云计算是一种新型的资源高效利用模式,它的高效率和高资源利用率使得云计算逐步成为信息时代的主流,然而随着云计算的横空出世,可信云计算、云计算安全的问题也纷至沓来。可信云计算技术与安全云计算技术两者既可以组合使用,也可以独立使用。它们共同构成了云计算网络安全技术。云计算网络安全技术的技术支撑是可信访问控制,密文检索与处理,数据存在与可使用性证明,数据隐私保护,虚拟安全技术,云资源访问控制等。可信云安全计算技术及其特征支撑着整个可信安全云系统,包括可信云服务数据中心、可信云用户端以及可信云管理平台。可以构建可信云安全技术的各应用系统,包括可信政务云系统、可信家务云系统、可信企业云系统、可信商务云系统。 相似文献

For many companies the remaining barriers to adopting cloud computing services are related to security. One of these significant security issues is the lack of auditability for various aspects of security in the cloud computing environment. In this paper we look at the issue of cloud computing security auditing from three perspectives: user auditing requirements, technical approaches for (data) security auditing and current cloud service provider capabilities for meeting audit requirements. We also divide specific auditing issues into two categories: infrastructure security auditing and data security auditing. We find ultimately that despite a number of techniques available to address user auditing concerns in the data auditing area, cloud providers have thus far only focused on infrastructure security auditing concerns. 相似文献

This paper presents a systematic approach to develop a resilient software system which can be developed as emerging services and analytics for resiliency. While using the resiliency as a good example for enterprise cloud security, all resilient characteristics should be blended together to produce greater impacts. A framework, cloud computing adoption framework (CCAF), is presented in details. CCAF has four major types of emerging services and each one has been explained in details with regard to the individual function and how each one can be integrated. CCAF is an architectural framework that blends software resilience, service components and guidelines together and provides real case studies to produce greater impacts to the organizations adopting cloud computing and security. CCAF provides business alignments and provides agility, efficiency and integration for business competitive edge. In order to validate user requirements and system designs, a large scale survey has been conducted with detailed analysis provided for each major question. We present our discussion and conclude that the use of CCAF framework can illustrate software resilience and security improvement for enterprise security. CCAF framework itself is validated as an emerging service for enterprise cloud computing with analytics showing survey analysis. 相似文献

Today’s data is sensitive that requires privacy and security both from the cloud service providers (CSP) as well as from users in its all the form of data states: data at rest, while transferring data, enquiring data, and processing the data. Cloud computing has been applied in the health sector, national security services, banking and other business and companies that store confidential data into the cloud as we have seen in recent years. Therefore, information and data security is a crucial issue that needs to be addressed thoroughly in the cloud computing business. This research deals with the performance analysis of recent cloud data security models. This paper proposes cloud data security models based on Business Process Modeling Notations (BPMN) and simulation results can reveal performances issues related to data security as part of any organizations initiative on Business process management (BPM). 相似文献

Cloud computing is a current trend that reveals the next-generation application architecture and it is estimated that by 2013 the cloud market will have reached $8.1bn. While cloud services such as webmail, Flickr and YouTube have been widely used by individuals for some time, it not until relatively recently that organisations have began to use cloud services as a tool for meeting their IT needs. This study aims to investigate how cloud computing is understood by IT professionals and the concerns that IT professionals have in regard to the adoption of cloud services. The study was carried out in Taiwan and used a survey by interview approach to understand IT professionals’ understandings and concerns about cloud computing. The findings of the study suggest that while the benefits of cloud computing such as its computational power and ability to help companies save costs are often mentioned in the literature, the primary concerns that IT managers and software engineers have are compatibility of the cloud with companies’ policy, IS development environment, and business needs; and relative advantages of adopting cloud solutions. The findings also suggest that most IT companies in Taiwan will not adopt cloud computing until the uncertainties associated with cloud computing, e.g. security and standardisation are reduced and successful business models have emerged. 相似文献

This article focuses on the role of accountability within information management, particularly in cloud computing contexts. Key to this notion is that an accountable Cloud Provider must demonstrate both willingness and capacity for being a responsible steward of other people's data. More generally, the notion of accountability is defined as it applies to the cloud, and a conceptual model is presented related to the provision of accountability of cloud services. This allows a consideration of accountability at various different levels of abstraction, including the operationalisation of accountability. It is underpinned by fundamental requirements for strong accountability, which in particular are aimed at avoiding risks in the provision and verification of accounts (that include different types of accountability evidence and notifications, that may need to be provided to other cloud actors including data subjects, cloud customers and regulators). In addition, the article sketches what kind of tools, mechanisms and guidelines support this in practice, and discusses these in the light of the upcoming European Data Protection Regulation. 相似文献
