Design And Implementation Of Network Security Detection System

With the development of computer network technology and popularization, more andmore enterprises use the computer information system in the daily management.Management of information technology improves the work efficiency, in the other side，introduces security risks and management issues. Such as sensitive data is easily leakedthrough the network, how to strengthen the internal network security management,establish a strict auditing system is the key to guarantee the security of the internalnetwork. In addition to the internal management, the deployment of network securitymonitoring system is an important technical means for internal network security.Monitor the work state of the internal computer and through the real-time informationby monitoring computer, managers can get the condition of the monitored computers, inorder to achieve safety monitoring and management for the internal networkenvironment.This thesis introduces the working principle of network security monitoring system,analyzes the key technologies involved in the system development process, includingthe network programming technology, Windows API Hook technology, and then givesthe overall system architecture. The processing of monitoring function is designed, andhow to use VC++language to implement the process system are described. The systemcan achieve the access on the computer network, file system operation, system stateinformation of remote access and real-time monitoring.The results of testing and analyzing show that the system achieves the desired designgoals. It can meet the functional requirements of the internal network securitymonitoring，and it can be applied to network information security for environment ofenterprises and institutions.
