Seeking to minimize Internet’s susceptibility to spoofed DDoS attacks, we are developing and supporting open-source software tools to assess and report on the deployment of source address validation (SAV) best anti-spoofing practices. This project includes applied research, software development, new data analytics, systems integration, operations and maintenance, and an interactive analysis and reporting service.
We generate a summary report on the current “state” of Internet IP source address spoofing/filtering using data from an active measurement tool. Since 2015 when UCSD/CAIDA took over development and support of the spoofer infrastructure, we’ve collected data from 7468 autonomous systems in 207 countries. More details and published results from our research are also available. The CAIDA IP Spoofer report is highlighted by ShadowServer.
