Networks are where most real attacks play out, and this course teaches you to exploit and defend the components that hold them together. You work through both the theory and the hands-on techniques ethical hackers use against DNS, DHCP, routers, encryption protocols and applications exposed over the network.
You start with the attacks themselves: <strong>denial of service, MAC spoofing, ARP-based man-in-the-middle, and credential theft</strong>. From there you move into DNS spoofing and tunneling, IPv6 protocol exploitation, DHCP starvation and rogue DHCP, router compromise, and breaking weak encryption.
<h3>Write your own tools and exploits</h3>
What sets this course apart is that you don’t just run pre-made tools. You <strong>code your own hacking tools in Python</strong> to automate attacks, and you write an exploit from scratch against a vulnerable network application, using the <strong>gdb debugger to reverse engineer</strong> it and build a working reverse shell. This is the skill that separates operators who understand what they’re doing from those who only run scripts.
The course gives equal weight to defense. You learn to detect ARP spoofing, write custom <strong>IDS/IPS rules in Snort</strong>, apply drop rules for active prevention, and harden router settings against unauthorized access.
A bonus networking section covers the fundamentals from the OSI model and encapsulation to IPv4, IPv6, subnetting, ports, ARP and DNS, so you can fill any gaps as you go. By the end, you will be able to attack the core components of a network, build custom Python tooling and exploits to do it, and put defensive controls in place to stop the same attacks.
