Abstract: File security access control is the core of the bank automatic teller machine security. File monitoring system based on minifilter, combining users and processes to access control rights, real-time monitored files and achieved the file security access. Minifilter model shortened the development time, and was stable and compatible. The log file operation based on mutex lock, achieved the log events generat and the log written synchronization, and improved the log-written efficiency. The file monitoring system enhances the file security and the system stability.
