File Transfer allows only authorized users to upload or download files. Furthermore, only accepted devices can interact with the add-on.
Role Based Access Control is only available in the Mender Enterprise plan. See the Mender features page for an overview of all Mender plans and features.
You can apply additional restrictions on which Mender users can access File Transfer using RBAC. It is fully integrated in the Role Based Access Control system of Mender and accessible from the UI.
The mender-connect, obtains device token through DBus API. It is the same token Mender client is using.
File Transfer uses Encrypted WebSocket connections to communicate with the server. The connection to the device is secure, but there are no additional limitations on what file can be transferred or network bandwidth used. In essence, the File Transfer add-on provides a data passing model over a secure websocket between a device, and the caller (may it be th UI, mender-cli or any other API consumer).
File Transfer does not require you to have any open, listening and bound ports on a device. The HTTPS connection gets upgraded to a websocket, and the transaction proceeds transparently from there on. You do not have to alter any other packet filtering rules, as long as you have allowed traffic over HTTPS to the Mender Server.
Audit logs is only available in the Mender Enterprise plan. See the Mender features page for an overview of all Mender plans and features.
Audit logs hold a list of every file transfer event. You can access this information in the Mender UI.
Within the Limits configuration section you can impose additional restrictions of the file transfer requests. Enabling the limits allows you to control basic security implications of a file transfer:
