Cyber Security | DNSSEC explained | DNSSEC Purpose | How DNSSEC Works Step by Step | Infosec

The Domain Name System Security Extensions (DNSSEC) is a suite of Internet Engineering Task Force (IETF) specifications for securing certain kinds of information provided by the Domain Name System (DNS) as used on Internet Protocol (IP) networks. It is a set of extensions to DNS which provide to DNS clients (resolvers) origin authentication of DNS data, authenticated denial of existence, and data integrity, but not availability or confidentiality.
The original design of the Domain Name System (DNS) did not include security; instead, it was designed to be a scalable distributed system. The Domain Name System Security Extensions (DNSSEC) attempts to add security, while maintaining backward compatibility. RFC 3833 documents some of the known threats to the DNS and how DNSSEC responds to those threats.

I think that was the most relaxing cyber security video I've ever watched :)

[MrSaeeshnaik]

this video deserves more likes and subs.... very well explained

[robbinhood]

I think no other animation video are available in internet as much as simple like this to explain DNS security

[dillon]

We need to see more of these types of videos. Wow!

Let's just hope the hackers only know how to make a "Cloned DNS" and not a "Cloned Example Bank". If only we had some sort of encryption protocol and some sort of public key infrastructure that could be used to verify the public key of the actual server you're talking to. If we had those things, there'd be no need for DNSSEC. I reckon if we had that, "TLS" would be a pretty cool name for it.

why are they hosting example bank on their local network? .. how what appears "the internet" give a non routable IP address?.

Really great visual. I was hoping that this would explain the signing of root servers on to TLD servers etc. though :D

awesome explanation and I like the graphics!!
