The evaluation of a conceptual model, which is an outcome of a qualitative research, is an arduous task due to the lack of a rigorous basis for evaluation. Overcoming this challenge, the paper at hand presents a detailed example of a multifaceted evaluation of a Reference Model of Information Assurance & Security (RMIAS), which summarises the knowledge acquired by the Information Assurance & Se...

As society increasingly relies on digitally stored and accessed information, applications have increasingly higher requirements on supporting the availability, integrity, and confidentiality of this information. However, as the quantity and severity of cyber vulnerabilities and attacks continuously increase, traditional information security technologies are increasingly limited in satisfying th...

−An intersection of two worlds, emerging nanotechnologies and network/communication theory, is poised to change the nature of information assurance. New communication paradigms will be derived from the transition from microto nano-scale devices. The related degrees of freedom and constraints associated with these new technologies will change our notions about efficient networks, system design a...

The fluid, dispersed market of e-commerce makes it hard to judge the reliability of participants. While early Internet trust practices merge old practices—acknowledgments, customer surveys, audits—into Web technology, a need exists for better approaches to assurance. Ideally, these trust mechanisms should be inexpensive, scalable, and private. The proposed three-level hierarchy of ever more pow...

We address the problem of constructing an assurance case and propose an approach to extract information from an issue tracking system that can be used to construct an assurance case. This approach takes advantage of information searching and data mining techniques to identify relevant information, which can also be used as materials for constructing an assurance case. This paper gives an overvi...
