Introduction to B2BR

The Born2BeRoot project entails the setup of a minimal server environment. The virtual machine (VM) won't have a Graphical User Interface (GUI) except the terminal and will have security measures in place. Participants must adhere to specific rules outlined in the project description.

Mandatory Part

The mandatory part of the project involves setting up a VM with specific requirements, including:

• Installing Debian or Rocky on a virtual machine platform (VirtualBox or UTM)
• Setting up encrypted partitions using LVM.
• Configuring SSH service on port 4242.
• Implementing a firewall (UFW for Debian, firewalld for Rocky) allowing only port 4242.
• Implementing a strong password policy
• Implementing sudo user management
• Creating a script (monitoring.sh) that displays system information every 10 minutes after startup time.

Bonus Part

The bonus part offers additional tasks: setting up partitions in a particular structure, creating a functional WordPress website, and setting up a custom service. Bonus tasks are evaluated only if the mandatory part is completed perfectly.

I chose keyboard-configuration as my custom service, since this package simplifies the process of changing the keyboard layout in case evaluators have different preferences.

Submission and Peer-Evaluation

Finishing the project requires submitting a repository with only a signature.txt file containing the signature of the virtual machine's virtual disk. This is followed by three 1-hour evaluations where the server is tested and where the examinee needs to explain every step of their setup.

Scripts

• monitoring.sh: Script for displaying system information.
• sleep.sh: Script for setting the execution of monitoring.sh to the correct time.

With the following cronjob, the monitoring message will then be shown every 10 minutes after startup, as required by the subject:

*/10 * * * * bash /path-to-script/sleep.sh && bash /path-to-script/monitoring.sh
