# Security in AWS TNB
Security

Cloud security at AWS is the highest priority. As an AWS customer, you benefit from data centers and network architectures that are built to meet the requirements of the most security-sensitive organizations.

Security is a shared responsibility between AWS and you. The [shared responsibility model](https://aws.amazon.com/compliance/shared-responsibility-model/) describes this as security *of* the cloud and security *in* the cloud:
+ **Security of the cloud** – AWS is responsible for protecting the infrastructure that runs AWS services in the AWS Cloud. AWS also provides you with services that you can use securely. Third-party auditors regularly test and verify the effectiveness of our security as part of the [AWS Compliance Programs](https://aws.amazon.com/compliance/programs/). To learn about the compliance programs that apply to AWS Telco Network Builder, see [AWS Services in Scope by Compliance Program](https://aws.amazon.com/compliance/services-in-scope/).
+ **Security in the cloud** – Your responsibility is determined by the AWS service that you use. You are also responsible for other factors including the sensitivity of your data, your company’s requirements, and applicable laws and regulations. 

This documentation helps you understand how to apply the shared responsibility model when using AWS TNB. The following topics show you how to configure AWS TNB to meet your security and compliance objectives. You also learn how to use other AWS services that help you to monitor and secure your AWS TNB resources.

# Data protection in AWS TNB
Data protection

The AWS [shared responsibility model](https://aws.amazon.com/compliance/shared-responsibility-model/) applies to data protection in AWS Telco Network Builder. As described in this model, AWS is responsible for protecting the global infrastructure that runs all of the AWS Cloud. You are responsible for maintaining control over your content that is hosted on this infrastructure. You are also responsible for the security configuration and management tasks for the AWS services that you use. For more information about data privacy, see the [Data Privacy FAQ](https://aws.amazon.com/compliance/data-privacy-faq/). For information about data protection in Europe, see the [AWS Shared Responsibility Model and GDPR](https://aws.amazon.com/blogs/security/the-aws-shared-responsibility-model-and-gdpr/) blog post on the *AWS Security Blog*.

For data protection purposes, we recommend that you protect AWS account credentials and set up individual users with AWS IAM Identity Center or AWS Identity and Access Management (IAM). That way, each user is given only the permissions necessary to fulfill their job duties. We also recommend that you secure your data in the following ways:
+ Use multi-factor authentication (MFA) with each account.
+ Use SSL/TLS to communicate with AWS resources. We require TLS 1.2 and recommend TLS 1.3.
+ Set up API and user activity logging with AWS CloudTrail. For information about using CloudTrail trails to capture AWS activities, see [Working with CloudTrail trails](https://docs.aws.amazon.com/awscloudtrail/latest/userguide/cloudtrail-trails.html) in the *AWS CloudTrail User Guide*.
+ Use AWS encryption solutions, along with all default security controls within AWS services.
+ Use advanced managed security services such as Amazon Macie, which assists in discovering and securing sensitive data that is stored in Amazon S3.
+ If you require FIPS 140-3 validated cryptographic modules when accessing AWS through a command line interface or an API, use a FIPS endpoint. For more information about the available FIPS endpoints, see [Federal Information Processing Standard (FIPS) 140-3](https://aws.amazon.com/compliance/fips/).

We strongly recommend that you never put confidential or sensitive information, such as your customers' email addresses, into tags or free-form text fields such as a **Name** field. This includes when you work with AWS TNB or other AWS services using the console, API, AWS CLI, or AWS SDKs. Any data that you enter into tags or free-form text fields used for names may be used for billing or diagnostic logs. If you provide a URL to an external server, we strongly recommend that you do not include credentials information in the URL to validate your request to that server.

## Data handling


When you close your AWS account, AWS TNB marks your data for deletion and removes it from any use. If you reactivate your AWS account within 90 days, AWS TNB restores your data. After 120 days, AWS TNB permanently deletes your data. AWS TNB also terminates your networks and deletes your function packages and your network packages.

## Encryption at rest


AWS TNB always encrypts all data stored in the service at rest without requiring any additional configuration. This encryption is automatic through AWS Key Management Service.

## Encryption in transit


AWS TNB secures all data in transit using Transport Layer Security (TLS) 1.2.

It is your responsibility to encrypt data between your simulation agents and their clients.

## Inter-network traffic privacy


AWS TNB compute resources reside in a virtual private cloud (VPC) shared by all customers. All internal AWS TNB traffic stayed within the AWS network and doesn't traverse the internet. Connections between your simulation agents and their clients are routed over the internet.

