated. For this reason, most software developers insist that regular program updates are essential. However, the introduction of new kinds of viruses, such as polymorphic and stealth viruses, mean that signature checking alone can no longer be regarded as a completely secure method of detection.
