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.

Service Options

Many services are marketed as “SASE” but may not lend to an integrated ZTF solution. In this section, we will not qualify each solution but discuss SASE services generically, that is, provide examples that may be included in a SASE solution. It’s the subscriber of the service that must validate that each service integrates, and ultimately ensure an end-to-end secure communications solution.

The following list is of a catalog of services marketed as SASE services with terms and abbreviations. Many services have been defined or discussed in this book:

  • SD-WAN – Software-Defined Wide Area Network
  • CASB – Cloud Access Security Broker
  • SWG – Secure Web Gateway
  • FWaaS – Firewall as a service
  • NGFW – Next-Generation Firewall
  • ZTNA – Zero-Trust Network Access
  • IAM – Identity and Access Management
  • MFA – Multifactor Authentication
  • DLP – Data Loss Prevention
