  • Page 15: Security Recommendations

    • For data transmission via a non-secure network, use an encrypted VPN tunnel (IPsec, OpenVPN). • 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 16 • 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.
  • Page 17 Implementation Information Disclosure Vulnerability (for example, BEAST). • Ensure that the latest firmware version is installed, including all security-related patches. You can find the latest information on security patches for Siemens products at the Industrial Security (https://www.siemens.com/industrialsecurity) or ProductCERT Security Advisories (https://www.siemens.com/cert/en/cert-security-advisories.htm) website.
