Computer operating system safety protecting method

Abstract

The method adds database of digital signature and certificate, module of security management and module of security agreement on Unix operating system (OS) at user level, and adds an access control module of digital signature authentication on Unix OS at kernel level. Without changing executable files of system and kernel, the method makes the each added module become an effective section of OS so as to be able to carry out security protection and effective control for whole Unix OS under condition of without rewriting operation and condition of transparence. Advantages are: simple, safety, practical and reliable.

Description

1. Technical field [0001] The invention relates to a computer application technology, in particular to a computer operating system safety protection method. 2. Background technology [0002] With the extensive and in-depth application of the Internet, the issue of information security has increasingly attracted people's attention. [0003] Currently common network security solutions: mainly use firewalls, intrusion detection systems, anti-virus and other security products. Network security is a systematic project, and the above-mentioned products can only address one aspect and solve some security problems. At present, many hackers also use a variety of methods to attack. If only one aspect of security problems is solved, real security cannot be achieved, so a systematic solution is necessary. [0004] Each security technology or product has a certain security effect. For example, the intrusion detection system can detect many intrusions. However, it should also be aware t...

Problems solved by technology

In a network environment, the security of the network system depends on the security of each host system in the network, and the security of the host system is determined by the security of its operating system. Without the support of a secure operating system, network security no foundation
