1.安全的新形势:终端成为新的边界传统的网络安全模型中,将网络划分为内网、外网、DMZ等多个安全域,通过在网络边界部署防火墙来隔离内外网。随着信息网络技术的发展,网络安全的势态发现了变化。一个明显的特征是:终端成为新的网络边界。首先,随着网络接入技术的发展,终端接入网络的方式已经不再局限于局域网接口,包括
1. The New Security Situation: The Terminal Becomes a New Border In the traditional network security model, the network is divided into multiple security domains, such as intranet, extranet and DMZ. The firewall is deployed at the network border to isolate the intranet and extranet. With the development of information network technology, the trend of cybersecurity has found a change. One obvious feature is that the terminal becomes the new network boundary. First of all, with the development of network access technology, the way that the terminal accesses the network is no longer limited to the LAN interface, including
