网站到底该怎么做好防御呢,这是许多站长的心中一大疑问,云漫网络接下来将会为你解疑难。
在传统的动态系统的访问中,用户对网络的请求过程,一般需要经过网络中多台路由器的传输,终将发送的请求交于动态系统来处理,但是由于IP网络本身的“尽力而为的原则”、网络链路中复杂的环境及硬件的不可靠性的确实存在,致使用户要出现重复发送的请求的现状,所以终导致用户的请求在提交的过程中出现等待、数据加载时间过长的一些现象的普遍存在,这些在线提交式系统的缓慢直接地影响到办公人员的工作效率,这也是制约着很多大型企业在协同办公OA、ERP、SAP等信息化建设中,出现多的问题。
而CDN分发解决方案解决了与静态网站相关的性能和可靠性问题,而在当今在线业务体验中,与分发静态和动态元素和应用相关的独特挑战,则由速网的网站加速来解决。

1.搜索引擎劫持
搜索引擎劫持简称搜索劫持,其实就是从搜索引擎来的流量自动跳转到指定的网页。可以通过未经用户授权,自动修改第三方搜索引擎结果的软件实现,通常这类程序会在第三方搜索引擎的结果中添加自己的网站链接获取流量等,主要包括关键词劫持和快照劫持。
比如关键词劫持,假如你在百度搜索某网站关键词,结果百度搜索后的结果是正确的,但是点击进去之后却跳转到别的另一个网站上,并且此类劫持方式之后针对一部分关键字进行跳转,劫持方式比较隐蔽。
2.DNS劫持
DNS劫持又称域名劫持,通过攻击互联网上的DNS服务器,伪造DNS服务器,指引用户指向错误的一个域名地址。简单的说就是DNS服务器被更改了。这种情况下你可以尝试域名DNS查询工具识别或全国Ping,一般都可以看到没有按照你的要求指向的,造成特定的网络无法访问或访问的是别的网址,都是被劫持的。
3.客户端劫持
客户务端劫持也称为全局劫持,手法为修改网站动态语言文本,判断访问来源控制返回内容,从来达到网站劫持的目的。
客户端劫持的手法也很多,但主要就是两种:js劫持和HeaDer劫持。
简单来说,是客户端访问网站时,以及客户端从网站上进行下载文件是,出现的数据异常问题。

下面针对于网站被劫持了的常用的预防办法:
1.做好网站程序的保护工作

如果不太理解,可以去查看互联网技术类贴吧,都会有一些处理措施说明以及更新新版本的方法。
2.做好每天的网站勘查工作
除了检查网站的数据内容之外,还要检查网页源码。
学会使用搜索引擎指令先有时间发现隐藏的隐患,及时删除修改。
3.网站时刻做好备份
网站负责人要养成定期备份的习惯,不要等到网站被劫持了,才发现网站数据没有备份,后果不堪设想。
对于网路防护,我们不能掉以轻心,在做好预防网站劫持工作的同时,还要为网站配合适的防御劫持助手。
