Episode 54 — Architect Cloud Security Across IaaS, PaaS, and SaaS Responsibility Boundaries
This episode explains how cloud responsibility boundaries shape architecture decisions, which is central to ISSAP because many exam items hinge on knowing what the provider secures, what you must secure, and how to prove it. You’ll compare IaaS, PaaS, and SaaS through the lens of control ownership, visibility, and configuration risk, then learn how to design consistent outcomes for identity, logging, network exposure, data protection, and change control across all three. We’ll cover practical patterns like strong tenant-level governance, least privilege for cloud IAM, secure defaults with policy-as-code, and centralized monitoring that captures control-plane and workload signals without gaps. Troubleshooting topics include assuming a service is “secure by default” when key controls are optional, missing logs because they were never enabled or routed, over-permissive roles created for convenience, and SaaS integrations that quietly expand data sharing beyond the organization’s intended boundaries.
