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.

Secure Summary

Included in SASE are many security products as well as SD-WAN, which forms the base for the edge extension of the cloud. Depending on the perspective of the team responsible for procuring, designing, implementing, and operating an SASE Service, the initial services may vary. For effective security, all services must be integrated to allow cross-service validation to maintain an even approach to security and mitigating issues that would have increased the threat level.

Key services in a SASE framework include SD-WAN, a firewall, CASB, a ZTF, and SWG. Additional services such as IAM with Multi-Factor Authentication (MFA) are added out of necessity and must be integrated for effective security. All SASE Services must be integrated to ensure minimum security levels are maintained. All SASE Services must be monitored for both performance and security. Monitoring and telemetry are key inputs for AIOps to interact as needed to ensure policy enforcement.
