Zero Trust in the Cloud: Adapting Principles for IaaS, PaaS, and SaaS

Introduction: Securing Beyond the Traditional Perimeter

Welcome back! In our journey through Zero Trust, we’ve established its core principles: Verify Explicitly, Use Least Privileged Access, and Assume Breach. These principles fundamentally challenge traditional perimeter-based security, where everything inside the network was trusted. But what happens when there is no clear network perimeter?

That’s the reality of cloud computing. Organizations are rapidly adopting Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS) models, moving critical applications and data out of on-premises data centers. This shift dissolves the traditional network boundary, making the “trust but verify” model not just inadequate, but dangerous.

Welcome back, future firewall master! In our journey so far, we’ve covered a tremendous amount, from the basic building blocks of Palo Alto Networks firewalls to advanced features like App-ID, User-ID, and SSL decryption. You’ve learned how to configure these powerful tools. Now, it’s time to elevate your skills from just knowing how to do things, to understanding how to do them right in a real-world enterprise environment.
