What does 'DNS Spoofing' involve?

DNS Spoofing, also known as DNS cache poisoning, is a type of cyber attack that takes advantage of vulnerabilities in the Domain Name System (DNS). In this attack, malicious actors insert corrupt DNS data into the cache of a resolver to redirect users from legitimate websites to fraudulent ones without their knowledge. This effectively means that when a user tries to visit a trusted website, they might be led to an imposter site that could be used to steal sensitive information or deploy malware.

The essence of DNS Spoofing lies in the manipulation of DNS queries and responses, which can create confusion or misdirection for users, making it a direct exploitation of the weaknesses in DNS protocols. By understanding this attack vector, security professionals can take preventive measures to fortify their DNS infrastructure and protect against such vulnerabilities.

Other options relate to different types of cybersecurity concepts; one addresses a method that alters database contents, another discusses bypassing firewalls, and the last option incorrectly suggests a technique for enhancing security. While those topics are relevant within the broader domain of cybersecurity, they do not accurately define DNS Spoofing itself, which is specifically tied to the exploitation of DNS weaknesses.