# Identity and access management for AWS TNB
Identity and access management

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 TNB resources. IAM is an AWS service that you can use with no additional charge.

](security_iam_troubleshoot.md)

## Audience


How you use AWS Identity and Access Management (IAM) differs based on your role:
+ **Service user** - request permissions from your administrator if you cannot access features (see [Troubleshooting AWS Telco Network Builder identity and access](security_iam_troubleshoot.md))
+ **Service administrator** - determine user access and submit permission requests (see [How AWS TNB works with IAM](security_iam_service-with-iam.md))
+ **IAM administrator** - write policies to manage access (see [Identity-based policy examples for AWS Telco Network Builder](security_iam_id-based-policy-examples.md))

## Authenticating with identities


Authentication is how you sign in to AWS using your identity credentials. You must be authenticated as the AWS account root user, an IAM user, or by assuming an IAM role.

You can sign in as a federated identity using credentials from an identity source like AWS IAM Identity Center (IAM Identity Center), single sign-on authentication, or Google/Facebook credentials. For more information about signing in, see [How to sign in to your AWS account](https://docs.aws.amazon.com/signin/latest/userguide/how-to-sign-in.html) in the *AWS Sign-In User Guide*.

For programmatic access, AWS provides an SDK and CLI to cryptographically sign requests. For more information, see [AWS Signature Version 4 for API requests](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_sigv.html) in the *IAM User Guide*.

### AWS account root user


 When you create an AWS account, you begin with one sign-in identity called the AWS account *root user* that has complete access to all AWS services and resources. We strongly recommend that you don't use the root user for everyday tasks. For tasks that require root user credentials, see [Tasks that require root user credentials](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_root-user.html#root-user-tasks) in the *IAM User Guide*. 

### Federated identity


As a best practice, require human users to use federation with an identity provider to access AWS services using temporary credentials.

A *federated identity* is a user from your enterprise directory, web identity provider, or Directory Service that accesses AWS services using credentials from an identity source. Federated identities assume roles that provide temporary credentials.

For centralized access management, we recommend AWS IAM Identity Center. For more information, see [What is IAM Identity Center?](https://docs.aws.amazon.com/singlesignon/latest/userguide/what-is.html) in the *AWS IAM Identity Center User Guide*.

### IAM users and groups


An *[IAM user](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_users.html)* is an identity with specific permissions for a single person or application. We recommend using temporary credentials instead of IAM users with long-term credentials. For more information, see [Require human users to use federation with an identity provider to access AWS using temporary credentials](https://docs.aws.amazon.com/IAM/latest/UserGuide/best-practices.html#bp-users-federation-idp) in the *IAM User Guide*.

An [https://docs.aws.amazon.com/IAM/latest/UserGuide/id_groups.html](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_groups.html) specifies a collection of IAM users and makes permissions easier to manage for large sets of users. For more information, see [Use cases for IAM users](https://docs.aws.amazon.com/IAM/latest/UserGuide/gs-identities-iam-users.html) in the *IAM User Guide*.

### IAM roles


An *[IAM role](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles.html)* is an identity with specific permissions that provides temporary credentials. You can assume a role by [switching from a user to an IAM role (console)](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_use_switch-role-console.html) or by calling an AWS CLI or AWS API operation. For more information, see [Methods to assume a role](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_manage-assume.html) in the *IAM User Guide*.

IAM roles are useful for federated user access, temporary IAM user permissions, cross-account access, cross-service access, and applications running on Amazon EC2. For more information, see [Cross account resource access in IAM](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies-cross-account-resource-access.html) in the *IAM User Guide*.

## Managing access using policies


You control access in AWS by creating policies and attaching them to AWS identities or resources. A policy defines permissions when associated with an identity or resource. AWS evaluates these policies when a principal makes a request. Most policies are stored in AWS as JSON documents. For more information about JSON policy documents, see [Overview of JSON policies](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies.html#access_policies-json) in the *IAM User Guide*.

Using policies, administrators specify who has access to what by defining which **principal** can perform **actions** on what **resources**, and under what **conditions**.

By default, users and roles have no permissions. An IAM administrator creates IAM policies and adds them to roles, which users can then assume. IAM policies define permissions regardless of the method used to perform the operation.

