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.

Zero Trust

As an end user, it is convenient to trust your laptop, specific people, and specific software applications. Much of the issues with security for any organization, whether physical or logical, comes from someone trusting. Security issues are often caused by accidents; it’s like leaving a gate open and letting a pet out. With the pet, it may not make sense to do a double gate system, whereby one gate has to be closed to open the other. With technology, we need to employ security far more effectively than two gates; we need both defaults to closed and fails closed.

Sessions in zero trust, once authorized, are trusted until they are terminated. Any new session between a subject and target actors must be reauthorized prior to passing either control or data plane traffic. In the future, life cycle sessions may monitor a session for indications of extraordinary behavior such as gross variations in throughput or quality. The life cycle session would have the ability to...
