NCA Critical Systems controls add stronger cybersecurity expectations for systems classified as critical.
Official source
What teams need to do
- Identify systems classified as critical and document the rationale.
- Map applications, infrastructure, data, privileged access, providers, remote support, and recovery
dependencies.
- Apply stronger controls for access, hardening, monitoring, change, vulnerability, backup, and
incident response.
- Review supplier and remote access carefully.
Evidence to maintain
- Critical system inventory and classification records.
- Control mapping and operating evidence.
- Supplier, remote access, incident, backup, and recovery evidence.
- Exceptions, remediation, and reporting.
Common gaps
- Criticality is assigned without dependency mapping.
- Supplier remote access is not reviewed tightly enough.
- Backup and recovery evidence is not tied to critical system requirements.

Halbarad helps connect critical systems to providers, fourth parties, controls, access evidence, incidents, recovery, and remediation.
