AWS identity access management | Yubico (2024)

FAQs

Which answer is incorrect regarding IAM users? ›

The answer that is INCORRECT regarding IAM Users is 'IAM Users access AWS with the root account credentials'. IAM Users do not use the root account credentials to access AWS, but instead, they are given their own set of credentials that are separate from the root account.

AWS recommends locking away your root user access keys and to not use them regularly as they provide full access to all AWS resources for all services, including billing information.

IAM provides authentication and authorization for AWS services. A service evaluates if an AWS request is allowed or denied. Access is denied by default and is allowed only when a policy explicitly grants access. You can attach policies to roles and resources to control access across AWS.

Features of IAM

Shared access to the AWS account. The main feature of IAM is that it allows you to create separate usernames and passwords for individual users or resources and delegate access. Granular permissions.

Technically, yes, there is a way to assume multiple IAM roles at the same time. But it doesn't mean what you intend. Assuming an IAM role doesn't modify who you are and doesn't modify what permissions you have -- contrary to the intuitive interpretation of what it might mean to assume a different identity.

IAM user limit is 5000 per AWS account.

IAM users and root user are granted permanent credentials, while roles are granted temporary credentials. As a best practice, we recommend that you require human users and workloads to access AWS resources using temporary credentials.

AWS Identity and Access Management (IAM) roles are entities you create and assign specific permissions to that allow trusted identities such as workforce identities and applications to perform actions in AWS.

Which one is the recommended best practice for identity and access management? ›

Adopt The Principle of Least Privilege

One of the most common roles and permissions best practices is applying the principle of least privilege. IAM least privilege encourages organizations to restrict access and permissions as much as possible, without interfering with users' daily workflows.

The purpose of IAM is to stop hackers while allowing authorized users to easily do everything they need to do, but not more than they're allowed to do. IAM implementations use a variety of tools and strategies to achieve this goal, but they all tend to follow the same basic structure.

Single point of failure (SPoF)

If the system is not well designed or implemented, the IAM system can be the downfall of an organization. A Single Point of Failure (SPoF) could assist a hacker in gaining access to the system. This could lead to account compromise and the breach of both sensitive and non-sensitive data.

IAM consists of four main components: Authentication, Authorization, Administration, and Auditing and Reporting. Advanced tools like Single Sign-On (SSO), Multifactor Authentication (MFA), and Identity Governance and Administration (IGA) are employed in IAM to enhance security and user experience.

The statement, 'It's safer to use Access Keys than it is to use IAM roles,' is False. Access keys and IAM roles are both authentication mechanisms used in AWS (Amazon Web Services) to access resources.

Answer. Cloud Identity domains. There are no "Organization Accounts" in Cloud IAM.

False. IAM Group is NOT truly an identity because it cannot be identified as a Principal in a resource-based or trust policy. It is only a way to attach policies to multiple users at one time.

The valid access types for IAM users are using the AWS Software Developers Kit, programmatic access via command line, and AWS Management Console Access.
