The development of a national critical information infrastructure protection (CIIP) structure is essential to safeguard critical systems from cyber attacks and other threats. As developing nations leverage Internet technologies, it is imperative that they develop their own national CIIP structures to ensure reliable operations, incident response and resilience in the face of attacks. This paper...

We investigate the basic fold operations, often referred to as Huzita’s axioms, which represent the standard seven operations used commonly in computational origami. We reformulate the operations by giving them precise conditions that eliminate the degenerate and incident cases. We prove that the reformulated ones yield a finite number of fold lines. Furthermore, we show how the incident cases ...

Information Technology Infrastructure Library, ITIL framework, is a set of comprehensive publications providing descriptive guidance on the management of IT processes, functions, roles and responsibilities related to Information Technology Service Management. However, and in spite of its repercussion and popularity, the ITIL framework does not suggest an implementation order for their processes...

This review paper assesses the existing body of knowledge associated with digital forensic investigation process models. To this end, eleven of the existing models are critically reviewed and evaluated against an assessment criteria, namely the Daubert Test, to determine which models have taken the most scientific approach. This review and assessment reveal that the authors of these models have...

Service process orchestration using workflow technologies have led to significant improvements in generating predicable outcomes by automating tedious manual tasks but suffer from challenges related to the flexibility required in work especially when humans are involved. Recently emerging trends in enterprises to explore social computing concepts have realized value in more agile work process o...

Dynamics of IT support organizations can be quite complex to analyze. We introduce a prototype visualization tool that exploits similarities of support organizations with social networks. Our tool borrows techniques from social network visualization and analysis to help IT manager better understand dynamics of their organization in the incident management process.

Incident management systems have the potential to improve security dramatically but often experience problems stemming from organizational, interpersonal and social constraints that limit their effectiveness. These limits may cause underreporting of incidents, leading to erroneous perceptions of the actual safety and security situation of the organization. The true security situation may be bet...

IT security preparedness exercises allow for practical collaborative training, which in turn leads to improved response capabilities to information security incidents for an organization. However, such exercises are not commonly performed in the electric power industry. We have observed a tabletop exercise as performed by three organizations with the aim of understanding challenges of performin...
