networking - Security of DNS answers -


i have been searching information regarding topic found no direct answer. possible following happen:

pc 1: -opens udp socket in port x -sends request dns server resolve name

meanwhile

a hacker captures packet in internet, , himself answers request wrong answer

can happen? if not, prevents this? dns uses ssl or security mechanism? our operative systems use secure communications dns servers?

thanks in advance

the scenario present possible. it's 1 of reasons why dnssec invented.

dnssec allows resolver client check chain of cryptographic signatures dns record way tree trust anchor (which dns root).
