cfbs add telnet-server-not-installed
Telnet is a protocol for providing an insecure remote virtual terminal access to hosts over network. It is generally considered obsolete and dangerous and its use has been a root cause of security issues. It should not be used except for very specific use cases.
This module makes sure that the Telnet server packages are not installed on hosts and thus also not running.
Example of a cf-agent run on a host that has the telnet-server package installed:
[root@hub]# cf-agent -KI
info: Successfully removed package 'telnet-server'
If Telnet server packages are really needed on some specific hosts, they can be
marked as such by defining the hardening_telnet_server_allowed class in either
augments or CMDB.
