Securing Cloud Computing

Cloud computing is the latest buzz words in computing. There is significant excitement about Cloud computing and this has been building up over the past few years. Cloud computing offers several great benefits which include cost savings and easy access to state of the art resources, however when considering deploying critical applications and sensitive information to a public cloud environment, security concerns are a big challenge. Recent study has shown that security, privacy and legal issues are the main obstacles to the adoption of cloud services. This thesis looks at how a cloud service user can constantly place a check on the cloud service provider with respect to data security and in cases where there has been a breach of security agreement, how these breach can be traced using forensic tools by the provider. We implement a virtual environment to showcase our proposed solution and configure security and test out deployment using a forensic tool (Forensic Tool Kit).

Development Strategy of SaaS Service based on User Behavior Analysis

The appearance and evolution of cloud service is potentially one of the major advances in information and communication technology. However, it is necessary to identify and understand the various issues of cloud service, both from the perspectives of the providers and the consumers of it. While a lot of studies such as cloud business model, profit model and technology itself are currently taking place in cloud service considering provider's aspects, there are a few researches dealing with cloud service user's aspects. This paper presents the user behavior analysis focused on SaaS users and discusses the development strategy of SaaS service based on the results of user behavior analysis. In order to analyze the user behavior, we surveyed SaaS users divided into two groups such as present and future user groups. Eventually, we proposed the SaaS prospects, development strategy and policy issues based on user behavior analysis.

A Panorama of Cloud Services

Cloud computing paradigm has attracted a lot of attention in the last five years as coming during an economic crisis with an appealing offer in reducing the infrastructure and maintenance costs. After first wave of enthusiasm in adopting the concept, a clearer image has been formed about the benefits and limitations of Cloud computing and a lot of different supporting technologies were developed. As consequence a new threat is raised by the high number of the proprietary technologies that makes difficult the decision of the proper technological selection according to the real business needs. In this context the aim of this paper is to offer a snapshot on the current concepts and the available technologies, especially of the ones that can allow the development of a solid market of Cloud services and applications. A particular attention is given to the trend of federating and brokering Cloud services in the process of forming new markets. Moreover, we propose a classification of groups of services from multiple Clouds based on models similar to the ones used in computer graphics to express colors. Furthermore, a technological solution aligned to the market requirements is presented as case study, pointing also to the role of open-source codes for promoting the Cloud service usage on large scale.

클라우드 컴퓨팅에서의 보안 고려사항에 관한 연구

클라우드 컴퓨팅은 컴퓨팅 리소스의 경비 절감과 효율은 물론 서비스의 확장 및 향상을 제공한다. 그러나 클라우드 서비스 사용자(기업 등)들은 클라우드 컴퓨팅 특성에 의한 여러 가지 위험들에 대해서 많은 염려를 갖고 있다. 본 논문에서는 클라우드 컴퓨팅 환경으로 인한, 시큐리티를 포함한 여러 가지 주요 이슈들을 검토하여 보고자 한다. 또한 시큐리티에 관한 문제들을 보다 구체적으로 분석하고 클라우드 컴퓨팅에 관한 위협들을 식별하여 시큐리티 위험을 줄일 수 있는 대략적인 대응책들을 제안하였다. Cloud computing provides not only cost savings and efficiencies for computing resources, but the ability to expend and enhance services. However, cloud service users(enterprisers) are very concerned about the risks created by the characteristics of cloud computing. In this paper, we discuss major concerns about cloud computing environments including concerns regarding security. We also analyze the security concerns specifically, identify threats to cloud computing, and propose general countermeasures to reduce the security risks.

Recent Advances in Cloud Security

Cloud computing emerges as a new computing paradigm which aims to provide reliable, customized and QoS guaranteed dynamic computing environments for end-users. Although cloud computing industry promises tremendous prospects of market growth, for users of cloud services, cloud computing has a wide range of potential risks and safety issues. This article gives a quick introduction to cloud security. It covers the key technologies of cloud computing, security challenge and problem in cloud computing, recent advances in cloud security.

Cloud Computing: Cloud Security to Trusted Cloud

Cloud computing, with exciting market prospects, has a number of potential risks and safety issues to the cloud services users. After an objective analysis of the security challenge and problem, in current cloud computing development, the latest research progress in the field of cloud security were summarized. Finally, the important research directions in the field were pointed out. It’s will be a new trend for the cloud computing and trusted computing technology to integrate..
