Telnet is inherently insecure because it doesn't encrypt communication
going across the wire, particularly passwords. That's why the world is
migrating to SSH.

Using TCP Wrappers you can tighten the security on telnet, allowing only
certain IP addresses or domains access, etc, but the communication will
still be unencrypted.

You can start by taking a look at /etc/hosts.allow and /etc/hosts.deny.
