When the internal and external network are disconnected, an attacker cannot access
internal data from the outside. Therefore operate the device only within a protected
network area.
•
No product liability will be accepted for operation in a non-secure infrastructure.
•
Use VPN to encrypt and authenticate communication from and to the devices.
•
For data transmission via a non-secure network, use an encrypted VPN tunnel (IPsec,
OpenVPN).
•
Separate connections correctly (WBM, SSH etc.).
•
Check the user documentation of other Siemens products that are used together with
the device for additional security recommendations.
•
Using remote logging, ensure that the system protocols are forwarded to a central
logging server. Make sure that the server is within the protected network and check
the protocols regularly for potential security violations or vulnerabilities.
