Some very concerned friends you have, wanting you to up date your cv. 
i assume SC is secret crypto?
i don't know ANY of those programs, where would you get them?

hi lucy,
The first thing you will need is exposure, to computers in general,
then you need a sound knowledge of networking.
and you have to be dedicated, really dedicated and patient.
if you feel you meet all these, look into these courses.
