This Python Network Programming course is aimed at network professionals having little or no experience in network security and a great desire to use Python and Scapy to build various network security tools for their network. This hands-on Python Network Programming training walks you through lots of scenarios, attacks and useful tools to help you get started with network security.

If you are already a network security professional or penetration tester, then this course might not be for you!

What’s so special about this course?

Well, let me tell you what's this course all about:

  • Learning to use the amazing Scapy module and all its capabilities.
  • Building network attacking and scanning tools and testing them against Windows / Linux / Cisco targets.
  • Building your own (basic) version of NMAP and scanning Windows / Linux hosts.
  • Performing various small network tests and operations using the Scapy interpreter.

Still not enough for you? Let me describe a few more features of this course:

  • More than 20 scripts for you to download and use right away, for free.
  • An amazing optimized Linux Ubuntu VM, with all the tools, modules and dependencies already installed.
  • Quizzes and a final network security project for you to build and implement in your test lab/network. Also, the solution for the project is explained and tested.
  • 1080p, Full HD videos. Improved audio quality.
  • 115+ lectures and counting. 4.5+ hours of content.
  • Concise and focused lectures. Straightforward configuration of devices. Less software and operating system complications. Less code to write and troubleshoot.

Equipped with full working scripts (in .py format) and an amazing virtual machine, you will be able to work alongside me on each lecture and each application. I will provide the full code for each application, so you can save time and start coding and testing on the spot.

Warning! All the information, concepts and code in this course should be used in isolated, test environments and for learning purposes only. Otherwise, you may be accused of criminal activities, according to the law.

Important prerequisites before you enroll:

  • You should already be familiar with networking concepts like: TCP/IP, UDP, OSI Layers, Packets, Frames, ICMP, ARP, DHCP, VMs (Virtual Machines).
  • You should already be familiar with Python syntax: functions, if, for, while, string and file operations etc. If you have no experience whatsoever in Python, then I encourage you to also check out my "Python Network Programming - Part 1: Build 7 Python Apps" course, which teaches Python from scratch and then dives into using it on network devices, by building some great network apps.
  • For running the Ubuntu 15.10 Virtual Machine I provide, dedicating 2 GB of RAM will be more than enough.
  • You won't have to buy anything else. I am going to use only free software throughout the course: VirtualBox, Linux, free VM etc.

Important information before you enroll:

  • In case you find the course useless for your career, don't forget you are covered by a 30 day money back guarantee, full refund, no questions asked!
  • Once enrolled, you have unlimited, lifetime access to the course!
  • You will have instant and free access to any updates I'll add to the course.
  • Check out the curriculum and free preview lectures for a quick insight.

So, what are you waiting for? Do you want to start your network security journey?
