Summary
In this chapter, we looked at SASE sessions, alongside UNIs, actors, the session flow, and the SASE life cycle. The SASE Session is the lifeblood of the SASE Service; without it, no communications can take place in SASE. Many of the service components in the SASE Service exist to ensure no session is established without every individual component matching the requirements. In other words, each service component serves as a key to unlock another lock that prevents the service from working in a less than secure fashion. Once all the locks have been unlocked, the SASE Service functions as intended with great precision.
In the next chapter, Chapter 8, SASE Policy, we will explain the policy components of the SASE Service while covering SASE Policy, SASE Quality, SASE Dynamic, SASE Trust, and SASE Effective. The Policy is the key to all the factors in terms of security, quality, performance, resilience, path selection, and almost every control plane decision.
