Gökhan Bal is a digital security enthusiast since 2007. Back then, emerging cyber attacks and data breaches made him realize that there will be no sustainable digitalization without robust security in the core of IT infrastructures. Being in the middle of his Computer Science studies at Goethe University Frankfurt, he set sail to the profession as an IT security expert and focused on topics like information security, computer networks and distributed systems. Gökhan gained his diploma in Computer Science (Diplom-Informatiker) in 2009 with the completion of a thesis about enhancing web browser security and privacy by using Trusted Computing capabilities (TPM) at the Fraunhofer Institute for Secure Information Technology in Darmstadt. Amazed by the work on cutting-edge topics, in 2009 he decided to continue the academic pathway as a research and teaching assistant at the Chair of Mobile Business and Multilateral Security at Goethe University Frankfurt. Beyond his contributions to multiple EU-funded research projects, he researched on security and privacy issues on mobile platforms and completed his PhD in 2015 with a contribution to effective privacy risk communication in smartphone app ecosystems. Parts of his PhD work he performed during a research visit in 2013 at the renowned School of Computer Science at Carnegie Mellon University in Pittsburgh, PA.
Since then, digital security is a mission and a story to tell for Gökhan. He follows this mission in multiple ways:
In 2015 Gökhan followed the quest for making real-life contributions to digital security that affect many people. He started at the Deutsche Bahn group as an information security expert where he contributed to the cyber security strategy and to the enhancement of the companies' cyber defense capabilities. Since 2018 Gökhan is working at DB Systel, the internal IT service provider of Deutsche Bahn, where he is following up on his mission to enhance the capabilities of Deutsche Bahn to detect and respond to cyber attacks.
Digitalization has just begun. In future, there will be a high demand for people with the right expertise and mindset to inject security into digital innovations. That motivates Gökhan to contribute to the education of the required skilled people. He gives lectures and seminars on digital security and privacy to various student audiences ranging from computer science, business administration & economics and psychology.
As a digital security enthusiast who loves to contribute to peoples' security in all contexts of life, Gökhan founded the digital security blog "cyber & resistant" (cyberandresistant.de) in 2017 following the mission to empower people for resistance against cyber threats. While motivation and empowerment is the goal, positivity is a key character of the blog.
