Survey the topic of computer network mapping using both active (e.g., scanning) and passive (e.g., network traffic monitoring) methods. Review available passive methods and tools for mapping computer networks, ranging from listing active devices and open ports through fingerprinting to detecting criticality and functional dependencies between services. Design and implement a framework that integrates existing passive monitoring tools and enables comprehensive mapping of a computer network. The user will define the address range and provide input data (e.g., PCAP or NetFlow) and the framework will extract the information on the communicating hosts and the network. The results will be presented in comprehensive visualizations for human readers and be ready for export to machine-readable data formats. Consider implementing the framework as a Jupyter Notebook or similar interactive solution that would enable smooth integration of additional analytical components and human interaction.
