Secure DNS options appear in CloudNetX scenarios as targeted protections rather than blanket solutions, and this episode clarifies what each mechanism actually provides. It defines DNSSEC as a method for validating the authenticity and integrity of DNS responses, ensuring that records have not been tampered with in transit. It then explains DoT and DoH as transport-layer protections that encrypt DNS queries and responses to prevent on-path observation or manipulation. The first paragraph emphasizes that these technologies solve different problems, and that understanding the threat model—tampering versus eavesdropping versus policy enforcement—is essential for choosing the correct approach in a given scenario.
