prevent dns cache poisoning

DNSSEC helps prevent DNS attacks like DNS cache poisoning and DNS spoofing.
DNSSEC does not protect the entire server, it only protects the data exchanged between signed zones.

How is DNS spoofing prevented?

To protect from DNS spoofing, internet providers can use DNSSEC (DNS security).
When a domain owner sets up DNS entries, DNSSEC adds a cryptographic signature to the entries required by resolvers before they accept DNS lookups as authentic.

What are the defense options against cache poisoning?

As for cache poisoning, a very DNS-specific attack, the most common fix is to update the DNS software so that queries are sent from more random source ports.
This effectively lessens the chance that an attacker will successfully guess all five (5) fields in the answer.

How can we protect against DNS cache poisoning?

However, the long-term answer (according to the experts) is by using Domain Name System Security Extensions (DNSSEC).
This is a technology designed to combat DNS poisoning, and in simple terms, it puts different levels of verification in place.
Going deeper, DNSSEC uses “public-key cryptography” as verification._{12 déc. 2023}
