Ensure telnet server is not enabled
The telnet-server package contains the telnet daemon, which accepts connections from users from other systems via the telnet protocol.
Parameter:
[no/yes]
Technical Mechanism:
The telnet protocol is insecure and unencrypted. The use of an unencrypted transmission medium could allow a user with access to sniff network traffic the ability to steal credentials. The ssh package provides an encrypted session and stronger security.
Fix:
Remove or comment out any telnet lines in /etc/inetd.conf:
#telnet stream tcp nowait telnetd /usr/sbin/tcpd /usr/sbin/in.telnetd
