20.3.2 FTP access with TLS, FTPACCS
GUID-9E64EA68-6FA9-4576-B5E9-92E3CC6AA7FD v3
The FTP Client defaults to the best possible security mode when trying to negotiate with TLS.
The automatic negotiation mode acts on configured port number 21 and server features, it tries to
negotiate with explicit TLS via AUTH TLS. If the specified port is any other, it tries to negotiate in a
similar way.
Using FTP without TLS encryption gives the FTP client reduced capabilities. This mode is only for
accessing disturbance recorder data from the IED.
If normal FTP is required to read out disturbance recordings, create a specific
account for this purpose with rights only to do File transfer. The password of this
user will be exposed in clear text on the wire.
