DNS stands for Domain Name System. DNS translates human-readable domain names into IP addresses. It acts as the internet's phone book and is critical infrastructure for all networked services.
How DNS Is Used in Cybersecurity
Cybersecurity teams monitor DNS queries for signs of data exfiltration, domain generation algorithms, and command-and-control traffic. Threat intelligence analysts track malicious domains through passive DNS data. Security engineers deploy DNS filtering and DNSSEC to block threats at the network layer.
