    Hacking Trucks - Cybersecurity Risks and Effective Cybersecurity Protection for Heavy Duty Vehicles
    (Automotive - Safety & Security 2017 - Sicherheit und Zuverlässigkeit für automobile Informationstechnik, 2017) Wolf, Marko; Lambert, Robert
    Similar to passenger cars, heavy-duty vehicles, such as commercial trucks and buses, are becoming increasingly software-driven, interconnected and semi-automated, and hence are also becoming increasingly susceptible to cybersecurity attacks. This article will identify and evaluate these cybersecurity threats and risks affecting the monetary business operation, reliability, and safety of heavy-duty vehicles, comparing them with similar cybersecurity risks for typical passenger vehicles. Based on this overall cybersecurity threat and risk analysis, the article will then present and explain our holistic and multi-layer protection approach to reduce such cybersecurity risks for heavy-duty vehicles.

    On Textual Analysis and Machine Learning for Cyberstalking Detection
    (Datenbank-Spektrum: Vol. 16, No. 2, 2016) Frommholz, Ingo; al-Khateeb, Haider M.; Potthast, Martin; Ghasem, Zinnar; Shukla, Mitul; Short, Emma
    Cyber security has become a major concern for users and businesses alike. Cyberstalking and harassment have been identified as a growing anti-social problem. Besides detecting cyberstalking and harassment, there is the need to gather digital evidence, often by the victim. To this end, we provide an overview of and discuss relevant technological means, in particular coming from text analytics as well as machine learning, that are capable to address the above challenges. We present a framework for the detection of text-based cyberstalking and the role and challenges of some core techniques such as author identification, text classification and personalisation. We then discuss PAN, a network and evaluation initiative that focusses on digital text forensics, in particular author identification.

    Sol: An Agent-Based Framework for Cyber Situation Awareness
    (KI - Künstliche Intelligenz: Vol. 26, No. 2, 2012) Bradshaw, Jeffrey M.; Carvalho, Marco; Bunch, Larry; Eskridge, Tom; Feltovich, Paul J.; Johnson, Matt; Kidwell, Dan
    In this article, we describe how we augment human perception and cognition through Sol, an agent-based framework for distributed sensemaking. We describe how our visualization approach, based on IHMC’s OZ flight display, has been leveraged and extended in our development of the Flow Capacitor, an analyst display for maintaining cyber situation awareness, and in the Parallel Coordinates 3D Observatory (PC3O or Observatory), a generalization of the Flow Capacitor that provides capabilities for developing and exploring lines of inquiry. We then introduce the primary implementation frameworks that provide the core capabilities of Sol: the Luna Software Agent Framework, the VIA Cross-Layer Communications Substrate, and the KAoS Policy Services Framework. We show how policy-governed agents can perform much of the tedious high-tempo tasks of analysts and facilitate collaboration. Much of the power of Sol lies in the concept of coactive emergence, whereby a comprehension of complex situations is achieved through the collaboration of analysts and agents working together in tandem. Not only can the approach embodied in Sol lead to a qualitative improvement in cyber situation awareness, but its approach is equally relevant to applications of distributed sensemaking for other kinds of complex high-tempo tasks.
