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.

Summary

In this chapter, we talked about the SASE service, its working definition, components, roles, and requirements, and then visualized the service in flight. A SASE service is simply a secure communications service. That service may be from a single branded software or hardware manufacturer or may be composed of multiple services from separate providers. The components of a SASE service include IAM, AAC, PEP, and EPC. This list of components will continue to evolve but this model helps us understand the various roles, which are subject to change each time a request for communication is initiated. Any endpoint can be in multiple roles at any given time, whereas each role requires separate security authentication and may be subject to multiple policies. The requirement for a SASE service is a least-privilege web of security policies and services. This web allows any service to restrict access, ensuring nothing slips through a gap. SASE services are complex, with constant updates...
