基于NDIS-HOOK与SPI的个人防火墙研究与设计

Research and Implementation of Personal Firewall Based on NDIS-HOOK

介绍了NDIS系统结构以及在Windows2000/NT下NDIS HOOK的原理,并给出了一个基于NDIS HOOK技术的个人防火墙驱动程序———Packet.sys。利用该驱动程序与SPI技术相结合,可方便地实现基于Windows的个人防火墙。

Introduces the system structure of NDIS and principle of NDIS-HOOK in Windows 2000/NT,gives a drivers-Pac-(ket).sys,which based on NDIS-HOOK.We can combine this drivers and SPI to implement personal firewall easily in Windows system.
