| Description | ||||
| Local initialization files are used to configure the user's shell environment upon logon. Malicious modification of these files could compromise accounts upon logon. World-readable "dot files" such as .bash_history or .netrc can reveal plaintext credentials, such files should be further protected (e.g., 0600). | ||||

Check Text (C-269276r1050158_chk)
Verify that all local initialization files have a mode of "0740" or less permissive with the following command:
Note: The example will be for the "testuser" account, who has a home directory of "/home/testuser".
$ find /home/testuser/.[^.]* -maxdepth 0 -perm -740 -exec stat -c "%a %n" {} \; | more
755 /home/testuser/.cache
755 /home/testuser/.mozilla
If any local initialization files have a mode more permissive than "0740", this is a finding.
