From a summary article by Fred Donovan in FierceITSecurity.
Attacks against the domain name system are on the rise, with a 200 percent rise in DNS attacks in the last year, according to data from Prolexic.
A few months ago, there was a rash of DNS hijacking attacks against customers of Network Solutions by a pro-Palestinian group, which redirected traffic from the customers’ websites to its website.
In addition, attackers are able to compromise the DNS to launch distributed denial of service attacks that flood websites with malicious traffic.
“DDoS challenges have spiked for enterprises in 2013 … An increase of higher-volume and application-based DDoS attacks on corporate networks will force Chief Information Security Officers (CISOs) and security teams to find new, proactive solutions for reducing downtime,” observes Gartner analyst Lawrence Orans.
