Recommendations on network security

To prevent unauthorized access, note the following security recommendations.
General
• You should make regular checks to make sure that the device meets these recommendations
and/or other security guidelines.
• Evaluate your plant as a whole in terms of security. Use a cell protection concept with suitable
products.
• When the internal and external network are disconnected, an attacker cannot access internal
data from the outside. Therefore operate the device only within a protected network area.
• For communication via non-secure networks use additional devices with VPN functionality to
encrypt and authenticate the communication.
