CDN和高防IP有啥区别

服务器用CDN和高防IP的区别,大家是否知道?服务器是很容易被攻击的,如果被攻击了,我们要及时应对,那么服务器用CDN和高防IP的区别怎样,使用哪个好呢?

CDN和高防IP有啥区别

  1.IP数量

  高防IP都是一个IP防护,并且是单IP独享,而CDN都是共享IP。而CDN是一组IP防护,而且都是共享IP。

  不能说哪个比较好,但一般高防IP防护能力都是会比高防CDN高些。

  2.误杀率

  高防IP的误杀率远比高防CDN的高,一但高防IP启用严格模式后,会把一些公用IP、WIFI等连接屏蔽掉,而高防CDN误杀率要小很多。

  当然如果你网站被大量攻击有误杀率是很正常的,没有哪家公司敢保证100%零误杀但是希望的是能减少损失。

3.隐藏源站

  高防CDN对外暴露的是各节点的共享IP地址段,通过CDN节点IP实现对源站的业务转发,攻击者无法通过业务交互获取真实的用户源站,从而保障了源站的安全。

  4.业务方向

  高防CDN主要是针对网站业务,主要是通过域名访问的防御,所以限定开放端口是80、443,这两个端口主要是HTTP和HTTPS的端口,因此使用其他端口的业务是不能使用高防CDN的。

  高防IP针对的是服务器的IP防护,而不是域名,所以支持的业务比较多,像APP、网站业务、游戏、软件等都是可以的。而且高防IP是支持全端口转发的,可以自义端口转发防护。

  5.防御类型

  高防CDN在针对URL的DDoS攻击时,流量会被DNS调度,分散到各个CDN节点,充分利用全网带宽实现有效的防护。另外高防CDN一般都带有WAF防火墙,可以拦截一些扫描漏洞,还有PHP漏洞等。但是高防CDN节点的防护能力一般在20-100Gbps之间,如果攻击者绑定HOST来指定节点进行攻击,或者针对各节点IP轮流发起攻击,只要攻击流量超过单CDN节点的防护能力,则会造成单CDN节点所有业务服务出现中断,如果攻击者针对CDN节点依次发起超大流量攻击,则会造成用户的业务在节点间不停地切换(单次切换时间大约在2-5分钟),甚至会导致整个服务出现中断。

  高防IP服务针对不同客户的需求,一般提供一个或者多个高防节点来对客户业务进行防护,客户所有的流量都会收敛到高防节点,只要攻击流量小于节点的最大防护能力,节点都能轻松应对。高防IP只能防御DDoS和CC攻击,而对于一些扫描漏洞之类的是没办法防御的。高防IP防护DDOS攻击能力是要比CDN高的,一般高防IP都是防护30G峰值以上,而CDN的话普遍在10G-30G,高于30G以上的价格都是比较昂贵的。

  6.网站加速能力

  高防CDN节点一般会按省份按线路进行分布,业务流量一般会通过DNS智能解析来进行调度,用户可以通过最优的CDN节点来访问业务网站,CDN节点可以对业务网站中的静态资源进行加速,因此用户的访问时延会大大降低,体验会比较好。

  高防IP的节点一般在10个以内,无法像高防CDN一样,通过各省提供的CDN节点为网站加速,但是高防IP也可以提供多个大区节点,对业务的静态资源进行缓存加速及按照大区或线路进行DNS调度,可有效减少对源站带宽资源的使用,及实现按大区或线路近源访问的能力,但是加速效果比高防CDN稍差。
