Verify that all local initialization files have a mode of "0740" or less permissive. Check the mode on all local initialization files with the following command: Note: The example will be for the "smithj" user, who has a home directory of "/home/smithj". # ls -al /home/smithj/.[^.]* \| more -rw-------. 1 smithj users 2984 Apr 27 19:02 .bash_history -rw-r--r--. 1 smithj users 18 Aug 21 2019 .bash_logout -rw-r--r--. 1 smithj users 193 Aug 21 2019 .bash_profile If any local initialization files have a mode more permissive than "0740", this is a finding.
