Morphology

security = secure (transparent) = secure + ity

Formation is a standard adjective-to-noun derivation ('secure' + '-ity') meaning 'the state or condition of being secure', which directly yields the senses of protection and safety.

Etymology

Security comes from the Latin word securus, which means 'without care', and it is the same root as secure and sure; think of guards, alarms, or locks making a place 'without care' by keeping danger away. So security (the devices or people) protects things and makes them safe.
