Answer:
Domain Name System Security Extensions (DNSSEC)
Explanation:
The Internet Engineering Taskforce has specified the Domain name system Security Extensions or the DNSSEC for ensuring the security of various types of information being provided by the DNS as being implemented on the Internet protocol (IP) networks.
The DNSSEC saves the internet community from the fraudulent DNS data through the use of the public key cryptography that is being used to digitally sign the authoritative zone data as it enters the system and then does the required validation at the destination.
