Hello, and welcome back in part 2. It’s been a few days and not have any time update about install and hardening your Linux (Ubuntu) virtual machine. So, without wasting any time, let’s go.
Virtual Machine with Ubuntu
The most important things that I need to highlight is please always using the latest stable TLS. TLS is stand for “Long Term Support”. Version 20.04 is expected to receive support until April 2024. By time of this article written the stable version ubuntu is 20.04. The assumption that I need to make right now if your follow my previous article than you already download the ISO file and create your first VM. If you not, you can make any VM for the first time by follow these steps below.
- Open virtual box software
- Provide a name to virtual machine as you like
- Select the folder destination where you want to install/save the VM
- Select the “type” for “Linux”
- Choose “version” to “Ubuntu (64-bit)
- Click “next”
The next step is after you load the ISO file, it’s time to install out Ubuntu.
- Starts by select click “star” on the VM name that you create before
- Select “Install Ubuntu”
- Choose your desire language then click “continue”
- Choose “normal installation”, “download updates”, “install third party” and click “continue”
- Select “Erase disk and install Ubuntu”
- Choose “Install now” and click “Continue”
- Enter your time zone and select “Continue”
- Enter your username, password as your desired
- Select “Login automatically” and “Continue”
- Wait until your Ubuntu installation complete
- Select “restart now”
- After a while your Ubuntu machine is reboot automatically. There are more steps to finish the installation.
- Choose “Skip” then “next”
- There is an option to improve Ubuntu choose “No”
- Select “next” then “done”
Now all the step is complete and you can login into Ubuntu using username and password that you’ve created before. If there is prompt to install update choose “remind me later”. I can say that now you have working Ubuntu machine installed and ready to use.
Setup Security and Privacy
The next step is to set the setting for security and privacy for our Ubuntu. It is also important to always update your software. You can just launch the terminal and using command line but there is way that really simple. Find software “Software Updater” and add it to favorites so you can launch it by the desktop. Below are the steps that you can follow to harden out security and privacy
- Run command on terminal “sudo apt purge -y apport”
- “sudo apt remove -y popularity-contest”
- Go to “setting” and click tab “privacy”
- “File history & trash” disable all the options
- Disable all option on “screen lock”
- Set “diagnostic” to “never”
- Disable “location service”
Conclusion
Using VM to run your OSINT investigation can really helpful. There are a lot of features that really cool by using the VM include cloning or snapshot but that’s going to be my next article. See you 😊
