Ensuring that inetd services like echo, time, rsh, and telnet are not enabled are all examples of what type of action?

Older, insecure services like chargen, daytime, echo, time, rsh, and telnet are all managed by inetd in Linux distributions. Disabling these services is a common item in security hardening benchmarks like the CIS benchmarks. These services are not Windows services, they are not SQL-related, and disabling them is not a type of patching.
