在如今网络安全问题频发的时代，各种层出不穷、令人防不胜防的网络攻击随时都有可能爆发出来，正是在这种复杂多变的背景环境和情况下，现在市面上的“高防服务器”越来越受到更多企业用户的重视和青睐。
高防服务器，简单的来说，就是自带一定防御能力的服务器，是指独立单个硬防防御能力50G以上的服务器类型;能够为用户防御DDoS攻击和CC攻击，为用户提供网络安全维护的服务器类型。
In general, high anti-server functionality in addition to have common server, also has the ability to "attack prevention, anti-virus" and other areas, for most types of network attacks have some protective effect. Now, although there are many users out of consideration for the business stability and security of the site, choose to rent "high anti-server" to reinforce the defense, but their defense of the principle of high anti-server and the ways in which the main defense, do not quite understand .
To introduce and summarize, defense high anti-server principle and its main defense what way, I hope you can help deepen knowledge and understanding of high anti-server.
Defense high anti-server principle
now, the vast majority of high anti-server market, mainly by implementing the "network level" and "physical level" of protection to help protect users from a variety of network attacks, and maintain their own security server .
1, network defense
有一种高防服务器，主要是针对网络防御进行加强的服务器。这类高防服务器，在硬件上与普通的服务器是一样的，只不过在技术上，进行了专门的 IP 隐藏设计，使得外界的攻击没有办法直接攻击到该服务器，这也是一种很有效的防御措施和原理。
2, physical defense
一般来说，我们通常所接触到的高防服务器，指的都是物理防御，也就是直接在服务器的硬件上面，增加了一层硬件防火墙。这样的硬件防火墙，无疑就像是服务器一层厚重的“盔甲”，可以起到非常良好的防御作用。所以一般默认的高防服务器，就是这类添加“硬件防火墙”进行物理防御的高防服务器。这种高防服务器，能够使得通过在物理硬件层面的加持，让用户享受到更加安全、良好和显著的防御效果。
