With AWS Identity and Access Management (IAM), you can specify who or what can access services and resources in AWS, centrally manage fine-grained permissions, and analyze access to refine permissions across AWS. Set and manage guardrails and fine-grained access controls for your workforce and workloads. Manage identities across single AWS accounts or centrally connect identities to multiple AWS accounts. Grant temporary security credentials for workloads that access your AWS resources. Continually analyze access to right-size permissions on the journey to least privilege.
