A CDE Definition
See denial of service attack.
denial of service attack
An assault on a network that floods it with so many requests that regular traffic is either slowed or completely interrupted. Unlike a virus or worm, which can cause severe damage to databases, a denial of service attack interrupts network service for some period.
A distributed denial of service (DDOS) attack can employ hundreds or even thousands of computers that have been previously infected. The computers act as a network of "zombies" working together to send out bogus messages, thereby creating huge volumes of phony traffic.
In 2016, the Dyn DNS system was hammered by a DDOS attack that caused sporadic slowdowns of major sites such as Twitter, Netflix and The New York Times. The zombie traffic reached more than 100 gigabytes per second of bogus messages. See botnet, smurf attack, SYN flood attack, land attack, teardrop attack and Ping of Death.
