Ensure remote login warning banner is configured properly

낮음레벨 1자동freebsd

설명

The contents of the /etc/issue.net file are displayed to users prior to login for remote connections from configured services. 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/issue.net must not disclose the OS version from /etc/os-release; review the wording against site policy.
