AWS IAM

AWS Identity and Access Management (IAM) is a service that enables secure control of access to AWS resources. IAM allows users to create and manage IAM users and groups, assign permissions, and control who can access specific AWS services and resources. It supports fine-grained access control through policies that define permissions based on roles, conditions, and actions. IAM integrates with AWS services to provide centralized authentication and authorization, ensuring that users and applications have appropriate access levels. It enhances security by enabling best practices such as least privilege access and multi-factor authentication (MFA).
