我们经常听到vpn这个词，那么到底vpn是什么意思，vpn是指虚拟专用网络，那么下面小编就给大家介绍一下vpn是什么。
方法/步骤：
VPN是一种通过安全性较低的网络来创建安全加密连接的技术，是为了允许远程用户和分支机构安全的去访问应用程序和资源，接下来将详细介绍什么是vpn。
VPN的含义
VPN称为虚拟专用网络，用户通过唯一身份验证识别程序来访问VPN服务器上的远程资源，为了确保安全，数据通过安全隧道进行 传输VPN服务是安全可靠地传输数据的关键渠道。
VPN如何工作
两种最常见的VPN类型：1、Internet VPN，表示使用互联网线路的VPN；2、IP-VPN，指在每个电信运营商独立构建和操作的封闭网络中使用的VPN。
远程访问VPN
远程访问VPN使用因特网之类的公共电信基础设施来为远程用户提供对其组织网络的安全访问。当我们使用公共Wi-Fi 热点或其他途径访问互联网时，远程用户的计算机或移动设备上的VPN客户端连接到组织网络上的VPN 网关。网关通常要求设备验证其身份，然后创建一个用于返回设备的网络链接，允许它到达内部网络资源例如文件服务器，打印机就像网关在本地网络上一样。远程访问VPN通常依赖于IP安全或SSL来保护连接， 这些需要隧道协议比如点对点隧道协议或第2层隧道协议。
站点到站点VPN
站点到站点VPN使用网关设备将一个位置的整个网络连接到另一个位置的网络，通常是连接到数据中心的小型分支。远程位置中的终端节点设备不需要VPN客户端，因为网关会处理连接。当交换机的安全要求超过企业网络可以提供的安全要求时，VPN服务也可以定义为特定计算机之间的连接，通常是单独数据中心中的服务器。企业还可以在远程访问模式或站点到站点模式下使用VPN连接来连接到服务环境中的资源。
使用VPN的好处
使用VPN访问而不是专用网络的理由通常归结为成本和可行性：拥有专用网络是不可行的，因为成本太高。除了为远程用户提供传输或访问信息的安全方式之外，VPN服务还可用于其他目的。比如VPN可以隐藏用户的浏览活动这对于公共Wi-Fi连接尤其有用，VPN还允许用户连接到可能在地理位置上被阻止的站点。VPN性能可能受到各种因素的影响，其中包括用户的互联网连接速度，互联网服务提供商使用的协议类型以及VPN使用的加密类型等
总结：以上就是vpn介绍的全部内容了，希望对大家有所帮助。
