🛰️ NetVuS - Network Vulnerability Scanner

Scan smart. Stay secure.

NetVuS is a lightweight, Python-based vulnerability scanner designed to quickly assess open ports and associated risks on a target host. Built for budding security analysts and networking students, it bridges the gap between practical skill-building and real-world reconnaissance techniques.

🔍 Features

• Fast TCP port scanning using nmap or socket

• Risk hints for exposed services (e.g., FTP, SSH, HTTP)

• Custom target + port range input

• Command-line interface for flexible scanning

• Clean and readable scan summary report

• Educational commentary on service risks

🚀 Getting Started

1. Clone the Repo

git clone https://github.com/supunhg/NetVuS_S0004.git
cd netvus

2. Install Requirements

pip install python-nmap
# Ensure nmap is installed and accessible in PATH

3. Run the Scanner

python netvus.py --target 192.168.1.1 --ports 20-1000

⚙️ Example Output

[*] Scanning 192.168.1.1...
[+] Port 22 (SSH) is open – Check for default credentials.
[+] Port 80 (HTTP) is open – Potential exposure to directory listing.
[✓] Scan Complete. 3 open ports detected.

💡 Why NetVuS?

This project helped me sharpen:

• Real-time port scanning logic

• Host discovery + service fingerprinting

• Cyber risk interpretation at the analyst level

• CLI tool design & Python networking modules

It’s a mini blueprint for practical vulnerability reconnaissance — and a strong first step into my cybersecurity analyst journey.
