The United States DP High-protection room, high anti-high anti-server, can effectively protect against DDoS and CC attacks. The 21st century is the era of computer network, with the rapid development of the network era, network attacks are also gradually raging, network security issues become the majority of the webmaster's heart, have a anti-attack
Next we have a detailed understanding of the DDoS attack protection capability and its settings:
The user can turn on/off the DDoS firewall function by clicking the "turned on"/"Closed" button at the top right of the action interface. It is recommended that users install the server security dog and immedia

Introduction to DDoS
The most common attack is a distributed denial of service (DDoS) attack on a Web site. In a typical DDoS attack, an attacker consumes service resources by sending a large amount of data to the server. To prevent access to other users.

DDoS attack wave affects Enterprise Development
DDoS attacks cannot be ignored by enterprises nowadays. In particular, for some large enterprises, their main businesses are accumulated in servers. If the servers are attacked, the loss of important information or con

the server may have to trace a record from tens of thousands of records to handle the request, a process that is expensive for resources, Common database servers rarely support hundreds of of simultaneous query execution, which is easy for the client, so the attacker can simply submit a query to the host server via proxy proxies, consuming server resources in mi
commands, which is easy for clients. Therefore, attackers only need to submit a large number of query commands to the host server through the proxy, it takes only a few minutes to consume server resources and cause a denial of service. A common phenomenon is that the website is slow, such as snail ing, ASP program failure, PHP database connection failure, and the CPU usage of the database master program is
