What is DNSSEC and how it works?

DNSSEC strengthens authentication in DNS using digital signatures based on public key cryptography. With DNSSEC , it’s not DNS queries and responses themselves that are cryptographically signed, but rather DNS data itself is signed by the owner of the data. Every DNS zone has a public/private key pair.

What does DNSSEC stand for?

Domain Name System Security Extension
DNSSEC stands for Domain Name System Security Extension. It is a mechanism that uses cryptography to provide authentication and integrity for DNS queries.

What is DNS RFC?

The Domain Name System (DNS) is a hierarchical decentralized naming system for computers, services, or any resource connected to the Internet or a private network. It associates various information with domain names assigned to each of the participating entities.

Should I enable DNSSEC for my domain?

It secures DNS lookups by signing your DNS records using public keys. With DNSSEC enabled, if the user gets back a malicious response, their browser can detect that. The attackers do not have the private key used to sign the legitimate records, and can no longer pass off a forgery.

Are there any RFCs that refer to DNS security extensions?

Show complete RFC 4034 (Mar 2005) Show all RFCs that refer to RFC 4034. This document is part of a family of documents that describe the DNS Security Extensions (DNSSEC). The DNS Security Extensions are a collection of resource records and protocol modifications that provide source authentication for the DNS.

Which is the core of the DNSSEC protocol?

Note: Core DNSSEC RFCs are RFC 4033, RFC 4034, and RFC 4035 (old DNSSEC RFC 2535 is now obsolete). This document specifies how DNSSEC cryptographic algorithm identifiers in the IANA registries are allocated.

When was DNS Security introduced in RFC 4033?

RFC 4033 DNS Security Introduction and Requirements March 2005 The DNS security extensions provide origin authentication and integrity protection for DNS data, as well as a means of public key distribution. These extensions do not provide confidentiality.

How does DNSSEC help protect against spoofing attacks?

With DNSSEC, the DNS protocol is much less susceptible to certain types of attacks, particularly DNS spoofing attacks. The core DNSSEC extensions are specified in the following Request for Comments (RFCs). Additional RFCs provide supporting information.
