Looking for ICS/SCADA security training

Hi all,

I'm looking for some references or resources that are more technical and in depth for industrial control or infrastructure security. I've reviewed some of the materials from Idaho Labs, and would like to take the SANS GICSP in the future if I can get an employer to cover it, but I am hoping to expand my options to stuff that's not hands on and affordable. This seems to be one of those fields that's hard to get into …
