Monetarisierungsstrategien unabhängiger Podcasts
No full textDie vorliegende Bachelorarbeit untersucht, inwiefern unterschiedliche Monetarisierungsstrategien den finanziellen und langfristigen Erfolg unabhängiger Podcasts beeinflussen. Vor dem Hintergrund eines wachsenden Podcast-Marktes und der bislang begrenzten wissenschaftlichen Auseinandersetzung mit unabhängigen Formaten zielt die Arbeit darauf ab, ein vertieftes Verständnis für die Zusammenhänge zwischen angewandten Strategien, Herausforderungen und Erfolgsfaktoren zu entwickeln.
Die empirische Untersuchung folgt einem qualitativen Forschungsdesign. Dazu wurden leitfadengestützte Expert:inneninterviews mit fünf unabhängigen Podcastenden durchgeführt und im Anschluss mittels qualitativer Inhaltsanalyse nach Mayring ausgewertet.
Die Ergebnisse verdeutlichen, dass Podcastende verschiedene Einnahmequellen wie Werbung, Sponsoring, direkte Zuhörenden-Finanzierung, Merchandise oder Live-Auftritte kombinieren. Der Erfolg wird dabei überwiegend subjektiv durch Sinnhaftigkeit, Inhaltsqualität und eine enge Bindung zur Community definiert, während finanzielle Aspekte vor allem der Projektsicherung dienen. Authentizität, ein konsistentes Konzept, Regelmäßigkeit und Interaktion mit der Community stellen zentrale Erfolgsfaktoren dar. Gleichzeitig bestehen Herausforderungen wie begrenzte Ressourcen, bürokratische Hürden und die ambivalente Rolle von Streaming-Plattformen. Zudem übersteigen anfängliche Investitionen häufig die erzielten Einnahmen.
Die Arbeit zeigt, dass für nachhaltigen Erfolg zunächst Produkt und Konzept im Vordergrund stehen sollten, während Monetarisierungsmodelle strategisch kombiniert und bewusst in den Entwicklungsprozess integriert werden. Eine kontinuierliche Qualitätssicherung, der Aufbau einer loyalen Community sowie eine sorgfältige Auswahl von Kooperationen tragen maßgeblich dazu bei, Unabhängigkeit und Integrität zu bewahren.This bachelor thesis investigates the extent to which different monetisation strategies influence the financial and long-term success of independent podcasts. In context of a growing podcast market and the limited scientific discussion of independent formats currently, the thesis aims to develop a deeper understanding of the connections between used strategies, challenges and success factors.
The empirical study follows a qualitative research design. To this aim, guided expert interviews were done with five independent podcasters and then evaluated using qualitative content analysis according to Mayring.
The results show that podcasters combine various sources of income such as advertising, sponsorship, direct listener financing, merchandise and live performances. Success is primarily defined subjectively by meaningfulness, content quality, and a close connection to the community, while financial aspects primarily serve to secure the project. Authenticity, a consistent concept, regularity and interaction with the community are key success factors. At the same time, there are challenges such as limited resources, bureaucratic challenges and the ambivalent role of streaming platforms. In addition, initial investments often exceed the income generated.
The work shows that for sustainable success, the product and concept should initially be the focus, while monetisation models should be strategically combined and consciously integrated into the development process. Continuous quality assurance, building a loyal community and carefully selecting collaborations contribute significantly to maintaining independence and integrity

Avatar Embodiment and the Proteus Effect
No full textAs the Internet gradually evolves into the metaverse, users’ interaction with places, people, and even themselves will become increasingly mediated by virtual self-representations, called avatars. Deeply tied to avatar use, the Proteus effect suggests that an avatar’s identity characteristics influence the way the users will behave. The Proteus effect represents one of the most interesting, impactful, and perhaps concerning ways that the avatars will play a role in future metaverse-mediated lives

Heterogeneous Real-Time & Secure Networks: TSN over Anything & TLS over Anything
No full textIn these days, industrial communication comes with manifold requirements: (1) they need to be real-time, i.e. following the vendor independent Time-Sensitive Networking (TSN) approach, (2) they must be secure, i.e. following the state-of-the-art technologies, like Transport Layer Security (TLS) protocols, and (3) the different wired and wireless network types need to be much more integrated and managed in a unified way. A lot of research is currently executed on these three directions. However, the real challenge begins, if all these objectives have to be followed in a combined approach.This short paper gives an overview on the current state of the art with regard to end-to-end solutions for heterogeneous real-time and secure networks. It presents some solutions from the author’s team, most notably the approaches of TSN over Anything and TLS over Anything, and discusses open research questions.It is a summary of an invited keynote presentation at 2025 IEEE International Conference on Computer, Information, and Telecommunication Systems (CITS 2025) in Colmar, France
Realistic Modelling and Optimization of DTLS Handshakes in Constrained LPWAN Environments
No full textWith the growing popularity of Low Power Wide Area Networks (LPWANs) in large-scale Internet of Things (IoT) deployments, ensuring secure yet efficient communication presents a significant challenge. Datagram Transport Layer Security (DTLS) is designed to provide end-to-end security. However, there is a substantial communication overhead associated with DTLS that makes it impractical for resource-constrained environments, such as Low Power Wide Area Networks (LPWANs). This paper presents a simulation-based evaluation of the DTLS handshake performance over two major LPWAN technologies— LoRaWAN and mioty —incorporating realistic network conditions, including packet loss, duty cycle limitations, and message fragmentation. Unlike prior studies based on idealized airtime models, our approach provides actionable insights into real-world performance. We also utilize the Static Context Header Compression(SCHC) mechanism to reduce protocol overhead, achieving around 60% reductions in both handshake duration and message size. Furthermore, we compare the performance of DTLS handshake variants, analyzing trade-offs between certificate-based and Pre-Shared Key (PSK) authentication in constrained environments. Our research is highly relevant for the development of secure and efficient IoT communication protocols by contributing to the ongoing optimization efforts
