A network intrusion hyperalert is an aggregation of related alerts. Several different intrusion alerts may be related to one attack. The reasoning power pertaining to alerts is increased if these related alerts can be integrated into one construct, the hyperalert. Having a history of alerts/attacks, we propose a genetic algorithm approach to determine “interesting” aggregation of such alerts an...

We report a study that examines performance of pilots flying a simulated UAV in a highfidelity environment while using different types of perfect and imperfect automation aids. Fiftysix student pilots carried out simulated UAV missions containing a 3D view of terrain, a 2D topdown navigational map, system parameter gauges, and a message box. Trajectory and manipulation of a 3D camera was contro...

OBJECTIVE A variety of postmarketing surveillance strategies to monitor the safety of medical devices have been supported by the U.S. Food and Drug Administration, but there are few systems to automate surveillance. Our objective was to develop a system to perform real-time monitoring of safety data using a variety of process control techniques. DESIGN The Web-based Data Extraction and Longit...
