26. Cyber security
The relay supports role based user authentication
and authorization. It can store 2048 audit trail
events to a nonvolatile memory. The non-volatile
memory is based on a memory type which does not
need battery backup or regular component ex-
change to maintain the memory storage. FTP and
Web HMI use TLS encryption with a minimum of 128
bit key length protecting the data in transit. In this
case the used communication protocols are FTPS
and HTTPS. All rear communication ports and op-
tional protocol services can be deactivated accord-
ing to the required system setup.
