Step 2: Create a user and policy

In this step, you create a user with a policy that grants access to your Amazon DynamoDB Accelerator (DAX) cluster and to DynamoDB using AWS Identity and Access Management. You can then run applications that interact with your DAX cluster.

Sign up for an AWS account

If you do not have an AWS account, complete the following steps to create one.

To sign up for an AWS account

1. Open https://portal.aws.amazon.com/billing/signup.

2. Follow the online instructions.

   Part of the sign-up procedure involves receiving a phone call and entering a verification code on the phone keypad.

   When you sign up for an AWS account, an AWS account root user is created. The root user has access to all AWS services and resources in the account. As a security best practice, assign administrative access to an administrative user, and use only the root user to perform tasks that require root user access.

AWS sends you a confirmation email after the sign-up process is complete. At any time, you can view your current account activity and manage your account by going to https://aws.amazon.com/ and choosing My Account.

Create an administrative user

After you sign up for an AWS account, create an administrative user so that you don't use the root user for everyday tasks.

Secure your AWS account root user

1. Sign in to the AWS Management Console as the account owner by choosing Root user and entering your AWS account email address. On the next page, enter your password.

For help signing in by using root user, see Signing in as the root user in the AWS Sign-In User Guide.

1. Turn on multi-factor authentication (MFA) for your root user.

   For instructions, see Enable a virtual MFA device for your AWS account root user (console) in the IAM User Guide.

Create an administrative user

• For your daily administrative tasks, grant administrative access to an administrative user in AWS IAM Identity Center (successor to AWS Single Sign-On).

  For instructions, see Getting started in the AWS IAM Identity Center (successor to AWS Single Sign-On) User Guide.

Sign in as the administrative user

• To sign in with your IAM Identity Center user, use the sign-in URL that was sent to your email address when you created the IAM Identity Center user.

  For help signing in using an IAM Identity Center user, see Signing in to the AWS access portal in the AWS Sign-In User Guide.

To provide access, add permissions to your users, groups, or roles:

• Users and groups in AWS IAM Identity Center (successor to AWS Single Sign-On):

  Create a permission set. Follow the instructions in Create a permission set in the AWS IAM Identity Center (successor to AWS Single Sign-On) User Guide.

• Users managed in IAM through an identity provider:

  Create a role for identity federation. Follow the instructions in Creating a role for a third-party identity provider (federation) in the IAM User Guide.

• IAM users:

  • Create a role that your user can assume. Follow the instructions in Creating a role for an IAM user in the IAM User Guide.
  • (Not recommended) Attach a policy directly to a user or add a user to a user group. Follow the instructions in Adding permissions to a user (console) in the IAM User Guide.

To use the JSON policy editor to create a policy

1. Sign in to the AWS Management Console and open the IAM console at https://console.aws.amazon.com/iam/.

2. In the navigation column on the left, choose Policies.

   If this is your first time choosing Policies, the Welcome to Managed Policies page appears. Choose Get Started.

3. At the top of the page, choose Create policy.

4. Choose the JSON tab.

5. Enter or paste a JSON policy document. For details about the IAM policy language, see IAM JSON policy reference in the IAM User Guide.

6. Resolve any security warnings, errors, or general warnings generated during policy validation, and then choose Review policy. Note
   You can switch between the Visual editor and JSON tabs any time. However, if you make changes or choose Review policy in the Visual editor tab, IAM might restructure your policy to optimize it for the visual editor. For more information, see Policy restructuring in the IAM User Guide.

7. On the Review policy page, enter a Name and an optional Description for the policy that you are creating. Review the policy Summary to see the permissions that are granted by your policy. Then choose Create policy to save your work.

Policy document – Copy and paste the following document to create the JSON policy.

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Action": [
                "dax:*"
            ],
            "Effect": "Allow",
            "Resource": [
                "*"
            ]
        },
        {
            "Action": [
                "dynamodb:*"
            ],
            "Effect": "Allow",
            "Resource": [
                "*"
            ]
        }
    ]
}
