What is IAM in AWS

IAM stands for Identity and Access Management. It is a web service that enables you to manage users and their permissions in AWS. With IAM, you can create and manage users, groups, and policies that control access to AWS resources. You can also use IAM to securely sign in to your AWS account from any computer or device.

IAM is a key component of the security infrastructure for AWS. It allows you to control who has access to your AWS resources, and what they can do with those resources. IAM is a powerful security tool that can be used to help prevent unauthorized access to your AWS resources.

How does IAM work?

IAM uses credentials to authenticate users when they sign in to their AWS account. The credentials can be in the form of an IAM user name and password, an IAM access key, or an AWS Identity and Access Management (IAM) role.

When you sign in to your AWS account, you are authenticated by using your credentials. Once you are authenticated, you will have access to all of the resources that you have been granted permissions to by the AWS administrators.

The benefits of using IAM

There are many benefits to using IAM, including:

  • IAM enables you to create and manage users and their permissions in AWS.
  • IAM enables you to control who has access to your AWS resources, and what they can do with those resources.
  • IAM is a key component of the security infrastructure for AWS.
  • IAM provides you with the ability to sign in to your AWS account from any computer or device.

What are the features of IAM?

Some of the key features of IAM include:

  1. IAM enables you to create and manage users and their permissions in AWS.
  2. IAM enables you to control who has access to your AWS resources, and what they can do with those resources.
  3. IAM is a key component of the security infrastructure for AWS.
  4. IAM provides you with the ability to sign in to your AWS account from any computer or device.
  5. IAM also includes built-in support for multifactor authentication. This allows you to require two forms of identification (such as a username and password, and a security token) for users who sign in to your AWS account.
  6. IAM also includes a built-in Role-Based Access Control (RBAC) system. This allows you to create predefined roles that can be assigned to users. These roles allow users to perform specific tasks, such as managing Amazon EC2 instances or accessing the S3 storage service.
  7. IAM also includes a built-in system for managing access keys. This allows you to create and manage access keys for users, and revoke access keys when they are no longer needed.
  8. IAM also includes a built-in system for tracking user activity. This allows you to track which users are accessing which resources, and when they are accessing those resources.
  9. IAM is a powerful security tool that can be used to help prevent unauthorized access to your AWS resources.

How do I get started with IAM?
