Verify all local initialization files have a mode of "0740" or less permissive using 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---- 1 wadea users 896 Mar 10 2011 .profile
-rwxr---- 1 wadea users 497 Jan 6 2007 .login
-rwxr---- 1 wadea users 886 Jan 6 2007 .something
If any local initialization files have a mode more permissive than "0740", and is not documented with the information system security officer (ISSO) as an operational requirement, this is a finding.
