Installation: Getting Shuffler Up and Running

Installing Shuffler can be done in a few ways, but using Docker and Docker Compose is generally the easiest and recommended approach. This ensures a consistent environment and simplifies the setup process.

Prerequisites

Before you begin, ensure that you have the following installed:

• Docker
• Docker Compose

You can download and install Docker and Docker Compose from the official Docker website: https://docs.docker.com/get-docker/

Installation Steps

1. Clone the Shuffler Repository: Start by cloning the official Shuffler repository from GitHub. This repository contains the necessary Docker Compose file and other configuration files.

   git clone https://github.com/Shuffle-Team/Shuffle.git
   cd Shuffle
   

2. Configure the Environment: The repository comes with a `docker-compose.yml` file that defines the services required to run Shuffler. You might need to configure environment variables, such as database credentials or API keys. Create a `.env` file in the same directory as `docker-compose.yml` and populate it with the necessary variables. A sample `.env` file might look like this:

   
   POSTGRES_USER=shuffler
   POSTGRES_PASSWORD=your_strong_password
   POSTGRES_DB=shufflerdb
   

   Important: Replace `your_strong_password` with a secure password.

3. Start Shuffler with Docker Compose: Use Docker Compose to start all the Shuffler services defined in the `docker-compose.yml` file.

   docker-compose up -d
   

   The `-d` flag runs the services in detached mode (in the background).

4. Access Shuffler: Once the services are up and running, you can access the Shuffler web interface by navigating to `http://localhost:8000` in your web browser.
5. Initial Setup: The first time you access Shuffler, you will be prompted to create an admin user. Follow the on-screen instructions to set up your account.

Usage: Building and Executing Automated Workflows

Once Shuffler is installed, the real power comes from creating and executing automated workflows. Here’s a step-by-step example of creating a simple workflow that responds to a suspicious IP address:

1. Log in to Shuffler: Access the Shuffler web interface and log in with the admin user you created during the installation.
2. Create a New Workflow: Click on the “Workflows” tab in the left-hand navigation menu and then click the “Create Workflow” button. Give your workflow a descriptive name, such as “Investigate Suspicious IP”.
3. Add a Trigger: Workflows need a trigger to start. In this case, we’ll use a manual trigger, which allows you to manually input an IP address. Add a “Manual Trigger” applet to the workflow canvas. Configure the trigger to accept an IP address as input.
4. Add an Applet to Get Geo Location Information: Add an Applet from the left menu which will resolve a Geolocation from the suspicious IP Address. You can accomplish this by adding the “IPinfo” applet. Configure the “IPinfo” applet with an API key from IPinfo (you’ll need to create a free account on IPinfo). Connect the output of the manual trigger (the IP address) to the input of the IPinfo applet.
5. Add an Applet to Check if the IP is on a blocklist: You may want to determine if the IP is present on a threat feed such as VirusTotal. Add the VirusTotal Applet and associate it with the IP value.
6. Add a Decision Applet: Now, add a “Decision” applet to evaluate the information retrieved from the GeoIP and VirusTotal lookups. Configure the decision logic to check if the IP address is located in a high-risk country or if it’s listed on a known threat feed. For example, you might check if the country code from IPinfo is in a list of countries you consider high-risk, or if the VirusTotal results indicate a high detection ratio.
7. Add Actions Based on the Decision: Based on the decision, you can add different actions. For example:
   • If the IP is suspicious: Add an applet to create a ticket in your ticketing system (e.g., Jira, ServiceNow), send an email notification to the security team, and block the IP address on your firewall (using the appropriate firewall applet).
   • If the IP is not suspicious: Add an applet to log the event and send a notification indicating that the IP was investigated and found to be benign.
8. Connect the Applets: Draw lines to connect the applets, ensuring the flow of data from the trigger to the various applets and actions.
9. Save and Test the Workflow: Save the workflow and then click the “Run” button to test it. Enter a suspicious IP address in the manual trigger and observe the workflow execution. Verify that the actions are performed correctly based on the decision logic.

This is a simple example, but it illustrates the basic principles of building workflows in Shuffler. You can create more complex workflows by adding more applets, decision points, and actions to address a wide range of security scenarios.

Example workflow execution:

{
  "input": "8.8.8.8",
  "geoip": {
    "ip": "8.8.8.8",
    "city": "Mountain View",
    "region": "California",
    "country": "US",
    "loc": "37.4056,-122.0775",
    "org": "AS15169 Google LLC",
    "postal": "94043",
    "timezone": "America/Los_Angeles"
  },
  "virustotal": {
    "data": {
      "attributes": {
        "last_analysis_stats": {
          "malicious": 0,
          "suspicious": 0,
          "undetected": 0,
          "harmless": 0
        }
      }
    }
  }
}
