RAK部落警示:租用高防服务器暴露源IP会怎么样?

今天,给大家分享这个话题,主要是为一些个人和中小型网站站长提个醒,大家所使用的中小型服务器一旦被人恶意攻击基本就是玩完了哦。有位朋友问问题的时候将自己的服务器真实IP暴露出来了,当时也是出于习惯,就随口提醒了一下他。但是后面的一位朋友却说ip又没什么秘密,意思也就是:暴露就暴露了,没什么问题。

当时心里一咯噔!这一定是个有钱人!要么就是一个毫无安全意识的人(虽然本人的安全意识一样很薄弱)

一、为啥隐藏真实 IP?

为什么这么说?这就得从“暴露真实IP会造成什么不好的后果”这个问题说起。

1、源IP暴露,不法者会通过DDOS、CC攻击你服务器,如果没有用高防服务器,一打就挂。

2、杜绝了网络上那些到处扫描端口、扫描漏洞、被人入侵,爆库等等危险的行为发生。举例:

在很久一段时间之前的某个晚上,本人的手机和邮箱连续收到多个RAKsmart的警告通知,最后直接把我关小黑屋了。只要你ecs在的机房有用户暴露ip被人盯上了,整个机房网段都别想安宁了,ntp攻击直接机房入口给你堵上,然后直接算到你ddos头上,哪怕你服务器彻底关了都没用,只能重买新的换ip然后释放掉现有的.

至于被谁打的,谁又知道呢。

看到这儿,或许你就不耐烦了,说这些跟IP暴露不暴露有什么关系?我想说的是,当然有关系。

二、如何隐藏真实 IP?

我们都知道,使用诸如RAKsmart、Aquanx的CDN等等的目的一是为了缓解自身服务器的带宽压力,增加访问速度,再一个就是为了防止别人恶意的DDOS攻击。这是因为,使用了CDN后,正常的请求过程为:

用户请求 –> CDN节点 –> 源站服务器

也就是说,CDN作为中间层已经将我们网站的请求,分配到了各个分布式大带宽的节点上,这就保证了我们的网站能免受一些小流量的ddos攻击。如何你的网站上没有使用cdn或其他反向代理的工具,那么接收一个请求则是最简单的一个过程:

用户请求 –> hosts解析 –> 源站服务器

这时候的请求是直接作用到源站服务器上的,如果此时从某个地方对我们的服务器发动ddos攻击的话,所有的流量都会瞬间直达我们的服务器上,试想一下,如果我们的服务器配置不高的话,那会是一种什么下场。

使用CDN技术隐藏真实IP也是有所不足的,在服务器上发布的内容无法及时的进行更新,CDN是存在地区限制的。例如只是做了国内的CDN,而没有做海外的CDN,这样坏蛋使用美国服务器的IP,在使用某些工具ping 的域名或其它地址那么亲们的服务器真实IP真实就出现在坏蛋面前了。

目前,RAKsmart推出了“CC防御”,只要购买高防即可获得CC防御资格,感兴趣的朋友可以了解一下“raksmart10月钜惠”活动。

      I’ve been browsing online greater than 3 hours as of late, but I by no means found any attention-grabbing article like yours.

      It’s lovely value enough for me. In my opinion, if all website owners and bloggers made good content as you did, the net will be much more helpful than ever before.

      Thanks for revealing your ideas listed here. The other thing is that whenever a problem develops with a personal computer motherboard, people today should not have some risk connected with repairing this themselves because if it is not done properly it can lead to irreparable damage to all the laptop. It is usually safe to approach the dealer of that laptop for your repair of its motherboard. They have got technicians who've an knowledge in dealing with laptop motherboard problems and can make the right prognosis and undertake repairs.
