Re: [foxboro] Ethernet FBM security

It sounds like as long as the PLC network is stand-alone, and it is
controlling/interfacing with a non-critical process, there isn't much
risk, but if you connect the PLC's to the business LAN or other outside
networks and/or if you cannot tolerate any downtime or dropped
communication between the PLC and the I/A, you should probably put in a
firewall between the PLC network and the FBM.  

Thanks for all the responses.

I did put in a PER with the word security in it

If you browse to an Ethernet FBM you get a blank page stating the web
server is enabled but not implemented which I see as a red rag to a bull
for a hacker.
The PER did go on to suggest the usefulness of putting something on this
page like other vendors but I know the importance of PER's to Foxboro
