Discussion

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

Check Content

Verify that all SUSE operating system local initialization files have a mode of "0740" or less permissive.

Check the mode on all SUSE operating system local initialization files with the following command:

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

# ls -al /home/dosuser/.* | more
-rwxr-xr-x  1 dosuser users   896 Mar 10  2011 .profile
-rwxr-xr-x  1 dosuser users   497 Jan  6  2007 .login
-rwxr-xr-x  1 dosuser users   886 Jan  6  2007 .something

If any local initialization files have a mode more permissive than "0740", this is a finding.

Fix Text

Set the mode of SUSE operating system local initialization files to "0740" with the following command:

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

# chmod 0740 /home/dosuser/.<INIT_FILE>
