Episode 48 — DNS Security — DNSSEC, DoH, DoT
In this episode, we explore how securing the Domain Name System (DNS) protects against spoofing, cache poisoning, and man-in-the-middle attacks. We explain DNSSEC’s role in verifying authenticity through digital signatures, DNS over HTTPS (DoH) for encrypting queries in HTTPS traffic, and DNS over TLS (DoT) for protecting queries at the transport layer. Each method’s operational trade-offs and deployment considerations are addressed.
We also connect DNS security to broader cloud architecture strategies, showing how it integrates with firewalls, content filtering, and access control systems. This knowledge is tested in the Cloud+ exam’s security domain, where you’ll need to identify appropriate DNS protections for different threat models. Produced by BareMetalCyber.com, offering more prepcasts, books, and secure DNS deployment guides.
