Botnet
Ataque de denegación de servicio que se realiza
utilizando múltiples puntos de ataque simultáneamente.
Ataque DoS en el que participan gran cantidad de
máquinas atacantes. [CCN-STIC-612:2006]
A technique that employs two
or more computers, such as the bots of a botnet, to achieve a denial of service
from a single or multiple targets.
The Tallinn Manual, 2013
Denial of Service technique
that uses numerous hosts to perform the attack.
[CNSSI_4009:2010]
A DoS technique that uses
numerous hosts to perform the attack.
[NIST-SP800-61:2004]
When more than one system is
used to attack resources of a single server to create a denial of service
attack.
A DoS attack launched
against a site from multiple sources.
Generally the attacker places client software on a number of
unsuspecting remote computers, then later uses these computers to launch an
attack. A DDoS attack is more effective
than a simple DoS attack and is more difficult to prevent.

On the Internet, a
distributed denial-of-service (DDoS) attack is one in which a multitude of
compromised systems attack a single target, thereby causing denial of service
for users of the targeted system. The flood of incoming messages to the target
system essentially forces it to shut down, thereby denying service to the
system to legitimate users.

Attack is a means for
attackers, using multiple attack points or multiple attackers, to attempt to
shut down a given website or online activity with massive and overwhelming
numbers of requests to the server that hosts the site or activity; this attack
method is often used by cyber criminals for online extortion.
Denial of Service de
type distribué, c'est-à-dire en provenance de multiples sources permettant
ainsi d'accroître l'efficacité de l'attaque et les dégâts causés à la cible.

Le déni de service
distribué (DDOS, Distributed Denial of Service) est une forme particulière de
déni de service, simple et efficace, particulièrement répandue.
Un déni de service
distribué consiste en l'utilisation synchronisée de plusieurs machines, en
général des victimes de chevaux de Troie qui, a leur insu, déclenchent une
attaque par déni de service sur une cible particulière.
Les outils
classiquement utilisés pour générer des dénis de service distribués sont:
·
TFN/TFN2K
(Tribe Flood Network) permettant de générer des attaques de type ICMP echo, SYN
flooding et SMURF attack.
·
TrinOO
génère des attaques distribuées de type UDP flooding.
Ce type d'attaque a notamment
été utilisé par le hacker canadien MafiaBoy contre les sites de CNN, Yahoo...
