multi-dimensional data analytics

As more social interaction shifts to the Internet via mobile phones and online social networks (OSNs), new opportunities as well as challenges/problems emerge. For instance, malicious activities involving Android applications are rising rapidly. Spurious user accounts on OSNs can be leveraged to launch a variety of malicious activities (e.g., spam, social engineering). Numerous studies have applied data mining techniques to data collected from network or end-host to extract spatial-temporal patterns or other footprints that can then be used detect malicious behavior or identify the attacker. However, most of the existing solutions analyze a single genre of data source, e.g, traffic traces collected from network, or process running on a host. Our team recognizes that this is no longer adequate, and instead, propose to integrate multi-dimensional data coming from different genre of networks or contexts to profile user and/or application behavior in order to detect malware or suspicious activities. We will leverage data mining, learning & prediction, anomaly detection, and static/code analysis that our team has previously applied successfully to detect network/traffic anomalies and plagiarized mobile applications to uncover new, potentially malicious activities.
