Abstract:

Cybersecurity is currently an important and relevant issue, as more and more industries are taking advantage of the accessibility of storing information online. To create a secure system one must know the potential risks and attacks on that system, making risk analysis a very potent tool. In this study, we performed such an analysis using the risk analysis method OCTAVE Allegro on a company providing a cloud-based service to find out what risks a cloud service provider might be exposed to, and the usefulness of said risk analysis method in this circumstance. We found that OCTAVE Allegro is sui

Abstract:

The thesis investigates, in a qualitative way, the vectors that contribute to cloud computing risks in the areas of security, business, and compliance. The focus of this research is on the identification of risk vectors that affect cloud computing and the creation of a framework that can help IT managers in their cloud adoption process. Economic pressures on businesses are creating a demand for an alternative delivery of the model that can provide flexible payments, dramatic cuts in capital investment, and reductions in operational cost. Cloud computing is positioned to take advantage of these

These services range from complete DNS management to singular services such as E-mail or a payroll application.

Abstract:

In 2011 one-third of South African organisations did not intend to adopt cloud computing services because IT decision-maker lacked understanding of the related concepts and benefits (Goldstuck, 2011). This research develops a media-oriented model to examine the adoption of these services in South Africa. The model uses the technology acceptance model (TAM) and innovation diffusion theory (IDT) to develop variables that are considered determinants of adoption including trialability, complexity of understanding, perceived risk, perceived ease of use and perceived usefulness.An electronic survey

Abstract:

According to research, the risks of adopting new technology and the technological and organizational factors that influence adopting it are not clear. Thus, many financial institutions have hesitated to adopt cloud-computing. The purpose of this quantitative, cross-sectional study was to evaluate the cyber-risk implications of cloud-computing adoption in the U.S. financial services sector. The study examined 6 technological and organizational factors: organization size, relative advantage, compliance, security, compatibility, and complexity within the context of cyber-risk.

Abstract:

A malicious actor often relies on security vulnerabilities of IT systems to launch a cyber attack. Most cloud services are supported by an orchestration of large and complex systems which are prone to vulnerabilities, making threat assessment very challenging. In this research, I developed formal and practical ontology-based techniques that enable automated evaluation of a cloud system's security threats. I use an architecture for threat assessment of cloud systems that leverages a dynamically generated ontology knowledge base. I created an ontology model and represented the components of a cl

Abstract:

With the advancement of cloud computing, enterprises are moving their IT infrastructure to clouds. However, in adopting cloud services, Quality of Service (QoS) concerns need to be addressed for SLA management. In this thesis, an SLA management framework from a consumer’s point of view is proposed that first selects a trustworthy service provider who is capable of providing the requested service; and then monitors the performance of service delivery to ensure the quality of service.

Abstract:

This thesis gives an example of how decision analytic methods can be applied to choices in the adoption of cloud computing. The lifecycle of IT systems from planning to retirement is rapidly changing. Making a technology decision that can be justified and explained in terms of outcomes and benefits can be increasingly challenging without a systematic approach underlying the decision making process. It is proposed that better, more informed cloud adoption decisions would be taken if organisations used a structured approach to frame the problem to be solved and then applied trade-offs using an a

Abstract:

Molntjänster är något som på senare år blivit allt mer populärt. Det finns många fördelar med användandet av molntjänster, så som flexibelt arbete och rörliga kostnader. Vilka risker finns det då när en kund går från en molntjänstleverantör till en annan? I denna studie identifieras och analyseras olika risker vid byte av molntjänstleverantör. Studien undersöker även vilka åtgärder som kan utföras för att minimera dessa risker. Under studien utförs tre olika intervjuer med respondenter som har olika roller inom olika organisationer. Resultatet från intervjuerna analyseras därefter mot tidigare

Cloud computing is here to stay and is the natural progression in the evolution of our computing and collaboration needs. The easy availability of computing infrastructures is motivating a new breed of entrepreneurs to realize their ideas and deliver innovations to masses. These innovations, however, have some serious security weaknesses. If not taken into account, these weaknesses could prove fatal for an organization’s reputation and existence.

Abstract:

In the last few years, information and communication technologies (ICT) become increasingly important for enterprises. The constant intensification of technological needs, combined with the market renewal generated an increase in requests for information services and, as a consequence, an increase of the number of servers used in the companies data centers. This phenomenon generated a sharp increase in costs for companies that, not always, a corresponding improvement in terms of effectiveness and efficiency. More recently, companies approached to virtualization as data storage technique. The r

Abstract:

The main objectives of the thesis are to learn about the detection of a hypothetical marine cloud brightening (MCB) field experiment and to assess the benefits and risks of an actual implementation using model simulations. The first aim of the thesis is to assess the detectability of MCB from the natural variability of clouds using satellite data. The analysis uses two approaches, i) an analytical method, assessing the radiative forcing by aerosol-cloud interactions for an idealised perturbation of the droplet concentration and ii) a stochastic method, including the radiative forcing and the c

Hence, the security issues derived from cloud platforms are more serious, and this identifiable vulnerability risk classifies the threats path and identifies and assesses the possible attack path. Therefore, this paper utilizes the basis of Extended Attack Tree (EAT) Analysis and further proposes the Novel Attack Tree (NAT) Analysis scheme to calculate the threats and vulnerabili
