What is the rejection of the attack?

Attack Denial of Service (DOS) is an attempt to create a web or other Internet source that users unavailable. Attacks from the rejection of services can be very expensive because businesses will lose money and customers are not available every hour; They are generally illegal and also violate the right policy of the Board of Internet architecture. The traditional attack of the rejection of the service is carried out by flooding the target server with fictitious requirements, overloading and preventing it from handling legitimate operation; Other types of attacks include the postponement of a network connection, collapse of the server or closing the service for one particular person or group.

Denial of Service Attacks based on overload of traffic is usually very easy to start; The primary requirement is a large amount of bandwidth. If the target server is flooded with more data requirements than the bandwidth, they will not be able to go through the valid requirements and the server owner can also be charged for Excalesvire Susease. Variations include a distrust attackIbuted Denial of Service (DDOS), which includes the kidnapping of a large computer network, and then all programming to flood the same goal. This can be done using viruses, worms or other malware that can be programmed to attack and reduce a specific site.

various network tricks can also be used to initiate an attack by rejection of the service, such as sending an excess packet in several pieces; The target server will try to put them back together and can collapse with an error message. If the server operating system has a slight security hole, hackers can allow the server data to be downloaded before their disruption, which could endanger sensitive information such as credit card and social security numbers. The "attack" of the rejection of the service may even be unintentional; Website such as Slashdot, Digg and Reddit often Deliver huge amounts of traffic on small, relatively unknown websites that can't handle ally requirements and turn off. This was originally known as "Slashdotted", although other websites often cause this problem.
