DNSSEC, short for Domain Name System Security Extensions, is a set of protocols that aim to secure the domain name system (DNS) against various security threats such as spoofing, cache poisoning, and eavesdropping. DNSSEC is designed to protect the authenticity and integrity of the information in the DNS, ensuring that users receive the correct information from authoritative sources.
How Does DNSSEC Work?
DNSSEC works by adding cryptographic signatures to DNS data. The signatures are created by a trusted third party, known as a key signing key (KSK), and are stored in the DNS record along with the original data. When a user sends a DNS query, the DNSSEC-enabled server will use the signatures to verify the authenticity of the data and ensure that it has not been altered in transit. If the data is not valid, the server will reject the request and the user will receive an error message.
