<p ></p> 
<p>处理 ddos 攻击的最少成本是防止 &#xff0c;不要等到攻击到来再防御 &#xff0c;首先成本远超攻击前的防御 &#xff0c;因此 当ddos 攻击开始时防御 &#xff0c;不但会造成 高额成本 &#xff0c;如果有把柄在黑客手中 &#xff0c;就更加 麻烦了&#xff0c;所以事前防御才是上上策 。</p> 
<p>想避免 DDOS 攻击 &#xff0c;务必先搞清楚 &#xff0c;当今销售市场 99 %的DDOS攻击是对于 IP 以百G攻击流量导致网络服务器瘫患&#xff0c;以便做到攻击目地 &#xff0c;因而 你务必防止服务器ip泄漏并掩藏 源ip &#xff0c;那样黑客就无法找到源服务器ip &#xff0c;也没法使用ddos有效地攻击你。</p> 
<p>根据隐藏源服务器 IP 的思路 &#xff0c;我们可以给业务做一个高防CDN&#xff0c;既可加速 &#xff0c;又可以预防 被DDOS 攻击 。高防CDN能够做到掩藏源服务器目地 。当查询 IP 时只能查询 高防cdn的节点 &#xff0c;而CDN 节点这般之多。 即便他人想攻击你&#xff0c;也必须得一个个的IP 去打&#xff0c;这样造成的攻击成本自然就提高 &#xff0c;对他们来说完全不划算 &#xff0c;而且还未必能找到 。当然不仅要做到 源IP不暴露 在防御上也是就近机房清洗 &#xff0c;回源速度快 &#xff0c;丝毫不影响用户体验 &#xff0c;不过值得一提的是不要把域名直接解析到源站IP &#xff0c;也不要用源服务器 IP 直接进行访问 。</p> 
<p>许多网站管理员都等网址被攻击了才上高防cdn &#xff0c;因此沒用&#xff0c;由于另一方早已记住了你的ip &#xff0c;直接绕过高防CND节点 。根据源ip攻击你&#xff0c;怎样防御 &#xff1f;所以在接入防护之前一定要确定源IP 是干净的&#xff0c;否者就要申请更换公网IP</p> 
<p>因此&#xff0c;避免腾讯云服务器遭受ddos攻击的最好是方式就是说 把高防CDN布置在好&#xff0c;不能让另一方 了解 你的源服务器ip &#xff0c;即便 高防cdn 其中一个节点被打死 &#xff0c;还可以立即切换到其他备用节点上。</p>
