The best way to understand cloud vulnerabilities is to combine continuous monitoring with a multi-layered testing approach and contextual analysis of risk. You should start by using automated tools like vulnerability scanners and Cloud Security Posture Management (CSPM) to identify known issues, then perform penetration testing to find weaknesses.

Crucially, analyze vulnerabilities based on business context and threat actor motives to prioritize those with the highest potential impact.

I am a Professor and the Associate Chair for Research in the Department of Information Sciences and Technology at George Mason University, and I serve as the Executive Director of the Institute for Digital Innovation (IDIA) and the Director of the Center for Infrastructure Security in the Era of AI (ISEAI). I received my Ph.D. degree in Computer Science and Engineering in 2005 from the University of Naples Federico II. In 2011, I joined George Mason University after serving as a Postdoctoral Researcher at the University of Maryland, College Park.

My research interests are in the area of Information and Network Security, with a particular emphasis on Modeling and Detection of Cyber Attacks, Cyber Situational Awareness, Network Hardening, Moving Target Defense, Configuration Security, and Vulnerability Metrics. I have participated in sponsored projects totaling $13M, with my personal share amounting to $3.5M. I hold six U.S. patents and have co-authored two books as well as over 90 publications in peer-reviewed journals and conference proceedings. In 2014, I was honored as one of the three recipients of the Mason Emerging Researcher/Scholar/Creator Award, one of the most prestigious honors at Mason.

I have served on the technical program committee of numerous conferences and am a member of the Editorial Board of Springer International Journal of Information Security, Elsevier Co
