Shuffler is more than just another SOAR platform; it’s a flexible, community-driven project designed to empower security teams. It allows you to create automated workflows, called “Shuffles,” that connect various security tools and data sources. Imagine automatically enriching threat intelligence data, isolating infected systems, and notifying stakeholders – all triggered by a single alert. That’s the power of Shuffler.

What makes Shuffler ingenious is its visual workflow editor. You don’t need to be a coding expert to build complex automation scenarios. The drag-and-drop interface makes it easy to connect different “Apps” (integrations with other security tools) and define the flow of data and actions. This low-code approach democratizes security automation, enabling more team members to contribute to building and maintaining robust incident response processes.

Furthermore, Shuffler’s open-source nature fosters collaboration and innovation. The community actively contributes new Apps, improvements, and best practices, ensuring that the platform remains adaptable and relevant in the face of emerging threats.

2. Installation: Getting Started with Shuffler

Installing Shuffler can be done in various ways, depending on your environment and preferences. Here, we’ll cover the most common methods:

2.1. Docker Compose (Recommended)

Docker Compose provides a simple and reproducible way to deploy Shuffler and its dependencies. This is the recommended method for most users.

  1. Install Docker and Docker Compose: Ensure you have Docker and Docker Compose installed on your system. Refer to the official Docker documentation for installation instructions specific to your operating system.
  2. Download the Docker Compose file: You can download a pre-configured `docker-compose.yml` file from the Shuffler GitHub repository or create your own. A basic example is shown below:
    3. 
version: "3.8"
services:
  shuffler:
    image: shuffleautomation/shuffler:latest
    ports:
      - "8000:8000"
    environment:
      - APP_SECRET=your_secret_key # Change this!
      - DATABASE_URL=postgresql://shuffler:password@db:5432/shuffler
    depends_on:
      - db
    restart: always

  db:
    image: postgres:14
    environment:
      - POSTGRES_USER=shuffler
      - POSTGRES_PASSWORD=password
      - POSTGRES_DB=shuffler
    volumes:
      - shuffler_db:/var/lib/postgresql/data
    restart: always

volumes:
  shuffler_db:
  3. Configure the environment: Replace `your_secret_key` in the `docker-compose.yml` file with a strong, randomly generated secret. This is crucial for security. You can also adjust the database credentials if needed.
  4. Start Shuffler: Navigate to the directory containing your `docker-compose.yml` file in your terminal and run: 
    docker-compose up -d

    This command will download the necessary images and start the Shuffler containers in detached mode.

  5. Access Shuffler: Open your web browser and navigate to `http://localhost:8000`. You should see the Shuffler login page. The default credentials are `admin:password`. **Change these immediately after logging in for the first time!**

2.2. Kubernetes

For larger deployments, Kubernetes offers scalability and resilience. Deploying Shuffler to Kubernetes involves creating Kubernetes manifests for the Shuffler deployment, service, and persistent volume claims.

While a detailed Kubernetes deployment guide is beyond the scope of this article, here’s a high-level overview:

  1. Create Kubernetes manifests: Define the Shuffler deployment, service, and persistent volume claims using YAML files. These files will specify the container image, resource requests, and other configuration parameters.
  2. Apply the manifests: Use the `kubectl apply -f ` command to deploy Shuffler to your Kubernetes cluster.
  3. Configure Ingress (Optional): If you want to access Shuffler from outside the cluster, you’ll need to configure an Ingress resource to route traffic to the Shuffler service.

Refer to the Shuffler documentation and Kubernetes documentation for more detailed instructions on Kubernetes deployments.

2.3. Manual Installation

While not recommended for most users, you can also install Shuffler manually. This requires more technical expertise and is suitable for advanced users who need fine-grained control over the installation process. Detailed instructions can be found on the Shuffler Github page

3. Usage: Building Your First Shuffler Workflow

Now that you have Shuffler installed, let’s create a simple workflow to demonstrate its capabilities. We’ll build a Shuffle that takes an IP address as input and enriches it with threat intelligence data from VirusTotal.

  1. Log in to Shuffler: Access the Shuffler web interface using the credentials you configured during installation.
  2. Create a new Shuffle: Click on the “Shuffles” tab and then click the “Create Shuffle” button. Give your Shuffle a name (e.g., “IP Enrichment”) and a description.
  3. Add an Input Node: Drag an “Input” node from the left-hand sidebar onto the canvas. Configure the input node to accept an IP address as input. Set the “Data Type” to “IP Address.”
  4. Add a VirusTotal App: Search for the “VirusTotal” App in the sidebar and drag it onto the canvas.
    • Configure VirusTotal App: You’ll need a VirusTotal API key to use this App. Obtain a free API key from VirusTotal and enter it in the App’s configuration.
    • Connect the Nodes: Connect the output of the Input node to the input of the VirusTotal App. This will pass the IP address to VirusTotal for analysis.
  5. Add a Data Transformation Node (Optional): Often, the output from an App needs to be transformed to be more easily readable or used by subsequent Apps. Add a “Data Transformation” node to parse the JSON response from VirusTotal and extract the relevant information. You can use JavaScript or other scripting languages to perform the transformation.
  6. Add an Output Node: Drag an “Output” node onto the canvas and connect it to the output of the VirusTotal App (or the Data Transformation node, if you added one). Configure the output node to display the enriched IP address information.
  7. Save the Shuffle: Click the “Save” button to save your workflow.
  8. Run the Shuffle: Click the “Run” button to execute the Shuffle. Enter an IP address in the input field and click “Execute.” The output node will display the threat intelligence data from VirusTotal.

This is a simple example, but it demonstrates the basic principles of building Shuffler workflows. You can expand on this by adding more Apps, data transformations, and conditional logic to create more sophisticated automation scenarios.
