The Building Phase
The personnel responsible for building the security design are not usually the same people who were involved in the planning stage. In the building phase, experienced network administrators, security specialists and consultants will use the available hardware and software to create the security that the security design team has envisioned.
The administrators will create, deploy and test security templates and policies. This is usually done in a testing lab to assess the impact of security decisions before placing them into a production environment. After testing has been completed, the templates should be rolled out in phases. A test group can be used to ensure that nothing has been missed in the lab before rolling the security out to the whole network. A thorough knowledge of what is available and how it relates to network security is the key component in the building phase.
