Permissions required for data import

Following are the required entities permission to allow a user to import data into crm through data import wizard.

 - Data Import (all)
 - Data Map (all)
 - Import Source File (all)
 - Web Wizard (all)
 - Web Wizard Access Privilege (all)
 - Wizard Page (all)

 - Entity privilege which user needs to import data for.

I am not sure if we need all privilege here as I have used some of the entities mentioned above with less privilege and it worked fine.
