This CLI python script is designed to be used by security consultants, IT admins and network engineers to do two things, compare two Nmap XML files to create a spreadsheet that compares IPs, ports and services between the files, and create a markdown report using GPT via OpenAI directly or Daniel Miessler's Fabric tool.

• Multiple File Support: Parse and analyze two Nmap XML output files.
• Structured Data: Converts Nmap's XML output into a structured format for further processing.

• Change Detection: Compare results from two Nmap scans to identify new, altered, or removed services and ports. Useful for when you scan the same IPs from different source IPs or over time.
• Excel Reporting: Automatically generates detailed Excel spreadsheets with the comparison results and some stats.

• Network Exposure Statistics: Offers statistical analysis on detected services and open ports.
• Excel Visualizations: Includes pie charts in Excel reports for a graphical representation of the network's security posture.

• GPT Report Generation: Uses OpenAI's GPT to generate insightful analysis reports based on Nmap result stats. The tool uses a hardcoded prompt that sets the tone and requirements, then the script inserts the stats (no identifying information is provided) and if -c --context has been provided, it'll add the context to the bottom of the prompt.
• Customizable Context: Enhance GPT analysis by providing additional context, tailoring the report to specific needs.

• Fabric Report Generation: Uses Fabric to generate insightful analysis reports based on Nmap result stats. The tool uses a hardcoded system prompt (pattern) that sets the tone and requirements, then the script inserts the stats (no identifying information is provided). I prefer the output created by Fabric over GPT.

The script prints the help page if no args are passed, or you can access with python nmap-analysis.py -h. Make sure to create an .env file that contains "OPENAI_KEY=x"

• Comparing Nmap Scans:

python nmap-analysis.py compare -ff (--first-nmap-file) path/to/first.xml -lf (--last-nmap-file) path/to/second.xml

Generating a GPT Report:

python nmap-analysis.py gpt-report -gf (--gpt-nmap-file) path/to/nmap.xml -c (--context) "Your optional context here"

Generating a AI Report via Fabric (uses your chosen model and vendor):

python nmap-analysis.py fabric-report -gf (--gpt-nmap-file) path/to/nmap.xml

• 3.10+ probably (created using 3.12)
• An OpenAI API key for GPT report generation that is set in local env
• Install and configure Fabric
