Securing your Ubuntu Desktop

We all know that using Linux in terms of security is secure enough. But, if we could secure it further, then that would be great!

Here are 4 things that I do to further secure my Ubuntu 18.04 desktop.

This time we need to open the Terminal app.
To open the Terminal app, click Show All Applications and locate Terminal.
On your desktop, Press Ctrl+Alt+T

1. Disable the su user.
command: sudo passwd -l root

2. Enable the ufw firewall.
commandsudo ufw enable

3. Prevent IP Spoofing
commandsudo /etc/host.conf
include: nospoof on
to save:
Press: Ctrl + x
Press: Enter

4. Secure Shared Memory
commandsudo /etc/fstab
include: tmpfs /dev/shm tmpfs defaults,noexec,nosuid 0 0
to save:
PressCtrl + x

Reboot your system.

That's it! Anything that I missed?

Hmmm... Maybe you are still hesitating to install Ubuntu 18.04 desktop to your loved Windows computer, well... you can do a virtualization of Ubuntu within your Windows machine. 
For the record, I love MS Windows. My laptop is pre-installed with a licensed copy of Windows 10. What I am trying to say is that if your copy of Windows is pirated, better change it to Linux instead!
Virtualization is creating a virtual computer within your Windows system. The good thing about virtualization is that you can simultaneously work with your Windows and your virtual machine.
Your virtual machine can access your Windows drives thus sharing files will be a breeze.
With virtualization, we will be using Oracle's VirtualBox. This is free and supports multiple guest operating systems. A link to the VirtualBox will be shared at the end of this article.
You must remember that VirtualBox version 6.0 and above only supports 64bit systems. Which means the latest VirtualBox that you can get for 32bit systems …

Creating "bootable" disks

Greetings everyone! Today, ill share with you how I create a bootable Ubuntu 18.04 desktop disk to be used when trying or installing Ubuntu onto your rig.

This guide will work with Windows systems as well.

All of the software that I will be using will be posted below.

The tool that I am using when creating bootable disks is an application called Rufus. This app is a portable app which means that the app will run without any installation.

Rufus is a Windows only application thus you need a Windows computer to run this awesome app.

1. Before opening rufus, you need to insert your USB stick to computer. This is the interface of rufus. On the Device, your USB drive name will appear indicating that rufus has successfully recognized your device.

There will be an error message that pops out incase rufus was unable to detect your inserted USB.


2. Locate the location of your Ubuntu 18.04 iso. Click Open.

3. The Boot selection will be changed to the file name of your Ubuntu iso.

Ubuntu 18.04 default applications

OK. You might be asking what are the default applications on a new Ubuntu 18.04 installation. Well, there are several basic applications that comes with a new installation to get you up and running. These are the following:

1. On the left side corner of your screen is your favorites bar. The following applications are the default applications that were inserted.

2. By clicking on the Show all Applications, you will be shown all the applications that were installed together with Ubuntu 18.04 on your computer.  There is also Remmina (a remote desktop client) installed! (NOTE: RDP for Windows 10 is only available to PRO editions)

3. Scrolling down your mouse shows the next list of applications installed.
(NOTE: Your Videos app can also  play your audio files)

4. You can modify your favorites bar applications

5. As well a removing the apps that you do NOT usually use. When removing, only the icon (shortcut) will be removed. It will not uninstall your removed applications

There you go. Th…
