RHEL 10 must define default permissions for the system default profile.

Description
The "umask" controls the default access mode assigned to newly created files. A "umask" of "077" limits new files to mode "600" or less permissive. "Although umask" can be represented as a four-digit number, the first digit representing special access modes is typically ignored or required to be "0". This requirement applies to the globally configured system defaults and the local interactive user defaults for each account on the system.

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-281083r1184689_chk)

Verify the RHEL 10 "umask" setting is configured correctly in the "/etc/profile" file with the following command: Note: If the value of the "umask" parameter is set to "000" in the "/etc/profile" file, the Severity is raised to a CAT I. $ sudo grep umask /etc/profile umask 077 If the value for the "umask" parameter is not "077", or the "umask" parameter is missing or is commented out, this is a finding.

Fix Text (F-85549r1165603_fix)

Configure RHEL 10 to define default permissions for all authenticated users in such a way that the user can read and modify only their own files. Add or edit the lines for the "umask" parameter in the "/etc/profile" file to "077": umask 077
