网络攻击对企业服务器造成了很大的危害，严重会直接影响到业务的正常开展。因此采用高防服务器租用就成为许多企业的主要选择。但是由于企业对于高防服务器的认知不足，就会产生许多错误的认知。今天，小编就来为大家详细的介绍一下这方面的知识。
　　错误观点1：可以防御任何攻击

　　高防服务器主要是通过防火墙和防御策略进行网络攻击防御。防火墙主要是将内部网络和公网分开，将外网攻击进行隔离。对于当今日益复杂的DDOS攻击还不能做到完全防御，但是对于流量型的攻击可以进行有效的流量清洗和恶意流量的牵引，做到保护源服务器的安全的作用。

　　错误观点2：CDN可以提供DDoS攻击保护

　　通常情况下，CDN是无法区分正常流量和攻击流量的。CDN的首要目的并不是提供安全性，而是缓解网络拥堵问题，能够在一定程度上缓解一些攻击，但绝不是所有攻击。

　　如果要利用CDN来防护DDoS攻击，除非你的CDN服务中包含DDoS攻击清洗工具。无论如何，CDN本身不可能提供针对当前DDoS攻击的全面保护。

　　错误观点3：流量峰值阻止DDoS攻击

　　实际上，流量峰值警报无法阻止DDoS攻击，它只是报告你危机正在发生。当警报服务注意到DDoS流量高峰并且您开始处理后果时，可能已经过去了20到30分钟。

　　在此期间，您的网站或应用程序将关闭，并需要由专家进行恢复。此时黑客还有可能窃取您的数据或进行更多其他潜藏的恶意活动。

　　错误观点4：DDoS攻击是打垮整个企业

　　这个认知是错误的，只有极少数的目的是为了打垮企业，大多数的网络攻击主要是在特定时间内中断服务器的访问，让正常的用户无法进行有效的业务活动以及勒索或作为更严重潜藏活动的掩护。

　　高防服务器是目前针对网络攻击最为有效的防御设备，但是也不是全部的网络攻击都可以进行防御，还是需要结合攻击的类型，防御的策略进行调整。
