Using aws inspector2 with appstream

Question

Pulumi · Accepted Answer

To use AWS Inspector2 with AppStream, you will need to set up an application streaming environment with AppStream and integrate it with AWS Inspector2 for security assessment. Below is a Pulumi program in TypeScript that outlines the essential steps to achieve this setup.

Let's break down the process into the following steps:
1. Create an AppStream Stack and Fleet.
2. Set up the AWS Inspector2 configuration.
3. Associate AppStream with AWS Inspector2 for security assessments.

Here is a detailed explanation and the Pulumi program for the setup:

### 1. Create an AppStream Stack and Fleet
Firstly, you create an AppStream stack. A stack consists of a fleet of streaming instances and optionally, associated storage. You define user settings and deploy applications to the stack.

Next, you create an AppStream fleet, which is a collection of streaming instances that run the applications your users access. You associate this fleet with the stack you created earlier.

```typescript
import * as pulumi from "@pulumi/pulumi";
import * as aws from "@pulumi/aws";

// Create an AppStream Stack
const appStreamStack = new aws.appstream.Stack("myAppStreamStack", {
    // Stack properties go here
    // Reference: https://www.pulumi.com/registry/packages/aws/api-docs/appstream/stack
    name: "MyAppStreamStack",
});

// Create an AppStream Fleet associated with the Stack
const appStreamFleet = new aws.appstream.Fleet("myAppStreamFleet", {
    // Fleet properties go here
    // Reference: https://www.pulumi.com/registry/packages/aws/api-docs/appstream/fleet
    name: "MyAppStreamFleet",
    instanceType: "stream.standard.medium",
    imageName: "SampleImage",
    fleetType: "ALWAYS_ON",
    streamView: "APP",
    iamRoleArn: "arn:aws:iam::123456789012:role/AppStreamImageBuilder",
    // Associating the fleet to the stack
    computeCapacity: {
        desiredInstances: 1,
    },
    enableDefaultInternetAccess: true,
});

// Associate the Fleet with the Stack
const fleetStackAssociation = new aws.appstream.StackFleetAssociation("myFleetStackAssociation", {
    fleetName: appStreamFleet.name,
    stackName: appStreamStack.name,
});
```

### 2. Set Up the AWS Inspector2 Configuration
This involves enabling Inspector2 for the AWS account and specifying resource assessment configurations. Inspector2 helps you to automatically discover and scan AWS workloads for software vulnerabilities and unintended network exposure.

```typescript
import * as inspector from "@pulumi/aws/inspector";

// Enable AWS Inspector2
const inspectorConfig = new inspector.AssessmentTemplate("myInspectorTemplate", {
    // Configurations for AWS Inspector2
    // Reference: https://www.pulumi.com/registry/packages/aws/api-docs/inspector2/memberassociation
    // The configurations will be specific to your AWS account and requirements.
});
```

### 3. Associate AppStream with AWS Inspector2 for Security Assessments
You typically ensure that the instances in your AppStream fleet adhere to your security posture as defined by AWS Inspector2. Currently, there isn't a direct Pulumi AWS resource for associating Inspector with AppStream. The association typically takes place via AWS Identity and Access Management (IAM) roles and policies that allow Inspector2 to scan instances of the AppStream fleet.

```typescript
// IAM Role for Inspector2 to scan AppStream fleet instances
const inspectorRole = new aws.iam.Role("myInspectorRole", {
    assumeRolePolicy: {
        Version: "2012-10-17",
        Statement: [{
            Action: "sts:AssumeRole",
            Effect: "Allow",
            Principal: {
                Service: "inspector.amazonaws.com",
            },
        }],
    },
    // Add policies that allow Inspector to access and assess AppStream resources
});

// Policy attachment granting Inspector necessary permissions
const policyAttachment = new aws.iam.RolePolicyAttachment("myPolicyAttachment", {
    role: inspectorRole.name,
    policyArn: aws.iam.ManagedPolicy.AmazonInspectorFullAccess,
});
```

The Pulumi program above does not directly associate AWS Inspector2 with AppStream due to the lack of a direct integration resource. However, it shows how you could create IAM roles and managed policies to allow Inspector2 access for resource scanning. This IAM role would be attached to the AppStream environment and configured to interact with Inspector2, assuming your AWS environment supports this setup.

Ensure you replace placeholders (like IAM role ARNs and image names) with actual values from your AWS account. Please note that AWS services configuration can be complex depending on your specific use case, and it often requires adjustments to policies and service settings.

Remember to refer to the official AWS documentation for specifics on setting up Inspector2 and AppStream and the Pulumi AWS package documentation for additional details on the resources used.
