Security: Personal precautions, private companies

I am aware of the United Nations’ definition of human security. It now embraces wide-ranging sub-concepts – from refugee security to gender security, economic, environmental, food, health, community, cultural,  political and , of course, personal security.

“Security” is now a full-fledged discipline for both scholars and governments who originally concerned themselves primarily with national/state security whereby security meant the preservation of peace and national sovereignty and integrity.
