It's 2 years since #NIST released the Cybersecurity Framework 2.0. One of its most useful effects is making critical services an explicit governance and risk topic, not just an IT detail. When #DNS, #DHCP and #IPAM are treated as those critical services, the #CSF functions map cleanly to operational decisions on ownership, hardening, monitoring, resilience targets and recovery readiness, because outages or abuse at this layer can take whole environments down.
