Their aim is to hack or damage a variety of many of the essential links some from the banks and some from the website of news and another main aim after this is that people can have a bulk of information with this. Which is potentially more dangerous and devastating? Distributed Denial-of-Service Attacks. Victims of a DDoS attack consist of both the end targeted system and all systems maliciously used and controlled by the hacker in the distributed attack. Im Fall einer durch eine Vielzahl von gezielten Anfragen verursachten, mutwilligen Dienstblockade spricht man von einer Denial-of-Service Attacke und, wenn die Anfragen von einer großen Zahl an Rechnern aus durchgeführt werden, von einer Distributed-Denial-of-Service attack (DDoS-Attacke, deutsch wörtlich verteilte-Verweigerung-des-Dienstes-Angriff).

A distributed denial-of-service (DDoS) attack occurs when multiple machines are operating together to attack one target. The Denial of Service attacks that we will be discussing today are called Distributed Denial of Service (DDoS), which result from a large number of systems maliciously attacking one target. In most respects it is similar to a DoS attack but the results are much, much different. Da beim DDoS-Angriff die Anfragen von einer Vielzahl von Quellen ausgehen, ist es nicht möglich, den Angreifer zu blockieren, ohne die Kommunikation mit dem N… They target a wide variety of important resources, from banks to news websites, and present a major challenge to making sure people can publish and access important information. dos (denial of service) - a type of attack that prevents any users - even legitimate ones - from using a system.
