  • Feature selection using Benford’s law to support detection of malicious social media bots 
    Mbona, Innocent; Eloff, Jan H.P. (Elsevier, 2022-01)
    The increased amount of high-dimensional imbalanced data in online social networks challenges existing feature selection methods. Although feature selection methods such as principal component analysis (PCA) are effective ...
  • A fraud management system architecture for next-generation networks 
    Bihina Bella, M.A. (Madeleine Adrienne); Eloff, Jan H.P.; Olivier, Martin S. (Elsevier, 2009)
    This paper proposes an original architecture for a fraud management system (FMS) for convergent. Nextgeneration networks (NGNs), which are based on the Internet protocol (IP). The architecture has the potential to satisfy ...
  • Identity deception detection : requirements and a model 
    Van der Walt, Estee; Eloff, Jan H.P. (Emerald, 2019-09)
    PURPOSE : This paper aims to describe requirements for a model that can assist in identity deception detection (IDD) on social media platforms (SMPs). The model that was discovered demonstrates the usefulness of the ...
  • Information security : the moving target 
    Dlamini, Moses Thandokuhle; Eloff, Jan H.P.; Eloff, M.M. (Elsevier, 2009)

  • Integrated digital forensic process model 
    Kohn, Michael Donovan; Eloff, M.M.; Eloff, Jan H.P. (Elsevier, 2013-10)
    Digital forensics is an established research and application field. Various process models exist describing the steps and processes to follow during digital forensic investigations. During such investigations, it is not ...
  • A near-miss management system architecture for the forensic investigation of software failures 
    Bella, M.A. Bihina; Eloff, Jan H.P. (Elsevier, 2016-02)
    Digital forensics has been proposed as a methodology for doing root-cause analysis of major software failures for quite a while. Despite this, similar software failures still occur repeatedly. A reason for this is the ...
