What is DDoS?

How multiple machines can be used to crash a targeted system.

By Ellie Burns

DDoS stands for distributed denial-of-service and is a type of cyber attack in which multiple systems flood the bandwidth or resources of a targeted system.

The idea behind a DDoS attack is to overwhelm systems, usually one of more web servers, in order to crash or suspend services of a host connected to the internet. It is usually likened to a group of people all trying to get through a shop door all at once, with the crowd obstructing the entry of legitimate visitors and thus, disrupting business.

The main advantage of DDoS over DoS, or denial-of-service, is that multiple machines can generate more traffic than one, making it harder for such an attack to be stopped.
