Appendix A. SAFE Blueprint
Cisco has developed a design guideline called the SAFE blueprint. This appendix introduces the SAFE blueprint and supplies an overview of its architecture. Much of the material in this appendix is quoted directly from the relevant websites that are listed at the end of the appendix.The principle goal of the Cisco secure blueprint is to provide best-practice information to interested parties on designing and implementing secure networks. This blueprint serves as a guide to network designers considering the security requirements of their networks because it takes a defense-in-depth approach to network security design. This methodology focuses on expected threats and methods for mitigating them. With SAFE's layered approach to security, the failure of one security system is not likely to lead to the compromise of network resources.
