Research In Classified Host Information Inspecting And Control System Based On Java

The safety of classified host information is an important part of network information security. In this paper, the classified host information inspecting and control system was researched, designed and implemented to prevent classified host information from being blown the gaff.At present, in some commercial classified host information inspecting and control systems, technologies of connecting control, data check and log audit were commonly used, but the measures that protects classified information itself were less emphasized. Also in these products the definition of classified information wasn't flexible, and some were over extensive, some were over narrow. As a result, more computer resources would be used up, or some classified information would break away from monitoring. Therefore, the solution was put forward, which kept classified host information from being broken by making use of both text classification technology based on string-match and cryptology.In this paper, partial theories and technologies of pattern recognition were discussed. Some principled advices to select classified characteristics of classified host information were brought forward. The string-matching algorithm was specially studied. The different algorithms have been tested many times to select a right algorithm for...
