Ubuntu OS must disable kernel core dumps.

Description
Kernel core dumps may contain the full contents of system memory at the time of the crash. Kernel core dumps may consume a considerable amount of disk space and may result in denial of service by exhausting the available space on the target file system partition.

Who does this work

13 NICE work roles and 8 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.

Check Text (C-275568r1148289_chk)

Verify kernel core dumps are disabled with the following command: $ systemctl is-active kdump.service inactive If the "kdump" service is active, ask the system administrator (SA) if the use of the service is required and documented with the information system security officer (ISSO). If the service is active, this is a finding.

Fix Text (F-79575r1147753_fix)

Disable the "kdump" service with the following command: $ sudo systemctl disable kdump.service If kernel core dumps are required, document the need with the ISSO.