### Identity-based policies


Identity-based policies are JSON permissions policy documents that you attach to an identity (user, group, or role). These policies control what actions identities can perform, on which resources, and under what conditions. To learn how to create an identity-based policy, see [Define custom IAM permissions with customer managed policies](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies_create.html) in the *IAM User Guide*.

Identity-based policies can be *inline policies* (embedded directly into a single identity) or *managed policies* (standalone policies attached to multiple identities). To learn how to choose between managed and inline policies, see [Choose between managed policies and inline policies](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies-choosing-managed-or-inline.html) in the *IAM User Guide*.

### Resource-based policies


Resource-based policies are JSON policy documents that you attach to a resource. Examples include IAM *role trust policies* and Amazon S3 *bucket policies*. In services that support resource-based policies, service administrators can use them to control access to a specific resource. You must [specify a principal](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_elements_principal.html) in a resource-based policy.

Resource-based policies are inline policies that are located in that service. You can't use AWS managed policies from IAM in a resource-based policy.

### Other policy types


AWS supports additional policy types that can set the maximum permissions granted by more common policy types:
+ **Permissions boundaries** – Set the maximum permissions that an identity-based policy can grant to an IAM entity. For more information, see [Permissions boundaries for IAM entities](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies_boundaries.html) in the *IAM User Guide*.
+ **Service control policies (SCPs)** – Specify the maximum permissions for an organization or organizational unit in AWS Organizations. For more information, see [Service control policies](https://docs.aws.amazon.com/organizations/latest/userguide/orgs_manage_policies_scps.html) in the *AWS Organizations User Guide*.
+ **Resource control policies (RCPs)** – Set the maximum available permissions for resources in your accounts. For more information, see [Resource control policies (RCPs)](https://docs.aws.amazon.com/organizations/latest/userguide/orgs_manage_policies_rcps.html) in the *AWS Organizations User Guide*.
+ **Session policies** – Advanced policies passed as a parameter when creating a temporary session for a role or federated user. For more information, see [Session policies](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies.html#policies_session) in the *IAM User Guide*.

### Multiple policy types


When multiple types of policies apply to a request, the resulting permissions are more complicated to understand. To learn how AWS determines whether to allow a request when multiple policy types are involved, see [Policy evaluation logic](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_evaluation-logic.html) in the *IAM User Guide*.

## Identity-based policies for AWS TNB
Identity-based policies

**Supports identity-based policies:** Yes

Identity-based policies are JSON permissions policy documents that you can attach to an identity, such as an IAM user, group of users, or role. These policies control what actions users and roles can perform, on which resources, and under what conditions. To learn how to create an identity-based policy, see [Define custom IAM permissions with customer managed policies](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies_create.html) in the *IAM User Guide*.

With IAM identity-based policies, you can specify allowed or denied actions and resources as well as the conditions under which actions are allowed or denied. To learn about all of the elements that you can use in a JSON policy, see [IAM JSON policy elements reference](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_elements.html) in the *IAM User Guide*.

### Identity-based policy examples for AWS TNB


To view examples of AWS TNB identity-based policies, see [Identity-based policy examples for AWS Telco Network Builder](security_iam_id-based-policy-examples.md).

## Resource-based policies within AWS TNB
Resource-based policies

**Supports resource-based policies:** No 

Resource-based policies are JSON policy documents that you attach to a resource. Examples of resource-based policies are IAM *role trust policies* and Amazon S3 *bucket policies*. In services that support resource-based policies, service administrators can use them to control access to a specific resource. For the resource where the policy is attached, the policy defines what actions a specified principal can perform on that resource and under what conditions. You must [specify a principal](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_elements_principal.html) in a resource-based policy. Principals can include accounts, users, roles, federated users, or AWS services.

To enable cross-account access, you can specify an entire account or IAM entities in another account as the principal in a resource-based policy. For more information, see [Cross account resource access in IAM](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies-cross-account-resource-access.html) in the *IAM User Guide*.

## Policy actions for AWS TNB
Policy actions

**Supports policy actions:** Yes

Administrators can use AWS JSON policies to specify who has access to what. That is, which **principal** can perform **actions** on what **resources**, and under what **conditions**.

The `Action` element of a JSON policy describes the actions that you can use to allow or deny access in a policy. Include actions in a policy to grant permissions to perform the associated operation.

