AT&T: Service restored after cyberattack

19 Aug

AT&T Inc. said some business customers temporarily lost Internet access because its network was targeted by unknown attackers on Wednesday.

Company spokesman Mark Siegel said that domain namesystem, or DNS, servers that direct traffic for AT&T customers were targeted at two locations by a distributed denial of service attack. In such attacks perpetrators target a server with a lot of requests at the same time, making it unavailable to users.

The issue has now been resolved, he said.   –  Chicago Tribune

    I am not surprised to hear about DDOS on DNS. DNS is often the weak link. What is there defending DNS?

      An identity layer would defend DNS. It would certainly differentiate between strange and acceptable connection requests.
