The Internet has become an integral part of everyday life. The great benefits of the Internet also come with potential risks, security issues, and privacy concerns. Internet security products are usually employed to inform users about security incidents.

Insiders pose substantial threats to an organization, regardless of whether they act intentionally or accidentally. Because they usually possess elevated privileges and have skills, knowledge, resources, access and motives regarding internal systems and data, insiders can easily circumvent security countermeasures, steal valuable data, and cause damage. Perimeter and host-based countermeasures like firewalls, intrusion detection systems, and antivirus software are ineffective in preventing and detecting insider threats.

News reports are rife with accounts of data breaches, network security problems, and the dangers of keeping personal information online. Modern life, though, makes it impossible to avoid doing just that. It is almost no longer a choice whether we make purchases, communicate with our bank, apply for government services, or file our taxes online - it is the standard expectation. This research explores how people resolve the tension between these two realities and the practices that people have adopted to balance competing demands upon them.

Risk communication is an important part of many cyber security mechanisms. Android's current risk communication mechanism is based on security warnings and has been demonstrated to be ineffective because users become habituated to ignore such warnings and tend to consent to all prompts. This multi-disciplinary research project aims at developing holistic solutions to usable risk communication and control for the Android platform.

The critical role of spectrum as a catalyst for economic growth was highlighted in the 2010 National Broadband Plan (NBP). A challenge for the NBP is realizing optimal spectrum sharing in the presence of interference caused by rogue transmissions from any source, but particularly secondary users who share the spectrum. This complex problem straddles wireless technology, industrial economics, international standards, and regulatory policy.
