This design represents a chapter of the overall SAFE Design Guide. This chapter describes the best practices for securing the network infrastructure itself. This includes setting a security baseline for protecting the control and management planes as well as setting a strong foundation on which more advanced methods and techniques can subsequently be built on. Later in this chapter, each design module is presented with the additional security design elements required to enhance visibility and control and to secure the data plane.
The following are the key areas of baseline security:
