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.
This video steps through what benefits DNSSEC provides and one of the common attacks which can be conducted against DNS.

I’ve been following these videos for 3 days and this is the easiest I’ve learned in 10 years as a tech engineer and I work for Microsoft

@LearnCantrill Год назад

Thanks Bettina I really appreciate the feedback. Feel free to share these videos around - they’re my way of giving back so I want them in front of all the people ;)

I think youtube fixed their algorithm this summer, because now I'm starting to find jewel channels like this. Awesome stuff

@LearnCantrill Год назад

Please share it around on social media. It really helps.

I have watched several videos about DNSSEC but nothing gave crystal clear explanations as this one. I like the graphics used as well. Thank you very much for your effort! 💚

why does DNS resolver easily except the result from the person who is not pointed by the root sever? at 6:00

(I know it's late, but in case if anyone's wondering) The short answer is that DNS messages are sent through UDP, which is a stateless protocol and the source IP-address is blindly trusted. So if a bad guy has an access to a query traffic, he can spam fake UDP responses pretending to be the authoritative server. It's called DNS cache poisoning, though it is difficult to implement but it's possible.
