Cyber ranges enable security experts to emulate computer networks where they can perform cyber security exercises and experiments. Although their architecture may differ, the following four types of services are usually provided: (a) Resource management, i.e. the allocation of network infrastructure with requested topology and running applications....

This paper introduces the KYPO -- a cloud-based virtual environment faithfully simulating real networks and enabling users to study cyber attacks as well as to train users in isolated and controlled environment. Particularly, the paper focuses on the user environment and visualizations, providing views and interactions improving the understanding o...

In this paper we present a cloud-based research testbed designed to aid network security managers. The testbed enables operators to emulate various network topologies, services, and to analyze attacks threatening these systems. A possibility to test results of network management measures is desired, since testing these measures in a production envi...

Enterprise Resource Planning (ERP) systems had grown into complex applications integrating various processes and large amounts of data in detail. Such complexity negatively impacts usability owing to providing single static user interface that should meet users with diverse roles, tasks and requirements. In this paper we introduce a concept of adap...

This paper introduces novel approach to logging user activity in software applications that provide accurate high-level information about issued commands, commands parameters and user interaction styles without a need for inferring user activity from logged user interfaces events as it is required on most loggers these days. We also demonstrate the...

We introduce novel fine-grained adaptive user interface for the OpenOffice.org Writer word processor. It provides a panel container with personalized user interface to an individual user. The personalization is provided on frequently or recently used user commands, user’s preferred interaction styles and frequently used parameters to user commands....

We introduce a research framework which enables to use the OpenOffice.org as a platform for HCI research, particularly for performing user studies or prototyping and evaluating intelligent user interfaces. We make two contributions: (1) we introduce an innovative hybrid logging technique which provides high-level, rich and accurate information abou...
