Identity and access management for AWS Private 5G - AWS Private 5G

Identity and access management for AWS Private 5G

AWS Identity and Access Management (IAM) is an AWS service that helps an administrator securely control access to AWS resources. IAM administrators control who can be authenticated (signed in) and authorized (have permissions) to use AWS resources. IAM enables you to create users and groups under your AWS account. You control the permissions that users have to perform tasks using AWS resources. You can use IAM for no additional charge.

By default, IAM users don't have permissions for AWS Private 5G resources and operations. To allow IAM users to manage Private 5G resources, you must create an IAM policy that explicitly grants them permissions, and attach the policy to the IAM users or groups that require those permissions.

When you attach a policy to a user or group of users, it allows or denies the users permission to perform the specified tasks on the specified resources. For more information, see Policies and Permissions in the IAM User Guide guide.

Before you use IAM to manage access to Private 5G, you should understand what IAM features are available to use with Private 5G. To get a high-level view of how Private 5G and other AWS services work with IAM, see AWS Services That Work with IAM in the IAM User Guide.

Policy structure

An IAM policy is a JSON document that consists of one or more statements. Each statement is structured as follows.

{ "Statement":[{ "Effect":"effect", "Action":"action", "Resource":"arn", "Condition":{ "condition":{ "key":"value" } } } ] }

There are various elements that make up a statement:

  • Effect: The effect can be Allow or Deny. By default, IAM users don't have permission to use resources and API actions, so all requests are denied. An explicit allow overrides the default. An explicit deny overrides any allows.

  • Action: The action is the specific API action for which you are granting or denying permission.

  • Resource: The resource that's affected by the action. Some API actions allow you to include specific resources in your policy that can be created or modified by the action. To specify a resource in the statement, you need to use its Amazon Resource Name (ARN).

  • Condition: Conditions are optional. They can be used to control when your policy is in effect.

Example policies

In an IAM policy statement, you can specify any API action from any service that supports IAM. For Private 5G, use the following prefix with the name of the API action: private-networks:. For example: private-networks:GetNetwork.

To specify multiple actions in a single statement, separate them with commas.

"Action": ["private-networks:CreateNetwork", "private-networks:GetNetwork"]

You can also specify multiple actions using wildcards. For example, you can specify all Private 5G API actions whose name begins with the word "Get".

"Action": "private-networks:Get*"

To specify all Private 5G API actions, use the * wildcard.

"Action": "private-networks:*"

Using temporary credentials with Private 5G

Private 5G supports using temporary credentials. You can use temporary credentials to sign in with federation, assume an IAM role, or assume a cross-account role. To get temporary security credentials, use the AWS STS API operations; for example, AssumeRole or GetFederationToken.
