“防火墙”一词起源于建筑领域，用来隔离火灾，阻止火势从一个区域蔓延到另一个区域。引入到通信领域，防火墙这一具体设备通常用于两个网络之间有针对性的、逻辑意义上的隔离。当然，这种隔离是高明的，隔离的是“火”的蔓延，而又保证“人”的穿墙而过。这里的“火”是指网络中的各种攻击，而“人”是指正常的通信报文。.........【阅读全文】

什么是HTTP？HTTP协议有哪些风险？由于 HTTP 本身是明文传输，用户和服务端之间的传输内容都能被中间者查看。也就是说你在网上搜索、购物、访问的网点、点击的页面等信息，都可以被「中间人」获取。隐私泄露的风险比较隐蔽，用户基本感知不到。但另外一类劫持的影响就非常明显非常直接了——页面劫持，也就是.........【阅读全文】

在实际的DNS解析过程中，用户请求某个网站，浏览器首先会查找本机中的DNS缓存，如果DNS缓存中记录了该网站和IP的映射关系，就会直接将结果返回给用户，用户对所得的IP地址发起访问。如果缓存中没有相关记录，才会委托递归服务器发起递归查询。如果攻击者通过控制用户的主机或者使用恶意软件攻击用户的DNS.........【阅读全文】

普通的DNS解析往往只具备单个解析节点，所以不会去判断用户的IP地址和运营线路，而是会统一将所有用户都解析到固定IP之上，这就可能导致因为跨地跨网而造成解析和访问的延时，影响用户的访问体验。比如A用户是北京联通的用户，那么智能云解析就会将域名对应的北京联通IP返回给A用户；如果B用户是深圳电信.........【阅读全文】

但在实际的解析过程中，并不是客户端的每一次访问都需要委托递归服务器进行迭代查询，而是先搜索浏览器自身的DNS缓存，如果有，解析到此为止；如果DNS缓存中没有结果就会读取操作系统中的HOSTS文件查找对应的映射关系，如果有到此完成；如果没有，再请求递归服务器，进行全球递归查询。从中我们可以看出DNS缓存是获取域名.........【阅读全文】
