面对DDoS攻击 应该如何应对?

现在的战争已经升级成为网络战了,全球DDoS攻击十分猖獗,恶意竞争跟利益是攻击的普遍原因。而且企业一旦遭到攻击就会产生金额不小的损失,甚至关键业务信息丢失,对公司造成负面影响。使用云主机服务器面对DDoS攻击要如何应对呢?

面对DDoS攻击 应该如何应对?

[面对DDoS攻击 云主机如何应对]

  DDoS攻击,全名叫做分布式拒绝服务(Distributed Denial of Service),攻击者往往将多个计算机平台联合起来,对同一目标或者多个目标进行攻击。如今,DDoS攻击日益普遍,且伪装性极强,通常采用大量合法请求的手段以占用服务器网络资源,达到网络瘫痪的目的。服务器在面对DDoS攻击时,很难合理的判定和区分请求,因此遭受攻击时往往束手无策,不得不面对网站停摆、业务中断的尴尬。

  高防部署,降低被攻击概率

  不过,DDoS攻击虽然无解,却可以通过有效的手段来减轻攻击造成的损害,降低被攻击的概率。通过设置网关或路由防火墙,可以对DDoS攻击起到一定的防御作用;也可以采用CDN加速,将攻击分散到镜像服务器上,降低对服务器的影响。然而,面对规模较大的DDoS攻击事件,这些方式都无异螳臂当车,无法达到理想的防御效果。

  攻击来袭,如洪水猛兽,要想困住这头“猛兽”,最大限度地确保网站安全,企业还需部署专业的DDoS防御方案。DDoS高防,主要针对云主机、VPS服务器在遭受大流量的DDoS/CC攻击后导致服务不可用的情况下,推出的付费增值服务。用户可以通过配置DDoS高防,将恶意攻击流量进行清洗过滤,确保主机稳定运行。

  超高带宽 立体防护

  10~500Gb超高防护峰值,轻松应对DDoS、CC攻击,BGP多线防护,全面覆盖电信、联通和移动网络,帮助用户抵御攻击流量,保证业务的正常运行。

  实时监控 秒级防护

  清晰直观的流量实时监控系统,当攻击发生时,清洗中心秒级响应,将攻击流量牵引至清洗中心进行恶意流量的处置,再将正常的业务流量通过隔离的回送通道送达目标网站。

  多重识别 应用层防护

  提供实时具备应用层抗DDoS攻击的能力,多重认证、身份识别、验证码等多种手段精确识别恶意访问和真实访问者,支持TCP/UDP/HTTP/HTTPS,对网站、游戏类CC攻击也可防御。
