高防服务器为什么需要大带宽?

如果大家了解高防服务器主要是用于防御什么攻击,那么大概就会知道为什么需要大带宽了。
什么是高防服务器?

  高防服务器是什么其实很容易理解,就是指独立单个防御50G以上的服务器。能够帮助网站拒绝分布式拒绝服务攻击,并且定时扫描现有的网络主节点,查找可能存在的安全漏洞的服务器类型,都可以称为高防服务器。

高防服务器针对什么攻击?

  从防御范围来看,高防服务器是针对SYN、UDP、ICMP、HTTP GET等各类DDoS攻击进行防护,并且能针对部分特殊安全要求的web用户提供CC攻击动态防御。

什么是DDoS攻击?

  既然说到高防服务器是针对DDoS攻击的,那么什么是DDoS攻击呢?DDoS又称分布式拒绝服务攻击,这种攻击是利用一批受控制的机器向一台机器发起攻击,这样来势迅猛的攻击令人难以防备,因此具有较大的破坏性。

  与DoS攻击由单台主机发起攻击相比较,分布式拒绝服务攻击DDoS是借助数百、甚至数千台被入侵后安装了攻击进程的主机同时发起的集团行为。

为什么防御DDoS需要大带宽?

  DDoS攻击的表现形式主要有两种,一种为流量攻击,主要是针对网络带宽的攻击,即大量攻击包导致网络带宽被阻塞,合法网络包被虚假的攻击包淹没而无法到达主机;另一种为资源耗尽攻击,主要是针对服务器主机的攻击,即通过大量攻击包导致主机的内存被耗尽或CPU被内核及应用程序占完而造成无法提供网络服务。无论是哪种攻击方式,使用大带宽才能够防止网络堵塞和资源消耗殆尽的状况。

  因此,选择高防服务器的时候,不能仅仅看防御能力,还需要注意带宽的大小。RAKsmart提供高防服务器租用,百兆带宽G口接入,带宽资源充足。
