cs colloquium

“Smartphones (Android 2) in Foreign Wars: Locking Down Linux, Dalvick, Software Apps and Accessories”
Dr. Jeffrey Voas, National Institute of Standards and Technology
Dr. Angelos Stavrou, George Mason University

Presented in conjunction with the IEEE Reliability Society

Recent advances in the hardware capabilities of mobile hand-held devices have fostered the development of open-source operating systems for mobile phones. These smartphones are powerful enough to accomplish most of the tasks previously requiring at least a personal computer. This talk will discuss the cyber threats that stem from these new smart device capabilities and the online application market for mobile devices, including malware, data exfiltration, exploitation through USB, and user and data tracking.

We will present the ongoing NIST/GMU effort to defend against or mitigate the impact of attacks against mobile devices by analyzing the source code and binaries of mobile applications, hardening the Android kernel, using kernel network and data encryption, and controlling the communication mechanism for synchronizing user content with computers and other phones. This talk will also explain the enhanced difficulties in dealing with these security issues when the end goal is to deploy security-enhanced smartphones into combat settings.

Jeff Voas is a computer scientist at the National Institute of Standards and Technology, director of IEEE Division VI, past president of the IEEE Reliability Society and an IEEE fellow. He holds a PhD in computer science from the College of William and Mary. More details at

Angelos Stavrou is an assistant professor of computer science at George Mason University. He received his PhD from Columbia University. His research interests are large systems security and survivability, intrusion detection systems, privacy and anonymity, security for MANETs and mobile devices. More details at
