Dns Security — CompTIA Network+ (N10-009) Practice Questions
DNS security encompasses the controls and protocols used to protect the Domain Name System from manipulation, spoofing, and abuse. Key technologies tested on the Network+ exam include DNSSEC, which adds cryptographic signatures to DNS records to verify authenticity, and DNS filtering, which blocks queries to known malicious domains. Candidates should also understand DNS cache poisoning attacks and how features like DNS over HTTPS (DoH) and DNS over TLS (DoT) protect query privacy.
