Ensure local interactive user home directories are configured

中レベル 1自動freebsd

説明

The user home directory is space defined for the particular user to set local environment variables and to store personal files. While the system administrator can establish secure permissions for users' home directories, the users can easily override these. Users can be defined in /etc/passwd without a home directory or with a home directory that does not actually exist. Audit: interactive users (uid >= 1000 with a login shell) must have an existing home they own that is mode 755 or stricter.
