Python Network Port Analyzer

Project Overview

This independent cybersecurity portfolio project demonstrates how Python can review fictional network port-scan results, identify commonly exposed services, and prioritize findings for analyst review.

This project analyzes supplied scan data only. It does not scan or probe live systems.

Skills Demonstrated

• Python
• Network security fundamentals
• TCP port and service analysis
• JSON parsing
• Conditional logic
• Risk classification
• Security automation
• Analyst reporting

Project Files

• port_analyzer.py — Main Python analysis script
• sample_scan.json — Fictional network scan results
• port_analysis_report.txt — Example generated report
• requirements.txt — Dependency notes

Analysis Rules

The script reviews open ports and identifies common services such as SSH, Telnet, HTTP, HTTPS, SMB, RDP, and database services. It assigns a review priority based on simple defensive rules.

Run the Project

python3 port_analyzer.py

Cybersecurity Relevance

Open ports can expose network services to users or systems that can reach them. Security analysts review service exposure to identify unnecessary access, legacy protocols, administrative services, and systems that may require additional hardening.

Portfolio Note

This is an independent cybersecurity portfolio project for educational and professional demonstration. All hosts and scan data are fictional/reserved examples. The script performs offline analysis and does not conduct network scanning.

Future Improvements

• CSV report export
• Configurable approved-port baselines
• Asset criticality scoring
• Comparison of scans over time
• Service-version fields
• Integration with authorized vulnerability-management workflows
