Ensure message of the day is configured properly

낮음레벨 1자동freebsd

설명

The contents of the /etc/motd file are displayed to users after login and function as a message of the day for authenticated users. Unix-based systems have typically displayed information about the OS release and patch level upon logging in to the system. This information can be useful to developers who are developing software for a particular OS platform. Audit: /etc/motd must not disclose the OS version from /etc/os-release; review the wording against site policy.
