Authorization and Authentication in AWS

Short summary

AWS IAM (Identity and Access Management) controls authentication and authorization: proving who you are and what resources you can access. The service provides Users, Policies, Groups, and Roles to manage permissions—Users are individual accounts, Policies grant permissions, Groups simplify policy attachment, and Roles enable cross-service communication. The tutorial walks through creating an IAM user in the AWS console and attaching policies to grant specific service access like EC2.

• •Use Users, Policies, Groups, and Roles to manage AWS access instead of sharing root credentials
