Information security has always been an arms race between IT and hackers. The bad guys launch a threat, IT counters with safeguards and the bad guys develop a new threat that gets around the safeguards.
Currently the front line has shifted from layer 4 to layer 7 attacks. While most traditional safeguards can handle layer 4 threats like SYN Flood DoS attacks, layer 7 threats, such as SlowLoris, are trickier. They get by layer 4 defenses because they look like legitimate traffic.
In effect, hackers have raised the ante. It is now IT’s turn to respond.

Application Delivery Controllers (ADCs, sometimes called next-generation load balancers) are, in many ways, perfectly suited to the task. They understand the context of the traffic they manage at all levels (including layer 7). They have the compute power required plus deep packet inspection to react to advanced, persistent and distributed threats. And they have the ability to react and mitigate attacks.
