Question:

What are the basic components and architecture of Curtain e-locker?

 
 
Answer:There are 3 basic components of Curtain e-locker:
  • Curtain Client
  • Curtain Admin (for the machine having Curtain Admin, we call it Curtain Policy Server)
  • Curtain Server Plug-in

Curtain Client:
When a user accesses Protected server resources (e.g. Protected Share Folder, Protected website, etc), Curtain Client must be installed in the user's workstation. A secure folder (i.e. Local Protected Directory) will be automatically created in user's workstation during installation of Curtain Client.

Curtain Admin:
Curtain Admin is mainly for system administrators to define Curtain control policies centrally. It also stores audit log for management review. In general, only one Curtain Admin is needed in a company.

Curtain Server Plug-in:
The Curtain Server Plug-in should be installed on any server requiring Curtain protection. It receives periodic instructions from the Curtain Admin console on how to safeguard server resources. While optional, installing the plug-in provides an additional layer of security: by default, it blocks access to protected server resources from workstations that do not have the Curtain Client installed.

Example: This company wants to protect share folders of 5 Windows File Servers. Then, they need to install Curtain Server Plug-in on those 5 Windows file servers.

Here is the basic architecture of Curtain e-locker:

P.S.
- Curtain Admin can be installed on a separated machine or one of the File Servers.
- Curtain Admin can be installed on physical machine or virtual machine (VM).
- Administrators can use the function of "Exception" to allow workstation to access protected server resource without Curtain Client installed (FAQ 00183).
