    Opportunities and challenges of blockchain technology for negotiation support systems
    (2025) Witt, Josepha; Schoop, Mareike; Knaus, Konstantin
    Blockchain Technology (BCT) is the backbone of the next generation of the internet and thus affects how electronic business (e-business) is conducted. While the usage of BCT for the initiation and transaction phases in e-business has been studied, the negotiation aspect has not been considered in a comprehensive manner. The current literature on the utilisation of BCT in electronic negotiations (e-negotiations) primarily focuses on autonomous agents and lacks research on the support of e-negotiations conducted by human negotiators using negotiation support systems (NSSs). This results in the issue that the consequences of a transition to Web3.0-based NSSs are unclear, while other areas of e-business already apply Web3.0 technologies. We address this lack of knowledge following a design-oriented approach in three steps exploring the opportunities and challenges of using BCT for e-negotiations via NSSs. Firstly, the well-established negotiation support system Negoisst is extended by BCT features resulting in the development of a Web3.0-based NSS called NegoisstBCT to demonstrate the technical feasibility of this approach. Secondly, the potential opportunities and challenges of a Blockchain-based NSS are analysed referring to its technical architecture. Thirdly, a generalised view of the application of Web3.0-based NSSs in different settings is taken, discussing future research on BCT in e-negotiations. The present research thus fosters the application of Blockchain-based NSSs in e-negotiations and of NSSs in BCT application areas.

    Practices and challenges of threat modelling in agile environments
    (2023) Theurich, Paul; Witt, Josepha; Richter, Sebastian
    Facing the increasing annual cybersecurity costs, threat modelling (TM) is a method to consider security as early as possible in the software development life cycle (SDLC). Thereby, TM helps to identify and address security-related design flaws in information systems. As the original TM approach is based on sequential development, it is not aligned with today’s predominantly agile environments. This results in several challenges. However, TM’s implementation in an agile development approach lacks the recommendations on how to tackle these challenges. Therefore, we assess the state-of-the-art of TM challenges and practices in agile environments by conducting a literature review covering 220 papers. Thereby, we identify nine categories of challenges and six categories of practices. We propose a valuable artefact for practitioners by mapping challenges and practices to the agile SDLC and by creating a matrix highlighting how the practices address the challenges of TM in an agile environment.
