Much work has been conducted to investigate the obstacles that keep users from using mitigations against security and privacy threats on smartphones. By contrast, we conducted in-depth interviews (N = 19) to explore users’ motivations for voluntarily applying security and privacy actions on smartphones. Our work focuses on analyzing intrinsic motivation in terms of psychological need fulfillment....
The Android OS has a permission-based security system that controls the third party applications' access to sensitive information on the smartphone. The risk evaluation is left to the user who has to evaluate whether or not the requested permissions are appropriate. However, former work has shown that users lack attention to and understanding of the permissions which makes it difficult for them to...
This paper discusses the training aspect of the EMILI Simulation and Training environment (EMILI-SITE), a prototype system aimed at emergency management in critical infrastructures like airports, railway/metro systems, and power grids. As emergency procedures and standards are usually defined in advance, they are an interesting application case for the complex event processing / event-condition-action...
Wireless sensor networks are used for monitoring phenomena using spatially distributed sensor nodes. A wireless sensor network may be far away from a server which collects and processes data from the network. In that case, one or more gateways are used to connect the network to the remote server via TCP/IP or UDP/IP. To speed up testing and deployment of a network, we have developed a simulator which...
This paper describes a novel approach to situation awareness and management in critical infrastructures using an emerging Complex Event Processing paradigm in combination with ECA (Event Condition Action) rules. Every modern infrastructural facility, especially critical ones, would want to catch or predict exceptions and threats at the earliest possible moment. The crucial prerequisite for this is...
This article introduces a decision support system for determining a safe and short (in both time and distance sense) evacuation path and for increasing situation awareness in the case of a hazard in buildings of large critical infrastructures (CIs). CIs are infrastructures that are complex, difficult to monitor and with an integrated SCADA system, such as airports or metro stations. The FP-7 project...
