Types of High-Defense Servers

As network security is becoming more and more important, high-defense servers have become the first choice of more and more enterprises. High-defense servers can provide enterprises with more stable, safe, and fast services. Before we get to know what types of high-defense servers there are, let's first understand the function of high-defense servers.

Function of High-Defense Servers

A high-defense server is a server with DDoS firewall installed, which can protect the enterprise's network security through functions such as DDoS attack defense, website acceleration, and load balancing. Attackers often use a large number of IP addresses to launch DDoS attacks against specific servers, making them unable to work normally, thus affecting customers' use and enterprise operation. High-defense servers have powerful resistance to such attacks and can ensure the normal operation of enterprise business.

Types of High-Defense Servers

High-defense servers can be divided into the following types according to their uses:

1. DDoS high-defense server

The DDoS high-defense server is a server specifically designed to resist DDoS attacks, which can ensure the security of the enterprise's network, site stability, high-speed response time, and other important business. The advantage of a DDoS high-defense server is its ability to resist large-scale, long-time attacks, and also ensure service stability.

2. CDN high-defense server

The CDN high-defense server is an enhanced version of the CDN server, which can provide a certain level of defense for enterprises while serving them. The CDN high-defense server can ensure the high speed and stability of CDN service, as well as the ability to defend against DDoS, CC, and other attacks for enterprises.

3. WAF high-defense server

The WAF high-defense server is a server with web application firewall capability, which can intercept web attacks, SQL injection, XSS, and so on. The WAF high-defense server can ensure the security of enterprise web applications and improve the level of enterprise network security.

4. Secure public cloud high-defense server

The secure public cloud high-defense server is a cloud defense service based on cloud computing provided by cloud security vendors, which can provide DDoS defense, WAF defense, SSL encryption, and other services for enterprises. The secure public cloud high-defense server has advantages such as flexible deployment, high efficiency, and low cost, and can be customized and managed according to the actual needs of enterprises.

Conclusion

High-defense servers are one of the important measures to ensure enterprise network security, and different types of high-defense servers are suitable for different application scenarios. Enterprises should make reasonable choices when choosing high-defense servers based on their own business needs and risk situations.
