ABSTRACT
The conceptual security architecture is where the security architect really starts to add value. At this stage you have gathered and analysed all the necessary information about the business of the organisation. What is needed now is a vision of the future – a conceptualisation of the types of solution that will satisfy the business needs. If you get this part right, then everything else should flow with ease. If you get this part wrong, nothing at the lower layers of the architecture will ever fix it. This chapter describes some of the key areas where you will need to apply your conceptual creativity.
