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.

Stakeholders Overview

Why are stakeholders so important to SASE? The simple answer is that SASE policies are used for secure communications to devices, applications, and resources for each user within an organization starting with ZTF. No access from any user or device to any application, system, or network of any kind is the default. For access, a policy must be created that allows it. Effective security comes at the price of conscious effort.

ZTF is not like traditional configuration or blacklist firewall functionality. Zero Trust equals Zero Access until the policy allows access. This is not an intuitive thought process. ZTF is the right solution but is like having individual locks on everything in the pantry. Your fingerprint might open everything except someone else’s special treat that only works with their fingerprint.

Zero is the starting point in the journey and each organization can define its journey but requires input from key stakeholders as to what should...
