Virtualization can be a pivotal resource when studying cybersecurityCybersecurity refers to the practice of protecting computers, servers, mobile devices, electronic systems, networks, and data from digital attacks, damage, or unauthorized access. It encompasses techniques to prevent cyber threats..., allowing for secure and controlled environments to test and learn. Oracle VirtualBox provides an optimal platform to create these virtual environments.
Here’s a step-by-step guide on installing Oracle VirtualBox on Ubuntu.
Pre-requisites:
Ensure that your system meets these requirements:
- Ubuntu 18.04 or above
- Sudo privileges
- Stable internet connection
Step 1: Update your System
Start by updating the package lists for upgrades and new package installations. Open Terminal and type:
sudo apt updateStep 2: Import Oracle VirtualBox Repository
To add the Oracle VirtualBox repository to your system, download and import the repository’s public key with this terminal command:
wget -O- https://www.virtualbox.org/download/oracle_vbox_2016.asc | sudo gpg --dearmor --yes --output /usr/share/keyrings/oracle-virtualbox-2016.gpgAdd the VirtualBox repository using the following command:
sudo add-apt-repository "deb [arch=amd64] http://download.virtualbox.org/virtualbox/debian $(lsb_release -cs) contStep 3: Install Oracle VirtualBox
Update the package lists again, then install VirtualBox:
sudo apt update
sudo apt install virtualbox-6.0Replace ‘6.0’ with the version you want to install. The latest version is 6.1
Step 4: Confirm Installation
Confirm that VirtualBox has been installed correctly by typing:
virtualboxA graphical user interface (GUI) should launch, confirming that VirtualBox is ready for use.
Advantages of Using Oracle VirtualBox in Cybersecurity Learning
- Isolated Environment: VirtualBox allows for the creation of virtual machines (VMs), where you can safely conduct potentially harmful experiments without risking your main operating system.
- Replicate Real-world Scenarios: VirtualBox lets you simulate various scenarios that mimic real-world situations. You can use multiple VMs to create a network of systems, which is great for learning about network security and penetration testing.
- Use Multiple Operating Systems: Cybersecurity often involves handling various operating systems. VirtualBox allows you to run multiple OSs concurrently, which aids in understanding the security mechanisms of each.
- Snapshot Feature: A significant advantage of VirtualBox is its ability to take ‘snapshots’ of a VM. This is essentially a saved state of the VM which you can revert to at any time. It allows you to go back to a known state, useful when studying malwareMalware, short for malicious software, is software specifically designed to harm or exploit digital devices, networks, or services. It encompasses a broad range of harmful software types, including viruses, worms,... or executing tasks that may destabilize the system.
- Cost-effective and Efficient: Oracle VirtualBox is free and open-source. By running multiple VMs on a single physical machine, you save money and resources.
Learning cybersecurity in a safe, controlled environment is crucial, and Oracle VirtualBox provides just that. With it, you can gain hands-on experience, making your learning journey more effective and engaging.
