Resources to learn more about IAM

IAM is a rich product, and you'll find many resources to help you learn more about how IAM can help you secure your AWS account and resources.

Identities

Consult these resources for creating, managing, and using identities.

• Manage identities in IAM Identity Center – Procedural information about creating users and group in IAM Identity Center.

• IAM Identities (users, user groups, and roles) – An in-depth discussion of users, groups, and roles.

Credentials (passwords, access keys, and MFA devices)

Review the following guides to manage passwords, access keys, and MFA devices for your AWS account and for IAM users.

• Managing user passwords in AWS – Describes options for managing passwords for IAM users in your account.

• Managing access keys for IAM users – Describes how access keys work and how you can use them to make programmatic calls to AWS. There are other more secure alternatives to access keys that we recommend you consider first. For more information, see Considerations and alternatives for long-term access keys in the AWS General Reference guide.

• Using multi-factor authentication (MFA) in AWS – Describes how to configure your account and IAM users to require both a password and a one-time use code that is generated on a device before sign-in is allowed. (This is sometimes called two-factor authentication.)

For general information about the types of credentials you use to access Amazon Web Services, see AWS Security Credentials in the AWS General Reference guide..

Permissions and policies

Learn the inner workings of IAM policies and find tips on the best ways to confer permissions:

• Policies and permissions in IAM – Introduces the policy language that is used to define permissions. Describes how permissions can be attached to users or groups or, for some AWS products, to resources themselves.

• IAM JSON policy elements reference – Provides descriptions and examples of each policy language element.

• Validating IAM policies – Find resources for JSON policy validation.

• Example IAM identity-based policies – Shows examples of policies for common tasks in various AWS products.

• AWS Policy Generator – Create custom policies by choosing products and actions from a list.

• IAM Policy Simulator – Test whether a policy would allow or deny a specific request to AWS.

Federation and delegation

You can grant access to resources in your AWS account for users who are authenticated (signed in) elsewhere. These can be IAM users in another AWS account (known as delegation), users who are authenticated with your organization's sign-in process, or users from an Internet identity provider like Login with Amazon, Facebook, Google, or any other OpenID Connect (OIDC) compatible identity provider. In these cases, the users get temporary security credentials to access AWS resources.

• IAM tutorial: Delegate access across AWS accounts using IAM roles – Guides you through granting cross-account access to an IAM user in another AWS account.

• Common scenarios for temporary credentials – Describes ways in which users can be federated into AWS after being authenticated outside of AWS.

• Web Identity Federation Playground – Lets you experiment with Login with Amazon, Google, or Facebook to authenticate and then make a call to Amazon S3.

IAM and other AWS products

Most AWS products are integrated with IAM so that you can use IAM features to help protect access to the resources in those products. The following resources discuss IAM and security for some of the most popular AWS products. For a complete list of products that work with IAM, including links to more information on each, see AWS services that work with IAM.

Using IAM with Amazon EC2

• Controlling Access to Amazon EC2 Resources – Describes how to use IAM features to permit users to administer Amazon EC2 instances, volumes, and more.

• Using instance profiles – Describes how to use IAM roles to securely provide credentials for applications that run on Amazon EC2 instances and that need access to other AWS products.

Using IAM with Amazon S3

• Managing Access Permissions to Your Amazon S3 Resources – Discusses the Amazon S3 security model for buckets and objects, which includes IAM policies.

• Writing IAM Policies: Grant Access to User-Specific Folders in an Amazon S3 Bucket – Discusses how to let users protect their own folders in Amazon S3. (For more posts about Amazon S3 and IAM, choose the S3 tag below the title of the blog post.)

Using IAM with Amazon RDS

• Using AWS Identity and Access Management (IAM) to Manage Access to Amazon RDS Resources – Describes how to use IAM to control access to database instances, database snapshots, and more.

• A Primer on RDS Resource-Level Permissions – Describes how to use IAM to control access to specific Amazon RDS instances.

Using IAM with Amazon DynamoDB

• Using IAM to Control Access to DynamoDB Resources – Describes how to use IAM to permit users to administer DynamoDB tables and indexes.

• The following video (8:55) explains how to provide access control for individual DynamoDB database items or attributes (or both).

General security practices

Find expert tips and guidance on the best ways to secure your AWS account and resources:

• Best Practices for Security, Identity, &, Compliance – Find resources for how to manage security across AWS accounts and products, including suggestions for security architecture, use of IAM, encryption and data security, and more.

• Identity and Access Management – The AWS Well-Architected Framework helps you understand key concepts, design principles, and architectural best practices for designing and running workloads in the cloud.

• Security best practices in IAM – Offers recommendations for ways to use IAM to help secure your AWS account and resources.

• AWS CloudTrail User Guide – Use AWS CloudTrail to track a history of API calls made to AWS and store that information in log files. This helps you determine which users and accounts accessed resources in your account, when the calls were made, what actions were requested, and more.
