About Us

The DigiForS research group undertakes research in Digital Forensic Science. DigiForS’s main objective is to find innovative security solutions for state-of-the-art technologies. This includes finding solutions that will help to make emerging technologies safe for use, using security technologies to enable new applications, find solutions that will better protect existing technology, as well as extracting forensically relevant information. Emerging problem areas receiving attention include: digital forensics, distributed trust and security issues in pervasive computing. More established problem areas in which work is ongoing include: privacy, vulnerability scanning, intrusion detection, database and workflow security, as well as a host of related areas. As well as collaborating very closely with industry, the DigiForS research team also collaborates with researchers in various countries such as UK, Germany, Switzerland, USA, Kenya, Swaziland, Namibia and Malaysia.

Research Focus

Our research activities include these focus areas:

  • Digital forensic Science
    The science of digital investigation. This include the science of the reliability of digital evidence acquisition and preservation, potential digital evidence identification, methodologies for effective analysis and presentation of digital evidence. The core of this research area is the attainment of reliable digital artefacts/evidence acquisition, preservation, analysis and presentation processes which can stand legal scrutiny and admissibility. This thus implies the development of policy, framework, model, metamodel, processes and procedure.
  • Digital policing and Forensics
    Digital policing and Forensics for developing nations
  • IoT device attribution
    The identification of IoT device in a smart city, using radio frequency identifiers
  • Digital Forensic Readiness in Online Examinations
    Application of various digital forensic readiness techniques to counter online examination fraud.
  • Internet of Things (IoT) Security
    Securing the Internet of things, IoT threats Mitigation and detection, Anomaly detection in IoT
  • Intelligent digital forensic readiness in the public cloud
    Intelligent digital forensic readiness in the public cloud
  • Digital forensic semantics readiness
    Digital forensic semantics readiness
  • Cybercrime semantic triggers
    Cybercrime semantic triggers
  • Ransomware Forensics
    Ransomware Forensics involves the process of finding potential digital evidence during a ransomware attack. This information includes but not limited too, the command and control server, encryption algorithms, the origin of the malware executable, the process of ransomware encryption and the process of demanding a ransom. Ransomware is an ongoing global threat where attackers are constantly finding innovative methods to trick and bypass detection methods.
