Design And Implementation Of Remote Monitoring System For E-mail,

Aiming at researching and realizing distributed monitor on email, the system is mainly applied to collect, analysis, filter and control on such actions as computer crime, hacker attack, information spy and information intrusion and so on. Accordingly it can control specific message and behavior by detecting, alerting and managing on security status of some network. The system adapt such mode as client/server , including soft client server and email monitor center. Soft client is secretly installed on ISP, WAN, host computer of important and sensitive part needed to be controlled to collect network data. After transmitting in real-time to email monitor center, POP3, information such as SMTP and Web -mail from these data are analysised and retrievable, password intercepted, classified and alert, And the monitor center can control working status and filering condition and software refreshment etc. of soft client. The system monitor different netwoks because of distributed dealing arithmetic. While nodes are distributed reasonably, the center can monitor in real-time on over 1000 nodes by controlling working status and filter condition The system occupies less than 4 percent of system resource under the condition of without losing package. The writer mainly carried on system design and research of applying mode and some other testing task. Also At present the system has been put into practical use and has a good effect on information control.
