The evolution of computer systems has changed radically our everyday lives. Unfortunately, despite the many technological advances, computer systems remain vulnerable to attacks. The vulnerabilities are often connected to the systems’ intrinsic mechanics and not to human mistakes. Offering protection to such vulnerable systems is key for enabling their functionality safely. In this talk, I will first introduce the basic principle of countering attacks through hardening. In essence, I will discuss how hardening, compared to traditional security approaches, moves the focus from repairing the vulnerabilities to reducing the benefit of attackers. Second, I will discuss how systems can be hardened against attacks. For this, I will elaborate on how hardening can transform vulnerable systems to withstand exploits or even entire compromising. Finally, I will discuss how the attack surface can be further explored, despite hardening in place. In the entire talk, for demonstrating the real applications of hardening, I will use two major attack domains: (a) software exploitation and (b) database leaks.

Short Bio:
Elias Athanasopoulos is an assistant professor in Computer Science with the University of Cyprus. He received his BSc in Physics from the University of Athens and his Ph.D. in Computer Science from the University of Crete. Before joining University of Cyprus, he was an assistant professor with Vrije Universiteit Amsterdam and member of VUSec. Elias was a Microsoft Research PhD Scholar, as well as a Marie Curie fellow with Columbia University and FORTH. His research interests are system security and privacy. He has several publications in all major systems and system security conferences and journals, such as IEEE Security and Privacy (Oakland) and IEEE European Security and Privacy, ACM CCS, Usenix Security and ATC, NDSS, EuroSys, and ACM TOPS.

This colloquium is part of the speaker's procedure for evaluation and promotion from Assistant Professor to Associate Professor.
