I aim to eventually publish all my lectures online on my YouTube channel.
A sample of my work, a crash course on the topic of Information Security, is available on YouTube (lecture is in English):
Introduction to Computer Security – this lecture is an introduction to the field of Computer Security. While the eventual course covers many (if not all) of the CISSP domains, the lecture focuses on explaining the key security concepts of ‘people, processes and technology’, ‘prevention, detection and mitigation’, etc. in layman’s terms – students sometimes come from completely different disciplines.
Console Hacking – this lecture gives an overview of the principles behind the hacking of embedded devices, using the most popular game consoles of the past 20 years or so as examples. An updated version was presented at the 2015 FSEC conference in Varaždin, Croatia.
