Cloud Security by Design: Architecture and Threat Modeling

Building secure cloud environments requires shifting security to the very beginning of the design phase rather than treating it as an afterthought. This text-based course guides you through the core principles of security by design, helping you build resilient architectures on major cloud platforms. You will transition from basic cloud concepts to designing defense-in-depth strategies, managing modern identity and access controls, and incorporating automated security checks. By understanding how to threat model your infrastructure early, you will protect your cloud applications against modern vulnerabilities before they ever reach production. What you'll learn: Understand foundational cloud security principles and the shared responsibility model; Apply threat modeling methodologies to identify potential system vulnerabilities early; Design secure multi-cloud architectures across AWS, Azure, and GCP; Implement zero-trust network security patterns and modern identity management; Configure secure defaults and infrastructure-as-code compliance checks; Practice evaluating real-world architectures through step-by-step written scenarios. The course begins with essential terminology, basic risk concepts, and foundational security models. You will then progress through structured text lessons and practical architectural walkthroughs that teach you how to analyze, design, and secure complex cloud deployments. This course is designed for aspiring cloud architects, system administrators, and developers who want a solid foundation in cloud security, with no prior security experience required.
