Demonstration of DNSSEC protocol using IMUNES system

Ukratko su objašnjeni najvažniji pojmovi vezani za DNS, sigurnosni problemi koji se javljaju i sigurnosno proširenje DNSSEC te način rada DNSSEC-a i zašto je bitan. Nakon toga prikazan je jedan način konfiguracije potrebnih datoteka. Uspostava DNSSEC-a nije nimalo jednostavna i lako se mogu dogoditi pogreške, a svaka i najmanja pogreška prouzročit će neispravan rad sustava. Iz tog razloga DNSSEC još uvijek nije implementiran na velikom broju DNS poslužitelja i zato je u ovom radu prikazano korak po korak kako implementirati DNSSEC, a nakon toga i kako provjeriti funkcionira li sustav ispravno, odnosno potpisuju li se zone i validiraju li se DNS odgovori.The most important terms regarding DNS are explained, the security problems that arise, the security extension DNSSEC, the principles of how it works and why it is important. Afterwards, one way to configure the necessary files is shown. Setting up DNSSEC is not simple and mistakes can easily happen and even minor mistakes can cause the system to work incorrectly. For that reason DNSSEC is still not implemented on a large number of DNS servers and that is why this paper shows step-by-step instructions how to implement DNSSEC and how to verify if the system is working properly, meaning whether the zones are being signed and the DNS responses are being validated
