Abstract
A network telescope, also known as darknet, is a passive monitoring system designed to collect unsolicited traffic directed to unused IPv4 address space. This tool provides valuable insights into large-scale cybersecurity threats, scanning patterns, and trends in Internet traffic. In this work, we explore the implementation of a network telescope that leverages cloud providers’ IP addresses rather than generic public IPs, as commonly done in several related works. The objective is to highlight the advantages of using cloud-owned addresses, e.g., increased visibility or unique traffic sources. To this end, we first compared the services offered by major cloud providers and selected the most suitable option.
We then monitored 256 cloud-owned IP addresses over a one-month period to maximize the coverage of our analysis
