what is DDOS?Working And Different Types Of Denial Of Serive (DoS) Attack
A Denial of Service (Dos) attack targets a server or other network element in attempt to cripple or making it completely unavailable. It is unlike identity attacks, malicious code, phreaking and other basic attacks where the goal is to steal data or a resource.
The primary purpose of DoS attacks is to prevent legitimate users from accessing a certain resource. A DoS attacks can be initiated to consume limited or all resources, modify or destroy data or configuration information or to physically destroy or disturb network components.
When a Denial of Service attack is launched, it floods the network resources with requests and overwhelms it and keeps ignoring the server’s response because the attacking computer is programmed to ignore all server’s responses. The server awaits a response, which it never gets and the line remains busy. This result in increased traffic, making the system unable to handle this intensive activity, thus the server then becomes unavailable for other requests that come in. A Denial of Service attack launcher makes sure that the attack makes the server to run out of resources and performance is decreased or lost.
