Description
A core dump includes a memory image taken at the time the operating system terminates an application. The memory image could contain sensitive data and is generally useful only for developers trying to debug problems.

Who does this work

5 NICE work roles and 5 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-281311r1167083_chk)

Verify RHEL 10 disables storing core dumps. Check the status of the "kernel.core_pattern" kernel parameter with the following command: $ sudo sysctl kernel.core_pattern kernel.core_pattern = |/bin/false If "kernel.core_pattern" is not set to "|/bin/false", or a line is not returned and the need for core dumps is not documented with the information system security officer as an operational requirement, this is a finding.

Fix Text (F-85777r1167082_fix)

Configure RHEL 10 to disable storing core dumps. Create a drop-in if it does not already exist: $ sudo vi /etc/sysctl.d/99-kernel_core_pattern.conf Add the following to the file: kernel.core_pattern = |/bin/false Reload settings from all system configuration files with the following command: $ sudo sysctl --system
