Verify that OL 9 configures all local initialization files to have a mode of "0740" or less permissive with the following command: Note: The example will be for the "wadea" user, who has a home directory of "/home/wadea". $ sudo ls -al /home/wadea/.[^.]* | more -rwxr-xr-x 1 wadea users 896 Mar 10 2011 .profile -rwxr-xr-x 1 wadea users 497 Jan 6 2007 .login -rwxr-xr-x 1 wadea users 886 Jan 6 2007 .something If any local initialization files have a mode more permissive than "0740", this is a finding.
