"Swiss Army Knife" for safety systems - is it a feature or a vulnerability
On Tuesday, a major control and safety system vendor held a webinar on cyber security of safety systems - "The rocky relationship between safety and security". The vendor talked about the network issues that needed to be considered, limitations on read/write, etc. However, the diagram that was shown on the webinar had the control and safety systems on the same Ethernet LAN. I talked to the vendor about it. His response was their design was like a "Swiss Army Knife" (a feature).
