Page 11: 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 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.
- Page 13 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.
- Page 14 Security recommendations • Use the authentication and encryption mechanisms of SNMPv3 if possible. Use strong passwords. • Configuration files can be downloaded from the device. Ensure that configuration files are adequately protected. Configuration files can be password protected during download. You enter passwords on the WBM page "System >...
- Page 15 Security recommendations • If a secure alternative is available for a protocol, use it. The following protocols provide secure alternatives: – SNMPv1/v2 → SNMPv3 Check whether use of SNMPv1 is necessary. SNMPv1 is classified as non-secure. Use the option of preventing write access. The product provides you with suitable setting options. If SNMP is enabled, change the community names.
