To get an idea of what a decent lab environment for Stuxnet research looks like, check out this great presentation from INL and Siemens. You’ll see pictures from the Siemens security lab in Karlsruhe/Germany on page 52 (controller racks are outside of the picture at the cubicle wall to the right), and from the commissioning of a mirror site in Idaho Falls in June 2008 as part of the NSTB on page 60. If you haven’t seen an S7-400 before, there are several in the upper two rack rows. S7-300s can be found in the bottom row.
