DexFortify is a high-fidelity, interactive network topology simulator and laboratory designed to teach the fundamentals of network security through real-time visualization. It allows users to defend a simulated infrastructure against automated attacks by configuring firewalls and Intrusion Detection System (IDS) rules.
- Real-Time Traffic Simulation: Visualize packets moving between nodes (Internet, Firewall, DMZ, Internal Servers).
- Interactive Topology: Build and modify your network layout.
- Security Logic Engine:
- Firewall Configuration: Block malicious IPs using source-based filtering.
- Deep Packet Inspection (IDS): Inspect packet payloads and block threats based on keyword patterns.
- Gamified Learning: Scoring systems, combos, and health metrics for critical infrastructure.
- Responsive Design: Fully optimized for desktop and mobile devices.
- Framework: Next.js 15 (App Router)
- Visualization: ReactFlow & Framer Motion
- State Management: Zustand
- Styling: Tailwind CSS & Vanilla CSS (Custom Variable System)
- Icons: Lucide React
- Node.js 18.x or later
- npm or pnpm

Clone the repository:
git clone https://github.com/yourusername/DexFortify.git cd DexFortify -
Install dependencies:
npm install
-
Run the development server:
npm run dev
-
Visit the app: Open http://localhost:3000 in your browser.
- Observe: Watch the incoming traffic. Green dots are benign; red dots are malicious threats.
- Analyze: Click on a malicious packet to see its source IP and payload.
- Defend:
- Use the Firewall panel to block the IP address of known threats.
- Use the IDS panel to block specific keywords found in malicious payloads (e.g., "sql_inject", "backdoor").
- Survive: Prevent threats from reaching your internal servers. If a server's health hits zero, the mission fails.
