Every organization has to be connected to the Internet if it is to compete successfully in the business world of today. There must be no doubt whatsoever that this gives organizations of every type significant challenges as the virus writers and hackers of yesterday are forever finding new methods of mounting very effective Internet-borne attacks. The threat from outside the organization is only part of the problem. Information assets are also under threat from within and some say as much as 75% of the problem is as a direct result of attacks mounted by so-called trusted employees.
