TDL 020 | Why DNS Is Your First Line of Cyber Defense | Chris Buijs

**Executive Summary:** This episode transcript and article argue that DNS is the first and last line of cyber defense, highlights common operational risks (set-it-and-forget-it mentality, siloed Networking/Security/DNS teams, inadequate automation and visibility), calls out abuse vectors such as DNS/NTP amplification and rapid discovery by scanners like Shodan/Censys, and recommends integrating hardened DNS practices (visibility, automation, TSIG, inclusion in DevSecOps/Zero Trust) into enterprise security architecture.
