The Research And Implementation Of Host Security Detection System

With the rapid development of computer network technology, network began to permeate all areas of society. Among this vast network, the basic node that supports the normal operation of the system is the network host. These hosts include servers, routers, switches, personal computers and so on. However, these hosts have varying degrees of security risk. In order to better protect the security of the network hosts, we need to detect the host's security first, and find out what kind of security problem existing in the hosts.At present, there are two main methods of host security detection. One is detection by using automated vulnerability scanning tools, the other is manual detection. Automated scanning tools are limited in scope; while artifical detection ofter relays on the inspectors'technology, experience, and it has low efficiency.Therefore, we study the host security detection methords, design and implement a semi-automated host security detection system. This system is based on Browser/Server structure. The system can complete the inspection of the host's security vulnerability that exist in operating system configuration, system parameter, user access permissions, account/password, file access, log files and other aspects of the security vulnerability.This paper gives the comprehensive description of the host security detection system from designing to implementation. The specific work is as follow:1. Investigate the background of host security detection;2. Design the Content Library of host security detection system;3. Design the host security detection system;4. Host security detection system detailed design and implementation of key modules;5. Functional testing of host security detection system.The system has been approved, and deliverd, and achieved good results. This work pioneered the concept of host security detection systems, and it can provide a reference for the host security detection system design and implemention.
