DNSSEC was designed to add a layer of security to the DNS protocol. Which type of attack was the DNSSEC extension designed to mitigate? 

Answer options:

A. Account hijacking
B. Snooping
C. Spoofing
D. Data exposure

C

DNSSEC is an extension to the regular DNS protocol that utilizes digital signing of DNS query results, which can be verified to come from an authoritative source. This verification mitigates the ability for a rogue DNS server to be used to spoof query results and to direct users to malicious sites. DNSSEC provides for the verification of the integrity of DNS queries. It does not provide any protection from snooping or data exposure. Although it may help lessen account hijacking by preventing users from being directed to rogue sites, it cannot by itself eliminate the possibility.
