DDoS Attacks: Page 3
You should also keep yourself current on the latest DDoS developments. The best site for this is the University of Washington hosted: Distributed Denial of Service (DDoS) Attacks/tools.
Essentially, these corporate approaches consist of intense real-time monitoring of your network looking for telltale signs of incoming DDoS attacks. These give you a chance to harden your network or even switch to another ISP provider in an attempt to dodge a DDoS attack. For example, Riverhead actually diverts DDoS attacks to its own servers and filters out the good traffic, which it then passes along to your site.
And, let's face it, today almost all businesses need to be on the net 24 by 7. With DDoS attacks on the rise according to CERT, you'd be wise to at least familiarize yourself with DDoS prevention services. After all, it's not only your network in danger, it's your business.
