I believe we are on the website, server, APP and other traffic *** is no stranger to it. Every corner of the world are played out every day network *** N multi-field, ******, which contains DDoS ***, CC *** and so on. We can look to a number of large enterprises *** suffered through the news media, but the most likely to be concerned DOS essentially many small businesses, such as electronic mall, payment site, gaming and other industries. *** Even without the danger of these companies face is the need to prevent it, to avoid being infringed.
They provided a method of prevention is to know what they mean difference. First, DoS denial of service representatives. *** can prevent users from accessing a computer, network or server. DOS usually flood the target Web server in order to trigger or make it crash. Unlike viruses, DOS does not need to run any specific program, the inherent nature of the primary use of the computer. *** who after obtaining the ability to execute DOS to access services and information, the server crashes often be restarted. But sources *** traffic more extensive, or it may be the source of many pages. Thus resulting in the system difficult to restore.
Then DDoS stands for distributed denial of service, is a malicious network *** behavioral targeting system for, mainly for network layer, transport layer, session layer and application layer *** *** exactly how this plays the role of it? ? Traffic congestion is typically utilize large network bandwidth *** who occupy the server's application layer processing resource pool of connections and tying up server after consumption of server processing performance results in the *** who can not access the service, which is called distributed denial of service.
So why should we be DDoS ***? Like other ******, there are many reasons can explain this. There may be to prove that he is a *** and to establish the credibility of the initiated; or to earn large sums of money through extortion ***; or is accompanied by vicious competition, so that other users *** experience a sense of deterioration, then give up the platform.
Finally, how to protect the network from DOS and DDOS against it? Ink security guard DDoS *** think the first step is to establish a high-performance processor infrastructure, increasing the height of the bandwidth; detection equipment installed real-time monitoring, when the request was found malicious traffic, through technical means to filter cleaning and then forwarded to the correct and effective flow of the source station; regular system scans killing, update patches; preference BGP routes. This can effectively alleviate the persecution of DDOS.
