A. Abhishta (Abhishta)

PhD Candidate

About Me

I am a PhD. candidate at the Industrial Engineering and Business Information Systems group at University of Twente, The Netherlands.

I see myself as a researcher who helps businesses understand the need for investment in cyber security. My research might answer the question that for long has been unanswered: “Will investment in cyber security let me sell more products?” I work on analyzing the economic impact of distributed denial of service attacks on businesses. My research is part of the NWO project D3 – Distributed Denial-of-Service Defense: protecting schools and other public organizations.

Apart from research I am also interested in teaching and guiding students. I give lectures on risk management and cyber security investment decisions in multiple courses at the university. I am always interested to talk about globalization and it’s impact on the society. You are most welcome to go through the publications page to have a look at my research work and lectures.
