A.5
Certificates for the secure data transfer
A.5.1
Overview
The "Transport Layer Security" (TLS) protocol enables encrypted data transfer between a client
and the SINAMICS drive. HTTPS access of the browser to the drive is based on the "Transport
Layer Security" protocol. This section informs you which steps you need to follow to enable
encrypted data transfer between a browser (client) and the SINAMICS (server).
You will find information on the configuration or your IP connection in Section:
"Configuring the IP connection (Page 158)" .
Protecting the HTTPS access
The encrypted variant of the communication between the browser and the Web server using
HTTPS requires the creation and installation of certificates.
Basically, there are three ways of creating a server certificate:
● Use the default configuration
● Use self-created certificates (by means of certificate software, such as OpenSSL)
● Use a server certificate from a certificate authority
You can only use the default configuration for SINAMICS S210, firmware version 5.1.
Delivery state
A private key is generated as a file on the device as default configuration when you first use
HTTPS so that you can access the drive via HTTPS in the SINAMICS delivery state. During
an HTTPS access using this key, a warning is issued in the browser that the certificate is
unknown.
Duration of validity
The certificates are valid up to 2030.
After expiration of the validity period, install new valid certificates on all the relevant drives.
A.5.2
Using the certificate default configuration
Note
Security
The use of a default configuration described in the following is not the most secure way of
transferring data using the HTTPS protocol to your drive with the Web server.
For this reason, it should only be used in secure networks (e.g. your PROFINET below a PLC)
or for direct point-to-point connections on the Service interface X127.
