摘要:
The intent of this research is to develop and assess the application of 3D data visualisation to the field of computer security. The growth of available data relating to computer networks necessitates a more efficient and effective way of presenting information to analysts in support of decision making and situational awareness. Advances in computer hardware and display software have made more complex and interactive presentation of data in 3D *** many attempts at creation of data-rich 3D displays have been made in the field of computer security, they have not become the tool of choice in the industry. There is also a limited amount of published research in the assessment of these tools in comparison to 2D graphical and tabular approaches to displaying the same *** research was conducted through creation of a novel abstraction framework for visualisation of computer network data, the Visual Interactive Network Analysis Framework (VINAF). This framework was implemented in software and the software prototype was assessed using both a procedural approach applied to a published forensics challenge and also through a human participant based *** key contributions to the fields of computer security and data visualisation made by this research include the creation of a novel abstraction framework for computer network traffic which features several new visualisation approaches. An implementation of this software was developed for the specific cybersecurity related task of computer network traffic analysis and published under an open source license to the cybersecurity community. The research contributes a novel approach to human-based experimentation developed during the COVID-19 pandemic and also implemented a novel procedure-based testing approach to the assessment of the prototype data visualisation *** of the research showed, through procedural experimentation, that the abstraction framework is effective for network forensics tasks an
