基于安全心理学的主动式防火墙设计

当前防火墙的防御策略为被动防御 ,它只能被动等待攻击者的攻击 ,直接降低了其安全性能。从安全心理学的角度出发 ,分析了被动式防火墙的弱点并设计了一种新型防火墙。该防火墙采用主动式防御策略 ,对于在防火墙中识别出的非法访问 ,通过重定向 ,引导至识别区来保护主系统 ,降低攻击者的攻击欲望 ,从而提高了防火墙的安全性能。防火墙中关键技术为攻击识别技术和重定向技术。

Design of Active Firewall Based on Safety Psychology

Nowadays, the defense strategy of firewall is passive. It would wait the attacker to attack passively. Referring to safety psychology, the vulnerability of firewall is analyzed. A new firewall is presented. When the firewall finds visits that are not allowable, the firewall will redirect these visits to the recognition area, so that the main system is protected. The key technologies in the firewall are attack identification and redirection.
