#### Synchronization of the security cache system

A synchronization system has been provided for synchronizing JReport Enterprise Server's security system with your external security systems. When the security cache system receives a security information modification event, it will then fetch the security information from the API and update the cached information.

The following is a diagram of the synchronization system mechanism:

There are two ways to invoke the synchronization system. The first is to modify the security information on our Server web UI (red line), and the second is to modify the external security system (blue line).
