Physical and information-security systems have been implemented independently inside many enterprise organizations. This singular view of enterprise-risk management has created gaps and shortfalls within organizational security systems. The purpose of this study was to analyze the barriers, potential benefits, prevalence, and critical success factors associated with security convergence within both U.S. and international enterprises from the perspective of security professionals. The theoretical base for the study is grounded within the risk-intelligence framework and the enterprise risk management risk intelligence capability maturity model. The research questions focused on capturing the perceptions of security professionals with regard to security convergence. A case-study quantitative methodology was employed with a survey sample of 143 participants. The research design utilized the security convergence survey (SCS) instrumentation, which captured Likert scale ratings from a sample of both information and physical-security professionals. ANOVA, t-test, and one way variance analysis of survey data revealed that the main barriers to security convergence are the need for a clear implementation plan and the need for managers with the expertise to handle both physical security and information security. Also, greater security convergence is needed to address the requirements of recent legislation and to create a universal architecture for unified threat management. The data support the need for further academic research toward design and implementation of an architecture for unified threat management. The study promotes positive social change through the development of security strategies to effectively deter financial crime and prevent the loss of human life.
