3.5.2.5 Anti-DoS
Denial-of-Service Attack (DoS attack) is a type of attack on a network that is designed to
bring the network to its knees by flooding it with useless traffic.
A denial-of-service attack (DoS attack) is an attempt to make a computer resource
unavailable to its intended users. One common method of attack involves saturating the
target machine with external communications requests, such that it cannot respond to
legitimate traffic, or responds so slowly as to be rendered effectively unavailable. Such
attacks usually lead to a server overload.
In general terms, DoS attacks are implemented by either forcing the targeted computer(s) to
reset, or consuming its resources so that it can no longer provide its intended service or
obstructing the communication media between the intended users and the victim so that they
can no longer communicate adequately.
Enable DoS Preventionto detect and prevent denial of service attacks through automatic rate
filtering or rules toprotect legitimate users during the DoS attacks.
