Hands-On Networking: Building a Secure Network

Are you tired of reading about network security and never actually getting to try it out for yourself? Do you want to learn how to build a secure network from scratch? Look no further than Hands-On Networking!

At Hands-On Networking, we believe that the best way to learn is by doing. That's why we've created a series of labs that will guide you through the process of building a secure network step-by-step. In this article, we'll give you a sneak peek into what you can expect from our labs.

Lab 1: Setting Up Your Environment

The first step in building a secure network is setting up your environment. In this lab, you'll learn how to set up a virtual machine using VirtualBox and how to install Ubuntu Server on it. You'll also learn how to configure your network settings and how to connect to your virtual machine using SSH.

Exciting, right? But wait, there's more!

Lab 2: Configuring Your Firewall

Once you've set up your environment, it's time to start securing it. In this lab, you'll learn how to configure your firewall using UFW (Uncomplicated Firewall). You'll learn how to allow and deny traffic based on specific ports and protocols, and how to create custom rules to meet your specific needs.

But that's not all! You'll also learn how to configure your firewall to block incoming traffic from specific IP addresses and how to log your firewall activity.

Lab 3: Setting Up a VPN

Now that your firewall is up and running, it's time to set up a VPN (Virtual Private Network). In this lab, you'll learn how to set up OpenVPN on your Ubuntu Server and how to configure your firewall to allow VPN traffic.

But why do you need a VPN, you ask? A VPN allows you to securely connect to your network from anywhere in the world. It encrypts your traffic, making it impossible for anyone to intercept your data. Plus, it allows you to access resources on your network that might not be available from outside your network.

Lab 4: Configuring Your DNS Server

In this lab, you'll learn how to set up a DNS (Domain Name System) server using BIND (Berkeley Internet Name Domain). You'll learn how to configure your DNS server to resolve domain names to IP addresses and how to create custom DNS records.

But why do you need a DNS server, you ask? A DNS server allows you to easily access resources on your network using domain names instead of IP addresses. Plus, it allows you to create custom domain names for your network resources.

Lab 5: Setting Up a Web Server

Now that your DNS server is up and running, it's time to set up a web server. In this lab, you'll learn how to install and configure Apache, the most popular web server on the internet. You'll learn how to create virtual hosts to host multiple websites on a single server and how to secure your web server using SSL/TLS certificates.

But why do you need a web server, you ask? A web server allows you to host websites and web applications on your network. Plus, it allows you to control access to your websites using authentication and authorization.

Lab 6: Configuring Your Email Server

In this lab, you'll learn how to set up an email server using Postfix, the most popular mail transfer agent on the internet. You'll learn how to configure your email server to send and receive emails and how to secure your email server using SSL/TLS certificates.

But why do you need an email server, you ask? An email server allows you to send and receive emails on your network. Plus, it allows you to control access to your emails using authentication and authorization.

Lab 7: Monitoring Your Network

Now that your network is up and running, it's important to monitor it to ensure that it's secure and performing optimally. In this lab, you'll learn how to use tools like Nagios and Cacti to monitor your network's performance and how to set up alerts to notify you of any issues.

But why do you need to monitor your network, you ask? Monitoring your network allows you to detect and resolve issues before they become major problems. Plus, it allows you to optimize your network's performance to ensure that it's running at peak efficiency.
