The Nokia router must be configured to have all inactive interfaces disabled.

Description
An inactive interface is rarely monitored or controlled and may expose a network to an undetected attack on that interface. Unauthorized personnel with access to the communication facility could gain access to a router by connecting to a configured interface that is not in use. If an interface is no longer used, the configuration must be deleted and the interface disabled. For subinterfaces, delete subinterfaces that are on inactive interfaces and delete subinterfaces that are themselves inactive. If the subinterface is no longer necessary for authorized communications, it must be deleted.

Who does this work

18 NICE work roles and 10 EC-Council certifications.

This is an inference across published mappings, not a single claim by anyone. This check maps to a control, which maps to a Cybersecurity Framework outcome, which NIST assigns to the work roles below. EC-Council separately maps its certifications to those same roles.

A certification prepares someone for a role. It is not evidence that a holder is qualified, and neither NIST nor EC-Council has stated that any certification here addresses this check.

Work-role assignments published by NIST (NICE Framework Components 2.2.0 and the CSF 2.0 OLIR crosswalk). Certification mappings published by EC-Council.

Fix Text (F-88373r1203957_fix)

Delete inactive subinterfaces and disable and delete the configuration of any inactive ports on the router. Disable inactive ports using the configuration below: - configure port 1/1/c2/1 shutdown Disable inactive logical interfaces using the configuration below: - configure router interface "TO-PE2" shutdown
