How to Install VirtualBox Guest Additions in Security Onion 14.05

After having to piece together a VirtualBox Guest Addition installation method from some old articles, I decided to put together one for Security Onion 14.05.

Once you have Security Onion 14.05 installed and running, start the Terminal Emulator and walk through the following commands, one-by-one:

sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade
sudo shutdown -r now

After the reboots, launch the Terminal Emulator and run the following commands:

sudo apt-get install build-essential module-assistant dkms
sudo add-apt-repository universe
sudo apt update
sudo m-a prepare

In the virtual machine window, select Devices > Insert Guest Additions CD image

cd /media/%username%/VBOXADDITIONS (tab complete)
sudo ./
sudo shutdown -r now

After the reboot, the VirtualBox Guest Additions should be installed and all features should be available.

As a last step, select Devices > Optical Drives > Remove disk from virtual drive…
