【正文】 ystem Intrusion Detection Technology is to guarantee the security of puter systems designed and configured in a timely manner to a system to detect and report unauthorized or unusual technology, is a puter work for detecting violations of security policy in the act of technology. Intrusion Detection System in the use of audit records, intrusion detection system to identify any hope that some activities in order to limit the reach of these activities in order to protect the security of the system. On the campus work using intrusion detection technology, the best hybrid intrusion detection, at the same time in the workbased work and hostbased intrusion detection system will be a plete threedimensional framework into the active defense system. d) Web, Email, BBS safety monitoring system Www in the work server, Email server, such as the use of work security monitoring system, realtime tracking and surveillance works, intercepted online Inter transmission, and restore the integrity of the , Email, FTP, Tel application, set up to preserve the corresponding The database records. Found in a timely manner on the work transmission of illegal content, the higher the security work in a timely manner to the center of the report and take measures. e) vulnerability scanning system Network layer to address security issues, first of all to make it clear what work security, vulnerability points. In the face of largescale work plexity and changing circumstances, only work administrators rely on the skills and experience to find security holes, making a risk assessment is unrealistic. Solution is to find a work to find vulnerabilities, and to suggest amendments to the assessment of work security scanning tools to optimize the use of the system configuration and patching in various ways, such as the most likely to make up for the latest security loopholes and eliminate hidden dangers. In the low level of security requirements, using a variety of hacker tools, work simulation in order to attack exposed the vulnerability of the work. f) IP theft problem in the router39。s IP and MAC address binding When an IP router, access through the Inter, the router checks sent to the IP packet radio station of the MAC with the MAC address of the router on the table in line with, if released on line. Otherwise not allowed through the router and at the same time to the issue of the IP packet radio station to return a warning message. g) the use of workmonitoring system to safeguard security The external work intrusion by installing a firewall can be resolved, but the internal work attacks do nothing about it. In this case, we can take on a different sub has a function of the audit documents for the management of its own analysis of the work provide the basis for the operation of state. Design a subwork of dedicated monitoring procedures. The main functions of the software to monitor the longterm subwork of interconnected puters, the system for all of the audit file server to provide backup. In short, is a work security system works, not just rely on a single firewall system, and the need to carefully consider the security needs, and a variety of security technologies, such as technology, bined with the password? Together in order to generate a highperformance, GM , A work security system. China39。s information work security technology research and product development is still in its infancy, there are still a lot of work we need to research, development and exploration, to go with Chinese characteristics, the development of joint research, catch up with or surpass the level of developed countries In order to guarantee China39。s information work security, and promote the rapid development of China39。s national economy.
