Attacks and intrusions to information systems cause large revenue losses. The prevention of these attacks is not always possible by just considering information from isolated sources of the network. A global view of the whole system is necessary to react against the different actions of such an attack. The design and deployment of a decentralized system targeted at detecting as well as reacting to...
Confidentiality is one of the most important topics in computer security research. In order to check and ensure confidentiality, information flow models are widely used. These models support the specification of valid flows of information. Furthermore, they provide means to formally check whether a given system fulfills a certain security property within this model. In this paper, we propose an information...
Our vision is driven by rapid progress in hardware development, such as miniaturizing computing devices. On the software side, however, application development for such a setting is challenging for several reasons. One is the heterogeneity of devices and networking technologies, which vastly increases application development complexity. Other reasons include frequent reconfigurations and communication...
The cooperation between the different entities of a decentralized prevention system can be solved efficiently using the publish/subscribe communication model. Here, clients can share and correlate alert information about the systems they monitor. In this paper, we present the advantages and convenience in using this communication model for a general decentralized prevention framework. Additionally,...
