OpenVPN). • Separate connections correctly (WBM, Telnet, 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.
Page 12
• Verify certificates based on the fingerprint on the server and client side to prevent "man in the middle" attacks. Use a second, secure transmission path for this. • Before sending the device to Siemens for repair, replace the current certificates and keys with temporary disposable certificates and keys, which can be destroyed when the device is returned.
