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 -rwxr----- 1 smithj users 896 Mar 10 2011 .profile -rwxr----- 1 smithj users 497 Jan 6 2007 .login -rwxr----- 1 smithj users 886 Jan 6 2007 .something If any local initialization files have a mode more permissive than "0740", this is a finding.
