DDoS rife at ISP's

Companies should devote more resources to countering old-fashioned DDoS attacks when investing in security, a survey of global ISPs has argued.The figures from Arbor Networks in its Worldwide ISP Security Report came from questionnaires sent to 36 large ISPs in the US, Europe and Asia.

Over 90 percent of ISPs surveyed cited simple "brute force" TCP SYN and UDP datagram DDoS floods from zombie PC networks as their biggest day-to-day hassle, a finding which should apply equally to their corporate clients. This puts DDoS ahead of more recent attack types such as fast-spreading worms and DNS poisoning, which were ranked second and third respectively, in terms of prevalence.

Surprisingly, given the prevalence of this type of attack in recent years, only 29 percent of ISPs offered services to counter and trace DDoS in an automated way at the ISP level. The majority only discovered such events when a customer contacted them for help.
