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.
DNSSEC (Domain Name System Security Extensions) is a protocol extension designed to add an additional layer of security to the DNS (Domain Name System). The DNS is a crucial component of the internet infrastructure that translates human-readable domain names (e.g., www.example.com) into IP addresses (e.g., 192.0.2.1) that computers can understand.
One of the primary security concerns with the DNS is the potential for attackers to intercept or modify DNS traffic, which can result in a variety of attacks, such as account hijacking, snooping, spoofing, and data exposure.
DNSSEC was specifically designed to address the problem of DNS spoofing, also known as DNS cache poisoning. This is a type of attack in which an attacker inserts forged DNS data into the cache of a recursive DNS resolver. When users subsequently attempt to access the domain in question, they are directed to a malicious website or a fake login page, where their credentials can be stolen.
DNSSEC adds digital signatures to DNS records, enabling clients to verify that the DNS data they receive is authentic and has not been tampered with en route. This helps to prevent DNS spoofing attacks, as it becomes much more difficult for attackers to forge DNS records without being detected.
In summary, DNSSEC was designed to mitigate the threat of DNS spoofing, which is a type of attack that can lead to account hijacking, snooping, and data exposure. By adding digital signatures to DNS records, DNSSEC provides an additional layer of security to the DNS protocol, making it more difficult for attackers to intercept or modify DNS traffic.
