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 Automation

Initial automation of SASE Services can be visualized as AIOps, but the groundwork for the automation must be laid in the form of modular components that may be observed, triggered, operated, and acted upon by the AIOps solution.

A least prescriptive design must be performed, whereby policy is based on loose requirements through small, simple policies. The small simple policies are initially parallel and can be organized hierarchically, from the greatest common denominator to the least common denominator. Each policy should have the ability to stand alone as a module for the AIOps solution to trigger as needed. An Intrusion Detection System (IDS) detects security threats. An Intrusion Prevention System (IPS) triggers predetermined reactions to individual threats. AIOps operates on the same principle but cannot be effective with prescriptive reactions to threats. Instead of prescription, a library or catalog of small, singular actions must be created to provide...
