Management Plane Security
The MP provides a means for running networks in an orderly fashion. As network devices host increasingly advanced services, the MP is used to help define and operate these services. This plan often requires that the MP store sensitive data, such as service-level agreements, accounting/billing/performance, and other complex service details. Securing all parts of the MP is now less of a choice and more of a necessity, particularly as more network attacks are occurring. The provision of planes greatly facilitates network operations.
In part 2 of this series, we'll look at the details of MP security.
