## 🚀 Installation & Setup

### Prerequisites

Before running this visualization, you'll need:

1. **Node.js** (v16 or higher)
   - Download from: https://nodejs.org/
   - Verify installation: `node --version`

2. **npm** (comes with Node.js)
   - Verify installation: `npm --version`

3. **Git** (to clone the repository)
   - Download from: https://git-scm.com/
   - Verify installation: `git --version`

### Step-by-Step Installation

```bash
# 1. Clone the repository
git clone https://github.com/ahays248/VT_Viz.git
cd VT_Viz

# 2. Install dependencies
npm install

# 3. Generate attack data (optional - data is pre-generated)
npm run generate-data

# 4. Start the development server
npm run dev
```

The visualization will open automatically at `http://localhost:3000/` (or port 3001 if 3000 is in use).

### Quick Start (Copy & Paste)

```bash
# One-line setup for experienced users
git clone https://github.com/ahays248/VT_Viz.git && cd VT_Viz && npm install && npm run dev
```

### Building for Production

```bash
# Create optimized production build
npm run build

# Preview production build locally
npm run preview
```

The production build will be in the `dist/` folder, ready for deployment to any static hosting service.

### Troubleshooting Installation

**Port already in use:**
- The dev server will automatically try port 3001 if 3000 is busy
- Or manually specify: `npm run dev -- --port 3002`

**npm install fails:**
```bash
# Clear npm cache and retry
npm cache clean --force
rm -rf node_modules package-lock.json
npm install
```

**Visualization doesn't load:**
- Check browser console for errors (F12)
- Ensure WebGL is enabled in your browser
- Try Chrome, Firefox, or Edge (latest versions)

### System Requirements

- **Minimum:** 4GB RAM, modern browser with WebGL support
- **Recommended:** 8GB RAM, dedicated graphics card
- **Browsers:** Chrome 90+, Firefox 88+, Edge 90+, Safari 14+

- Industrial control logic

### Potential Consequences
- **Water Systems**: Chemical balance manipulation
- **Power Grid**: Substation disruption
- **Industrial**: Equipment destruction
- **Communications**: Network outages

## 🛡️ Defense Recommendations

1. **Patch Management**: Apply Versa Director updates immediately (CVE-2024-39717)
2. **Network Segmentation**: Isolate OT from IT networks
3. **MFA**: Require for all administrative access
4. **Monitoring**: Watch for LOTL techniques (PowerShell, WMI, RDP)
5. **Logging**: Centralize and protect event logs (attackers clear logs)
6. **Port Security**: Block port 4566 from internet access
7. **Webshell Detection**: Check /var/versa/vnms/web/custom_logo/ for VersaMem shells
