The Research Of Information Audit System Based Component

Along with the expansion of IT application, the content which the information audit pays attention from is pure to the electron processing, extends to the computer system reliability, the security carries on the the appraisal. The information system itself security becomes foundation, in the information audit process, needs the effective information security strategy and the securitytechnology to protect the system the security. The traditional information security guard measure often is based on the network communication and the transmission level. Below, the existing measures generally exists the insufficiency:(1) Attention level is unitary: attention to the network communication and data transmission mainly.(2) Lacks security measure to the applications.(3) Cannot process the internal personnel' s malicious attack who registers the system by a legitimate role.We aimed at the insufficiency of the existing technical measure, proposed the thinking of APA (application process information audit). Through the gaining, analyzing to the trace of the application to Early Warning and guards against from the internal security risk. And we unifies the distributed system and the Component technology, designed a information audit system based on the APA. Through Component-based programming method, this system can be extended and reconstruct easily. This system also provides a platform for the development, supporting fast constructs information audit system. Finally, this article in view of the interior application of information system, designed the components: the system environment monitor, the file operation monitor, the system device monitor and the network application monitor.
