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.

Summary

SASE design mixes SD-WAN, cybersecurity, and DevOps design techniques to create a solution that meets the organization’s needs today by integrating multiple applications, security, and network communications solutions into a cohesive strategic SASE Service.

SD-WAN design focuses on disaggregating data and the control plane to create a secure communication forwarding solution. Cybersecurity design is based on ZTF, in which all resources are blocked by default, and only by correctly meeting the policy requirements is any access permitted by unlocking the resource in a step-by-step fashion. DevOps places the operational support model at the heart of the solution, allowing for real-time updates to software at any time. Blending these models allows for a future-focused solution that is as easy to maintain as possible.

Design theory will continue to evolve. Leveraging a philosophy around DevOps with a grounding in ZTF brings you closer to this. An SDN mechanism to leverage...
