hello to all , new to RE

[dd85]

i am new to this forum ;i worked in differents fields(including refrigeration and air conditioning )

now I plan to go back to college/university for a degree in security engineering /management .( courses in france and by distance learning in USA or UK )

i know it will sound odd to some of you but i see the security field as an assembly of various
domaines and as a "prospective manager" i think you have to understand all the parties involved in your job .

A+
