Everyone should be familiar with DDoS attacks. Nowadays, network attacks are frequent. How to effectively protect against DDoS must be a key concern for many people. High-defense IP is a relatively common defense product. Many people choose to use high-defense IP to defend against network attacks without wanting to replace the server.
When a website suffers from a DDoS attack, the traffic carried may instantly exceed the range that the server can withstand, causing the cloud server to be shut down. At this time, there is a risk of attackers taking the opportunity to steal confidential data.
If a network attacker wants to conduct a DDoS attack on a target, he must know the ip address of the target server, and initiate a large number of service requests to the IP server, occupying a large amount of server resources, making it unable to respond to normal requests. At the same time, the bandwidth resources of the server where the IP is located will also be occupied by these large amounts of invalid data, causing information congestion.
Principles of protecting against DDoS attacks
According to the principle of DDoS attack, it is not difficult to understand that in order to defend against DDoS attacks, it must be carried out in two steps: one is to ensure the stability and reliability of the source site; the other is to filter malicious traffic.
Ensure the stability and reliability of the source station
Network attackers conduct DDoS attacks through IP, so users can configure high-defense IP to divert attack traffic to high-defense IP to ensure the stability and reliability of the source site. High-defense IP is a paid value-added service specially designed for Internet enterprise servers to effectively protect against DDoS attacks when normal services cannot be performed after a large traffic DDoS attack.
Filter malicious traffic
Usually high-defense servers are used to defend and manage IP. If the high-defense IP provided by the service provider has abnormal traffic, the hardware firewall in the high-defense computer room, traction system, etc. will intelligently identify the traffic and perform malicious traffic. Filtering to ensure that requests sent by the server from normal traffic can be processed normally.
The high defense IP protects the origin server through the proxy forwarding mode, and the business traffic directly accesses the IP, and then returns to the origin server. If a DDoS attack occurs, the protection system will filter and clean the attack traffic when it passes through the high-defense IP, and forward the clean business traffic back to the source to the source to the business server to ensure the possibility of the business in the DDoS attack scenario.
Anti-IP is a more convenient product to use and can be used immediately after purchase. It does not have desktop operations like servers, and it cannot log in remotely. There is only one control panel as the setting interface. When the source server is attacked and the enterprise does not want to transfer data or replace the server, a high-defense IP is a good choice. The DDoS protection effect is better, but the website acceleration ability is slightly weaker, and it supports hiding the origin site.
DDoS high defense IP advantage
One-click defense, multiple cleaning strategies and IP polling defense. You only need to modify the IP address to be protected to the address of the high defense IP to complete the access to the DDoS defense service. Open multiple sets of cleaning strategies, users can flexibly adjust cleaning strategies according to the attack situation, quickly respond to different types of DDoS attacks, and significantly reduce the harm of DDoS attacks. By polling multiple high defense IPs through load balancing, DDoS attack traffic is evenly distributed to multiple IP addresses, transforming large attacks into multiple small attacks, making defense easier.
DDoS high-defense IP services are suitable for DDoS scenarios such as financial, gaming, coal, e-commerce, government and other network attacks. In particular, services that require real-time user experience, such as real-time online games, online finance, and e-commerce online education, should be protected by high-defense IP.
