什么是NAC

这项技术有助于企业增强其关于任何寻求网络访问的个人或设备的安全策略。NAC还有助于企业与外部的规章和内部的策略保持一致性，并可以保护网络资源免受不断发展的网络威胁的危害。NAC的目标NAC代表着一种安全产品，其目标可分为以下三个部分：1减少零日攻击风险。NAC方案的关键价值取向在于防止缺乏反病毒、补丁、主机入侵防御软件的终端访问网络资源，并可阻止这种设备将其它计算机置于风险之中。2增强策略。NAC方案允许网络 *** 作员定义策略，如允许访问网络的用户角色或计算机类型是怎样的，并在交换机、路由器等网络设备中强化这些策略。3身份和访问管理。传统的IP网络根据IP地址增强访问策略，而NAC环境根据用户身份来增强安全。NAC的救治策略NAC是为了治病救人。NAC的 *** 作人员部署NAC 产品的目的是为了禁止一些没有采取健全安全措施的客户端访问网络。如果用户会都拥有最新的补丁，并且都安装了防火墙和可升级的反病毒程序，还要NAC干什么呢？正因为如此，NAC要求采取一种机制来救治客户端的问题。NAC有两种救治策略，一是是网络隔离，二是限制网络入口。一个隔离网络是一个受限的IP网络，它可以向用户提供某些主机和应用程序的选择性访问。隔离通常是根据VLAN分配来实施的。当NAC产品认为某一个终端用户“过期”时，其交换机端口就分配给一个VLAN，此VLAN连接到补丁和更新服务器，而不能连接到网络的其余部分。除了VLAN方案之外，还可以采用地址管理技术（如地址解析协议和NDP协议）实现隔离，可以避免管理VLAN的高昂成本。限制网络入口能截获到达网页的>Cisco TwinGig转换器模块，将上行链路从千兆以太网移植到万兆以太网

nac小卡的意思是网络接入控制。nac小卡已经是当前相当重要的控制网络接入的一种手段，它一般通过网络编程来实现，技术含量高，这已经成为思科、H3C、微软等企业的又一商业利润来源。是能够有一种开源的工具来实现nac小卡，nac小卡网络接入控制(NAC)在当今的网络世界中可谓如日中天，其产品仍处于早期阶段。

内条不规范。nac主机升级提示硬件不兼容的原因是内条不规范。NAC与NAP已经结为同盟,即网络接入设备上采用思科的NAC技术,而主机客户端上则采用微软的NAP技术,从而达到了两者互补的状态，生产出的主机深受大众喜爱。

随着信息化的快速发展，对国家、组织、公司或个人来说至关重要的信息越来越多的通过网络来进行存储、传输和处理，为获取这些关键信息的各种网络犯罪也相应急剧上升。当前，网络安全在某种意义上已经成为一个事关国家安全，社会经济稳定的重大问题，得到越来越多的重视。

在网络安全中，身份认证技术作为第一道，甚至是最重要的一道防线，有着重要地位，可靠的身份认证技术可以确保信息只被正确的“人”所访问。身份认证技术提供了关于某个人或某个事物身份的保证，这意味着当某人（或某事）声称具有一个特别的身份时，认证技术将提供某种方法来证实这一声明是正确的。
