Dos attacks pose a major threat to Internet security

Since the advent of the Internet, the DoS attack accompanied with the development of the Internet, and has been developing and upgrading. It is worth mentioning that to find a DoS tool is not difficult, the hacker social network community has a tradition of sharing hacker software, and will be together to exchange the experience of attack, can easily get these tools from the Internet, like the above mentioned DoS Attack Software is a publicly available software that can be found anywhere on the web.

so any Internet user can pose a potential threat to cyber security. DoS attacks pose a major threat to the rapid development of Internet security. In some ways, however,DoS attacks never go away and there is no technically fundamental solution.

from the various methods of cyber attacks and the resulting destruction, DDOS is a simple but effective way to attack. Attacks can be broadly categorized into the following three types: Flood attacks, protocol-depleted attacks, and application-level attacks. It is designed to make it impossible for users to access the site's services and disrupt normal operation, which in the end will invalidate some of the site's Internet connections and network systems.

In the process of defending or mitigating the attack, the most important part is to discover the attack, distinguish the request of fake fake address, malicious traffic, the second step is to use the surgical method to filter the false address request and malicious traffic, so that normal traffic can access the website or the server.

Most Web servers have limited export resources, and if you encounter a malicious attack with very large traffic, The root problem of network traffic congestion cannot be solved by processing only on the Web server side. In this case, the service provider is required to clean the malicious attack traffic in either the metropolitan area Network or the backbone's cleaning center. Last year Arbor, through its global ATLAS Threat Analysis platform, monitored malicious attacks with up to 42G of traffic, often in the form of cross -border and cross-carrier networks, This requires operators and service providers to deploy detection and cleaning equipment at the appropriate location in the network to protect against and mitigate attacks, while the devices in these cleaning centers can provide protection for such things as DNS servers,IDC, and so on. In addition, operators can provide such manageable security services to website operators and other business users.

currently Arbor can provide a single cleaning capacity of up to 40Gbps cleaning equipment, more than one cleaning equipment can form a powerful cleaning center.

Finally, security guard remind the user: for the network attack, You need to be proactive, and when you encounter an attack, you can respond calmly. Prepare for the worst. The machine may stop running, the motivated user may do something wrong, and the malicious motives of the user may do bad things and succeed in defeating you. But it's important to understand that this is not a complete disaster when these things happen.
