Snacks and time for discussion afterwards.


Our society increasingly depends on software systems for many vital functionalities. Therefore, exploits resulting from vulnerabilities in the software can cause extensive problems, as recent events have shown. In this talk, I will first attempt to answer the question of whether or not the quality of software is increasing, given the years of intensive effort by the security community. Then, I will proceed to present M-STAR, a new framework developed by our Lab, for assessing the trustworthiness of software components and complex software systems, based on predictions about their future vulnerability rate. I will finish the talk with limitations of the existing work, and opportunities for future research.

Short Bio

I am a doctoral researcher at the Telecooperation lab since May 2016, working as a part of CROSSING collaborative research center. Prior to joining Technische Universität Darmstadt, I obtained my diploma from the School of Electrical and Computer Engineering (ECE) of the National Technical University of Athens (NTUA) in 2016. I am interested in many aspects of computer science including cryptography, computational trust, and network security. My research focuses on applying computational trust in the context of computer security and using blockchain technology for securing trust management infrastructures.
