It covers key topics such as virtualization, partitioning, LVM, command-line tools, SSH, and system security measures like sudo, firewalls, and password policies. The project repository includes a script for automated tasks and the virtual machine signature.

During the evaluation, I was asked questions about the topics below;

• Choose between two Linux-based operating systems: Rocky or Debian;
• Create at least 2 encrypted partitions using LVM;
• Ensure SSH services are running on specific ports;
• Configure a UFW firewall and leave only port 4242 open;
• Set up the hostname (will be changed during evaluation) and a strong password policy for all users;
• Set up a strong sudo configuration;
• Create a monitoring script that displays specific information every 10 minutes at server startup;

BONUS

During the evaluation, also had to justify my choices;

• Set up a different partition structure;
• Set up a functional WordPress website with the following services: lighttpd, MariaDB and PHP;
• Set up a service of my own choice that I think is useful (justify that choice);
