AWS IAM Groups

AWS Identity and Access Management (IAM) Groups are collections of IAM users that allow you to manage permissions for multiple users simultaneously. By grouping users, you can assign permissions to the group instead of individually assigning them to each user, improving efficiency and management.

Definition of IAM Groups

An IAM group is a collection of IAM users. You can use groups to manage permissions for a collection of users easily.

Benefits of Using IAM Groups

• Centralized management of user permissions.
• Simplifies the process of granting or revoking permissions.
• Encourages best practices by adhering to the principle of least privilege.

Step-by-Step Process

1. Log into the AWS Management Console.
2. Navigate to the IAM service.
3. Click on "Groups" in the left navigation pane.
4. Click on the "Create New Group" button.
5. Enter a name for your group.
6. Assign permissions by selecting policies from the list.
7. Click on "Create Group" to finalize.

Example of IAM Group Creation using AWS CLI

aws iam create-group --group-name MyGroup

To ensure secure and efficient use of IAM Groups, consider the following best practices:

• Always use the principle of least privilege.
• Regularly review group memberships and permissions.
• Utilize AWS Managed Policies when possible for standardized permissions.
• Implement Multi-Factor Authentication (MFA) for sensitive operations.
