Re: [foxboro] Ethernet FBM security

Stupid Crackberry...

We're doing a security assessment at one of our refineries that has 
FBM232/FBM233's, and the question is coming up of what ability is there of 
Ethernet packets to traverse from the PLC network through the FBM to the MESH 
network.  Obviously, the Modbus TCP and ControlLogix, etc, packets make it 
through if you install the correct device driver or it wouldn't work, but what 
about other packets that could constitute malware, DoS, etc?  Is the FBM a 
filter that definitively stops all other packets, or should we be putting a 
firewall between the PLC and the FBM?  I'd be interested to hear what everybody 
is doing or what Invensys considers is best practice.

It must be good.  That encryption is inscrutable :)
