With every change in technology comes an opportunity to violate systems and newer intrusions are getting to be more creative and effective. In one case in 1993, a long distance telephone company card holder compromised his card and 600 unauthorised international calls were placed on that card before network specialists detected the problem and disconnected the violators. All these happened in less than two minutes. Law enforcers and security managers have to be faster and smarter. They cannot continue the traditional approach of ‘security through obscurity, which is the keeping of vulnerable data security. There is need to embrace technology and device security policies that not only dissuade the violator from breaking into the system but also catch the violator. It is such technologies and policies that are the subject for this topic.
