1.6.5 Ensure 'Telnet' is disabled

Information

Disables the telnet access to the security appliance in the case it has been configured

Rationale:

Telnet is an unsecure protocol as username and password are conveyed in clear text during the administrator authentication and can be retrieved through network sniffing.

Solution

Run the following to remove the telnet access

hostname(config)#no telnet 0.0.0.0 0.0.0.0 <interface_name>
