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.

Zero Explained

The best way to explain the ZTF is by stating that access to every user, device, system, or system component is locked out by a default policy, and each component is unlocked by meeting the policy requirements for access one at a time. Essentially, if zero trust works correctly, then nothing works unless an explicit policy match is achieved.

It is necessary that the ZTF be aggressive to ensure that an organization is as safe as possible. The ZTF replaces standard firewall concepts by working through all layers of the Open Systems Interconnection (OSI) model. It accounts for what is happening in the world as opposed to what is expected to happen in the world. All security services will leverage the ZTF as the standard going forward.

To explain the effort required for the ZTF is to explain the benefit of uninterrupted execution of an organization’s mission. The ZTF is the method of eliminating the impact of a cyberattack on the organization.

The ZTF is...
