In this course you will learn how to secure an Ubuntu Linux server against attacks from hackers because these simple steps can block most basic hacking attempts and provide peace of mind when running our servers.
Why take the 45 minutes to quickly secure our servers as soon as we get them?
Amateur hackers can crack our default hosting provider settings fairly easily using programs downloaded from the Internet. We can block these hacks with just a few minutes of running the commands in the Command Line Interface I show here and signing in with RSA keys instead of passwords!
I hope that this course filmed using Ubuntu Linux 16.04 will be useful for you.
