Chapter 5. Solution design
In this chapter we describe the business objectives that drive the functional
requirements of the technical solution.
As a best practice, it is typical in a production environment to deploy a new
technology, such as compliance-based Network Admission Control, in phases,
aiming first at the selected test locations or user groups and then extending the
project to the whole network. In addition, in a real-world scenario it is always
necessary to first test any new technology in a dedicated test and development
network before deployment to the production environment. This document
assumes that all such test lab practices are transparently in place, so we discuss
only the fictional production environment.
There are essentially three parts of this deployment scenario. In this chapter we
explore how the functional requirements drive our project design.
Part 1, “Architecture and design” on page 1, is dedicated to the Security
Compliance infrastructure, including server and client setup as well as policy
creation and assignment. The detailed technical implementation of Part 1,
“Architecture and design” on page 1, is described in Chapter 6, “Compliance
subsystem implementation” on page 125.
Part 2, “Customer environment” on page 75, primarily involves adding posture
compliance-based Network Admission Control components (servers and
enforcement points) to the existing infrastructure. The detailed technical
