DDoS (Distributed Denial of Service) is a more and more common attack. It uses a large number of servers/computers to submit the same request to block the bandwidth, so that other normal traffic cannot enter. For example, if your Hong Kong server provider has 1Gbps upstream bandwidth, when DDoS attackers use 4Gbps, 10Gbps or more traffic to occupy your connection, then your bandwidth will be completely saturated, and all normal traffic will not be able to pass through the connection, thus Take your business offline.

1. DDoS Attack Principle and Severity

From a technical point of view, DDoS may involve the abuse of the underlying communication protocol (TCP SYN_ACK / UDP broadcast, etc.), the principles are similar: saturate your Hong Kong server system / router / bandwidth channel, unable to handle more and more requests, Eventually others cannot connect.

DDoS attacks are more common than ever, and the scale of traffic attacks is getting bigger and bigger. They are not limited to well-known sites, including competitors, and even those potential startups. Therefore, it is very important to enable proper DDoS protection for your Hong Kong server in the era of exploding internet economy.

2. How does the Anti-DDoS server in Hong Kong realize DDoS protection

Through the DDoS intelligent monitoring and processing system, Hong Kong Anti-Defense Server can monitor the import and export traffic in real time, and accurately identify bad or malicious traffic through the difference between standardized normal traffic and abnormal traffic. After detecting malicious traffic, it will automatically switch to the high-defense dedicated line in seconds. Through the traffic cleaning rules, the data packets will be intercepted and blocked before they reach your server, and normal traffic data packets will be allowed to reach your server. Therefore, it is allowed Your website can continue to operate even in the face of DDoS attacks. At the same time, through the high-defense dedicated line, a large amount of malicious web traffic is directed to the North American network, and the massive North American network is used to clean, dilute and mitigate the attack, and finally achieve a T-level or above DDoS large-traffic attack defense.
