RHEL 10 must enforce that all local initialization files configured by systemd-tmpfiles have mode "0600" or less permissive.

Excessive permissions on local interactive user home directories may allow unauthorized access to user files by other users.

Verify RHEL 10 enforces that all local initialization files configured by systemd-tmpfiles have mode "0600" or less permissive.

Check that all files from "/usr/share/rootfiles/" are overridden correctly in RHEL 10:

$ sudo grep /usr/share/rootfiles/ /etc/tmpfiles.d/*.conf C /root/.bash_logout 600 root root - /usr/share/rootfiles/.bash_logout C /root/.bash_profile 600 root root - /usr/share/rootfiles/.bash_profile C /root/.bashrc 600 root root - /usr/share/rootfiles/.bashrc C /root/.cshrc 600 root root - /usr/share/rootfiles/.cshrc C /root/.tcshrc 600 root root - /usr/share/rootfiles/.tcshrc

If any files are not configured to "600", or if no files are found by grep, this is a finding.

Configure RHEL 10 to enforce that all local initialization files configured by systemd-tmpfiles have mode "0600" or less permissive.

Ensure the following lines are in a ".conf" file under "/etc/tmpfiles.d/":

C /root/.bash_logout 600 root root - /usr/share/rootfiles/.bash_logout C /root/.bash_profile 600 root root - /usr/share/rootfiles/.bash_profile C /root/.bashrc 600 root root - /usr/share/rootfiles/.bashrc C /root/.cshrc 600 root root - /usr/share/rootfiles/.cshrc C /root/.tcshrc 600 root root - /usr/share/rootfiles/.tcshrc
