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.
