DDoS attacks against DNS providers are generally more challenging to accomplish, given the redundant nature of the services, which suggests that this attack came with significant firepower. DNS attacks, when successful are however more damaging as they impact any Internet properties relying on that particular DNS provider.
A DoS or DDoS aims to exhaust the resources at the disposal of a server, most often the ones linked to the network. However, it is also possible to saturate the disk, the RAM, or the targeted machines’ processors.
We separate here the applicative DDoS from the network DDoS, since the method are different, as well as the way to block them. However, when you hear about a DDoS, this term refers to the network DDoS.
In today's world, DNS is a fundamental part of critical infrastructure. DNS provides the translation between human friendly domain names and machine readable IP addresses. In short, without DNS services, users are unable to reach websites, even though the sites themselves may be running just fine. Given the amount of commerce done over the Internet today, it is not surprising that the US Department of Homeland Security is already investigating the attack.
