Good read on new DDoS methods and response from Carnegie Mellon.
“We have recently seen more sophisticated attacks, such as the recent Dyn attack. As IEEE Spectrum recently reported, “Attacking a DNS or a content delivery provider such as Dyn or Akamai in this manner gives hackers the ability to interrupt many more companies than they could by directly attacking corporate servers, because several companies shared Dyn’s network.”
“Generally speaking, organizations should start planning for DDoS attacks in advance. It is much harder to respond after an attack is already under way. While DDoS attacks can’t be prevented, steps can be taken to make it harder for an attacker to render a network unresponsive.”
