LinuxSecurity: "Denial-of-service (DoS) and distributed denial-of-service (DDoS) attacks have been around for years, but with reports that 4,000 DoS attacks are
launched each week, it's clear the problem isn't close to being resolved. In fact, in a recent poll of Information Security readers, 90 percent said they
remained either "very concerned" or "somewhat concerned" about DoS or DDoS (see Reader Poll)."