To see a list of AWS TNB actions, see [Actions defined by AWS Telco Network Builder](https://docs.aws.amazon.com/service-authorization/latest/reference/list_awstelconetworkbuilder.html#awstelconetworkbuilder-actions-as-permissions) in the *Service Authorization Reference*.

Policy actions in AWS TNB use the following prefix before the action:

```
tnb
```

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

```
"Action": [
      "tnb:CreateSolFunctionPackage",
      "tnb:DeleteSolFunctionPackage"
]
```

You can specify multiple actions using wildcards (\$1). For example, to specify all actions that begin with the word `List`, include the following action:

```
"Action": "tnb:List*"
```

To view examples of AWS TNB identity-based policies, see [Identity-based policy examples for AWS Telco Network Builder](security_iam_id-based-policy-examples.md).

## Policy resources for AWS TNB
Policy resources

**Supports policy resources:** Yes

Administrators can use AWS JSON policies to specify who has access to what. That is, which **principal** can perform **actions** on what **resources**, and under what **conditions**.

The `Resource` JSON policy element specifies the object or objects to which the action applies. As a best practice, specify a resource using its [Amazon Resource Name (ARN)](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference-arns.html). For actions that don't support resource-level permissions, use a wildcard (\$1) to indicate that the statement applies to all resources.

```
"Resource": "*"
```

To see a list of AWS TNB resource types and their ARNs, see [Resources defined by AWS Telco Network Builder](https://docs.aws.amazon.com/service-authorization/latest/reference/list_awstelconetworkbuilder.html#awstelconetworkbuilder-resources-for-iam-policies) in the *Service Authorization Reference*. To learn with which actions you can specify the ARN of each resource, see [Actions defined by AWS Telco Network Builder](https://docs.aws.amazon.com/service-authorization/latest/reference/list_awstelconetworkbuilder.html#awstelconetworkbuilder-actions-as-permissions).

To view examples of AWS TNB identity-based policies, see [Identity-based policy examples for AWS Telco Network Builder](security_iam_id-based-policy-examples.md).

## Policy condition keys for AWS TNB
Policy condition keys

**Supports service-specific policy condition keys:** Yes

Administrators can use AWS JSON policies to specify who has access to what. That is, which **principal** can perform **actions** on what **resources**, and under what **conditions**.

The `Condition` element specifies when statements execute based on defined criteria. You can create conditional expressions that use [condition operators](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_elements_condition_operators.html), such as equals or less than, to match the condition in the policy with values in the request. To see all AWS global condition keys, see [AWS global condition context keys](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_condition-keys.html) in the *IAM User Guide*.

To see a list of AWS TNB condition keys, see [Condition keys for AWS Telco Network Builder](https://docs.aws.amazon.com/service-authorization/latest/reference/list_awstelconetworkbuilder.html#awstelconetworkbuilder-policy-keys) in the *Service Authorization Reference*. To learn with which actions and resources you can use a condition key, see [Actions defined by AWS Telco Network Builder](https://docs.aws.amazon.com/service-authorization/latest/reference/list_awstelconetworkbuilder.html#awstelconetworkbuilder-actions-as-permissions).

To view examples of AWS TNB identity-based policies, see [Identity-based policy examples for AWS Telco Network Builder](security_iam_id-based-policy-examples.md).

## ACLs in AWS TNB
ACLs

**Supports ACLs:** No 

Access control lists (ACLs) control which principals (account members, users, or roles) have permissions to access a resource. ACLs are similar to resource-based policies, although they do not use the JSON policy document format.

## ABAC with AWS TNB
ABAC

**Supports ABAC (tags in policies):** Yes

Attribute-based access control (ABAC) is an authorization strategy that defines permissions based on attributes called tags. You can attach tags to IAM entities and AWS resources, then design ABAC policies to allow operations when the principal's tag matches the tag on the resource.

To control access based on tags, you provide tag information in the [condition element](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_elements_condition.html) of a policy using the `aws:ResourceTag/key-name`, `aws:RequestTag/key-name`, or `aws:TagKeys` condition keys.

If a service supports all three condition keys for every resource type, then the value is **Yes** for the service. If a service supports all three condition keys for only some resource types, then the value is **Partial**.

For more information about ABAC, see [Define permissions with ABAC authorization](https://docs.aws.amazon.com/IAM/latest/UserGuide/introduction_attribute-based-access-control.html) in the *IAM User Guide*. To view a tutorial with steps for setting up ABAC, see [Use attribute-based access control (ABAC)](https://docs.aws.amazon.com/IAM/latest/UserGuide/tutorial_attribute-based-access-control.html) in the *IAM User Guide*.

