What is DNS in Cybersecurity?
The Domain Name System translates human-readable domain names (like example.com) into IP addresses that computers use to route traffic. DNS operates as a distributed hierarchical database with root servers, TLD servers, and authoritative nameservers resolving queries in milliseconds.
Why DNS Matters for Your Cybersecurity Career
DNS is one of the most abused protocols in cybersecurity. Attackers use DNS tunneling to exfiltrate data, DNS poisoning to redirect users, and domain generation algorithms to maintain botnet command channels. Security analysts monitor DNS logs as a primary detection source for malicious activity.
