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 Effective

An effective policy is a policy that meets the needs of the organization at the time it is implemented. Unlike a political or fiscal policy, SASE Policy must not trust – however, it must be fluid, dynamic, provide quality, and change as often as needed to continually be effective.

SASE Policy must take a layered approach that is prioritized from most critical to least critical. It must leverage a least prescriptive, open model that allows resilience in the architecture while it’s being used. Conditions change, so the policy must adapt to allow for unplanned conditions.

To design an effective SASE policy, the basic layered approach to security must be used, starting with a closed ZTF-based solution and opening it when all the requirements have been met for secure communications.

In conclusion, an effective SASE policy allows secure communications services to be implemented if the security requirements are continually met.