## Using temporary credentials with AWS TNB
Temporary credentials

**Supports temporary credentials:** Yes

Temporary credentials provide short-term access to AWS resources and are automatically created when you use federation or switch roles. AWS recommends that you dynamically generate temporary credentials instead of using long-term access keys. For more information, see [Temporary security credentials in IAM](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp.html) and [AWS services that work with IAM](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_aws-services-that-work-with-iam.html) in the *IAM User Guide*.

## Cross-service principal permissions for AWS TNB
Principal permissions

**Supports forward access sessions (FAS):** Yes

 Forward access sessions (FAS) use the permissions of the principal calling an AWS service, combined with the requesting AWS service to make requests to downstream services. For policy details when making FAS requests, see [Forward access sessions](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_forward_access_sessions.html). 

## Service roles for AWS TNB
Service roles

**Supports service roles:** No 

 A service role is an [IAM role](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles.html) that a service assumes to perform actions on your behalf. An IAM administrator can create, modify, and delete a service role from within IAM. For more information, see [Create a role to delegate permissions to an AWS service](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_create_for-service.html) in the *IAM User Guide*. 

## Service-linked roles for AWS TNB
Service-linked roles

**Supports service-linked roles:** No 

 A service-linked role is a type of service role that is linked to an AWS service. The service can assume the role to perform an action on your behalf. Service-linked roles appear in your AWS account and are owned by the service. An IAM administrator can view, but not edit the permissions for service-linked roles. 

# Identity-based policy examples for AWS Telco Network Builder
Identity-based policy examples

By default, users and roles don't have permission to create or modify AWS TNB resources. To grant users permission to perform actions on the resources that they need, an IAM administrator can create IAM policies.

To learn how to create an IAM identity-based policy by using these example JSON policy documents, see [Create IAM policies (console)](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies_create-console.html) in the *IAM User Guide*.

For details about actions and resource types defined by AWS TNB, including the format of the ARNs for each of the resource types, see [Actions, resources, and condition keys for AWS Telco Network Builder](https://docs.aws.amazon.com/service-authorization/latest/reference/list_awstelconetworkbuilder.html) in the *Service Authorization Reference*.

## Policy best practices


Identity-based policies determine whether someone can create, access, or delete AWS TNB resources in your account. These actions can incur costs for your AWS account. When you create or edit identity-based policies, follow these guidelines and recommendations:
+ **Get started with AWS managed policies and move toward least-privilege permissions** – To get started granting permissions to your users and workloads, use the *AWS managed policies* that grant permissions for many common use cases. They are available in your AWS account. We recommend that you reduce permissions further by defining AWS customer managed policies that are specific to your use cases. For more information, see [AWS managed policies](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies_managed-vs-inline.html#aws-managed-policies) or [AWS managed policies for job functions](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies_job-functions.html) in the *IAM User Guide*.
+ **Apply least-privilege permissions** – When you set permissions with IAM policies, grant only the permissions required to perform a task. You do this by defining the actions that can be taken on specific resources under specific conditions, also known as *least-privilege permissions*. For more information about using IAM to apply permissions, see [ Policies and permissions in IAM](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies.html) in the *IAM User Guide*.
+ **Use conditions in IAM policies to further restrict access** – You can add a condition to your policies to limit access to actions and resources. For example, you can write a policy condition to specify that all requests must be sent using SSL. You can also use conditions to grant access to service actions if they are used through a specific AWS service, such as CloudFormation. For more information, see [ IAM JSON policy elements: Condition](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_elements_condition.html) in the *IAM User Guide*.
+ **Use IAM Access Analyzer to validate your IAM policies to ensure secure and functional permissions** – IAM Access Analyzer validates new and existing policies so that the policies adhere to the IAM policy language (JSON) and IAM best practices. IAM Access Analyzer provides more than 100 policy checks and actionable recommendations to help you author secure and functional policies. For more information, see [Validate policies with IAM Access Analyzer](https://docs.aws.amazon.com/IAM/latest/UserGuide/access-analyzer-policy-validation.html) in the *IAM User Guide*.
+ **Require multi-factor authentication (MFA)** – If you have a scenario that requires IAM users or a root user in your AWS account, turn on MFA for additional security. To require MFA when API operations are called, add MFA conditions to your policies. For more information, see [ Secure API access with MFA](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_mfa_configure-api-require.html) in the *IAM User Guide*.

