South Korea builds digital 'bunkers' against DDoS attacks

The country has forged a network of digital 'bunkers' to protect against a repeat of the distributed denial-of-service attacks that hit its networks last year

South Korea has installed digital 'bunkers' to prevent a repeat of the massive distributed denial-of-service attacks that crippled parts of the country last year.

The nation was floored after huge streams of junk internet data poured across South Korea's networks, targeting the infrastructure of government and businesses in what is known as a distributed-denial-of-service (DDoS) attack. "We were caught off guard," Jinhyun Cho of the Korea Computer Emergency Response Team (KrCert) told ZDNet UK's sister site ZDNet Australia. "It was on the mouths of everyone; the whole country knows what a DDoS attack is."

The attacks forced telcos to co-operate with KrCert to forge 'DDoS bunkers' to protect the nation's small-to-medium enterprises from attack. Simply put, a bunker is a new IP address served to a business that is under persistent DDoS attack but lacks the funds or resources to protect itself.
