Multi-Cloud Information Security Policy Development

Organizations’ ever lasting desire to utilize new trending technologies for optimizing their businesses have been increasing by the years. Cloud computing has been around for a while, and for many became a vital part of their day-to-day operations. The concept of multi-cloud has allowed organizations to take advantage of every cloud vendor’s best services, hinder vendor lock-in, resulting in cost optimization, and resulting in more available services. With every new technology, there are new vulnerabilities ready to be exploited at any time. As there is little prior research regarding this field, threat actors can exploit an organization’s ignorance on important challenges such as interoperability issues, implementing multiple vendors resulting in losing track of their services, and the lack of expertise in this newly founded field. To alleviate such issues, one approach could be to develop information security policies, hence our research question for the thesis: How to develop information security policies in a multi-cloud environment with considerations of the unique challenges it offers? To uncover the research question, we have conducted a systematic literature review followed up by a qualitative research approach. This has resulted in six semi-structured interviews from respondents with a variety of experience within the multi-cloud realm. The most prominent findings from this exploratory study has been the focus of thoroughly planning the need of a multi-cloud and information security policies, as well as applying a top-down approach for the policy development phase. This gives a more holistic view over the process, and additionally having the right competence is important. An interesting finding was that multi-cloud on paper should prevent the vendor lock-in issue, but in reality may provoke the matter. Using the tools and services provided by the cloud service providers may enhance the development of information security policies, but proves to be difficult in multi-cloud as the problem of interoperability hinders this. Lastly, reviewing policies becomes more timeconsuming and resource heavy in a multi-cloud because of the frequent updates and changes in technology, which has to be monitored. This research presents a conceptual framework, which by no means is a one-size-fits-all solution, but raises discussion for future work in this field

Aspects of Unstructured Grids and Finite-Volume Solvers for the Euler and Navier-Stokes Equations

One of the major achievements in engineering science has been the development of computer algorithms for solving nonlinear differential equations such as the Navier-Stokes equations. In the past, limited computer resources have motivated the development of efficient numerical schemes in computational fluid dynamics (CFD) utilizing structured meshes. The use of structured meshes greatly simplifies the implementation of CFD algorithms on conventional computers. Unstructured grids on the other hand offer an alternative to modeling complex geometries. Unstructured meshes have irregular connectivity and usually contain combinations of triangles, quadrilaterals, tetrahedra, and hexahedra. The generation and use of unstructured grids poses new challenges in CFD. The purpose of this note is to present recent developments in the unstructured grid generation and flow solution technology

ERP implementation methodologies and frameworks: a literature review

Enterprise Resource Planning (ERP) implementation is a complex and vibrant process, one that involves a combination of technological and organizational interactions. Often an ERP implementation project is the single largest IT project that an organization has ever launched and requires a mutual fit of system and organization. Also the concept of an ERP implementation supporting business processes across many different departments is not a generic, rigid and uniform concept and depends on variety of factors. As a result, the issues addressing the ERP implementation process have been one of the major concerns in industry. Therefore ERP implementation receives attention from practitioners and scholars and both, business as well as academic literature is abundant and not always very conclusive or coherent. However, research on ERP systems so far has been mainly focused on diffusion, use and impact issues. Less attention has been given to the methods used during the configuration and the implementation of ERP systems, even though they are commonly used in practice, they still remain largely unexplored and undocumented in Information Systems research. So, the academic relevance of this research is the contribution to the existing body of scientific knowledge. An annotated brief literature review is done in order to evaluate the current state of the existing academic literature. The purpose is to present a systematic overview of relevant ERP implementation methodologies and frameworks as a desire for achieving a better taxonomy of ERP implementation methodologies. This paper is useful to researchers who are interested in ERP implementation methodologies and frameworks. Results will serve as an input for a classification of the existing ERP implementation methodologies and frameworks. Also, this paper aims also at the professional ERP community involved in the process of ERP implementation by promoting a better understanding of ERP implementation methodologies and frameworks, its variety and history
