You're seeing pseudo ttys created by network connections such as ssh,
telnet, etc. These aren't the same as the physical ttys, /dev/tty* which
relate directly to hardware devices including the console.
Services such as ssh are generally secured using their own configuration
files and/or tcp_wrappers via the /etc/hosts.allow file (and
/etc/hosts.deny if you like, but I find it much easier to have everything
in one file).
