**Debian 12: A Step-by-Step Guide to Configuring Your System**

In this part of our series, we delve into configuring Debian 12 for optimal performance. We start by installing Uncomplicated Firewall (ufw), a user-friendly firewall management tool that provides fine-tuned control over incoming and outgoing traffic.

Next, we explore NetworkManager, which simplifies network configuration and setup. We install NetworkManager and connect to our home Wi-Fi network using the terminal user interface (nmtui).

However, it's essential to note that NetworkManager is more suitable for desktop use than server management. For servers, default networking services like ufw are recommended.

Throughout this process, we emphasize the importance of maintaining a secure system by configuring firewalls and avoiding unnecessary port openings.
