What is DNSSEC?

DNSSEC, which stands for Domain Name System Security Extensions, is a vital security protocol designed to enhance the integrity and authenticity of data within the Domain Name System (DNS). This protocol addresses a significant vulnerability in the DNS architecture that can be exploited through various attacks, such as cache poisoning and man-in-the-middle scenarios. By utilizing cryptographic signatures, DNSSEC ensures that DNS responses are not tampered with, allowing users to verify that the information received accurately reflects the intended domain.

When a user tries to access a website, DNSSEC helps prevent malicious actors from redirecting them to fraudulent or harmful sites. It works by establishing a chain of trust through public key cryptography, enabling users’ systems to confirm the legitimacy and reliability of DNS records. Overall, DNSSEC plays a crucial role in securing internet communications and enhancing user confidence by ensuring that they reach the correct destinations online.
