ABSTRACT

This chapter is an introduction to the world of security, for the ordinary person as well as the trained experienced professional. Coincidental with man’s progress through the ages of time, the basic need and desire for security led to the development of weapons from rocks and sticks to bows and arrows and the invention of gunpowder and guns, bombs, and atomic destruction. The search has always been to develop new means of warfare, better ways to conquer foes. Mirroring the effort to invent and develop bigger weapons, the race to develop security, protection, and safeguards against those weapons followed in a timely manner. The term “security” means many things; thus, the many faces of security. The common defining term of security is that it represents a barrier between the vulnerable person/place or thing being protected and those that would encroach against it.
