Cybersecurity management has emerged as a topic of growing importance on a global scale. Applying traditional management practices to cybersecurity is often too cumbersome and can lead to significant delays. Today's enterprises must be able to adapt to ever-evolving digital threats and act with corresponding agility and flexibility. Agile methods are well suited for projects without a defined scope, duration, tasks, and resources and has been identified as suitable for meeting the management challenges of cybersecurity teams. Based on an in-depth literature review, this study assumed that adopting an agile approach to cybersecurity helps organizations manage cybersecurity effectively. A first prototypical model was developed and evaluated which combines agile methods with cybersecurity functions - based on a recognized reference model.

The field of cloud service selection tries to support customers in selecting cloud services based on QoS attributes. For considering the right, QoS attributes it is necessary to respect the customers and the providers’ perception. This can be made through a Service Quality Model. Thus, this paper introduces a Cloud Service Quality Model based on a Systematic Literature Review and user interviews as well as providers perceptions.

The digital age poses manifold challenges and difficult conditions for all sizes of organizations in all industries. Organizations need to adapt to complex challenges and difficult conditions and to plan and execute their digital transformation strategies. More and more organizations need support by strategic business consulting companies which must be offered in an effective and efficient way so that also small and medium sized companies can profit from it to stay competitive. Our research work focusses on the development of online strategic consulting tools offered as self-services on a web-based platform supporting the definition of digital transformation strategy. The so-called Digital Backpack Assessment (DBA) measures the digital maturity and proposes possible cases for changes. The tool follows the following principles: (1) A holistic approach with focus on the customer orientation, the business models, the organizational excellence, and the operational excellence. (2) An open strategy approach where several stakeholders from the company participate

Increased consciousness of cloud computing capabilities leads to greater adoption of the cloud. For many businesses, cloud computing represents an attractive cost-saving option for the establishment and maintenance of IT resources. Decision-makers are often confronted with multi-criteria decision issues regarding cloud service and deployment model selection and do not have the required technological and business-related background. This work aimed at developing a conversational decisions advisor in the form of the Cloud Advisor Bot to support complex assessment of cloud needs. The literature review revealed a gap in this domain as there is no pre-existing research in the area of chatbots that support the cloud assessment process. Based on the literature reviews as well as further research, it was investigated which elements needed to be developed in order to implement a prototype of the Cloud Advisor Bot. To achieve this, design science research was applied to iteratively develop the solution. The evaluation has shown that the prototype of the Cloud Advisor Bot can be successfully used in order to conduct an assessment regarding a possible cloud deployment scenario. The paper also proposes further developments in order to improve the solution and make it viable for the future

With the advent of Cloud Computing and the advantages it brings to businesses, there is a keen interest by businesses to adopt these technologies from a strategic advantage viewpoint. This growing interest throws up a challenge to businesses to identify solutions and providers that fits their requirements. It becomes difficult for them to locate and evaluate services provided by multiple Cloud Service Providers. This is exactly where the concept of an Electronic Marketplace for Cloud Services (EMPCS) would fit in. The Cloud Services Brokerage (CSB) or an intermediary is an enhanced type of EMPCS that simplifies the process further by a single-point, aggregated and customized solution. Using research literatures for reviewing existing models of an Electronic Marketplace (EMP) or Electronic Markets (EM) this research tries to identify core components that form part of a “state of the art” intermediary based EMP designed specifically for a Cloud Services.
