What does AWS IAM stand for?

AWS IAM stands for Identity and Access Management. This service enables users to control who can access specific AWS resources and services in a secure manner. Through IAM, administrators can create and manage AWS users and groups, and set permissions to allow or deny access to AWS resources.

The significance of IAM lies in its ability to enforce security policies in cloud environments, allowing organizations to ensure that only authorized users have access to sensitive data and resources. This is essential for maintaining compliance with regulatory standards and protecting against unauthorized access.

In IAM, users can be assigned roles that dictate what actions they are permitted to undertake within the AWS ecosystem, thereby reinforcing the security model of AWS. Overall, Identity and Access Management is a fundamental aspect of managing security in AWS, making it a crucial concept for anyone working with cloud services.
