Designing And Implementation Of Remote Security Monitoring System For Networking Servers

With the increasing development and prevalence of the Internet technology, computer network is now playing the more and more important role in the finance, correspondence, manufacturing industry, servicing business and other fields. And with the larger scale and more complicated structure of the computer network, many kinds of MIS (management information system) and e-commerce system begin running on the web, more and more server hosts are now being applied in the Web environment. But at the same time, the destructive behaviors of hackers on Internet is becoming more and more furious, and frequently bring disastrous damage to e-commerce system, especially in these recent years.. Surprisingly, the hackers ever attacked on some well-known web sites without any worry. As a result, so many servers got into paralysis and could not work normally. So, how to effectively monitor network servers and ensure that all service run well will be crucial.At present, the popular approach to manage network equipment is based on Simple Network Management Protocol (SNMP). However, SNMP requires that the managed hosts must support SNMP and have SNMP agent system. The advantage of this method is not in controlling but in monitoring.Besides, Telnet is another method that is applied in monitoring remote servers. It demands that any user should log in remote host by client of Telnet. After entering, the identity will be transferred into root and then the monitoring operation can begin. Because the popular network operating system (Windows, Linux, Unix, etc) almost support TCP/IP, hosts are usually equipped with Telnet server and may offer Telnet service. But the whole course has to be operated by hand and cannot automatically be accomplished.The paper designs one Remote Security Monitoring System. At the onehand, it supplies administrators one interface based on web browser to avoid troublesome manual operation; at the other hand, it directly makes use of Telnet service installed on remote monitored servers, and implements remote controlling and monitoring by Telnet. It is convenient that any extra software does not need to be installed on the remote servers previously.That the system manages remote hosts by strong Telnet, not modifying the soft and hard configuration and environment, makes great signification to improve the efficiency of servers, strengthen network system security, and the like.
