The Cisco Enterprise Composite Network Model

Cisco has developed a SAFE blueprint, the principle goal of which is to provide best practices information on designing and implementing secure networks. The SAFE architecture uses a modular approach, providing the advantages previously discussed. (The SAFE model is discussed further in Chapter 4.)

The Cisco Enterprise Composite Network Model is the name given to the architecture used by the SAFE blueprint. This model supports larger networks than those designed with only the hierarchical model and clarifies the functional boundaries within the network.

The Enterprise Composite Network Model first divides a network into three functional areas, as illustrated in Figure 1-6.
