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 Session

According to the MEF Forum, “A SASE session, or session, is the ephemeral flow of IP packets between two actors.

The SASE session starts when one actor attempts to communicate across the network with another actor. Before establishing an active session, the authentication process must be completed. No data plane communications will occur without valid authentication to create a secure session.

The SASE Managed Service Provider (MSP) is responsible for managing the overall service to ensure no communications take place without all the security requirements being satisfied. When a secure session is established, the mission also includes quality monitoring to ensure all the communications meet the Service-Level Agreements (SLAs) that have been contracted for the subscriber.

In the process of building a session, the following steps occur:

  1. The session receives a unique session ID
  2. The session ID must be unique within the service
  3. The SASE...
