BSEE needing CS training

One of our clients is requiring us to complete a vulnerability study as related to asset hardening. I am an electrical & computer engineer and have tried to avoid the world of computer science as much as possible. Don't know why they want an engineer to do this, but, it's my job.

So any info anyone can provide as related to asset hardening of servers, desktops, laptops, PLCs, DCSs, OPC, networks, and general control systems would be of great help.

I am also looking for some sort of chart or diagram that shows all the possible MS certifications and paths, and recommendations of which will help me in my current task.

Any help is appreciated in getting me started.
