No Telnet, Yes SSH

Most network equipment has telnet enabled by default. These days most devices can also support a protocol called SSH. I would suggest that you disable the insecure protocol telnet and enable a secure protocol called SSH. Why? Telnet allows passwords to be seen in clear text and if someone is smart, they are able to capture your password.

If you ever have a security audit, this will be one of the first items they are looking for.
