Powerful services like WildFire and FlowScape can help you defend against a new generation of persistent network attacks.
The original network intruders were often misfit geeks operating from boredom or a need for thrills. As businesses went online, a new kind of intruder arose – a thief, poking around for credit card numbers or a chance to add another spam slave to the botnet.
This new breed of intruder brings a sophistication that takes the threat to the level of cyber attack. Well-funded and highly skilled criminal organizations can stake out a network for months – sometimes years, keeping constant watch and trying every trick they know until they find a way to slip past security.
