DNS encryption
(also encrypted DNS traffic)
DNS encryption definition
DNS encryption refers to the process of encrypting DNS (Domain Name System) traffic, which helps enhance the security and privacy of internet communication. Also, encrypting DNS traffic can improve privacy and security of users. DNS encryption can protect from many types of DNS attacks. To encrypt DNS, using encryption protocols and configuring them on the network is necessary.

Methods of DNS encryption
DNS over TLS. DNS over TLS (DoT) is a DNS encryption method that uses the Transport Layer Security protocol to encrypt traffic. It provides end-to-end encryption and is easier to troubleshoot compared to other DNS encryption methods.
DNS over HTTPS. DNS over HTTPS (DoH) is another DNS encryption method that can be used for online protection. With this method, DNS data is sent through an HTTPS connection. And if someone intercepts the data, they’ll only be able to see the encrypted version, not the plaintext. Also, it uses end-to-end-encryption.
DNSCrypt. DNSCrypt is a protocol that can be used to encrypt DNS traffic. It uses end-to-end encryption to encrypt traffic and has the ability to prevent spoofing attacks.
