Diving into Secure Access Service Edge

By: Jeremiah

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 Feed

If the baseline is zero, then value must be added to the solution to achieve desired outcomes. Think of as an equation with an intial zero value; each positive integer applied increases the equation’s final value such as zero plus one equals one. With ZTF on your network, no device, system, or application provides any value since all access to all resources are explicitly denied. Value of the device, system, or application is only achieved by policies allowing approved communications.

The inherent value is security for SASE, but the benefit to an organization is realized through effective communications across all users, resources, and devices, required to enable the organization to serve its purpose. Starting from zero, and then adding the required functionality for success, provides the proper care and feeding for the ZTF to provide its value to the organization.

Effective human intelligence requires information from as many sources as possible in order to...
