Does HTTPS use DNSSEC?
[00:55:22] – DNS over HTTPS is DNS, but encrypted over the HTTPS protocol. DNSSEC is a protocol extension to a DNS server that allows you to establish a chain of trust, so that the endpoint receiving a response from a DNS server can be confident that the response can be trusted.
Why it is important to use DNSSEC to prevent DNS spoofing attacks?
DNSSEC protects the user from getting bad data from a signed zone by detecting the attack and preventing the user from receiving the tampered data.
Does HTTPS prevent DNS poisoning?
Consider Forcing HTTPS With HSTS, you can force browsers to always load your website on HTTPS. This helps you avoid DNS cache poisoning in one key way: a hacker who creates a fake version of your website is unlikely to be able to get a trusted SSL/TLS certificate for your domain.
When does DNS server indicate that it understands DNSSEC?
When the DNS client issues a query, it can indicate to the DNS server that it understands DNSSEC. However, the client is non-validating. When issuing queries, the DNS client relies on the local DNS server to indicate that validation was successful.
Why are DNS servers vulnerable to an attack?
In environments that do not employ security technologies such as IPsec or HTTPS, the DNS protocol can be vulnerable to attack due to an inherent lack of authentication and integrity checking of data that is exchanged between DNS servers or is sent to DNS clients.
Do you need DNS server to do DNSSEC validation?
Additionally, if the DNS client is DNSSEC-aware, it can be configured to require that the DNS server perform DNSSEC validation. The following figure shows the validation process.
When to use DNSSEC recursive or forwarding DNS server?
When a DNSSEC-aware recursive or forwarding DNS server receives a query from a DNS client for a DNSSEC-signed zone, it will request that the authoritative DNS server also send DNSSEC records, and then attempt to validate the DNS response using these records.
