Which aspect of security is DNSSEC designed to ensure?
Click on the arrows to vote for the correct answer
A. B. C. D.A.
DNSSEC is a security extension to the regular DNS protocol and services that allows for the validation of the integrity of DNS lookups.
It does not address confidentiality or availability at all.
It allows for a DNS client to perform DNS lookups and validate both their origin and authority via the cryptographic signature that accompanies the DNS response.
DNSSEC (Domain Name System Security Extensions) is a security protocol designed to ensure the integrity of the Domain Name System (DNS). DNS is a critical component of the Internet infrastructure, responsible for translating domain names into IP addresses, which are then used to locate web servers and other network resources.
DNSSEC was developed to address security weaknesses in the DNS that can be exploited by attackers to redirect users to fake websites or intercept their traffic. The protocol uses digital signatures to authenticate DNS responses and prevent unauthorized modifications to the DNS data.
In other words, DNSSEC ensures the integrity of the DNS by providing a way to verify that the DNS information has not been tampered with or modified in transit. This protects against attacks like DNS spoofing, where an attacker intercepts DNS requests and returns false information to redirect users to malicious websites.
Therefore, the correct answer to the question is A. Integrity. DNSSEC does not provide authentication, availability, or confidentiality of DNS data. Its main goal is to ensure the integrity and authenticity of DNS data.
