AWS IAM is a key security service that helps keep track of who has access to what in AWS environments. It lets administrators create and manage users, groups, roles, and policies while making sure that users only have the permissions they need. IAM works with multi-factor authentication (MFA), federation, and service-linked roles to make security even better. IAM is necessary for keeping cloud workloads safe because it has centralized governance, audit trails, and help with compliance.
