Security & Networks

The Security and Networks Research Group (SNRG) efforts are concentrated in research and innovation within the larger field of Information Security with a specific focus on Computer Networks, Telecommunications and Communications Security.

Members of the group  are currently involved in a variety of projects, including a selection of visualisation techniques for security metrics, network traffic classification and monitoring, intrusion detection and hardware acceleration of these  and other network and security centric  tasks using commodity graphics cards. The group has been active since 2003 and is currently among the largest on campus.

The research group has a number of areas in which work is currently being done. These include:

•    Network Security analytics
•    Cyber Defense
•    Data Visualisation
•    Malware analysis
•    Digital Forensics
•    Hardware for supporting network processing

In collaboration with the department of Physics & Electronics, recent projects have fabricated specialist hardware for doing network traffic manipulation and analysis.

The core project of the group focuses around passive network intelligence , threat intelligence and mitigation, using data collected from the groups five /24 sized network telescopes, and a number of other direct and open source providers.

External collaboration exists with a number of commercial Industry partners, and within the CSIR, and larger defense  and tellecommunications sectors.

The majority of research is based on empirical data analysis, and experimental validation of software systems. Elements of Design Science are used within research relating to the application of information security within the Health Informatics space.
