=== Part 1: How do we Manage System Services? ===
We have seen At the beginning of this lab we mentioned that maintaining running unneeded '''packages can be a security risk''' due to the unnecessary increase in the complexity of your system. Similarly, it is also unnecessarily hazardous, and even more so, to leave unneeded services running. In this investigation, we will learn how to '''control services, and turn off those services that we think are not necessary to help reduce security risks'''.
Although there is a command called: '''service''' that may appear to manager services on your Linux system, it is considered <u>'''deprecated'''</u> (i.e. "obsolete"). It has been replaced by using the [http://zenit.senecac.on.ca/wiki/index.php/Init_vs_systemd#systemd_Command_Usage systemctl] command.
