Description
If the skeleton files are not protected, unauthorized personnel could change user startup parameters and possibly jeopardize user files.
ℹ️ Check
At the command line, run the following command:
# stat -c "%n permissions are %a and owned by %U:%G" /etc/skel/.[^.]*
Expected result:
/etc/skel/.bash_logout permissions are 750 and owned by root:root
/etc/skel/.bash_profile permissions are 644 and owned by root:root
/etc/skel/.bashrc permissions are 750 and owned by root:root
If the output does not match the expected result, this is a finding.
✔️ Fix
At the command line, run the following commands:
# chmod 750 /etc/skel/.bash_logout
# chmod 644 /etc/skel/.bash_profile
# chmod 750 /etc/skel/.bashrc
# chown root:root /etc/skel/.bash_logout
# chown root:root /etc/skel/.bash_profile
# chown root:root /etc/skel/.bashrc
