I just sent the head of IT an email stating that although we don't use siemens products that this virus can infect some other systems if it were to have variants written to target other PLCs and/or automation devices.
I also mentioned that we have windows NT and windows 2000 running on some systems that are vulnerable to stuxnet and its variants and there are no patches available for these OS's.
I had asked if it would be wise to change user rights on these machine "users" and/or put them on their own subnet to keep them less vulnerable.
The short answer I got is that we have tape backup for our fileserver, and that we don't want to have automation systems on their own subnet right now.
I am quite concerned with this, but again, I am not a network or security expert as I've mentioned previously. It does smell funny to me and I'm not sure what to do about it. Our machines are, for most purposes, mission critical and we can lose serious money if they go down for extended periods.
How does an automation guy who is computer saavy but not a security expert deal with IT on these issues. I really want to work together on tightening security.
