A document management system configured to manage an access to a file includes a selection unit configured to select a virtual security policy for setting on the file, which is previously provided for each device, an acquisition unit configured to acquire access authority information for defining an authority for accessing the file based on the virtual security policy selected by the selection unit and authentication information about a user who has set the virtual security policy, a conversion unit configured to convert the virtual security policy into a real security policy that can be commonly interpreted by the document management system based on the access authority information acquired by the acquisition unit, and a management unit configured to set the real security policy converted by the conversion unit on the file to manage an access to the file.
