Why take this course?


When it comes to open-source, the sky is the limit!

In a nutshell, you will build a company-like network with headquarter and branch office on Unix-like OSs and open-source tools, then try to hack its vulnerabilities.

From switches to endpoints, clustered firewalls, servers incl. Network Access Control, shortly NAC server, jumpers, and anything else are all built on a flavor of Linux OS such as openSUSE, AlpineLinux, Debian, Ubuntu, etc., or a Unix-like OS such as FreeBSD.

Network security should be embedded into the nature of the corporate's network and that is what we learn in this course.

We do not care much about vendors and logos, but practical concepts. For example, we dive into Shell commands, TCP/IP and networking fundamental concepts, and core network security principles using open-source, yet industry-proven products.

We aim to teach you how standard networking concepts are "designed" and are also "applied" in work environments.

Why a pure Linux-based network? Besides the fact that Linux runs the world, if you learn the secure networking using Linux, Unix, and open-source tools, you will feel pretty confident about their commercial equivalents. For example, if you learn network firewalling using iptables and nftables, you won't have any issues with Cisco FirePower, FortiGate, or Juniper firewalls.

As said, we are not into vendors, we are interested in standardized theoretical concepts and practical technics. This method will give you a firm conceptual understanding of underlying technologies and ideas about how finished products like Cisco switches, Fortigate Firewalls, Cisco ISE NAC, HPE Aruba, and so on, actually work behind the scene.

In the end, you will run the most common network attacks using Kali Linux against the network you built yourself.

Unique content! I'm watching the last section where network layer 2 and 3 protocols that are built in previous lectures are being tested against network attacks... this is really amaizing how the course structure is thought and built.

The instructor is extremely attentive to accuracy and deep details. The course content is unique. It opens my eyes about what is going on behind the scene in Open Source and Linux technologies. In terms of network security, the content is very practical. It is geared towards techs used in many businesses and corporate networks. Overall, I highly recommend this course. It is a small simulated project for companies' networks formed by open source products.

Are you serious? man this is the next level training! Since even I was waiting for such a smooth and flawless training, where I can develop a project, end to end over Linux and open source tools. I learn all the concepts via free open souce tools, also I feel I'm professionally building a secure network for a corportate with no pressure at all! You guys have outdone yourselves!!! Thank you, thank you!

It is worth every penny of it! Very deep and useful. For me, especially the keepalived clusting part is very interesting, where I failover a Linux machine and the other Linux jumps and take over all VLAN IPs and other networking information very smoothly. Loved it! Offensive packet capture part has also a nice perspective on packet analysis in real work environment. All in all, a very informative course! It is a must-have, if you look for a real network and linux engineering course. Thank you Miris!
