Denial of service

A Denial Of Service (DOS) attack is an attack designed to prevent some information resource from being used. This can include jamming up network pipes with traffic that slows down access, attacks that can shut down a device (computer, router, gateway…), attacks that change configuration parameters and many more. While the ideas are unlimited, most conventional DOS attacks involved some form of flooding a device with traffic. Denial of service attacks can seriously disrupt an organization. Responses to DOS attacks often include tracking down the source of the disrupting traffic and finding some way to quench it.

Distributed DOS attacks (DDOS) are DOS attacks that are sourced from a distributed array of points, making it much harder and sometimes impossible to pinpoint the source of the attack and stop the disruptive traffic from reaching the targets. They can be very difficult to supress. Many of them use spoofing techniques and timing patterns that turn the sources on and off in bursts to make it harder to locate them.

DOS and even DDOS attacks launched from INSIDE an organizational perimeter would be devastating.
