Description
The changing of file permissions could indicate that a user is attempting to gain access to information that would otherwise be disallowed. Auditing discretionary access control (DAC) modifications can facilitate the identification of patterns of abuse among both authorized and unauthorized users.

Who does this work

6 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-281152r1166408_chk)

Verify RHEL 10 generates an audit record for all uses of the "umount" system call with the following command: $ sudo auditctl -l | grep b32 | grep 'umount\b' -a always,exit -F arch=b32 -S umount -F auid>=1000 -F auid!=-1 -F key=privileged-umount If the command does not return a line, or the line is commented out, this is a finding.

Fix Text (F-85618r1166407_fix)

Configure RHEL 10 to generate audit records upon successful and unsuccessful uses of the "umount" system call by adding or updating the following rules in "/etc/audit/audit.rules" and adding the following rules to "/etc/audit/rules.d/perm_mod.rules" or updating the existing rules in files in the "/etc/audit/rules.d/" directory: -a always,exit -F arch=b32 -S umount -F auid>=1000 -F auid!=unset -k privileged-umount Restart the audit daemon with the following command for the changes to take effect: $ sudo service auditd restart
