Description |

The telnet service must be disabled, as it sends all data, including the user's password in a clear text form that can be easily intercepted and read. Passwords need to be protected at all times and encryption is the standard method for protecting passwords. If passwords are not encrypted, they can be plainly read (i.e., clear text) and easily compromised. Disabling telnet is one way to mitigate this risk. |
