## 🌐 Example Scenarios

📌 **Malware Analysis**: Use INetSim to analyze how malware interacts with different network services by simulating its command and control (C2) server.

📌 **Network Security Testing**: Test how your firewall, IDS, or IPS reacts to simulated internet traffic.

📌 **Forensic Investigations**: Replay network activity in a lab environment without exposing real systems.

## 🚀 Pro Tips

💡 Use `iptables` to redirect traffic to INetSim for seamless analysis.
```bash
iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT --to-port 80
```

💡 Customize responses by editing `/etc/inetsim/inetsim.conf`.

💡 Run INetSim in a sandboxed environment like a VM to avoid unintended network exposure.
