Fire-Wall-Dos-Python

This project detects and mitigates Denial-of-Service (DoS) attacks using Python and Scapy. It includes:

• DoS Blocker (detects & blocks high-rate traffic and Nimda worm signatures).

• DoS Flooder (simulates a flood attack).

• Nimda Worm Packet (sends a malicious request to test detection).

• 📌 Its Features

• IP Whitelist & Blacklist , Explicitly allow or deny certain IPs.

• Packet Rate Limiting , Blocks sources sending too many packets per second.

• Signature Detection , Identifies known attack payloads.

• Logging System , Records all blocked IPs and events.

• Persistent iptables Rules , Ensures blocked IPs stay blocked after reboot.

• 🚀 Setup & How to use
