Support The Detection Of Abnormal Behavior Physical Access Control System Design And Implementation

Modern physical access control systems (as known as security systems) have been developed for several decades, and they become more and more powerful. But, at the same time, the security administrators start complained that the security system is becomes very complex, and really not easy to be configured and managed. They have to configure lots of items to make the whole system work steady and efficiently. Each time user changes his/her working hours, administrator needs to modify the schedule of the user's authority, if there are lots of users change their schedules, administrator will be very busy. Therefore, to construct a flexible and easy-to-use security system becomes an important mission of security system industry.First, the weakness of the present physical access control system is analyzed while system configuring and managing. Second, it proved the necessity of constructing a physical access control system with anomaly detection support. And it also discussed system architecture and modules in the system based on the analyzing of customers'requirements about functions of the physical access control system, it changed the "reader-schedule" authority to "area-schedule" authority, and simplified the configure operation of security administrator. Additionally, introduced the anomaly detection technology, and discussed how the anomaly detection technology implemented in the physical access control system and worked with other sub-systems. The discussion is focused on these main subsystems:Management Subsystem, Status Monitor Subsystem, Event Log System, Access Control Subsystem, and Anomaly Detection Subsystem.
