All TOSS 5 local initialization files must have mode 0740 or less permissive.

Local initialization files are used to configure the user's shell environment upon logon. Maliciously modifying these files could compromise accounts upon logon.

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.

Set the mode of the local initialization files to "0740" using the following command:

Note: The example will be for the wadea user, who has a home directory of "/home/wadea".

$ sudo chmod 0740 /home/wadea/.<INIT_FILE>