For more information about best practices in IAM, see [Security best practices in IAM](https://docs.aws.amazon.com/IAM/latest/UserGuide/best-practices.html) in the *IAM User Guide*.

## Using the AWS TNB console
Using the console

To access the AWS Telco Network Builder console, you must have a minimum set of permissions. These permissions must allow you to list and view details about the AWS TNB resources in your AWS account. If you create an identity-based policy that is more restrictive than the minimum required permissions, the console won't function as intended for entities (users or roles) with that policy.

You don't need to allow minimum console permissions for users that are making calls only to the AWS CLI or the AWS API. Instead, allow access to only the actions that match the API operation that they're trying to perform.

## Service role policy examples


As an administrator, you own and manage the resources that AWS TNB creates as defined by the environment and service templates. You must attach IAM service roles to your account to permit AWS TNB to create resources for your network life-cycle management. 

A IAM service role allows AWS TNB to make calls to resources on your behalf to instantiate and manage your networks. If you specify a service role, AWS TNB uses that role’s credential.

You create the service role and its permission policy with the IAM service. For more information about creating a service role, see [Creating a role to delegate permissions to an AWS service](https://docs.aws.amazon.com//IAM/latest/UserGuide/id_roles_create_for-service.html) in the *IAM User Guide*.

### AWS TNB service role


As a member of the platform team, you can as an administrator create an AWS TNB service role and provide it to AWS TNB. This role allows AWS TNB to make calls to other services such as Amazon Elastic Kubernetes Service and CloudFormation to provision the required infrastructure for your network and provision network functions as defined in your NSD.

We recommend that you use the following IAM role and trust policy for your AWS TNB service role. When scoping down permission on this policy, keep in mind that AWS TNB may fail with Access Denied errors toward resources descoped from your policy.

The following code shows an AWS TNB service role policy:

### AWS TNB service role for Amazon EKS cluster


When you create an Amazon EKS resources in your NSD, you provide the `cluster_role` attribute to specify which role will be used to create your Amazon EKS cluster.

The following example shows a AWS CloudFormation template that creates a AWS TNB service role for the Amazon EKS cluster policy.

```
AWSTemplateFormatVersion: "2010-09-09"
Resources:
  TNBEKSClusterRole:
    Type: "AWS::IAM::Role"
    Properties:
      RoleName: "TNBEKSClusterRole"
      AssumeRolePolicyDocument:
        Version: "2012-10-17"
        Statement:
          - Effect: Allow
            Principal:
              Service:
                - eks.amazonaws.com
            Action:
              - "sts:AssumeRole"
      Path: /
      ManagedPolicyArns:
        - !Sub "arn:${AWS::Partition}:iam::aws:policy/AmazonEKSClusterPolicy"
```

For more information about IAM roles using AWS CloudFormation template, see the following sections in the *AWS CloudFormation User Guide*:

### AWS TNB service role for Amazon EKS node group


When you create an Amazon EKS node group resources in your NSD, you provide the `node_role` attribute to specify which role will be used to create your Amazon EKS node group.

### AWS TNB service role for Multus


When you create an Amazon EKS resource in your NSD and you want to manage Multus as part of your deployment template, you must provide the `multus_role` attribute to specify which role will be used for managing Multus.

The following example shows a CloudFormation template that creates a AWS TNB service role for a Multus policy.

```

### AWS TNB service role for a life-cycle hook policy


When your NSD or network function package uses a life-cycle hook, you need a service role to allow you to create an environment for execution of your life-cycle hooks.

**Note**  
Your life-cycle hook policy should be based on what your life-cycle hook is attempting to do.

The following example shows a CloudFormation template that creates a AWS TNB service role for a life-cycle hook policy.

```
AWSTemplateFormatVersion: "2010-09-09"
Resources:
  TNBHookRole:
    Type: "AWS::IAM::Role"
    Properties:
      RoleName: "TNBHookRole"
      AssumeRolePolicyDocument:
        Version: "2012-10-17"
        Statement:
          - Effect: Allow
            Principal:
              Service:
                - codebuild.amazonaws.com
            Action:
              - "sts:AssumeRole"
      Path: /
      ManagedPolicyArns:
        - !Sub "arn:${AWS::Partition}:iam::aws:policy/AdministratorAccess"
```

## Allow users to view their own permissions


This example shows how you might create a policy that allows IAM users to view the inline and managed policies that are attached to their user identity. This policy includes permissions to complete this action on the console or programmatically using the AWS CLI or AWS API.

