[Cloud storage] Dropbox Business concept of folder permissions [File server]

This is Ohara from the technical sales department.

With the spread and expansion of remote work,
the introduction and use of cloud storage (cloud file servers) is also increasing.

However, since most of these cloud services are used by company operations and teams,
it is necessary to carefully design folder permissions and security before using the service.

This time, we will describe the roles and permissions of folders assuming the use of Dropbox Business

Dropbox folder types

kinds Features access rights Purpose
● Personal folder ・Basics of Dropbox folders ・Individual only ・Replacement of user folder of file server
● Shared folder ・Users can optionally invite other users and use it as a shared folder
・Personal folders can be changed to shared folders
- Two types of permissions can be set: owner is user
, and editable/viewable.
- Unique access permissions cannot be set for subfolders within a shared folder.
・Use this when you want to share a project folder for a limited time.
● Team folder ・Only administrators can create
・Permissions such as sharing range can be set for each folder
- Two types of permissions can be set: the owner is an administrator
, and editable/view only.
- Users/groups can be added to subfolders and used as shared folders.
- Access rights of the top-level team folder are inherited
. It is also possible to reduce access rights
Use when you want to share information while managing access rights on a department-by-department basis.
・It is the main destination for migrating shared folders on file servers.

Difference between "shared folder" and "team folder"

■ Shared folder

- You cannot create a shared folder with different permissions under a shared folder.
・Top-level permissions are always inherited by subfolders.

■ Team folder

- You can create a shared folder with different permissions under the team folder.
・Superordinate permissions are inherited by subfolders.
- It is possible to add and delete access rights.

Roles and permissions in the Dropbox folder

role authority
● Owner ・You can change viewing/editing permissions, invite members, and change the owner to another person.

・Initial role of the creator when creating a shared folder

● Editor (editable) ・You can add/edit/delete files in the folder just like the owner.

・If the owner allows it, you can invite/delete other users to the folder and change their roles.

・Initial value when an editor is invited to a folder

● Viewer (can view) - Adding/editing/deleting files in the folder is prohibited.

- Viewers can see that they can only view the folder by putting a lock mark on the folder icon.

How to limit browser sessions on devices

it is not possible to limit devices or IP addresses.
If you want to control browser login, you need one of the following methods.


Periodically run a script that displays a list of active web sessions and

② Check the IP address during single sign-on.

③ Use an SSO product that supports certificates, etc.
