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

A SASE Session is the core function of any SASE solution. Connecting the target actor to the subject actor, regardless of the connection type, in a secure session, based on identity and context, is why SASE exists. The SASE session must be established correctly and any violations or gaps in the policy will prevent any new session from being established. Any violation of the policy, while a session is active, will result in the session being terminated. In the future, the life cycle session will police sessions in motion for active security, as well as heal session performance without terminating the session. At the time of writing, the Zero Trust Framework (ZTF) ensures no session is established if it doesn’t meet all the criteria for secure communications. The User Network Interface (UNI) provides a service inspection and monitoring point, as well as various services. The SASE Application Flow Specification serves as an enhancement for understanding behavior on...
