The "SAFE: Extending the Security Blueprint to Small, Midsize, and Remote-User Networks" (SAFE SMR) blueprint was written approximately one year after the successful release of "SAFE: A Security Blueprint for Enterprise Networks" (SAFE Enterprise). The SAFE SMR blueprint provides best practice information about designing and securing networks that are of a smaller scale than that described in the original SAFE Enterprise white paper. SAFE SMR uses the same principles as the original SAFE Enterprise white paper and scales them appropriately for smaller networks. These smaller networks can be branches of larger, enterprise networks or standalone small to medium-sized deployments. SAFE SMR also covers other deployment designs, such as telecommuters and mobile workers.
The general design of the SAFE SMR includes two core modules:
The Campus module
The Corporate Internet module
The small and medium-sized network designs both use these two modules. The medium-sized network design goes further to cover additional WAN modules that are not included in the small network design.
