The research in our laboratory focuses on addressing the following four key research areas and their interconnections: Cybersecurity, User-authentication, Privacy, and Social-Engineering
OverviewCybersecurity threats and vulnerabilities are causing substantial financial losses for individuals, organizations, and government agencies all over the world. Such cybersecurity landscape can be classified under three major pillars: (a) technology/system, (b) human-computer, and (c) socio-political-organizational (Figure 1). One of the weakest links in the cybersecurity chain has to do with the individuals who are using and protecting such systems. The focus of our Levy CyLab research group is to work on diverse projects related to the human-centric lens of all three cybersecurity landscape pillars. In the technology/systems pillar, user-authentication has long been a challenge due to the overuse of passwords and ease at which they can be guessed or cracked. In the human-computerpillar, employees’ mistakes, due to low cybersecurity competencies and skills represent the majority of cybersecurity threats to organizations. Moreover, non-IT employees have low awareness of the magnitude of cybersecurity threats and their impact on organizations, government, and society. On the other hand, increase complexity for computer systems due to demands for heighten security can cause frustration, resistance, and lower productivity. In the socio-political-organizational pillar, identity theft, social engineering, and insider threats are on the rise, while posing eminent threats to the reputation as well as financial stability of individuals, societies, governments, and organizations. Our research focuses on all three cybersecurity pillars by: (a) development of novel approaches to improve user-authentication with biometrics and multi-factor authentication, including their use in e-learning systems; (b) development of innovative tools to measure cybersecurity skills and reduction of human errors related to cybersecurity; as well as (c) development of state-of-the-art tools to identify insider-threats, programs to help mitigation of social engineering and other cyber threats, along with the protection of privacy and corporate intellectual property, threat mitigation and cybersecurity risk management analysis. Over the last 12 years, our Levy CyLab group has published over 35 papers in refereed publications, one patent application, five grant submissions (one internal $10K grant awarded), four external gifts ($7K total), and 21 doctoral students have completed their dissertation research in these areas.Current Research Our current work continues to focus on the human-centric lens of all three cybersecurity pillars with increased emphasis on the development of state-of-the-art tools and prototype applications to assist in the measurement of cybersecurity skills, identify insider-threats, cybersecurity hygiene, along with experimental studies to assist organizations with: business e-mail compromise (BEC), social engineering, cyber threat mitigation, improve business continuity plans and resilience, as well as cybersecurity risk management.
