Publisher Summary This chapter describes the evolution and growth of security industry, the comparison of public police and private security, provides avenues toward the path to professionalism, and offers suggestions for pursuing contemporary careers in asset protection. Assets are tangibles or intangibles that have value, and asset protection is concerned with waste, errors and accidents, natural disasters, labor shortages, equipment breakdowns, and fires. Security is protection from those threats that are posed by humans, such as espionage, sabotage, theft, and assault, and is influenced by commerce, war, natural disaster, economic, and cultural changes. The security industry has a rich and varied background, and it can be physical and personnel security. Policing is both public and private, public policing is relatively recent. Police requires extensive pre-employment screening, training, equipment, and health and pension benefits; therefore, those have to be used more judiciously. Protection from terrorism is another major issue in asset protection. Laws are authored in response to social changes and all relate heavily to asset protection. Security services or contract security agencies have played a large role in both public and private protection. Although contract security firms usually offer private investigative services, most firms specialize in one or the other. There are numerous fields of career open to people seeking a challenging and a rewarding career in asset protection, and career opportunities are for those who are adept at sales, client relations, and human resource management (HRM).
