...- 2011 Cloud Hooks: Security and Privacy Issues in Cloud Computing Wayne A. Jansen, NIST Abstract In meteorology, the most destructive extratropical cyclones evolve with the formation of a bent-back front and cloud head separated from the main polar-front, creating a hook that completely encircles a pocket of warm air with colder air. The most damaging winds occur near the tip of the hook. The cloud hook formation provides a useful analogy for cloud computing, in which the most acute obstacles with outsourced services (i.e., the cloud hook) are security and privacy issues. This paper identifies key issues, which are believed to have long-term significance in cloud computing security and privacy, based on documented problems and exhibited weaknesses. • applications can be developed upon and deployed. It can reduce the cost and complexity of buying, housing, and managing hardware and software components of the platform. Infrastructure-as-a-Service (IaaS) enables a software deployment model in which the basic computing infrastructure of servers, software, and network equipment is provided as an on-demand service upon which a platform to develop and execute applications can be founded. It can be used to avoid buying, housing, and managing the basic hardware and software infrastructure components. 1.

...Trust in Cloud Computing Sarah Kim University of Texas at Austin 1616 Guadalupe Suite #5.202 Austin, TX 78701-1213 srhkim@gmail.com ABSTRACT Ayoung Yoon University of North Carolina at Chapel Hill 216 Lenoir Dr. CB #3360 100 Manning Hall, Chapel Hill, NC 27599 ayyoon@email.unc.edu journalists, IT experts, and scholars have addressed challenges of trust in cloud computing often accompanied with concerns for security, privacy, diminishing user control, lack of transparency, and reputation issues (e.g., Ghosh & Arce, 2010; Kahn & Malluhi, 2010; Pearson & Benameur, 2010; Habib, Ries, & Muhlhauser, 2010). Many of the trust-related discussions, however, are often based on the viewpoints of service developers/providers or technology focused (e.g., Hwang & Li, 2010). Cloud service providers (CSPs) saying “trust me” does not necessarily motivate people to respond with “I trust you.” Understanding of users’ thoughts on trust issues in the cloud computing environment is necessary in order to build and preserve trust between users and cloud service providers. PURPOSE OF RESEARCH The present study explores individual end-users’ perspectives of cloud computing, especially issues regarding their trust/distrust of cloud services. While current cloud computing service development focuses on adoption by enterprises and organizations, individual endusers who use cloud services in their everyday lives also constitute an important consumer group. Challenges of trust in cloud computing have gained...

...STUDENT NUMBER: 066275 CLOUD COMPUTING SECURITY TERM PAPER TWO Living with Increasing Attacks on Cloud Computing Platforms Cloud Computing is an on demand, flexible and cost friendly delivery platform that has provided IT consumers and organizations services such as networks, storage, servers and applications over the Internet. Its importance is increasing as a large number of industrial and technological communities are rapidly adopting it. The benefits such as low cost and convenience of cloud computing services have significantly changed our day to days activities, however, there are numerous security issues facing cloud computing making it difficult to maintain data security and privacy, support data and service availability and demonstrate compliance. These issue also make cloud vulnerable to exploitation by attackers. The three cloud services models used today are Software as a Service (SaaS), Platform as a Service (PaaS) and Infrastructure as a Service (IaaS).Iaas provides the most dynamic functionality since it is based as the underlying layer in cloud. It widens the resilience for users to design a practical environment that includes virtual machines running with different operating systems. This may pose as a vulnerability since an attacker could lease these virtual machines, analyze their configurations, find their vulnerabilities, and attack other customers’ virtual machines within the same cloud. Brute force and Distributed denial of service (DDoS) attacks could...

...Cloud Computing Introduction Cloud computing is the idea of deploying groups of remote servers and software networks that allows remote access to computer resources. Cloud computing is the term that describes the delivery of computer as service rather than a product. The internet is like a cloud. Cloud computing users use the services of the computing. They don’t have ideas about the location of the computer infrastructure. Cloud computing provides computation, software, data access, and storage resources to its users. If businesses look for the computing services without establishing computing infrastructure, the cloud can be the solution to achieve the objective. How Cloud Computing works? Cloud computing changed the way of computer uses. It changed the concepts of use web and store the data. Cloud computing is the structure which was used by the sites like Google, Facebook, Twitter, Dropbox. Let’s consider that the cloud consists layers. There is the back-end layers and the front-end layers. Front-end is the public part and users can interact with the front end layer. For example, when we access on Google Drive, the public user interface is visible to us. The back-end consists of hardware and software architecture that delivers the data to the front-end. There are many computers integrated to work together in the cloud technology. The front-end application can use all available computer power to provide the services to end users. Cloud computing uses the network...

...INTRODUCTION Cloud computing has boost a large amount of interest in the IT industry. The market research and analysis firm IDC suggests that the market for cloud computing services was $16bn in 2008 and will rise to $42bn/year by 2012 (Chhabra, Verma &ump; Taneja, 2010) .The era of cloud computing introduces a new dimension for Enterprises. The academia and research worlds have developed a keen interest into challenges and issues introduced by this relatively new concept (Sriram &ump; Khajeh-Hosseini, 2009). As experienced by large or small companies while adopting cloud computing technology, the issues can be outlined as security, privacy, data migration as (Hosseini, et al., 2010 ). Adoption of cloud technology by enterprises especially those are using KBE (knowledge based engineering) systems are in risk in terms of migration their data over the cloud. Most enterprises are in a midst of creating, sharing, streaming and storing data in digital formats to allow collaboration , hence there is a need to continuously managed and protect the data to ensure its value and authenticity (Yale &ump; Chow, 2011). Enterprises now acquire increasingly more information about their products, customers and partners- whether it’s stored in a cloud environment or not and failure to protect this data can be damaging. Partners and clients anticipate their information will be constantly protected before conducting business with a company. Within lay the need for complete data governance to...

...Cloud Computing Introduction This term paper will describe the characteristics of Cloud Computing and services associated with it. It will cover how businesses deploy services such as Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS), as well as some of the benefits and challenges of Cloud Computing. Cloud Computing Definition - Cloud Computing is basically servers providing specific services to businesses and individuals over the internet. Characteristics * Shared Infrastructure — is when data centers use virtualization software on existing servers. This cuts down on total cost of infrastructure, storage, and networking bandwidth. * Dynamic Provisioning —Server computing instances or virtual machines are provisioned dynamically from a centralized console using automated software. The amount of services provided are determined by current demand requirements. * Network Access — One thing I like about Cloud Computing is the ability to access your account from anywhere, from any device. As long as you have an internet connection, you can use your pc, tablet, laptop, or mobile devices. An example is using iCloud storage to backup and restore your iphone. * Managed Metering — Another thing I like about Cloud Computing is you are only billed for what you use. Metering is used to optimize the service, provide reporting, and billing information. Service Models Once a cloud is established, how...
