Collapse Button Quick Abstract
The increasing significance of information technology (IT) security in modern life and the rising number of cybersecurity regulations and legislation are creating a high demand for IT security experts, which is currently unmet, resulting in numerous vacancies. To address this shortage of skilled professionals, it is crucial to cultivate early interest among students. In the present study, the game-based system CampusQuest is introduced as a tool to engage students in cybersecurity from the outset and to stimulate their ambition in this field. The system is based on the concept of solving challenges, similar to the format of so-called Capture the Flag competitions. However, the challenges have been adapted to align with the specific context of a university campus, combining various additional elements. CampusQuest incorporates physical elements into the challenges, which are distributed permanently across the campus and motivate individuals to participate. Additionally, the system has been enhanced with a mechanism to prevent the dissemination of solutions. The system has been implemented in a prototype form and currently comprises eleven challenges of varying degrees of difficulty, which is designed to facilitate the introduction of the subject to first-year students.

Collapse Button Quick Abstract
In today’s world, there are more and more IT systems that are interconnected to provide services to a wide variety of business classes. Since their services are usually inevitably linked to financial and political interests, the number of attacks aimed at disrupting or profiting from these and the associated systems in various ways is constantly increasing. In this paper we design and implement a framework for the comprehensive auditing of IT systems in system architectures of different enterprise classes. For our solution, we evaluate formal requirements regarding audit trails, provide concepts for the pseudonymisation of audit data, develop software components for E2E audit trails and finally present a secure system architecture based on Kubernetes and Istio in conjunction with the storage components ArangoDB and HashiCorp Vault to achieve an efficient framework for creating E2E audit trails.

Collapse Button Quick Abstract
The need for compliance and the growing number of IT security threats force many companies to improve their level of IT security. At the same time, new legal regulations and the trend to interconnect IT with automation environments (operational technology, OT) lead to the situation that IT security and OT security need to be approached at the same time. However, OT differs from IT in several aspects and many well-established IT security procedures cannot simply be copied to OT networks. As in IT the first step to establish an acceptable security level for OT is to perform a proper risk assessment. Available tools that support OT asset management are either expensive or they do not provide the functionality needed. In the context of this paper a new open-source approach to OT asset management is presented. The tool that was developed to collect OT assets considers the specific characteristics of OT devices, the sensitivity of production environments, and the typically rudimentary starting situation of many real-world machine operators while being free of charge at the same time.

Collapse Button Quick Abstract
The second half of the last century was characterised by a shift from manufacturing to services, particularly in mature economies. This transformation has accelerated in the past decade, due to rapid progress in information technology. Excellence in the so-called STEM subjects (science, technology, engineering and mathematics) is crucial if countries are to remain competitive. Mathematics as a universally applicable method is of special significance, as is IT, which impacts on virtually all industries and can dramatically change economies. Literacy in mathematics and computers, therefore, is more important than ever for individuals, companies and countries. We propose a framework based on R to support the training of students in these crucial areas. We discuss its features, including platform neutrality, costs and specialization flexibility in our paper.

Collapse Button Quick Abstract
The number of people who are solo-self-employed or experience very flexible, individualized working conditions has grown over the last years. As a consequence, these persons need to design their own working conditions in the sense of ‘job crafting’. We are developing an online coaching application for this target group to convey job design skills, increase well-being, and reduce stress. To enhance user motivation gamification elements are used in the online coach. In this paper we report on the evaluation of a prototype of the coaching application with different gamification elements by means of a user test with the target group. The results show that gamification has only a small effect in short-term use, but seems promising in the long term.

Collapse Button Quick Abstract
Research on informal Social Networks such as Facebook has so far mainly focused on participants’ private exchange, addressing topics like self-disclosure, self-presentation, privacy issues and so on. However, informal Social Networks, despite their more private nature, might also be used for work-related exchange and private support for workplace challenges and problems. In this paper we investigate to what extent informal Social Networks are used for work-related exchange and whether this is related to forms of social support the participants experience. To that end an online survey was conducted among users of Facebook. Results show that while work-related Facebook use is generally low, there is some potential to use Social Networks as a vehicle to build a strong support network for seeking of valuable information and advice to cope with possible work-related challenges, especially as participants showed a high willingness to extend help and support to other users.

Collapse Button Quick Abstract
Computer modelling of 2D drawings is becoming increasingly popular in modern design as can be witnessed in the shift of modern computer modelling applications from software requiring specialised training to ones targeted for the general consumer market. Despite this, traditional sketching is still prevalent in design, particularly so in the early design stages. Thus, research trends in computer-aided modelling focus on the the development of sketch based interfaces that are as natural as possible. In this paper, we present a hybrid sketch based interface which allows the user to make draw sketches using offline as well as online sketching modalities, displaying the 3D models in an immersive setup, thus linking the object interaction possible through immersive modelling to the flexibility allowed by paper-based sketching. The interface was evaluated in a user study which shows that such a hybrid system can be considered as having pragmatic and hedonic value.
