This book stems in the main from papers presented at the Third CAMIS Security Management Conference, which was held at Birkbeck College, University of London, in September 2007. The varied but integrated body of knowledge covers national security, corporate security, intelligence work, and disaster/emergency management and planning. A range of perspectives, disciplines, approaches and styles are evident in the work and many intellectually challenging topics, and issues are included for discussion. The work will be of interest to a wide and diverse audience, indeed, it will appeal to senior managers, security and intelligence experts, law enforcement personnel, disaster and emergency management practitioners, as well as policy makers and their advisors, and academics and university students. The arguments entered into, the conclusions drawn and the recommendations offered, should stimulate interest into the complex and evolving body of security knowledge. The insights produced will add to the theory building process and stimulate a wider interest in the subject. In order to deal effectively with future security challenges, governments will need to devise and implement effective counter-terrorism strategies. This means that policy makers will focus attention on the linkages between national security frameworks and security sector reform, and 'value-based' strategic planning. By understanding and broadening their knowledge of resilience, it should be possible for managers to devise a security architecture that embraces disaster and emergency management policies and practices. As a consequence, the knowledge and expertise acquired will be taken into areas such as security relating to major sporting events and this should ensure that the concept of security is placed in a wider and more strategic context than is the case at present.
