Abstract:

For decades, Computer and Information Security studies have been driven by core concepts such as Confidentiality, Integrity, and Authentication. What would be the core concepts that will drive the study of the emerging discipline of Cybersecurity? In this talk, I will present the novel concept/abstraction of Cybersecurity Dynamics, which we believe will formulatethe ultimately-wanted foundation for the emerging Science of Cybersecurity. Cybersecurity Dynamics is an extremely multidisciplinary and interdisciplinary approach to tackling some real-world problem of the highest importance. I will start with a conceptual exploration, and highlight some preliminary results (with emphasis on high-level ideas) toward the ultimate goal by exploiting mathematical techniques such as Dynamical Systems, Stochastic Processes, Control Theory, Game Theory, and Network Science. I will discuss some inherent technical barriers that must be adequately addressed but seem to go beyond the reach of existing mathematical techniques (i.e., new techniques/skillsare needed in order to achieve the ultimate goal). Please refer to http://www.cs.utsa.edu/~shxu/socs/index.htmlfor more information about this exciting research endeavor.Part of this talk is based on joint works with Professor Wenlian Lu and his group at Fudan University. We hope to attract talented students to join this exciting research endeavor of highest originality.

摘要：网络空间是一个人造的，虚拟的“宇宙或者社会”系统。它已经全面融入人们生活及其它各个方面。但是，人类智慧在设计如此复杂的系统时的能力是非常有限的8️⃣，更何况最初的设计目标只是为了让少量可信赖的人群来使用它。这就是为什么网络空间会有如此多的原生的安全问题以及由此带来的各种有利于攻击方的非对称性⚠，而人们的直接感受就是绵绵不断的关于系统被攻破导致的数据泄漏的报道或者你自己的计算机被恶意代码肆意地侵入👸。什么样的理论基础可以用来有效地，全方位地描述这个复杂系统中的安全问题及现象（就像物理科学描述宇宙那样）🧝🏽‍♀️，从而可以极大地或者最大地改变网络空间安全的现状？这是我们想要解决的根本问题。我们将以半科普的方式来展开这个根本的问题和我们的研究蓝图。报告的部分内容是基于和杏悦娱乐数杏悦卢文联教授的合作研究成果🙋🏿‍♂️，我们因此希望这个报告能激起有才华有抱负的同学（包括本科生）的研究兴趣，从而加入到这个新兴的、激动人心的🥅、又高度原创的研究领域中来🧑🏽‍🚒。

Shouhuai Xu is a Full Professor in the Department of Computer Science, University of Texas at San Antonio. He is the Director of the Laboratory for Cybersecurity Dynamics (http://www.cs.utsa.edu/~shxu/LCD/index.html) at UTSA. His research is primarily in making cyberspace more secure and trustworthy. He is especially interested in mathematical modeling and analysis of cybersecurity, and devising practical cyber defense technology that include both provably-secure cryptographic protocols and advanced cyber defense mechanisms. His research has been funded by AFOSR, ARO, NSF and ONR. He is a Program Committee co-chair of NSS’15 and was a Program Committee co-chair of Inscrypt’13. He has served on the Program Committees of 90+ international conferences/workshops. He is currently an Associate Editor of IEEE Transactions on Dependable and Secure Computing (IEEE TDSC) and IEEE Transactions on Information Forensics and Security (IEEE T-IFS). He earned his PhD in Computer Science from Fudan University.
