Access Control Service

AWS IAM

Identity and Access Management

AWS Identity and Access Management (IAM) is a web service that helps you securely control access to AWS resources. You use IAM to control who is authenticated (signed in) and who is authorized (has permissions) to use resources.

Overview

What is AWS IAM?

AWS Identity and Access Management (IAM) enables you to manage access to AWS services and resources securely. Using IAM, you can create and manage AWS users and groups, and use permissions to allow and deny their access to AWS resources.

Introduction

AWS Identity and Access Management (IAM) is a web service that helps you securely control access to AWS resources. With IAM, you can centrally manage permissions that control which AWS resources users can access.

IAM is a feature of your AWS account offered at no additional charge. You will be charged only for the use of other AWS services by your users. This is a global service and does not require you to specify a region.

Fine-Grained Permissions
