RHEL 10 must define default permissions for the bash shell.

Overview

Finding ID	Version	Rule ID	IA Controls	Severity

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.

Check Text (C-281080r1184687_chk)

Verify RHEL 10 "umask" setting is configured correctly in the "/etc/bashrc" file with the following command: Note: If the value of the "umask" parameter is set to "000" in the "/etc/bashrc" file, the Severity is raised to a CAT I. $ sudo grep umask /etc/bashrc [ `umask` -eq 0 ] && 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-85546r1165594_fix)

Configure RHEL 10 to define default permissions for all authenticated users using the bash shell. Add or edit the lines for the "umask" parameter in the "/etc/bashrc" file to "077": umask 077
