EMP hardening

How do you EMP harden a computer



Put a high-grequency choke filter on the power line and shield the box. If the box is metal it is probably pretty well shielded already.


This applies to high altitude generated EMP (HEMP), which is what most people mean by EMP. HEMP is noy nearly as threatening as it is usually portrayed in the popular press. Protection for many devices is quite easy. I once carried a very cheap calculator (free) in a pocket and accidently subjected it to a full threat-level EMP pulse, with no adverse effect at all.


If you are talking about source-region EMP or system-generated EMP (SGEMP) then it is much harder and you are probably out of luck.
