The Lans-Monintoring System Based On The Winsock

The 21^st century is an era of information and network economy. The widespread of computerization and the rapid development of network technology have turned information safety a major researching object. Information leakage and theft have also turned computerized crime to network crime or information crime. Network safety has become the focus of IT area.This paper designed a LAN control system based on Winsock, to enhance the control for network information, and ensure the security of network contents distribution. At first, the paper started with present network security problems, then, analyzed the various existing network technology and its limitations; furthermore, raised the necessary of LAN real-time monitoring based on Winsock; in addition, raised a LAN real-time monitoring system model based on domestic and international situation and development needs of the system functions. This paper introduced the main function of each module in the system model, and focus on expounding and explaining various key technologies within the realizing process.Experiments show that the use of Winsock control, may encapsulate all the tedious technical details, and offer facilitate accesses to visit TCP and UDP network services, thus, ensured the system's stability and reliability. Practices have proven that through every computer screen for inspect instant picture and operational procedures to grasp the employees' work situation, but also categorize and keep all computer screen snapshots, moreover may conveniently rapid access and replace history record. Through LAN monitoring software may allows you grasp the company information security and achieve prevention in advance, on time prompt and forbidden, as well as afterwards effection tracking.
