  • Page 11: Recommendations On Network Security

    Industrial Security (https://www.siemens.com/ industrialsecurity) website. ● Inform yourself regularly about security recommendations published by Siemens ProductCERT (https://www.siemens.com/cert/en/cert-security-advisories.htm). ● Only activate protocols that you require to use the device. ● Restrict access to the management of the device with rules in an access control list (ACL).
  • Page 12 Recommendations on network security ● The option of VLAN structuring provides protection against DoS attacks and unauthorized access. Check whether this is practical or useful in your environment. ● Use a central logging server to log changes and accesses. Operate your logging server within the protected network area and check the logging information regularly.
  • Page 13 Recommendations on network security Secure/non-secure protocols ● Avoid or disable non-secure protocols, for example Telnet and TFTP. For historical reasons, these protocols are available, however not intended for secure applications. Use non- secure protocols on the device with caution. ● Check whether use of the following protocols and services is necessary: –...

  • Page 65: Appendix

    Appendix EMC-compatible installation of electrical Industrial Ethernet or PROFIBUS cabling The Industrial Ethernet / PROFINET system manual "Passive network components" prescribes the use of fiber-optic cables for cabling between buildings and/or external facilities because there may be large potential differences between nodes. If IE FC or PROFIBUS FC cables are used for such applications, the same rules apply as when installing cables indoors.
  • Page 66 Appendix A.2 Equipotential bonding When and why is equipotential bonding necessary? Several good reasons for equipotential bonding are listed below: ● Devices with a grounded interface can be damaged by potential differences. ● The shield of the PROFIBUS cable must not be used for equipotential bonding. This is, however, the case if parts of the system connected by the cable shield are connected to different grounding points.
  • Page 67 Appendix A.2 Equipotential bonding In systems in which no equipotential bonding is possible, the current flow via the shield needs to be prevented. Despite this, to be able to use the shield properties of the cable note the following: ● Contact the shield at one end with low resistance. ●...
