WARNING
Network security risks due to improper firewall configuration
Improper firewall configuration may cause network security risks, for example, data leakage, virus invasion, and hacker
attack. This may lead to incorrect parameterization or machine malfunction, which in turn can result in death, severe
injuries and/or property damage.
Do not use the control system inside a network infrastructure without an additional security product.

Make sure that you disable the unnecessary ports in the firewall configuration.

Note
After you disable a communication port, the existing connection established earlier via this port will not be disabled until you
manually disconnect it or the control system restarts/powers off. Therefore, it is recommended that you disconnect the
established connections or restart the control system after disabling the ports.
