Explanation

DNS tunneling is a technique used to bypass network security controls by encapsulating non- DNS traffic within DNS packets. By embedding malicious data into the DNS protocol packets, an attacker can bypass firewalls and other security controls that are not configured to inspect DNS traffic. DNSSEC zone walking is a technique used to extract information from DNSSEC-signed zones by iterating over the DNS tree. DNS cache snooping is a technique used to obtain information about a DNS server's cache by sending queries for non-existent domain names. DNS enumeration is a technique used to gather information about a target network by querying DNS servers for information about the network's hosts and services.
