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.

SASE Flow

A SASE session flow is a decision-making matrix that allows packets to flow across the secure network connection in the SASE session. If an answer isn’t provided for any of the interrogation process decisions, the packet is blocked and the session is ended. When the session is terminated, the authentication process is required for the next session, which ensures security measures are not violated.

MEF 70.1 defines an Application Flow Specification (AFS) as “A named set of application flow criteria.” The AFS is a key attribute for the SASE service to use in determining specific application behaviors. Via pre-identification, the SASE service creates an understanding of any predicted behavior that may be analyzed in flight to understand when non-predicted behavior occurs. Non-standard or non-predicted behavior triggers a security response to terminate bad actor communications. By terminating the session, good actor communication may reestablish communications...
