DNS Architecture Patterns
RCCE students will learn Domain Name System security including DNS architecture, DNSSEC, DNS over HTTPS/TLS, DNS tunneling detection, DNS sinkholing, and DNS-based threat detection. RCCE students will learn to configure DNS infrastructure securely, implement DNSSEC for zone integrity, detect and block DNS-based attacks including cache poisoning, DNS tunneling, domain generation algorithms, and DNS rebinding, configure DNS-based security controls for threat blocking, analyze DNS logs for indicators of compromise, deploy DNS monitoring for threat detection, and respond to incidents involving DNS infrastructure compromise or abuse. This architecture course teaches secure system design using proven patterns, guardrails, and reference architectures. Building on core knowledge, RCCE students will learn to evaluate design options against security requirements, make informed trade-off decisions, and build systems that are resilient by design. Students gain the architectural thinking skills needed for security engineering and solution design roles.
