I'm Coen Goedegebure, a Dutch software developer, architect and also mentor, scrum master and security enthusiast.
After receiving my BSc. degree in Advanced Computer Science at Avans College in Breda, I earned a MSc degree at the Radboud University Nijmegen (Faculty of Science) while doing parallel studies on Psychology and Philosophy at different faculties. This diversity was fueled by my wide interest in a variety of fields and topics, which lead to me being the generalist I am today.
Now, having more than 15 years of professional experience as a software engineer, I have worked internationally for customers in The Netherlands, France and Italy. The domains in which these companies operate, span from banks, insurance companies, logistics, flower and seed breeding to the Royal Netherlands Army, high-tech embedded and video surveillance systems and helicopter manufacturing and design; each having their own interesting challenges and targets.
For the last 7 years I am a member of the Management Team Operations of NCIM, the company I work for, and mentor a group of around 10 other software professionals in their careers.
Several years ago I discovered my passion for everything related to IT security and started absorbing the knowledge in my spare time. I did this by reading books, articles and writeups, practicing with online and offline labs, following courses online and classroom-style like SANS SEC560 (Network Penetration Testing and Ethical Hacking) and competing in (and organizing) CTF tournaments like the SANS Core NetWars Tournament. In the latter I achieved 3rd place which earnt me a coveted NetWars coin.
As a public speaker I gave Ethical Hacking presentations, workshops and live demonstrations at events like the Dutch Cyber Conference, companies such as the Ministry of Defense, ABN AMRO and Rijk Zwaan and different meetups like /dev/070 and DevSec.
Over the years I have done quite some research on different topics, which lead to a collection of code snippets and concepts. As research continues I have started this blog to have this information published and in one place. Who knows, I might even be able to help a few people on the way!
