Diving into Secure Access Service Edge

Overview of this book

The SASE concept was coined by Gartner after seeing a pattern emerge in cloud and SD-WAN projects where full security integration was needed. The market behavior lately has sparked something like a "space race" for all technology manufacturers and cloud service providers to offer a "SASE" solution. The current training available in the market is minimal and manufacturer-oriented, with new services being released every few weeks. Professional architects and engineers trying to implement SASE need to take a manufacturer-neutral approach. This guide provides a foundation for understanding SASE, but it also has a lasting impact because it not only addresses the problems that existed at the time of publication, but also provides a continual learning approach to successfully lead in a market that evolves every few weeks. Technology teams need a tool that provides a model to keep up with new information as it becomes available and stay ahead of market hype. With this book, you’ll learn about crucial models for SASE success in designing, building, deploying, and supporting operations to ensure the most positive user experience (UX). In addition to SASE, you’ll gain insight into SD-WAN design, DevOps, zero trust, and next-generation technical education methods.

Service Flight

An aircraft in flight is designed to embody the beauty of a bird in flight. The grace by which both birds (naturally) and aircraft (by way of technology) glide through the air has a freeing effect on the imagination. A SASE service in flight should have a similar flight effect to an aircraft but also incorporate how birds can fly without the need to use technology.

To set up the conditions for our flight, we will start in the desert with a single user and a single device that needs to access an emergency service. This device has power but no connectivity. To access the device, the user must authenticate locally on the device, so they will need an access code and a biometric identifier. Two methods become the entry level and a single method does not allow access. This can be secured by a third local identification method, but the fact that the user has the device also counts as a third identification component. At this point, the user has access to the device.
