Configuring Netsparker Enterprise for Amazon Web Services

Netsparker Enterprise can be configured to run scanner agents on Amazon Web Services (AWS). When you launch a new scan, Netsparker Enterprise will create a new instance for the target scan and terminate it automatically once the scan is completed.

For further information Cloud Provider Settings.

AWS Configuration

First, you need to install and configure the scanner agent on an EC2 instance and then create a machine image (AMI) to use it as a base instance.

Each stage of this process is outlined below:

  1. Selecting a Region
  2. Creating S3 Buckets
  3. Creating IAM Users
  4. Creating an AMI for the Scanner Agent
  5. Configuring Netsparker Enterprise

Selecting a Region

Netsparker Enterprise uses AWS S3 buckets for object storage and EC2 service for launching new instances.

S3 and EC2 resources need to be in the same AWS region. For that reason, please choose an AWS region and create all resources in that region.

How to Select a Region

For information on how to select a region, see Amazon's EMR documentation, Choose an AWS Region.

Creating S3 Buckets

Netsparker Enterprise needs three different buckets to store scan data.

How to Create S3 Buckets

  1. Open the AWS console and navigate to the S3 service.
  2. Create 3 buckets for raw scan data, screenshots and customizations. For example, you can use bucket names like this:
    • exampleinc.ne.scandata (for raw scan data)
    • exampleinc.ne.scanscreenshots (for form authentication screenshots)
    • exampleinc.ne.customizations (for customizations)

Creating IAM Users

Next, you must create IAM Users.

How to Create an Access Policy for the Web Application

  1. Go to AWS console and navigate to the IAM service.
  2. Click Policies.
  3. Click Create Your Own Policy.
  4. Enter a policy name (e.g. NEWebAppPolicy).
  5. Enter your bucket names in the policy template code below and paste it into the Policy Document field.
{
"Version": "2012-10-17",
"Statement": [
{
"Action": [
"s3:*"
],
"Effect": "Allow",
"Resource": [
"arn:aws:s3:::ENTER_SCAN_DATA_BUCKET_NAME/*",
"arn:aws:s3:::ENTER_SCREENSHOTS_BUCKET_NAME/*",
"arn:aws:s3:::ENTER_CUSTOMIZATIONS_BUCKET_NAME/*"
]
},
{
"Action": [
"ec2:CreateTags",
"ec2:DeleteTags",
"ec2:DescribeInstances",
"ec2:RunInstances",
"ec2:TerminateInstances"
],
"Effect": "Allow",
"Resource": [
"*"
]
}
]
}

      6. Click Create Policy.

How to Create an Access Policy for the Scanner Agent

Creating an AMI for the Scanner Agent

There are three steps to this process:

  1. Launching an Instance for the Scanner Agent
  2. Configuring the Scanner Agent Instance
  3. Creating a Scanner Agent Image

Launching an Instance for the Scanner Agent

First, you need to launch an instance for a Scanner Agent.

How to Launch an Instance for a Scanner Agent

  1. Navigate to the EC2 service.
  2. From the main menu, click Instances
  3. Click Launch Instance.
  4. Select Microsoft Windows Server 2019 Base as the AMI.

  1. Click Choose Instance Type and select an Instance Type (c4.large is recommended).

  1. Click Configure Instance.
  2. Set the Auto-assign Public IP dropdown to Enable. (This is needed for RDP connections.)

  1. Click Next: Add Storage and set the Disk Size (a minimum of 30 GB is  recommended).
  2. Click Next: Add Tags.
  3. Click Next: Configure Security Group.
  4. Click Review and Launch.

Configuring the Scanner Agent Instance

Next, you need to install the Netsparker Scanner Agent to the target EX2 instance.

How to Configure a Scanner Agent Instance

  1. Navigate to the EC2 service.
  2. From the main menu, click Instances.
  3. Right click the previously launched scanner agent instance, and click Connect.

    1. Connect to your instance with the supplied RDP information.
    2. Ensure that you can connect to your on-premises Netsparker Enterprise web application from this instance.
    3. Download and extract NetsparkerEnterprise.zip AgentSetup.exe into your instance
    4. Run AgentSetup.exe and install the scanner agent. Enter the required information asked by the agent installation wizard. For API Token, navigate to the Configure New Agent page by clicking Agents > Manage Agents > Configure New Agent.

8. Start a command prompt and type: cd C:\Program Files (x86)\Netsparker Cloud Agent.

  1. By default, the scanner agent is not configured to run in AWS. Enter this command to uninstall the scanner agent's Windows service: Netsparker.Cloud.Agent.exe /u.

    1. Open the agent’s configuration file with a text editor: C:\Program Files (x86)\Netsparker Cloud Agent \Netsparker.Cloud.Agent.exe.config.
    2. Navigate to the <netsparker> section and set agentType to Cloud.

12. Save the Netsparker.Cloud.Agent.exe.config file.

13. Type this command to re-install scanner agent windows service: Netsparker.Cloud.Agent.exe /i.

  1. The installed agent's Windows Service’s Startup Type will be 'Manual' (it must stay that way).
  2. Open a PowerShell command window and run the following command: C:\ProgramData\Amazon\EC2-Windows\Launch\Scripts\InitializeInstance.ps1 –Schedule

Creating a Scanner Agent Image

Next, you need to create an AMI that will be used as a base image for new scans.

How to Create a Scanner Agent Image

  1. Open the EC2 instances page on the AWS console.
  2. Select the EC2 instance and from the Actions menu click Instance State > Stop/ Wait for the agent instance to be stopped.
  3. Once the agent instance has stopped, right click on it, and click Create Image. Enter a name for your image and click Create Image.

  1. Navigate to the AMIs page and save your AMI ID (you will need it later).

Configuring Netsparker Enterprise

Next, you need to configure your AWS settings.

How to Configure the Netsparker Enterprise Web Application

  1. Make an RDP connection to your Netsparker Enterprise web application server.
  2. Log in to Netsparker Enterprise.
  3. From the main menu, click Settings then Cloud Provider.
  4. Enter your AWS settings. (The Deployment Bucket Name field is not required. You can enter a dummy value.)
    • You can find the settings for the Instance Type, Subnet ID and Key Pair Name in your stopped instance’s details in AWS.
    • Click Security Group to get the Security Group id (e.g. sg-abc3fec2).

  1. You can now run new scans on your AWS environment.
