　　如何降低域名被恶意泛解析的风险

　　域名被恶意泛解析是域名安全最常见的问题之一，服务商往往起到决定性作用，那么作为站点自身该做哪些工作呢?SEO从业者洪石陈管理着多个当地媒体站点，虽然他说自己是网站安全领域内的小学生，但还是很愿意分享一些网站安全工作的心得。百度站长平台特意向洪石陈约稿，请他来分享一下站点如何从自身出发降低被泛解析的风险，下面就是他的反馈内容，希望可以帮到各位站长，同时也欢迎更多网站安全专家在百度站长平台进行分享。

　　一，域名泛解析成因

　　1、站点自身问题

　　1)站点在域名服务商网站注册的帐号密码过于简单，帐号密码被盗，导致域名信息被恶意篡改。

　　2)站点在各http://www.51cbsw.com/6571k1/g7h3e3/种与域名有关的服务端注册时，使用了相同的帐号和密码，被heike破解一个密码后顺利劫持域名。

　　3)现在很多域名解析平台支持泛解析设置，如图1所示，在添加A记录时，主机记录若填写“*”，就实现了泛解析，一旦域名被劫持，就会快速在域名下生成众多二级域名、三级域名。

　　2、域名服务商问题

　　1)网站被攻击，heike盗取众多注册用户的信息。

　　2)域名http://www.rocasmart.com/jikebe/7ccik0/chc7i6/服务商的安全漏洞导致域名被恶意篡改，甚至出现过域名服务商设置了域名锁之后，域名持有人无法修改信息，heike却可以通过漏洞进行域名解析的修改。

　　二，降低域名恶意泛解析，从自身做起

　　1、多从安全角度出发，选择专业可靠、技术能力强的域名注册商，即使他的收费会贵一点。

　　2、选择域http://www.chibianyq.com/ihjdad/b2cj9j/k104bh/名注册商时，详细咨询客服注册商对域名被劫持等安全问题是否有解决方案，之前的安全问题是如何处理的。

　　3、与域名http://www.qingzhisoft.com/j0a652/1007/相关的帐号密码尽量复杂，一定不能使用弱口令(123456之流)，且与域名相关的多个帐号密码不要使用相同组合。

　　4、进行域名解析设置时，如果没有特殊需求，一定不要使用泛解析功能，可以在决定使用哪个二级域名时再进行单http://www.027dcdv.com/hgic9c/kbc4ce/jk54i2/个二级域名的解析操作。

　　5、建议使用百度云加速，享受高防智能DNS，免费的。百度云加速可以隐藏网站真实IP，如图2图3所示，ping网站时http://www.long-kun.com/a9i6gi/1005/显示的是IP地址是通过百度云加速DNS解析的IP地址，即百度IP地址，隐藏网站真实IP地址，提高网站安全系数。
