Cyberskills at ITU: Internet Security
DK Hostmaster is a tiny company that runs an even tinier, but crucial, part of the Danish Internet. Without DNS there would not be an Internet as we know it. The Domain Name System builds on a few very simple principles that, partly due to its simplicity, have allowed the Internet to grow to the global network of networks it is today. In its simplest form, DNS is a hierarchical, globally distributed database that allows everyone to map names to number, and vice versa. However, not that we do have a global database, can we use it to distribute other information? In this talk, I’ll introduce the basic principles underlying the DNS and some of the newer protocols, that leverage DNS to distribute information to make the Internet a safer place.
