Nicholas Thompson, editor-in-chief of WIRED, discusses technology industry news today:

What is a DDoS attack and how can they be prevented?

That's a digital denial of service attack. Somebody uses malware to infect a bunch of computers or Internet of Things devices and sends lots of traffic at a server trying to knock the server offline. What can you do if you own the server? Buy more space, become part of a large operation like AWS that can offer you expanded space during the time of an attack, and build good filtering and blocking software.
