Massive DoS Attacks Against ISPs On The Rise
Large scale denial-of-service attacks, growing in size and increasing in frequency, are the biggest threats to Internet service providers, a security company said. ISPs are spending more to defend against massive denial-of-service (DoS) attacks than they are protecting themselves against highly-publicized worm attacks, Lexington, Mass.-based Arbor Networks reported in its annual survey of major providers.
Providers, said Arbor, regularly report attacks beyond the capacity of core backbone sections of the Internet in the 10-20Gbps range.
The bulk of these DoS attacks originate with botnets, collections of compromised computers that criminals have acquired by infecting them with Trojan horses through other means, such as e-mail, spyware, or malicious Web sites.
