Denial of Service

aliases:

DoS
DDoS

A type of web server threat that overwhelms the target server with loads of data it cannot handle, causing it to shut down.

Denial of Service attacks can target a network, specific apps or services, or even the underlying systems used to monitor and control industrial operations. With modern technology, one system is now enough to perform a DoS attack. When attackers use multiple systems to bombard a target, it's called a Distributed DoS attack, or DDoS.

DoS Attack Methods

Method	Description
App Layer	Targets a specific application or service being used on the web server.
Protocol	Targets a protocol to overload network devices, like a firewall. Most common is a TCP/IP SYN flood attack.
Amplification	Consumes the bandwidth between the target and the Internet, effectively cutting it off from all other traffic. Most common is a DNS amplification attack.
