ABSTRACT
Prevention is the key when it comes to network security. Identifying and stopping intrusion-in all its forms-is what security is all about. But identifying a potential intrusion is not always obvious, or likely. The usual security suspects-Soviet spies, CIA agents, and industrial espionage-make great headlines, but they don't pose real risks to the average company. However, just because you're not building the next secret weapon doesn't mean that you're not at risk from security breaches. Far more often, security risks come from acts committed out of human error, greed, malcontent, or machine error.