A YANG Model-Based Approach for Configuration and Management of 5G-TSN Bridges
No full textTime-Sensitive Networking (TSN) and especially its integration into private 5 G networks is becoming increasingly important for industrial applications. By introducing 5G-TSN bridges, the combination of the strengths from both technologies would allow high-performance, reliable deterministic wireless networks, which are flexible in the sense of the network topology and its dynamic behavior. In addition, converged networks become real, avoiding the need of separation between Operation Technology and Information Technology. The basic mechanisms of TSN, such as time synchronization or scheduling inside a private 5 G network and through a 5 G TSN bridge, have already been specified, investigated and proven in different research and prototype works. However, to make use of these features in a fully operational environment, such a bridge must be properly configured. Starting from declaring, enabling and configuring available ports, other processes, such as port and device discovery, need to be covered to allow a seamless integration of a 5G-TSN bridge into the overall network. At least from the design and implementation side, the internal configuration of such a 5 G -TSN bridge is not yet fully available. This work proposes a novel standard-compatible YANG (Yet Another Modeling Language) model-based approach and architecture to model and access the configuration and maintenance of a 5G-TSN bridge within a TSN network. We break down the single processes and structures at the involved entities and present a reference design for the practical implementation of such a configuration and management interface, while corresponding to the YANG model-based configuration methods from TSN networks
Enhancing Command & Control Capabilities: Integrating Cobalt Strike's Plugin System into a Mythic-based Beacon Developed at cirosec
Get PDFCommand & Control (C2) frameworks are a popular tool for bad actors to attack and infiltrate infrastructures and systems. They allow long-lasting inroads to be made into the infrastructure, through which attackers can interact with it through covert channels. These frameworks thus also play a crucial role in cybersecurity, enabling red teams and penetration testers to simulate those real-world adversary tactics. Cobalt Strike, a widely used proprietary C2 framework, offers an extensible plugin system through Beacon Object Files (BOFs). Mythic, an open-source alternative, provides a modular architecture but lacks native BOF compatibility.
This thesis explores the feasibility of integrating Cobalt Strike’s BOF capabilities into a Mythic-based beacon developed at cirosec. The research begins by analyzing the structural and functional differences between Cobalt Strike and Mythic, focusing on their plugin systems and execution environments. It then examines the technical details of BOF execution, including Dynamic Function Resolution (DFR), memory management, and interactions with the beacon Application Programming Interface (API).
The core contributions of this work are the design and implementation of a generic BOF runtime and the implementation of it within the Mythic-based beacon “ciroStrike” developed by cirosec. By adapting BOF execution mechanisms and ensuring compatibility with Mythic’s architecture, this integration enhances the beacon’s flexibility while maintaining its compact and evasive nature. Furthermore, an analysis of publicly available BOF implementations evaluates their applicability to this approach.
The results demonstrate that BOFs can be successfully executed within Mythic with minimal modifications, bridging the gap between proprietary and open-source C2 frameworks. This research contributes to the evolution of offensive security tooling by expanding the interoperability of red team frameworks and improving the adaptability of C2 beacons
Enhancing Vendor Risk Management: Best Practices for Security Oversight
No full textIn an era of accelerating digital transformation and increasing regulatory scrutiny, third-party risk management (TPRM) has become a strategic imperative for financial institutions. This thesis examines the TPRM framework of Deutsche Börse Group (DBG), a critical financial market infrastructure provider, with the aim of evaluating its current maturity, identifying internal control gaps, and proposing targeted improvements aligned with international regulatory expectations. The research adopts a qualitative case study methodology, leveraging internal documents,stakeholder feedback, and benchmarking against established standards such as DORA, the ECB SSM guidelines, ISO 27001, and COBIT. A detailed internal insight analysis reveals gaps in areas such as automation, fourth-party risk visibility, performance monitoring, and escalation protocols. These are further mapped against best practices to quantify maturity levels and assess risk exposure. Based on the findings, a set of strategic recommendations is proposed across five dimensions: governance, process, technology, compliance, and culture. These are structured into a phased implementation roadmap to support DBG’s efforts in achieving operational resilience and regulatory alignment. The thesis contributes both to academic understanding of TPRM in highly regulated environments and to practical enhancements for financial institutions operating under European supervision
