High -security high -defense server refers to a server that can resist DDOS/CC attacks. DDOS is an attack method. When the target is attacked by DDOS, the low -target system resources will be exhausted and cannot respond to normal service requests. The essence of the DDOS protection system is a smart system based on resource competition and rules. For the current popular DDOS/CC traffic attacks, technologies such as Yunqingli Cluster and Database monitoring and traction systems can effectively weaken DDOS high protection services.

　　At present, there are many "senior defense servers" and "high -defense hosts" in the market. When users choose a high -end defense server, they can consider safety, cost benefits and availability. Among them, security is the core. If the high -level defense server cannot solve external attacks, no matter how cheap it is, it cannot choose it. Let us understand the decisive factor of high -level defense server security:

　　1. Server and bandwidth resources. The peak services of mainstream cloud service providers can resist common types of attacks, such as SYN floods of the application layer, ACK flood, ICMP flood, UDP flood, DNS flood, HTTP flood, CC attack, etc. However, the ultimate success of protection depends on the bandwidth that the manufacturer can protect. JTTI DDOS high protection services provide a 1T large protection bandwidth, and a single IP protection capacity can reach hundreds of G, which means that the large bandwidth can calmly cope with the large traffic attack.

　　2. Flow analysis ability. Only by analyzing massive data and modeling legal users can we accurately clear DDOS traffic. With the help of DDOS high protection services, users can configure high protection IPs to transfer attack traffic to high protection IP and resist oversized DDOS attacks.
