Section 1: IAM and AWS – Critical Concepts, Definitions, and Tools

Identity is the most granular unit of security. To ensure the confidentiality, integrity, and availability of a system, that system's infrastructure, applications, APIs, and endpoints must all be identifiable, authenticated, and authorized in order to perform its functions. The AWS platform operates under a rigid identity-centric model. Bridging that model with your own organization's identity implementation can be daunting.
