  • A visual modelling technique for controlling graph transformations 
    Gruner, Stefan; Kurt, Murat; Taentzer, Gabriele (Carleton Scientific, 2000)
    Sophisticated control concepts are necessary to make the application of graph grammars feasible for practical graph grammar engineering and specification tasks. For this purpose we introduce hybrid control graphs based on ...
  • A tool for interactive visualization of distributed algorithms 
    Gruner, Stefan; Mosbah, Mohamed; Bauderon, Michel (2001)
    We present a tool for the visualization of distributed computations. Special attention is payed to certain distributed algorithms which have been coded as rewriting systems. In order to study the behaviour of algorithms ...
  • An access control framework for web services 
    Coetzee, Marijke; Eloff, Jan H.P. (Emerald, 2005)
    Purpose – To define a framework for access control for virtual applications, enabled through web services technologies. The framework supports the loosely coupled manner in which web services are shared between partners. ...
  • Uncovering identities: a study into VPN tunnel fingerprinting 
    Izadinia, Vafa Dario; Kourie, Derrick G.; Eloff, Jan H.P. (Elsevier, 2006)
    Operating System fingerprinting is a reconnaissance method which can be used by attackers or forensic investigators. It identifies a system's identity by observing its responses to targeted probes, or by listening on a ...
  • The use of self-organising maps for anomalous behaviour detection in a digital investigation 
    Fei, B.K.L. (Bennie Kar Leung); Eloff, Jan H.P.; Olivier, Martin S.; Venter, H.S. (Hein) (Elsevier, 2006-10)
    The dramatic increase in crime relating to the Internet and computers has caused a growing need for digital forensics. Digital forensic tools have been developed to assist investigators in conducting a proper investigation ...
  • Web services access control architecture incorporating trust 
    Coetzee, Marijke; Eloff, Jan H.P. (Emerald, 2007)
    PURPOSE – This paper seeks to investigate how the concept of a trust level is used in the access control policy of a web services provider in conjunction with the attributes of users. DESIGN/METHODOLOGY/APPROACH – A ...
  • Information security culture - validation of an assessment instrument 
    Da Veiga, A.; Martins, Nico; Eloff, Jan H.P. (College of Economic and Management Sciences, University of South Africa, 2007-04)
    Organisations need to ensure that the interaction among people, as well as between people and information technology (IT) systems, contributes to the protection of information assets. Organisations therefore need to assess ...
  • How big is your IT department? 
    Gruner, Stefan (Computer Society of South Africa, 2007-06)
    If you follow the recent IT-related discussions in South Africa with open ears, you will certainly have heard voices complaining about a shortage of skilled staff in the IT industry and a too low output of MSc-Graduates ...
  • What is an address in South Africa? 
    Coetzee, Serena Martha; Cooper, Antony Kyle; Adam, John B. (AOSIS Open Journals, 2007-11)
    Addresses come in many forms as they have a variety of uses. In our paper we illustrate the need for standardized addresses in South Africa by describing scenarios where standardized addresses are required, or where ...
  • Informatics for historians : tools for medieval document XML Markup, and their impact on the History-Sciences 
    Burkard, Benjamin; Vogeler, Georg; Gruner, Stefan (Graz University of Technology, 2008)
    This article is a revised and extended version of [VBG, 07]. We conjecture that the digitalization of historical text documents as a basis of data mining and information retrieval for the purpose of progress in the history ...
  • Team trails, trials and tribulations - rigorously reckoning with requirements 
    Pieterse, Vreda; Du Toit, Cecilia Magdalena (Unisa Press, 2008)
    A major challenge to the efficacy of student team learning projects occurs when some members of a group are unable to contribute effectively to the collaborative endeavour due to their academic deficits. A graded benchmark ...
  • From use cases to test cases via meta model-based reasoning 
    Gruner, Stefan (Springer-Verlag, 2008)
    In "use cases considered harmful", Simons has analyzed the logical weaknesses of the UML use case notation and has recommended to “fix the faulty notion of dependency” (Simons: Use cases considered harmful. 29th Conference ...
  • Letter to the editor : 40 years after Garmisch