```
{
    "Version": "2012-10-17",		 	 	 
    "Statement": [
        {
            "Sid": "ViewOwnUserInfo",
            "Effect": "Allow",
            "Action": [
                "iam:GetUserPolicy",
                "iam:ListGroupsForUser",
                "iam:ListAttachedUserPolicies",
                "iam:ListUserPolicies",
                "iam:GetUser"
            ],
            "Resource": ["arn:aws:iam::*:user/${aws:username}"]
        },
        {
            "Sid": "NavigateInConsole",
            "Effect": "Allow",
            "Action": [
                "iam:GetGroupPolicy",
                "iam:GetPolicyVersion",
                "iam:GetPolicy",
                "iam:ListAttachedGroupPolicies",
                "iam:ListGroupPolicies",
                "iam:ListPolicyVersions",
                "iam:ListPolicies",
                "iam:ListUsers"
            ],
            "Resource": "*"
        }
    ]
}
```

# Troubleshooting AWS Telco Network Builder identity and access
Troubleshooting

Use the following information to help you diagnose and fix common issues that you might encounter when working with AWS TNB and IAM.

**Topics**
+ [

## I am not authorized to perform an action in AWS TNB
](#security_iam_troubleshoot-no-permissions)
+ [

## I am not authorized to perform iam:PassRole
](#security_iam_troubleshoot-passrole)
+ [

## I want to allow people outside of my AWS account to access my AWS TNB resources
](#security_iam_troubleshoot-cross-account-access)

## I am not authorized to perform an action in AWS TNB


If you receive an error that you're not authorized to perform an action, your policies must be updated to allow you to perform the action.

The following example error occurs when the `mateojackson` IAM user tries to use the console to view details about a fictional `my-example-widget` resource but does not have the fictional `tnb:GetWidget` permissions.

```
User: arn:aws:iam::123456789012:user/mateojackson is not authorized to perform: tnb:GetWidget on resource: my-example-widget
```

In this case, Mateo's policy must be updated to allow him to access the `my-example-widget` resource using the `tnb:GetWidget` action.

If you need help, contact your AWS administrator. Your administrator is the person who provided you with your sign-in credentials.

## I am not authorized to perform iam:PassRole


If you receive an error that you're not authorized to perform the `iam:PassRole` action, your policies must be updated to allow you to pass a role to AWS TNB.

Some AWS services allow you to pass an existing role to that service instead of creating a new service role or service-linked role. To do this, you must have permissions to pass the role to the service.

The following example error occurs when an IAM user named `marymajor` tries to use the console to perform an action in AWS TNB. However, the action requires the service to have permissions that are granted by a service role. Mary does not have permissions to pass the role to the service.

