摘要
S-UNIX是一个基于UNIX的安全操作系统,其目标是TCSEC的B2级以上且保持与UNIX的兼容性,本文从存取控制、审计、可信进程管理、病毒防御、隐通道分析处理、可信通路建立六个方面,介绍了S-UNIX的研究与设计,S-UNIX基本系统在386微机上初步运行表明,它极大地提高了UNIX的安全性,并能够保持与UNIX的兼容性。
S-UNIX is a secure operating system based on UNIX,whose targets are the B2 or higher level of TCSEC and keeping compatibility with UNIX.This paper in- troduces S-UNIX from six aspects:access control,audit,management of trusted software,prevention of virus,trusted path,and analysis and solution of covert channels.The preliminary running of S-UNIX on 386 microcomputer system shows that it greatly enhances the security of UNIX,and can maintain compatibility with UNIX.
