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.

Context Identity

The idea of context is both easy and hard at the same time. In human interaction, context often eludes transference. The same sentence may be said in the same way and mean two different things, with the differentiator being the context where the same words are spoken. In some languages, context is constant but in most, context remains a variable concept. In terms of security, the same person may access a resource that is allowed in one context but denied in another.

For example, an employee may be allowed access to company banking software in the office but not from home. A laptop computer may be allowed to access any company system within one country but be restricted to specific systems when traveling outside that specific country. A user may be allowed to access the corporate network from the office they normally work at but not from an office within the company that has a higher or lower security policy. Some systems may be allowed during business hours and...