```
User: arn:aws:iam::123456789012:user/marymajor is not authorized to perform: iam:PassRole
```

In this case, Mary's policies must be updated to allow her to perform the `iam:PassRole` action.

If you need help, contact your AWS administrator. Your administrator is the person who provided you with your sign-in credentials.

## I want to allow people outside of my AWS account to access my AWS TNB resources


You can create a role that users in other accounts or people outside of your organization can use to access your resources. You can specify who is trusted to assume the role. For services that support resource-based policies or access control lists (ACLs), you can use those policies to grant people access to your resources.

To learn more, consult the following:
+ To learn whether AWS TNB supports these features, see [How AWS TNB works with IAM](security_iam_service-with-iam.md).
+ To learn how to provide access to your resources across AWS accounts that you own, see [Providing access to an IAM user in another AWS account that you own](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_common-scenarios_aws-accounts.html) in the *IAM User Guide*.
+ To learn how to provide access to your resources to third-party AWS accounts, see [Providing access to AWS accounts owned by third parties](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_common-scenarios_third-party.html) in the *IAM User Guide*.
+ To learn how to provide access through identity federation, see [Providing access to externally authenticated users (identity federation)](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_common-scenarios_federated-users.html) in the *IAM User Guide*.

# Compliance validation for AWS TNB
Compliance validation

To learn whether an AWS service is within the scope of specific compliance programs, see [AWS services in Scope by Compliance Program](https://aws.amazon.com/compliance/services-in-scope/) and choose the compliance program that you are interested in. For general information, see [AWS Compliance Programs](https://aws.amazon.com/compliance/programs/).

You can download third-party audit reports using AWS Artifact. For more information, see [Downloading Reports in AWS Artifact](https://docs.aws.amazon.com/artifact/latest/ug/downloading-documents.html).

Your compliance responsibility when using AWS services is determined by the sensitivity of your data, your company's compliance objectives, and applicable laws and regulations. For more information about your compliance responsibility when using AWS services, see [AWS Security Documentation](https://docs.aws.amazon.com/security/).

# Resilience in AWS TNB
Resilience

The AWS global infrastructure is built around AWS Regions and Availability Zones. AWS Regions provide multiple physically separated and isolated Availability Zones, which are connected with low-latency, high-throughput, and highly redundant networking. With Availability Zones, you can design and operate applications and databases that automatically fail over between zones without interruption. Availability Zones are more highly available, fault tolerant, and scalable than traditional single or multiple data center infrastructures. 

For more information about AWS Regions and Availability Zones, see [AWS Global Infrastructure](https://aws.amazon.com/about-aws/global-infrastructure/).

AWS TNB runs your Network Service on EKS clusters in a virtual private cloud (VPC) in the AWS Region that you choose.

# Infrastructure security in AWS TNB
Infrastructure security

As a managed service, AWS Telco Network Builder is protected by AWS global network security. For information about AWS security services and how AWS protects infrastructure, see [AWS Cloud Security](https://aws.amazon.com/security/). To design your AWS environment using the best practices for infrastructure security, see [Infrastructure Protection](https://docs.aws.amazon.com/wellarchitected/latest/security-pillar/infrastructure-protection.html) in *Security Pillar AWS Well‐Architected Framework*.

You use AWS published API calls to access AWS TNB through the network. Clients must support the following:
+ Transport Layer Security (TLS). We require TLS 1.2 and recommend TLS 1.3.
+ Cipher suites with perfect forward secrecy (PFS) such as DHE (Ephemeral Diffie-Hellman) or ECDHE (Elliptic Curve Ephemeral Diffie-Hellman). Most modern systems such as Java 7 and later support these modes.

Here are some examples of shared responsibilities:
+ AWS is responsible for securing components that support AWS TNB, including:
  + Compute instances (also known as *workers*)
  + Internal databases
  + Network communications between internal components
  + The AWS TNB application programming interface (API)
  + AWS Software Development Kits (SDK)
+ You are responsible for securing your access to your AWS resources and your workload components, including (but not limited to):
  + IAM users, groups, roles, and policies
  + S3 buckets that you use to store your data for AWS TNB
  + Other AWS services and resources that you use to support the network service that you provisioned through AWS TNB
  + Your application code
  + Connections between the network service that you provisioned through AWS TNB and its clients

**Important**  
You are responsible for implementing a disaster recovery plan that can effectively recover a network service that you provisioned through AWS TNB.

## Network connectivity security model


The network services that you provision through AWS TNB, run on compute instances within a virtual private cloud (VPC) located in an AWS Region that you select. A VPC is a virtual network in the AWS Cloud, which isolates infrastructure by workload or organizational entity. Communication between compute instances within VPCs stay within the AWS network and don't travel over the internet. Some internal service communication crosses the internet, and is encrypted. Network services provisioned through AWS TNB for all customers running in the same Region share the same VPC. Network services provisioned through AWS TNB for different customers use separate compute instances within the same VPC.

Communications between your network service clients and your network service in AWS TNB traverse the internet. AWS TNB does not manage these connections. It is your responsibility to secure your client connections.

Your connections to AWS TNB through the AWS Management Console, AWS Command Line Interface (AWS CLI), and AWS SDKs are encrypted.

# IMDS version
IMDS version

AWS TNB supports instances that leverage Instance Metadata Service version 2 (IMDSv2), a session-oriented method. IMDSv2 includes higher security than IMDSV1. For more information, see [Add defense in depth against open firewalls, reverse proxies, and SSRF vulnerabilities with enhancements to the Amazon EC2 Instance Metadata Service](https://aws.amazon.com/blogs/security/defense-in-depth-open-firewalls-reverse-proxies-ssrf-vulnerabilities-ec2-instance-metadata-service/).

When launching your instance, you must use IMDSv2. For more information on IMDSv2, see [Use IMDSv2](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/configuring-instance-metadata-service.html) in the *Amazon EC2 User Guide*.
