You will learn to decipher complex access scenarios, write secure policies, and protect sensitive cloud resources. What you'll learn: Understand the foundational mechanics of the AWS IAM evaluation logic; Differentiate between identity-based policies and resource-based policies; Configure trust policies to delegate access securely using IAM roles; Implement the principle of least privilege using condition keys and boundaries; Apply modern security practices like Attribute-Based Access Control (ABAC); Troubleshoot access-denied errors systematically by analyzing policy structures. Starting with core terminology and basic IAM concepts, this course guides you through step-by-step written scenarios, policy breakdowns, and practical design exercises to reinforce your learning.
