Hello world.
Perfoming a cyber security risk assessment, the auditor raised the question how the ACN ports on a PK controller are seperated and protected from the ports used for MODBUS TCP communication to different field devices.
I used to the different DeltaV security handbooks and manuals, I can handle the defence in depth strategy quite well (hopefully), but I haven´t found some kind of description or internal wiring scheme to answer this question.
Any ideas or experiences?
Thanks! Regards, Stefan
