Indeed, the likelihood of occurrence of the threat posing the risk will determine the need for intervention in the activities within a facility. In other words , Security may be considered assured freedom from poverty or want, precautions taken to ensure against theft, espionage, or a person or thing that secures or guarantees . According to Fischer and Green, (2004, p. 21) "security implies a stable, relatively predictable environment in which an individual or group may pursue its ends without disruption or harm and without fear of such disturbance or injury."
These are the primary reasons underlying the widening horizons and increasing scope of security industry. The security requires manifold diversification of deployment of man power. Thus, the security industry is a diverse and a specialty industry that has a requirement for both generic and domain specific skills (Hesse & Smith, 2001; Manunta, 1996) and being a relatively young and emerging discipline, continues to expand (Fischer & Green, 2004). However, this expansion has resulted in limited tertiary education programs and research to determine the knowledge structure of security.
Security in a wider sense applied to a polity may be expanded to consider national security and the defence of a nation which is managed and secured through use of force and control by armed forces. The power to control is exercised through laws to control a state's citizens and aliens. Security necessarily implies policing of public which includes citizens and aliens with the aid of the armed forces, state police armed with various civil and criminal laws. It is also considered useful in prevention of crime, risk management or loss prevention. This diversity results in a society that has no clear understanding of what security is, but has divergence of interests from many stakeholders.
A traditional definition of security is the provision of private services in the protection of people, information and assets for individual safety or community wellness (Craighead, 2003). Thus more and more business and commercial establishments are bending towards increased security services in preventing undesirable, unauthorized or detrimental loss of an organizations assets. But security may present very different meaning to different people given time, place and context. It has been suggested that security has to have a shared definition among many disciplines, that this is essential and urgent (Manunta, 1996) This is more so in view of the fact that current international fight against terrorism and related threats has given the security a new meaning and dimension encouraging the scholars to study the subject with diverse perspectives, in national, domestic and international fields.
The security to the organization can be studied from two perspectives. Traditionally, the security threat perception of a business organization has been different from security threat perception of a country. However , in recent times this distinction if blurred by the increasing trans-national and multinational activities. The threats to a security is posed by various factors, financial, intellectual property thefts, property thefts, breach of trust, theft of physical property, contractual arrangement with the employees in cases where there is a bar on pilfering the information by them,
