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.

Forward Concept

Going forward, the concept for SASE is to secure all communications from any device, system, application, or user to any other device, system application, or user by leveraging active, automated, autonomous, and aggressive security solutions.

SASE is expected to be the secure-communications replacement for legacy routers, firewalls, and VPN solutions. It accounts for all available input mechanisms for analysis. SASE is based on an ZTF, which requires a change in thought process for all technology professionals everywhere.

A forward concept is an idea in which we leverage fully integrated services to achieve policy-based goals for our organizations. This can be accomplished by leveraging many systems that are in production today. However, any system that cannot accommodate a ZTF must be eliminated from a production environment quickly.

The market has asked for consideration of parallel environments or hybrid ZTF and legacy security models. There is no benefit...
