摘　　要：文件安全访问控制,是银行自动柜员机安全的核心部分。采用微过滤模型的文件监控系统,将用户、进程和访问控制权限结合,实时监控文件,实现文件安全访问。同时,基于互斥锁的日志文件的操作,实现日志事件生成和写入日志文件的同步,提高了写日志的效率。该文件监控系统,增强了文件的安全性,提高了系统的稳定性。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.
