[CS] Distribuované odepření služby (DDoS, Distributed Denial of Service): Kybernetický útok zabraňující oprávněným uživatelům v přístupu k on-line službě nebo zdroji tím, že je zahlcuje větším množstvím požadavků, než mohou zvládnout.

National Definitions
Australia
Denial of service: Deliberate compromise of the availability of IT systems. [2]
Denial-of-Service (DoS): An attack that is used to stop an online system (such as a website) from being available to legitimate users. [3]
These attacks often flood targeted systems with requests until they are unable to respond.
Bermuda
Distributed Denial of Service (DDoS): the intentional paralyzing of a computer network by flooding it with data sent simultaneously from many individual computers. [4]
Burkina-Faso
Déni de service (Deny of service ou Denial of Service ou DoS): Ensemble de techniques d’attaques, venant d’une même source, ayant pour but d’interrompre la fonction d’un serveur et de le rendre indisponible. [5]
La méthode la plus classique consiste à faire crouler le serveur sous une masse de requêtes généralement mal formées pour entraîner une réponse anormale et paralysante. Une attaque distribuée venant de plusieurs sources est appelée DDoS.
DoS, DDoS, Sabotage: By this kind of an attack a system is bombarded with so many packets that the operations are delayed or the system crashes. [5]
Examples of a remote DoS are SYS-a. PING-flooding or E-mail bombing (DDoS: TFN, Trinity, etc.) However, the availability also can be affected by local actions (destruction, disruption of power supply, etc.).
Cameroon (Cameroun)
Déni de service distribué : attaque simultanée des ressources du système d’information ou du réseau de communications électroniques, afin de les saturer et amplifier les effets d’entrave. [6]
Canada
Denial of Service attack: Any activity that makes a service unavailable for use by legitimate users, or that delays system operations and functions.
Distributed Denial-of-Service attack: An attack in which multiple compromised systems are used to attack a single target. The flood of incoming messages to the target system forces it to shut down and denies service to legitimate users. [7]
Attaque par déni de service: L’attaque par déni de service (DoS pour Denial of Service) consiste en une activité visant à rendre un service inutilisable ou à ralentir l’exploitation et les fonctions d’un système donné.
Attaque par déni de service distribué: Attaque par laquelle une multitude de systèmes compromis visent une même cible. Le flux de messages envoyés est tel qu’il provoque une panne du système ciblé et l’interruption des services offerts aux utilisateurs légitimes. [8]

Distributed Denial of Service (DDoS): A cyber-attack where the perpetrator seeks to make a machine or network resource unavailable to its intended users by temporarily or indefinitely disrupting services of a host connected to the Internet; this sort of attack is typically accomplished by flooding the targeted machine or resource with superfluous requests in an attempt to overload systems and prevent some or all legitimate requests from being fulfilled. [10]
France
Déni de service (DoS): attaque informatique ayant pour but de rendre indisponible un service en submergent ses ressources informatiques de traffic inutile. Lorsque l'attaque est conduite à l'aide de plusieurs source de traffic malveillant, on parle de déni de service distribué (DDoS). [11]

DDoS - (от англ. Distributed Denial-of-Service) – распределенная атака типа отказ в обслуживании, которая являет собой одну из самых распространенных и опасных сетевых атак. В результате атаки нарушается или полностью блокируется обслуживание законных пользователей, сетей, систем и иных ресурсов.
DDoS - distributed denial-of-service attack is an attempt to make a machine or network resource unavailable to its intended users. A DoS attack generally consists of efforts to temporarily or indefinitely interrupt or suspend services of a host connected to the Internet.
