    Computational Economics als wirtschaftsinformatischer Beitrag zu einer interdisziplinären Netzwerktheorie
    (Wirtschaftsinformatik: Vol. 45, No. 5, 2003) Weitzel, Tim; König, Wolfgang
    Standards provide for compatibility and can therefore constitute networks. A possible contribution of the discipline of IS is transcending traditional economic network analysis by incorporating an interdisciplinary view on networks with economic utility maximization and an agent-based computational economics (ACE) approach. In doing so, the complex dynamics in networks occasioned by the existence of network effects and socially situated agents with bounded rationality can be modelled using computational laboratories. This provides an important step towards evaluating and develop alternative socioeconomic structures with regard to their effects on individual behavior and social welfare.

    On a network forensics model for information security
    (Information systems technology and its applications, 3rd international conference ISTA'2004, 2004) Wei, Rei
    The employment of a patchwork of nonintegrated security products can only provide incomplete coverage, which cannot give the total panorama of the network misuse behavior. Network forensics is a new approach for the incident investigation and emergence response, which also enhance the network security from a different point of view. However, the current network forensics system is confused with the network monitor system or sniffer system. It always is misconstrued to an only network traffic capture system. In this paper, we for the first time discuss the concept model of network forensics system, which can give guidance for the implementation of network forensics system and the formalization of the network forensics procedure, which is a principle element of the recognition between the law enforcement participation. Particularly, some novel approaches for network forensics system are discussed for the first time, such as network forensics server, network forensics protocol and standardization, and so on.

    A Testing Framework Architecture for Automotive Intrusion Detection Systems
    (Automotive - Safety & Security 2017 - Sicherheit und Zuverlässigkeit für automobile Informationstechnik, 2017) Corbett, Christopher; Basic, Tobias; Lukaseder, Thomas; Kargl, Frank
    Vehicles are the target of a rising number of hacking attacks. The integration of in-vehicle intrusion detection systems is a common approach to increase the overall system security. However, testing and evaluating these systems is difficult due to the lack of tools to generate realistic benign and malicious workloads as well as sharing these workloads with other researchers. Currently, test- ing tools are predominantly intended for Network Intrusion Detection System (NIDS) in company or industrial networks where their usefulness became apparent. Yet, in the automotive domain, development of testing tools is still in the early stages. Existing non-commercial automotive tools only focus on one specific bus technology each. However, in-vehicle communication exceeds bus technology boundaries and a testing tool must cover multiple technologies. We propose a framework architecture concept for in-vehicle NIDS testing and evaluation to enable the creation of realistic network traffic and attacks in consideration of automotive specific challenges. Our concept provides the opportunity to share data without additional anonymization effort therefore improving cooperation and reproducibility of testing results.
