The Need for Security

The New Reality In the good old days, network threats were fewer and far between. A teenager sitting in his room might try to discover your backdoor modems using a war dialer inspired by the movie of the same name.

However, attacks from crackers, hackers, phreakers, and phrackers are no longer benign. War has been declared. Make no mistake; there is a war going on. Your organization’s infrastructure is at risk. As a network and security professional, you are on the front line in defending your enterprise.
