Security Concerns

For large-scale companies or people that desire a range of system services at a cheap cost, cloud computing is now the most popular phenomena to use. Personal information is frequently kept in a public cloud that is open to the public. This fundamental raises a number of concerns about cloud providers' flexible services, including confidentiality, persistence, and endurance. The paper aims to better understand cloud components, security concerns, and dangers, as well as developing solutions that might help minimise cloud vulnerabilities. It is a well-known truth that the cloud has been a viable hosting platform since 2008; nevertheless, the view of cloud security is that it requires major changes in order to achieve higher rates of adaptability at the corporate scale. Many of the difficulties affecting cloud computing need to be rectified immediately. The industry has made tremendous progress in combating cloud computing risks, but there is still work to be done to reach the level of maturity that traditional/on-premise hosting has.

Threat Modelling

The emergence of ecommerce almost three decades ago has completely transformed the approach to purchasing goods and services across various countries in the world. Almost every country in the globe, now have some form of ecommerce operations, this has further been enhanced by the stay at home COVID-19 induced lockdowns. The value and volume of transactions has also increased in transactions. However, there has been security concerns impacting ecommerce operations, which has in part, led to increasing adoption of hosting ecommerce systems in the public cloud. Threat modelling offer mechanisms to enhance the security of information technology (IT) systems. In this paper, we apply different threat modelling techniques to decompose the migration of an on-premise hosted ecommerce system to the public cloud and also evaluate these threat modelling techniques.

Cloud Computing Adoption

Cloud Computing is an increasingly important worldwide development in business service provision. The business benefits of Cloud Computing usage include reduced IT overhead costs, greater flexibility of services, reduced TCO (Total Cost of Ownership), on-demand services, and improved productivity. As a result, Small and Medium-Sized Enterprises (SMEs) are increasingly adopting Cloud Computing technology because of these perceived benefits. The most economical deployment model in Cloud Computing is called the Public Cloud, which is especially suitable for SMEs because it provides almost immediate access to hardware resources and reduces their need to purchase an array of advanced hardware and software applications. The changes experienced in Cloud Computing adoption over the past decade are unprecedented and have raised important issues with regard to privacy, security, trust, and reliability. This chapter presents a conceptual model for Cloud Computing adoption by SMEs in Australia.

The future of education lays in the hand of Cloud Computing given the benefits of learning delivery, costs reduction, and innovation. At the same time, the threat of cyber-attacks and security breaches are also mounting for education based organizations and are a prime target given the amount and type of personal information available. This manuscript discusses the cloud security, privacy, and ethical mechanisms required from a teacher, student, and administrator perspective.

Distinct Features

Fog computing is a term coined by networking giant Cisco. It is a new paradigm that extends the cloud computing model by conferring computation, storage, and application services at the periphery of networks. Fog computing is a gifted paradigm of cloud computing that facilitates the mobility, portability, heterogeneity, and processing of voluminous data. These distinct features of fog help to reduce latency and make it suitable for location-sensitive applications. Fog computing features raise new security concerns and challenges. The existing cloud security has not been implemented directly due to mobility, heterogeneity of fog nodes. As we know, IoT has to process large amount of data quickly; therefore, it has various functionality-driven applications that escalate security concerns. The primary aim of this chapter is to present the most recent security aspects such as authentication and trust, reputation-based trust model, rogue fog node and authentication at different level, security threats, challenges, and also highlights the future aspects of fog.

Computing Landscape

As we approach the limits of Moore’s law the Cloud computing landscape is becoming ever more heterogeneous in order to extract more performance from available resources. Meanwhile, the container-based cloud is of growing importance as a lightweight way to deploy applications. A unified heterogeneous systems framework for use with container-based applications in the heterogeneous cloud is required. We present a bytecode-based framework and it’s implementation called Man O’ War, which allows for the creation of novel, portable LLVM bitcode-based containers for use in the heterogeneous cloud. Containers in Man O’ War enabled systems can be efficiently specialized for the available hardware within the Cloud and expand the frontiers for optimization in heterogeneous cloud environments. We demonstrate that a framework utilizing portable bytecode-based containers eases optimizations such as heterogeneous scaling which have the potential to improve resource utilization and significantly lower costs for users of the public cloud.

Secure Server

The Enterprise Level Security (ELS) model focuses on designing secure, distributed web-based systems starting from basic principles. One area of ELS that poses significant design challenges is protection of web server private keys in a public cloud. Web server private keys are of critical importance because they control who can act as the server to represent the enterprise. This includes responding to requests as well as making requests within the enterprise and to its partners. The cloud provider is not part of this trusted network of servers, so the cloud provider should not have access to server private keys. However, current cloud systems are designed to allow cloud providers free access to server private keys. This paper proposes design solutions to securely manage private keys in a public cloud. An examination of commonly used approaches demonstrates the ease with which cloud providers can currently control server private keys. Two designs are proposed to prevent cloud provider access to keys, and their implementation issues are discussed.
