The types and strengths of DDOS attacks are different, so there is no way to completely protect the server from all DDOS attacks. Take a variety of protection measures to improve the security of the server.

　　Flow analysis and monitoring: Use traffic analysis and monitoring tools, such as network traffic analyzer or intrusion detection system (IDS) to discover abnormal traffic and attack behavior in time. These tools can help you understand the traffic mode on the server, which is convenient for detecting and responding to DDOS attacks.

　　High bandwidth and load balancing: Make sure your server has sufficient bandwidth to deal with large -scale traffic shocks. Use load balancing technology to disperse flow to multiple servers to reduce the pressure of a single server. In this way, even if a server is attacked, other servers can continue to provide services.

　　DDOS firewall: Configure the DDOS firewall to filter and prevent malicious traffic. These firewalls can be screened according to the characteristics of traffic, IP address, or other standards to distinguish normal traffic and attack traffic, and intercept the attack traffic.

　　Enhance network infrastructure: Make sure your network infrastructure can withstand and cope with large -scale DDOS attacks. Use powerful network equipment and protection mechanisms, such as invasion defense system (IPS) and reflection amplification attack protection to reduce the impact of attacks.

　　CDN (content distribution network): Use CDN to distribute and cache your server content. CDN has a distributed node, which can scattered traffic to different servers, reduce pressure on single servers, and provide better performance and availability.

　　Increase bandwidth elasticity: Increase the elasticity of bandwidth when expected to face DDOS attacks. This can ensure that the bandwidth capacity can be quickly expanded quickly by cooperating with your service provider.

　　Cloud service provider: consider deploying the server on the platform of a reliable cloud service provider. Cloud service providers usually have powerful network infrastructure and DDOS protection mechanisms to better cope with DDOS attacks.

　　Emergency response plan: Formulate a comprehensive emergency response plan to be able to respond quickly when suffering from DDOS attacks. This includes allocating responsibilities, establishing communication channels, backup data, and quickly switching to spare servers when attacking.
