What is IAM (Identity and Access Management)?
A framework for managing digital identities and controlling who can access which cloud resources and services.
IAM defines who (identities) can do what (permissions) on which resources. Users, groups, and roles are assigned policies that grant or deny specific actions. The principle of least privilege dictates granting only the minimum necessary permissions.
IAM policies in AWS use JSON to define allowed/denied actions. Multi-factor authentication (MFA) adds extra security. Service accounts and roles enable secure machine-to-machine communication without long-lived credentials.
