NIST Elevated DNS Security. Censys Active DNS Connects Names to Live Internet Infrastructure.

Censys announces Active DNS, a service that actively resolves domain names against authoritative infrastructure and links DNS records to hosts, services, certificates, and threat context to help security teams align DNS visibility with NIST CSF 2.0 functions (Identify, Detect, Respond, Recover). The document emphasizes active resolution and historical DNS data as investigative infrastructure to support exposure management, threat hunting, incident response, and SOC workflows.
