Protect your network from rogue users

IT departments spend a great deal of time, effort and money to protect against external threats ? those that enter the network via the Internet or remote access ? but sometimes forget the harm that can be done by an authorized user who decides to ?go rogue? (circumvent network security policies for his/her own purposes).

Just as retail stores often find that more losses come from employee thefts than from outside shoplifters, some companies might be surprised to learn that they are at least just as much at risk from their internal users as from Internet hackers. Sometimes it?s inadvertent; non-tech savvy users may inadvertently visit Web sites that run malicious code or innocently download programs they think will be useful on the job that contain spyware or click on email attachments that contain viruses or attach their laptops (that have, unbeknownst to them, picked up malicious software from unprotected home or hotel Internet connections) to the company network. They usually don?t realize their actions violate policy or best security practices.

The rogue user, though, knows that he/she is violating network policies and often has some advanced technical knowledge. That doesn?t mean the intent is to bring down the network or introduce an attack. Usually the rogue user just wants to defeat your security mechanisms because they inconvenience him ? but doing so can have unintended consequences that can be devastating to your network.
