Working with AWS IAM Users

This lists all IAM users in an AWS account, providing key details like usernames, user IDs, and creation dates. Essential for managing permissions and auditing access, this function supports security and compliance protocols by offering a clear view of user entities and their access levels. It's instrumental in enforcing security policies and the principle of least privilege in AWS resource access management.

This task creates an IAM user which is an identity with specific permissions to access and manage AWS resources. This allows for fine-grained access control by assigning individualized permissions or roles to each user, rather than using root account credentials. Creating an IAM user is essential for securely managing access to AWS services and resources.

In AWS, policies define how operations are allowed or denied. This task attaches policies to an IAM user which in turn sets permissions on what actions that user can and cannot perform within AWS services. Essentially, it's a way to control a user's access to AWS resources. Policies can be predefined by AWS, like managed policies, or custom-defined by users. By strategically attaching and detaching policies, AWS administrators can finely tune access permissions for individual IAM users or groups.

This task deletes an IAM user in AWS which is a critical step in managing access to AWS resources. This process ensures that the user no longer has permission to perform actions or access resources. It involves several key steps: detaching all associated policies, removing any login profiles or access keys, and finally, deleting the user itself. This action is irreversible, and once the user is deleted, they cannot access the AWS Management Console, AWS CLI, or API operations unless recreated. Properly removing users helps in maintaining a secure and tidy AWS environment, especially when individuals no longer require access or have changed roles.
