Access control

Wireless cellular networks serve as an essential cyber-infrastructure for mobile users. Unlike the Internet, cellular networks have adopted usage-based charging, rather than the simpler flat-rate charging. Data-plan subscribers have to pay their data bills based on the consumed traffic volume in 3G/4G networks. Although this metered charging system has been operational and generally successful for years, the security study of such a system remains largely unaddressed.

Increasingly medical devices are dependent on software and the wireless channel for their operations, which also pose new vulnerabilities to their safe, dependable, and trustworthy operations. Medical devices such as implantable insulin pumps, which are in wide use today, continuously monitor and manage a patient's diabetes without the need for frequent daily patient interventions. These devices, not originally designed against cyber security threats, must now mitigate these threats.

The economics of Cloud Computing Cloud Computing impels a fundamental shift in how data services are deployed and delivered, enabling flexible, dynamic outsourcing while reducing capital cost commitments for hardware and software. However, cloud computing also deprives customers of direct control over the systems that manage their data, raising security and privacy concerns.

Interoperable, reconfigurable systems of medical devices are the future of medical technology. They will improve care outcomes by catching common mistakes, reduce clinician cognitive workload by suppressing false alarms, and streamline and simplify continued care, especially when patients move between different medical facilities. As the penetration of "smart" networked medical technology increases, we will see increased problems with cybersecurity of such systems.

Data provenance refers to the history of the contents of an object and its successive transformations. Knowledge of data provenance is beneficial to many ends, such as enhancing data trustworthiness, facilitating accountability, verifying compliance, aiding forensics, and enabling more effective access and usage controls. Provenance data minimally needs integrity assurance to realize these benefits.
