Software-Defined Perimeter

Earlier in the book, Chapter 9, Edge Routing and Networking, the concepts of software-defined networks and overlay networks were discussed. Overlay networks and their ability to create microsegments is extremely powerful especially in mass IoT scaling and situations where a DDoS attack can be mitigated. An additional component of software-defined networking is called Software-Defined Perimeter (SDP) and is worth a discussion in terms of the overall security picture.

SDP architecture

An SDP is an approach to network and communication security where no trust model exists. It is based on the Defense Information Systems Agency (DISA)'s black cloud. Black cloud means information is shared on a need-to-know basis. An SDP can mitigate attacks such as DDoS, MITM, zero-day exploits, and server scanning, among others. Along with providing an overlay and micro-segmentation for each attached device, the perimeter creates an invitation-only (identity...
