# Configuring AWS Verified Access for ZTNA

## Overview

AWS Verified Access is a Zero Trust Network Access (ZTNA) service that provides secure, VPN-less access to corporate applications hosted in AWS. It evaluates each access request in real-time against granular conditional access policies written in the Cedar policy language, ensuring access is granted per-application only when specific security requirements such as user identity and device security posture are met and maintained. Verified Access integrates with AWS IAM Identity Center, third-party identity providers (Okta, CrowdStrike, JumpCloud, Jamf), and device management solutions. For multi-account deployments, AWS Resource Access Manager (RAM) enables sharing Verified Access groups across organizational units.


## When to Use

- When deploying or configuring configuring aws verified access for ztna capabilities in your environment
- When establishing security controls aligned to compliance requirements
- When building or improving security architecture for this domain
- When conducting security assessments that require this implementation

## Prerequisites

- AWS account with appropriate IAM permissions
- Identity provider (AWS IAM Identity Center, Okta, or OIDC-compatible)
- Device trust provider (CrowdStrike, Jamf, JumpCloud, or AWS Verified Access native)
- Internal Application Load Balancer (ALB) or network interface endpoint
- Understanding of Cedar policy language
- VPC with application workloads to protect

## Core Components

### Verified Access Instance

The regional entity that evaluates access requests against policies.

```bash
# Create Verified Access Instance via AWS CLI
aws ec2 create-verified-access-instance \
  --description "Production Zero Trust Instance" \
  --tag-specifications 'ResourceType=verified-access-instance,Tags=[{Key=Environment,Value=production}]'
```

### Trust Providers

#### Identity Trust Provider (AWS IAM Identity Center)

```bash
# Create identity trust provider
aws ec2 create-verified-access-trust-provider \
  --trust-provider-type user \
  --user-trust-provider-type iam-identity-center \
  --policy-reference-name "idc" \
  --description "IAM Identity Center trust provider" \
  --tag-specifications 'ResourceType=verified-access-trust-provider,Tags=[{Key=Type,Value=identity}]'
```

#### Identity Trust Provider (OIDC - Okta)

```bash
aws ec2 create-verified-access-trust-provider \
  --trust-provider-type user \
  --user-trust-provider-type oidc \
  --oidc-options '{
    "Issuer": "https://company.okta.com/oauth2/default",
    "AuthorizationEndpoint": "https://company.okta.com/oauth2/default/v1/authorize",
    "TokenEndpoint": "https://company.okta.com/oauth2/default/v1/token",
    "UserInfoEndpoint": "https://company.okta.com/oauth2/default/v1/userinfo",
    "ClientId": "0oa1234567890",
    "ClientSecret": "client-secret-here",
    "Scope": "openid profile groups"
  }' \
  --policy-reference-name "okta" \
  --description "Okta OIDC trust provider"
```

#### Device Trust Provider (CrowdStrike)

```bash
aws ec2 create-verified-access-trust-provider \
  --trust-provider-type device \
  --device-trust-provider-type crowdstrike \
  --device-options '{
    "TenantId": "crowdstrike-tenant-id",
    "PublicSigningKeyUrl": "https://api.crowdstrike.com/zero-trust/v2/certificates"
  }' \
  --policy-reference-name "crowdstrike" \
