Nmap Security Scanner - Vulnerability Analysis

Overview

This project utilizes Nmap (Network Mapper) to scan a target network or system for open ports, services, and potential vulnerabilities. The goal is to analyze the security posture of the system and suggest remediation strategies.

Features

  • Performs deep network scanning using Nmap
  • Detects open ports and running services
  • Identifies security vulnerabilities using NSE scripts
  • Generates detailed scan reports
  • Provides security recommendations

Installation

Prerequisites

Ensure you have Nmap installed on your system:

Linux / macOS:

sudo apt install nmap  # Debian-based
sudo dnf install nmap  # Fedora-based
brew install nmap      # macOS

Windows:

Download and install Nmap from nmap.org.

Usage

1. Basic Port Scan

nmap <target-ip>

2. Scan for Vulnerabilities

nmap --script=vuln <target-ip>

3. Perform a Full Scan and Save Results

nmap -A -p- -oN scan_results.txt <target-ip>

4. Scan Multiple Hosts

nmap -iL targets.txt -oN scan_results.txt

Interpreting Results

  • Open Ports: Services running on the system
  • Service Detection: Identifies running software
  • Vulnerabilities: Lists potential security risks

Security Recommendations

  • Close unnecessary ports
  • Update outdated software/services
  • Implement firewalls and access controls
  • Regularly monitor network activity

Reporting Issues

If you find a vulnerability, report it responsibly to the system owner or administrator.
