This project studies Internet censorship using novel measurement techniques, ranging from low-level packet filtering on Internet Protocol (IP) networks to high-level censorship of social media content. Collectively these techniques can provide greater situational awareness of censorship dynamics. The project focuses on a suite of advanced inference techniques for when ?direct observation?

This project tackles the social and economic elements of Internet security: how the motivations and interactions of attackers, defenders, and users shape the threats we face, how they evolve over time, and how they can best be addressed. While security is a phenomenon mediated by the technical workings of computers and networks, it is ultimately a conflict driven by economic and social issues that merit a commensurate level of scrutiny.

This project studies the security of representative personalized services, such as search engines, news aggregators, and on-line targeted advertising, and identifies vulnerabilities in service components that can be exploited by pollution attacks to deliver contents intended by attackers.

Robust cybersecurity information sharing infrastructure is required to protect the firms from future cyber attacks which might be difficult to achieve via individual effort. The United States federal government clearly encourage the firms to share their discoveries on cybersecurity breach and patch related information with other federal and private firms for strengthening the nation's security infrastructure.

The threat and impact of cybersecurity breaches are felt throughout society with massive financial losses to businesses and breach of national secrets. Human behavior is increasing seen as a fundamental security vulnerability that is at the center of many security breaches. Several approaches have been used for improving user security behavior, including enacting information security policies, providing security awareness training, and introducing penalties for security violations; these approaches have not been very effective.

The world increasingly relies on computer systems and associated software, yet attackers continue to exploit vulnerabilities in this software to threaten security in new and sophisticated ways. This research views exploitations of software vulnerabilities as critical, but not unique, examples of innovations that society would like to discourage? many other examples (e.g., biological weapons, sports doping, terrorist devices, privacy intrusions) exist.

This research is building an understanding of what data is useful to attackers and what data is private for its legitimate owners so that security systems can incorporate these values into a data-driven, defense-in-depth approach to securing our digital lives. We are exploiting the fact that both users and attackers must sift through vast amounts of data to find useful information.

As cyber-socio-physical and infrastructure systems are increasingly relying on data and integrating an ever-growing range of disparate, sometimes unconventional, and possibly untrusted data sources, there is a growing need to consider the problem of estimation in the presence of strategic and/or self-interested sensors. This class of problems, called "strategic information transmission" (SIT), differs from classical fault-tolerant estimation since the sensors are not merely failing or malfunctioning, but are actively trying to mislead the estimator for their own benefit.

Online social networks, such as Facebook, Twitter, and Google+, have become extremely popular. They have significantly changed our behaviors for sharing information and socializing, especially among the younger generation. However, the extreme popularity of such online social networks has become a double-edged sword -- while promoting online socialization, these systems also raise privacy issues.
