Security Convergence: Managing Enterprise Security Risk

By Dave Tyson; Reviewed by Karim H. Vellani, CPP, CSC

***** Security Convergence: Managing Enterprise Security Risk. By Dave Tyson; published by Elsevier/Butterworth-Heinemann; available from ASIS, item #1745, 703/519-6200 (phone), www.asisonline.org (Web); 232 pages; $45 (ASIS members), $50 (nonmembers).

Reading this work will be an eye-opener for security professionals unfamiliar with the parallels between the dual disciplines of physical and logical security. Using practical examples, Tyson pinpoints where the two industries are today, where they are going, and more importantly, what physical security professionals must do to prepare for the day when those once “parallel” lines converge to form true enterprise security. 

Security Convergence wisely begins by defining convergence and identifying what it means for physical security professionals. The book then tackles what may be the greatest challenge in developing an enterprise security management department: the cultural differences. Rather than focusing only on the differences, however, Tyson also identifies the similarities between physical and logical security departments, including the similarities in their tactics and in the threats that they help organizations face.

Later, Tyson discusses the technological advances that have shaped the physical security industry, how those advances are pushing convergence, and the benefits, such as shared resources and streamlined security department hierarchies. Several chapters explain how physical security professionals can educate themselves on the evolution of security.

Security Convergence then provides a blueprint for organizations to follow in developing or refining an enterprise security department, including gaining senior management buy-in and inventorying skills and assets. The book explains the transformation organizations of various sizes must undergo to achieve real enterprise security. Most critically, the book makes the business case for security convergence and explains the impact on each department of an organization.

From start to finish, Tyson makes a convincing case for convergence and prepares readers for what is to come. This book is among the first on this topic, and Tyson has set a high bar for authors who follow. It should be required reading for most security professionals and especially for those senior security managers and directors who are continuing their quest up the corporate ladder.
