The Czech Republic top-level domain registrar, CZ.NIC, wondered about the safety of homerouters, so it set out to gather some information on the prevalence ofattacks against them. It turns out that one good way to do that is tocreate a home router that logs statistics and other information.Michal HruAecki from CZ.NIC came to the 2019 Southern CaliforniaLinux Expo (SCALE 17x) in Pasadena, CA to describe the experiment and how it grew intoa larger project that makes and sells open-source routers.
