The difference between advanced anti DDoS server and advanced anti DDoS IP

　　 Frequent security threats to servers may cause serious damage to online business . Attackers use various tools and technologies to carry out malicious activities in the network , All these will affect the income of the enterprise . therefore , It is very important to provide strict security for your network system . At present, advanced anti DDoS servers and advanced anti DDoS IP In defense DDoS It is widely used in . This article will start from the definition 、 Make a distinction between principle and defense , So that you can make better choices .

　　 Conceptually ：

　　 Simply put, literally , Advanced defense server ( Independent single hard defense 50G The servers above ) And advanced defense IP( these IP It can defend against common on the network DDOS The attack ) One is the server , One is IP, Two different concepts .

　　 From the way of use ：

　　 The use of advanced anti DDoS server involves migrating website data , Change servers . imagine ： If your website was in an ordinary computer room , There are no security measures , When attacked , You cannot migrate to the advanced anti DDoS server immediately , Naturally, there is no counterattack .

　　 And high defense IP It can be deployed on the original server DDoS Defense Services , At this point, the former has more advantages . High prevention IP Deployment process of , Generally speaking , After domain name resolution / configure port -- Set forwarding rules ( Website type users can choose to access HTTP/HTTPS Such agreement , Protection support configuration for non website users TCP/UDP Such agreement )-- Filter malicious traffic ( All traffic accessing the source station needs to go through advanced anti DDoS IP), The protective effect can be achieved .

　　 In terms of working principle ：

　　 Advanced anti DDoS server is a firewall device with defense performance directly configured on the hardware of the server , Before the traffic is connected to the server, it will be identified through the firewall , Abnormal traffic will be blocked outside the firewall and cannot be directly connected to the server host , So that your team can stop the attack , Normal traffic access is unaffected . Of course, in addition to hard defense , Advanced anti DDoS servers can also be equipped with soft anti DDoS ( Software protection )、 The combination of soft and hard defense mode .

　　 Access to advanced anti DDoS IP, All traffic accessing the source station needs to go through advanced anti DDoS IP, With its traffic cleaning technology, it will clean and filter malicious traffic , Return the normal traffic to the origin IP, To protect the source station from being discovered by attackers .

　　 In terms of defense ：

　　 The conventional way for advanced anti DDoS servers to achieve defense ：1. Scan existing network master nodes regularly 2. Configure the firewall on the backbone node 3. Use enough resources to consume hacker attacks 4. Make full use of network equipment to protect network resources 5. Filtering unnecessary services and ports 6. Check the source of the visitor . It can prevent common DDOS、UDP、SYN、HTTP GET Wait for traffic attacks , Provide customers with safety maintenance .

　　 High prevention IP The conventional way to achieve defense ：1. Find the attack —— Filtering attacks —— Monitoring data .DDoS The security protection is deployed on the original server , Hide the user business source IP, It can resist various types of network-based layer 、 Transport layer and application layer DDoS A malicious attack .( Such as SYN Flood、ACK Flood、ICMP Flood、UDP Flood、NTP Flood 、SSDP Flood、DNS Flood、HTTP Flood、CC attack .)2. Have elastic defense , When the attack traffic exceeds the protection peak , Elastic protection can be added , Get higher DDoS Protection capability .
