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.

SASE Dynamic

Prescriptive policies choke resiliency within the SASE Service and create work for operations teams and administrators. Service resiliency requires the ability to act based on real-time conditions or changes to the operating environment. A policy must provide options for the secret sauce of the service to restore secure communications as needed. In the past, policy-based routing was designed for perfect conditions.

When a less than perfect condition arose, such as a faulty circuit causing a brownout, where it would work intermittently but not effectively, the network operations team would have to troubleshoot the issue and find a solution. With most SD-WAN solutions, the service will move the session around the brownout circuit and trigger a notification. The notification may then be passed to the service management system, which then creates an incident in both the carrier’s system and the host organization’s system.

The system can be augmented...
