Cloud computing has created a remarkable paradigm shift in the IT industry and brought several advantages such as on-demand self-service, broad network access, resource pooling, rapid elasticity, and measured service. These advantages enabled cloud to have significant impact on different sectors of smart cites. However, cloud adoption has increased the sophistication of the ever changing security risks which frustrate enterprises on expanding their on-premises infrastructure towards cloud horizons. These risks have the potential of being a major concern for smart cities due to the increasing impact of cloud on them. Managing these security risks requires adopting effective risk management method which involve both the cloud service provider and the customer. The risk management frameworks currently applied to manage enterprise IT risks do not readily fit the cloud environment and the dynamic nature of clouds, which are characterized by on demand self-service and rapid elasticity. Therefore, researchers have proposed different cloud security risk management methods and frameworks. This paper critically reviews these risk management methods and frameworks. In addition, it conducts critical analysis on two of them using qualitative content analysis technique, and evaluates their effectiveness for assessing and mitigating cloud security risks. Keywords-cloud security risk management; cloud security risk assessment; security risk management; cloud security riskI.

Purpose -This paper explores the use of Soft Systems Methodology (SSM) to analyse the sociotechnical information security issues in a major bank.Design/methodology/approach -Case study research was conducted on a major bank. Semistructured interviews with a purposive sample of key stakeholders in the business, comprising senior managers, security professionals and branch employees were conducted.Findings -SSM was particularly useful for exploring the holistic information security issues, enabling models to be constructed which were valuable analytical tools and easily understood by stakeholders, which increased the receptiveness of the bank, and assisted with member validation.Significant risks were apparent from internal sources with weaknesses in aspects of governance and security culture.Research limitations/implications -This research uses a single case study and whilst it cannot be generalised, it identifies potential security issues others may face and solutions they may apply.Practical implications -Information security is complex and addresses technical, governance, management and cultural risks. Banking attacks are changing, with greater focus on employees and customers. A systemic approach is required for full consideration. SSM is a suitable approach for such analysis within large organisations.Originality/value -Demonstrates how important benefits can be obtained by using SSM alongside traditional risk assessment approaches to identify holistic security issues. A holistic approach is particularly important given the increasing complexity of the security threat surface. Banking was selected as a case study since it is both critical to society and is a prime target for attack. Furthermore, developing economies are under-represented in information security research, this paper adds to the evidence base. Since global finance is highly interconnected, it is important that banks in such economies do not comprise a weak link and hence results from this case have value for the industry as a whole. | P a g e
