About the Author

Stefan Umit Uygur has been an IT System and Security engineer for 14 years. He is an extremely motivated open source software evangelist with a passion for sharing knowledge and working in a community environment. He is highly experienced in Penetration Testing and Vulnerability Analysis, Management, and Assessment. He has been involved in many open source software projects, for example BackBox, where he is part of the core team. He has helped to promote the free software culture around the world by participating and organizing international conferences. He significantly contributes to shedding the false and negative perceptions around hacking and hackers by promoting the hacker world in a positive light. He explains in detail the real world of hacking, hackers' motivations, and their philosophy, ethics, and freedom. These activities are promoted mainly through national and international magazines, and in particular, during the conferences that he participates. Along with his professional activities, he has contributed to the Linux magazine, the PenTest magazine, and a few other small, periodic, technical publications.

However, his main passion is continuous collaboration with the community as he believes in the community more than anything else. He strongly feels that knowledge shouldn't be owned by a few people, but should be the heritage of the entire collective. He is always grateful to the community for the skills and the knowledge he possesses. One of the definitions he gives to the community is that it is the real school and university where one truly learns.
