RHEL 10 must prevent code from being executed on file systems that contain user home directories.

Description
The "noexec" mount option causes the system to not execute binary files. This option must be used for mounting any file system not containing approved binary files, as they may be incompatible. Executing files from untrusted file systems increases the opportunity for nonprivileged users to attain unauthorized administrative access.

Who does this work

17 NICE work roles and 9 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-281090r1165625_chk)

Verify RHEL 10 is configured so that "/home" is mounted with the "noexec" option with the following command: Note: If a separate file system has not been created for the user home directories (user home directories are mounted under "/"), this is automatically a finding, as the "noexec" option cannot be used on the "/" system. $ mount | grep /home /dev/mapper/luks-ca2261ed-7b00-4b7b-84cd-8cd6d8fa4b28 on /home type xfs (rw,nodev,nosuid,noexec,seclabel) If the "/home" file system is mounted without the "noexec" option, this is a finding.

Fix Text (F-85556r1165624_fix)

Configure RHEL 10 to prevent code from being executed on file systems that contain user home directories. Modify "/etc/fstab" to use the "noexec" option on the "/home" directory.
