Fix Recommendation

Configure OL 9 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

Check Contents

Verify that OL 9 "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" "/etc/bashrc" file, the severity of this requirement is raised to a CAT I.

$ grep umask /etc/bashrc
umask 077
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.
