This chapter is devoted to the practical concerns associated with implementing an enterprise-wide, holistic solution. The aim is to demonstrate how operational assurance of the organizational threat space is maintained as a dynamic system as the situation evolves. Implementation is the second formal stage in the overall process of developing a practical, strategic, holistic control solution. Hence, this chapter presents and discusses the practical principles and methods required to create a functioning, real-world, holistic governance architecture. The outcome of this phase is a standard, fully documented, holistic security solution that incorporates all relevant security best practices. These practices are then maintained in day-to-day operations by a tangible, comprehensive infrastructure of well-defined management actions, specifically designed to optimize the effectiveness of the security solution.
