Research and Application of Network Access Control Technology in Enterprise Park Network

网络准入控制(Network Access Control,NAC)是一种新型的安全防御技术,通过对终端实施身份认证、安全检查、权限分配来有效解决因不安全终端接入网络而引起的安全威胁,保护网络的安全。本文结合在工业企业部署的网络准入控制系统的实际应用,研究分析其技术背景、实施过程、实施效果等,介绍了一种新型网络准入控制技术。

Network access control(NAC)is a new type of security defense technology.It can effectively solve the security threats caused by insecure terminals accessing the network and protect the security of the network by implementing identity authentication,security check and authority allocation.Based on the practical application of network access control system deployed in industrial enterprises,this paper studies and analyzes its technical background,implementation process and implementation effect,and introduces a new network access control technology.
