3.7 IP security according to BDEW guidelines (optional)
A white paper with basic security measures for control and telecommunications systems has been
developed for companies in the energy industry. The goal is to adequately protect the systems against
security threats in daily operations. This optional function "IP-Security" serves to fulfill these
requirements. The following functions have been added or extended for this purpose:
Password management
Firewall settings
Certificate management
File transfer via SFTP (Secure File Transfer Protocol)
Communication using HTTPS (Hypertext Transfer Protocol Secure)
For detailed information on the IT security functionalities, please refer to the separate documentation
MSM-SEC-BA-UK.
The individual reporting channels can alternatively be controlled via a galvanic input
or the 61850 interface. Which of these two possibilities is used for each individual
channel can be parameterized. An acknowledgement via the 61850 interface is
possible as well.
