DDOS is the abbreviation of distributed denial of service. High defense server provides defense services against DDOS attacks.

　　DDOS attack:

　　DDOS attack is a network attack. Its goal is to send a large amount of requests or malicious traffic to the target system to exceed the system processing capacity, resulting in unavailable services. Attackers usually use a large number of infected computers distributed in different geographical locations to form a huge network by collaborative work, called "zombie network" or "zombie army", and use this network to launch attacks.

　　High defense server:

　　High defense server is a server specially designed to resist DDOS attacks. These servers use a variety of technologies and strategies to prevent or reduce the impact of DDOS attacks on network services. High -defense servers usually have powerful network bandwidth, traffic cleaning and filtering mechanism, as well as real -time attack detection and automation mechanism.

　　Some characteristics of DDOS attacks include:

　　Large -scale traffic: DDOS attacks are usually characterized by a large number of network traffic, exceeding normal service processing capabilities. This may include HTTP requests, UDP packets, SYN/ACK, etc.

　　Distributed attacks: Attackers launch attacks by using multiple computers distributed all over the world, making attacks more difficult to prevent. These computers may be infected or may be the server leased.

　　The purpose is to refuse service: The goal of DDOS attack is to make the target system, network or service unable to provide normal services, resulting in unavailable services, called rejection service.

　　The way of high defense servers against DDOS attacks include, but not limited to:

　　Cleaning of flow: Real -time monitoring and analysis of traffic, removing malicious flow, and ensuring that only legitimate traffic is transmitted to the target server.

　　Network bandwidth enhancement: provides high bandwidth network connections to withstand larger attack traffic.

　　Distributed defense: The servers deployed in different geographical locations are deployed to decentralized attack traffic and improve the overall defense capabilities.

　　Automatic response mechanism: When detecting DDOS attacks, automatically start the corresponding protection measures to reduce the pressure of manual intervention in administrators and ensure rapid response time.

　　High defense server is a server designed to deal with DDOS attacks. Through multi -level security strategies and technical means, it aims to ensure the continuity and stability of network services.
