For me security means two things: it is a set of mechanisms and actions and a state.

In current usgae we equate security with safey. That a state where a
state of safey from a whole gamut of threats has been achieved. 

I current usage we also equate security with a set of actions, processes
and mechanisms designed to achivee and maintain the sate satate.

Risk Assessments, Threat assessments, risk management  and other mechanisms 
that people mention are tools we use to decide how to best deplpy security
mewsaures to achieve an acceptable level ofsafety, given we have limited

Have a good day...
