One of the most prevalent types of attempts at intrusions we see when monitoring our clients' networks is a Distributed Denial of Service (DDoS) attack. Can you explain what a DDoS is and what you would recommend to clients to prevent it?

"DDoS is an attack by someone attempting to compromise your network by flooding it with a large number of requests. Many networks are unable to handle this and respond by denying service to all users, even legitimate ones. It is called a 'Distributed' attack since the flood of requests can come from many different sources. The best way to defend against a DDoS attack is to analyze and filter network traffic using 'scrubbing centers.' These are servers on the network dedicated to analyzing network traffic and removing malicious requests. Our company offers this service as part of your network security package."
