Issue Description
What are the working way and basic working principle of PSM?
Alarm Information
Handling Process
The working principle of Secospace PSM is:
Administrators through the Secospace PSM management center connected to Secospace PSM server to set the security strategy, can set authority to the whole server level (this authority may affect the entire client), can also according to client group do authority settings (this authority may affect all the client of the group), can also setup according to individual Secospace PSM client.
Administrator can use Secospace PSM management center in internal network (LAN internal), the management center can through the radio get Secospace PSM server’s address and port number. Administrators can also in the external network (WAN) through setting Secospace PSM server's IP address and port number to visit Secospace PSM server.
Secospace PSM client in the console can through the automatic acquiring server IP form to acquire server address information; this function need the network supports UDP broadcast information. If the network internal has many sets of Secospace PSM servers or Secospace PSM server and the client are not in the same broadcast domain, should use static configuring IP form.
The client operating in the system internal, safe and reliable, the managed user can't close Secospace PSM client. Even if the client under certain circumstances can't run, this computer USB storage device will also be forbidden, to ensure that the data is not illegal copy out. If the managed user disconnected network at the beginning, don't let Secospace PSM client connect to the Secospace PSM server, the client will also manage the USB storage device in accordance with the settings.
Root Cause
The working way of Secospace PSM is:
1. First of all, Secospace PSM client through broadcast way to get Secospace PSM server’s address and port number after startup.
2. Then, Secospace PSM client will connect Secospace PSM server to exchange the information.
3. Immediately get all safety strategy information, when a USB storage device inserted the device in which Secospace PSM located, Secospace PSM client will immediately set the corresponding authority to the current inserted storage device, at this time the USB storage devices will work in accordance with the behavior set by safety instruction.
