Network DoS Attacks Overview

A denial-of-service (DoS) attack directed against one or more network resources floods the target with an overwhelming number of SYN, ICMP, or UDP packets or with an overwhelming number of SYN fragments.

Depending on the attackers' purpose and the extent and success of previous intelligence gathering efforts, the attackers might single out a specific host, such as a device or server or they might aim at random hosts across the targeted network. Either approach has the potential of upsetting service to a single host or to the entire network, depending on how critical the role of the victim is to the rest of the network.
