Link Permissions SHOULD Be Set to Enabled Anyone Links to View
Description
The Anyone links default to allow people to edit files, as well as edit and view files and upload new files to folders. To allow unauthenticated sharing but keep unauthenticated people from modifying the agency's content, consider setting the file and folder permissions to View.
Policy
Anyone link permissions SHOULD be limited to View.
Licensing Considerations
