This chapter introduces the module construct of the "SAFE: Extending the Security Blueprint to Small, Midsize, and Remote-User Networks" blueprint. In general, a network that is based on the SAFE design principles tries to follow a modular concept when dividing out network functions. It is not required that the design adhere strictly to the SAFE blueprint; however, it is important to realize that the security benefits of SAFE are derived from these blueprints and can be realized only if the network design meets the blueprint recommendations.
