Design And Implementation Of The Network Remote Access And Control System

With the rapid development of Internet,the Internet-based remote monitoring and controlling technology has developed rapidly.The Internet-based remote monitoring and controlling system refers to that local computers monitor and control the remote production system through the network.Network traffic anomalies are an important aspect of network monitoring.Monitoring and controlling technology based on the whole network traffic mirroring,on behalf of the abnormal traffic monitoring technology,is the main pattern of network traffic collection of the IDS.Its principle is that realize the lossless replication and mirroring collection of the network traffic,through the mirror port of the switches or routers.Compared with other traffic acquisition methods,the monitoring and controlling technology based on the whole network traffic mirroring,not only can provide a wealth of application-layer information,and it positions itself in the role of third-party network monitoring,will not increase the network traffic,will not burden the network performance.It has so many technical advantages.Based on a network security monitoring project,not only with the technical ideas of the third-party network monitoring technology based on the whole network traffic mirroring,but also with the human-computer interaction approach of the Internet-based remote monitoring and controlling technology,a network remote access and control system has been developed in this paper.It provides the network supervise with a good monitoring tool.First of all,with the network remote monitoring system and network monitoring technology studied in-depth,a topological model of the system has been buildded.And then with client/server model discussed in detail,combined with the system working pattern,the client/server architecture has been selected for the system's design.Moreover,the system's design uses a dual-channel mode,with command channel and data channel been designed separately.Next,in accordance with the idea of modules division,the detailed design and realization process of the command channel and data channel has been introduced.And with the command transmission protected with DES encryption,the data transmission protected with the X509 certificate encryption,the security of the system has been improved greatly.Finally,the actual operation and test results of the system have been given,and future prospect of the system has been made.Based on the socket mechanism and database technologies,the system can monitor and control a router or a switch remotely.And the monitoring and analysis data of the system can be accessed and transmissed remotely.Through the system,the network supervise can view and handle the network monitoring results in real-time.Then they can take timely measures for the network to isolate and control the harmful traffic,so that they can protect network security much better.
