Vancouver, BC - The network engineer from the www.clear-ddos.com has given us more information about the DDoS atack. The principle of the DDoS atack is by a large number of legitimate requests to take up a lot of network resources. At last, you network would be paralysis by the large amount of the legitimate requests. The Clear-ddos.com has told us that such DDOS atacks can be divided into the following categories.1. Use the Overload of the network to interfere or even block the normal network communications.2. Submit large number of requests to the server to make the server overload.3. Blocking a user to access the server.4. Blocking the communication of servicer with a specific system or personal.The first type of DDOS atack the Clear-ddos.com want to introduce with you is the SYN flood. The SYN flood is one of the DDOS atacks that a hacker send false packet to the server to trick the server. Frankly speaking, it is mean that the original IP address in the packet would be set to the value which does not exist or not legitimate.
Once the server receives the package, it will return to accept the request packet. But in fact this package will never return to the source computer. This approach would make the server open the listening port to continue to wait the return from the source computer. This will waste huge system resources.
That is why many companies need the [url=http://www.clear-ddos.com/]ddos protection[/url] . The second is the LAND atack. This atack way is similar to the atack way which name is SYN floods. But the original and destination addresses in the atack package of LAND Atack are the IP of the atacked object. That kind of atack would cause the atacked machine infinite loop and eventually run out of resources and crsh. It is the dirty atack type. The ICMP flood is that the atacker sends broadcast messages to the router to take up the system resources.
The last atacking method the Clear-ddos.com wants to tell you is the Application level floods. This kind of atack type has big difference with the atack way we have told you before. The Application level floods are mainly aimed at the application software layer that is higher than the OSI. Application level floods are also aim at consuming a lot of system resources. It use the IIS network services to call for the unrestrained application of resources which would do harm to the persecution of normal network services.
In a word, we could only say that the [url=http://www.clear-ddos.com/]ddos protection service[/url] and anti DDOS server such as the services which provided by Clear-ddos.com are necessary in our daily life.
