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.

Services Core

From a market perspective, SASE is a secure communications service that solves many of the existing issues with legacy systems. In reality, SASE is a collection of services that each performs an important vertical function, but the value of SASE is when these services are integrated into a single cohesive SASE service.

The core services were initially defined as SD-WAN, CASB, SWG, FWaaS, and ZTNA, as follows:

  • SD-WAN is the software-defined secure data forwarding through an encrypted tunnel service.
  • CASB is the manager of cloud application security for both access and data loss prevention.
  • SWG is the tool that ensures only secure access is used between users and the internet.
  • FWaaS is essentially a cloud-based firewall that can be used for both legacy and next-generation firewall capabilities.
  • ZTNA is the access tool that provides next-generation capabilities and removes legacy issues from previous remote access tools, such as client access VPN...
