🛡️ Network Vulnerability Scanner

📌 Overview

A simple Python-based network vulnerability scanner that checks a target host for open TCP ports in the range 1–1025.
This project was developed as part of my Cybersecurity Bootcamp to practice Python scripting, socket programming, and network vulnerability assessment.

🚀 How to Use

1. Run with a target host (preferred):

python scanner.py 192.168.1.10

2. Or run interactively (you will be prompted for a host):

python scanner.py

3. Optional flags:

python scanner.py 192.168.1.10 --start 20 --end 443 --timeout 0.2 --outfile MyScan.txt

The script scans TCP ports in the specified range (default 1–1024), prints open ports, and writes results to the file ScanResults (or your chosen --outfile).

⚠️ Use only on systems you own or have written permission to test.
