What is one advantage of DNSSEC for DNS integrity?

One of the key advantages of DNSSEC (Domain Name System Security Extensions) is its ability to protect against cache poisoning attacks. Cache poisoning occurs when an attacker successfully inserts false data into the DNS cache of a resolver. This can lead to users being directed to malicious sites instead of their intended destinations. DNSSEC addresses this vulnerability by adding a layer of security to the DNS lookup process through the use of digital signatures. When a DNS resolver receives a response to a DNS query, it can verify the authenticity of the response by checking the digital signatures provided in the DNSSEC records. If the signatures are valid, the resolver can trust that the response is legitimate and has not been tampered with. This ensures that the integrity of DNS data is maintained, effectively mitigating the risks associated with cache poisoning. Other options, while related to DNS, do not directly correlate with DNS integrity in the context of preventing unauthorized modification of DNS data.
