Design And Implementation Of Syslog Subsystem In Gateway System Based On Berkeley Database

Nowadays, Internet develops each passing day. As the gateway of network border security protection, needed to deal with security incidents gradually increased, simply log information not meet the requirements. Logs records the system running state, invasion events, configuration audit and other key information, systems, security and efficient treatment is urgently needed. Gateway syslog system appears to solve this problem, through its modular division of work, each function becomes clear. Using Berkeley database stable storage log information, and through a series of log database library interface encapsulation, urgently needed of gateway syslog audit finally be achieved.In this article the author completed the following major tasks:(1) Detailed requirements analysis of the syslog system function. Through the study of related technology author collects user requirements for functionality, role-function analysis and planning system.(2) Functional classification of syslog system in user space and kernel space. The overall architecture design and database design.(3) Specific code implementation of syslog system each function and construction of SMTP client. Log local display, report file generation and syslog system commands configuration, save and restore.(4) Functional self testing of the syslog system. Test coverage to be achieved for all functions.Syslog system has recently passed a new version of the gateway devices to market, which is functioning properly, responsing and handling in a shorter time, working for a long time and having a good user experience. Receive customer feedback, compared to the previous version can be high maneuverability, increased audit approach, high reliability, finally achieved the desired objectives of syslog system.
