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.

Secure Overview

The reason that SASE was coined was due to repeated attempts by large organizations to ensure effective security through diverse product portfolios. SASE is the intersection of secure SD-WAN, application security, cloud security, network security, remote access security, data security, and identity security. Secure Access Service Edge provides a framework approach to many different security solutions on the market. Effective security starts with a layered approach, such as a castle, wall, and moat. A ZTF allows a completely blocked resource to become available, as each layer of security is unlocked by meeting each policy requirement for access at that layer.

For the DevOps team, SASE starts with a Cloud Access Security Broker (CASB), Web Application Firewall (WAF), or Secure Web Gateway (SWG). Often, the application development team acquires these solutions outside of procurement processes as part of a cloud platform marketplace offering. Many times, the purchase...
