In today’s world, if you’re not constantly working to secure your servers, you’re already 10 steps behind every hacker on the planet. And if you happen to be a Linux systems administrator, you might think it doesn’t apply to you. It does.

Even though the Linux open source platform is considerably more secure than many other operating systems, there are still things you must do to harden those deployments. If you ignore these tasks, it’s not a matter of if but when your machines will be compromised.

So what do you do? In this TechRepublic Premium article, written by Jack Wallen, we’ll share a handy list of nine things you should consider for all of your Ubuntu Server deployments.

Never use root

Fortunately, Ubuntu ships with a root account that isn’t accessible, because no password has been set. That doesn’t of course, mean you can’t enable it, or even access the root account with the command sudo -s. Unless it is absolutely necessary, don’t do this. In fact, you should consider disabling the root account altogether. So long as you have a regular user that belongs to the sudo group, you’ll still be able to take care of everything you need on the server.
