Azure DNS now supports DNSSEC (Domain
Name System Security Extensions) in our azure public cloud, a significant
enhancement to our DNS services. This new feature provides an additional layer
of security to your domain names, ensuring the integrity and authenticity of
your DNS data. API, CLI and PowerShell is available today, with portal being
deployed over the next 2 weeks. For more information, please refer to our Azure DNSSEC documentation.
What is DNSSEC?
DNSSEC is a suite of extensions to DNS that adds security to
the domain name system. It helps protect against certain types of attacks, such
as cache poisoning and man-in-the-middle attacks, by enabling DNS responses to
be verified for authenticity. With DNSSEC, you can be confident that the DNS
responses you receive are exactly what the domain owner intended.
Key Benefits of DNSSEC on Azure DNS
- Enhanced
Security: DNSSEC helps prevent attackers from manipulating or
poisoning DNS responses, ensuring that users are directed to the correct
websites.
- Data
Integrity: By signing DNS data, DNSSEC ensures that the information
received from a DNS query has not been altered in transit.
- Trust
and Authenticity: DNSSEC provides a chain of trust from the root DNS
servers down to your domain, verifying the authenticity of DNS data.
