Especially throughput and latency are directly influenced by the dimension of packet queues. Determining the optimal dimension based on the inevitable tradeoff between throughput and latency tends to be a hard, almost infeasible challenge. Several algorithms for Active Queue Management have been proposed to address this challenge over the last years. However, the deployment and by that the development of such algorithms is challenging as they are usually located within the operation systems’ kernel or implemented in fixed hardware. In this work, we investigate how novel algorithms can be deployed in user space for rapid prototyping with tolerable effort. We provide core performance characteristics and highlight the viability and reasonability of this approach.","PeriodicalId":115235,"journal":{"name":"Electron. Commun. Eur. Assoc. Softw. Sci.

There currently exists no solution for organizations to access current trends and intelligence to understand emerging threats and how to appropriately respond to them.  This research project delivers I-WARN to help bridge that gap. Using a wide range of open-source information, I-WARN gathers, analyzes, and reports on threats related to the theft, fraud, and abuse of Personally Identifiable Information (PII). I-WARN then maps those threats to the MITRE ATT&CK -- a framework that helps understand lateral movement of an attack --  to offer mitigation and risk reduction tactics. I-WARN aims to deliver actionable intelligence, offering early warning into threat behaviors, and mitigation responses.  This paper discusses the technical details of I-WARN, non-exhaustive  current solutions for threat intelligence sharing, and future work.","PeriodicalId":115235,"journal":{"name":"Electron.

Mechanisms such as fingerprinting are utilized to automatically extract information from ongoing network traffic and map this to a specific device or application, e.g., a browser. Active approaches directly interfere with the traffic and impose security risks or are simply infeasible. Therefore, passive approaches are employed, which only monitor traffic but require a well-designed feature set since less information is available. However, even these passive approaches impose privacy risks. Browser identification from encrypted traffic may lead to data leakage, e.g., the browser history of users. We propose a passive browser fingerprinting method based on explainable features and evaluate two privacy protection mechanisms, namely differentially private classifiers and differentially private data generation. With a differentially private Random Decision Forest, we achieve an accuracy of 0.877. If we train a non-private Random Forest on differentially private synthetic data, we reach an accuracy up to 0.887, showing a reasonable trade-off between utility and privacy.","PeriodicalId":115235,"journal":{"name":"Electron.

Especially in the context of mobile devices and with regard to usability, there is an increasing focus on methods where the user's behavior is used as authentication factor (e.g., touchscreen interactions or sensors). As this typically requires the processing of large amounts of sensitive data, issues related to privacy and scalability arise.

In order for agents to cooperate efficiently in such domains, they need to distribute tasks, share knowledge, resolve conflicts, incorporate unknown agents, assign roles among each other, assign and keep track of teams of agents, etc. The cooperation in such dynamic domains requires both a software platform that supports the interoperability of cyber-physical agents as well as a shared Knowledge Base that stores general semantic information about the entities of discourse as well as live status information. ALICA, which is an in-house Multi-Agent platform, addresses such domains and is well suited to tackle a lot of these problems. To further enhance its capabilities, an extension is planned in order to integrate the standardised context information interface NGSI-LD as well as the widely used FIWARE models and components for Smart Cities, which enables the management of static and dynamic context information in normal and crisis situations.","PeriodicalId":115235,"journal":{"name":"Electron.
