Centralized Document Storage:

• Any decent document management system ( DMS ), whether it is open source or commercial, will allow documents to be stored in some sort of centralized location.

Limited Access:

• Having a centralized location to store files is not enough to call your product a document management system. 
•  simple folder on your computer can allow files to be stored, but limiting access to specific individuals becomes more of a problem. 

Tracking Changes:

• Limiting access to the DMS files is a good step in the right direction but does no good if the files can be changed, added, removed without tracking of those actions.

Document Management Security

• Secure URL feature to obfuscate URL parameters
• Fine grained user access control for each file
• Departmental access control for each file
