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.

SD-SASE

SD-WAN and SD-SASE are both based on the need for secure network communications. SD-WAN is an existing technology. SD-SASE is redundant nomenclature, as SASE solutions are expected to be SD. The reason for a SD-SASE chapter is to underscore the SD nature of future solutions. SASE is inherently SD on a per-service basis. Integrating SD-WAN with SASE leveraging SD tools and methodologies is the commonsense approach for the near future at least.

The simplistic view is that SD-WAN takes the place of the router at the edge of each network and then connects to other SD-WAN endpoints to securely forward traffic to where the necessary services exist. SASE industry standards incorporate SD-WAN into SASE services as a potential endpoint for secure communications to a physical or logical location.

Moving on to a security perspective, SD-WAN security mechanisms can securely interact with SASE services to increase the overall security posture of an organization. The ZTF and AI-based...
