A Mechanism Of Tracking Data Usage Using Accountability Essay

Organizations use the Cloud in a variety of different service models (SaaS, PaaS, IaaS) and deployment models (Private, Public, Hybrid). There are a number of security issues/concerns associated with cloud computing but these issues fall into two broad categories: Security issues faced by cloud providers (organizations providing software-, platform-, or infrastructure-as-a-service via the cloud) and security issues faced by their customers.In most cases, the provider must ensure that their infrastructure is secure and that their clients’ data and applications are protected while the customer must ensure that the provider has taken the proper security measures to protect their information.

We would like to provide the benefits of cloud computing without any troubles to propel in the direction it is designed for. This is to be achieved by preventing the owner's data from all risks associated and providing a cloud model that is more secure and efficient. The proposed model shall overcome the security risks defined by the security functions over cloud computing, as follows in (Passent M. et al., 2015):

A significant paradigm shift is represented by public cloud computing from conventional norms of an organizational data center to a de-parameterized infrastructure which opens gates for potential adversaries to use. Cloud computing should be approached carefully with any emerging information technology area with due consideration to the sensitivity of data. A good planning helps and ensures that the computing environment is secure to the most possible extant and is in compliance with all relevant policies of an organization and makes sure the privacy is maintained.

The economic case for cloud computing is compelling and at the same time there are striking challenges in its security. The concepts of cloud computing security issues are fundamentally new and intractable. What appears new is only relative to traditional computing that has been practiced since several years. Many such security problems have been giving attention since the time-sharing era. Cloud computing providers have and can build datacenters as large due to their expertise in organizing and provisioning computational resources at as low cost as possible.

Imagine massive server failures that not only lead to complete data loss, but also a financial crisis for customers. This is the problem that Lloyds Banking Group faced when servers failed and left thousands of customers without access to their accounts according to Clarke (2014). In order to protect firm data, firm reputation, and especially customer trust and loyalty, Bank of America needs to assure proper precautions are taken to securely store all data.

Cloud computing has been around for over two decades, yet keeps evolving and growing in the scope of services available to businesses. With the allure of pay on demand and instantly scalable resources, cloud computing offers more services online than ever before and that kind of demand drives the need for data security.

This section of paper includes why we need cloud computing as a security control tool against the cyber criminal activities and in how many ways it can be implemented. As we are living in a technical era, many aspects of our lives rely on the Internet and computers, including transportation, communications, government, medicine, finance and education. Consider how much of our personal information is stored either on our own computer or on someone else’s system.

From the viewpoint of data security, which has always been an important form of quality of service, Cloud computing surely poses new challenging security threats for number of reasons. Firstly, traditional cryptographic primitives for the purpose of data security protection cannot be straight accepted due to users loss control of data under cloud computing. Therefore, verification of correct data storage in the cloud must be attended without accurate knowledge of the whole data. Considering different kind of data for every user stored in the cloud and the requirement of long term continuous security of their data safety, the problem of checking correctness of data storage in the cloud becomes even more challenging.[1]

Usage of remote servers via internet to store, manage and process data instead of using a personal computer is known as Cloud computing. It’s a set of Information Technology services with the ability to scale up or down their service requirements. Most of the cloud services are provided by a third party service provider. In cloud computing, organizations can utilize IT services without in advance investment. Despite its benefits obtained from the cloud computing, the organizations are slow in accepting it due to security issues and challenges. Security is one of the major problems which hinder the growth of cloud. It’s not wise to handing over the important data to another company; such that clients need to be vigilant in understanding the risks of data infringement in this new environment. This paper discusses a detailed analysis of the cloud computing security issues and challenges. (Ayoleke)

Cloud Services have become more popular as they provide a lot of advantages like high speed processing ,Flexibility and Disaster recovery.The problem is Security of data and how to ensure that data being processed at the cloud is secure

Modern day computing systems rely on a distributed system for data, functions and services. Arguably all popular software such as Uber, Spotify, Facebook and Fitbit among others, host their data and applications on dedicated servers to allow for user access services through their devices. The challenge with server based systems is that the integrity and security of private data is left out to third parties, nowadays established as corporations who offer hosting services for applications database and file storage. The main advantage of cloud based models is that customers do not have to pay for the installation of data storage and processing capabilities for applications (Jadeja,

ABSTRACT: Cloud computing is a method of providing a set of shared computing resources that includes applications, computing, storage, networking, development, and deployment platforms as well as business processes. In cloud computing, data while transferring as well as storage, and get data back when it is needed there is no assurance about the security of that data stored and also it is not changed by the cloud or TPA. Therefore Security and control over data remain to play a significant role in plans for cloud computing initiatives. Existing research work earlier grant data integrity to be verified,but still there are different drawbacks, firstly basic and mostly needed authorization/authentication process is not present in between Cloud Service provider and TPA. Techniques like authentication and encryption are important, our system can provides those things for security issues. Second: in recent research POR protocol in which the verifier stores only a single cryptographic key, POR can only capable of detection of file corruption or loss, and not prevention. Maintaining the storages can be a tough task and second it requires high resource costs for the implementation. This paper, Propose a formal analysis method called full

While it is important to take advantages of could based computing by means of deploying it in diversified sectors, the security aspects in a cloud based computing environment remains at the core of interest. Cloud based services and service providers are being evolved which has resulted in a new business trend based on cloud technology. This paper presents a review on the cloud computing concepts as well as security issues inherent within the context of cloud computing.

Cloud computing has become so famous; there is much widespread news about the cloud these days. This is mainly because of the exponential shift of the business applications from traditional models of software towards the Internet, and now through mobile devices. Cloud computing is a model that uses the network of remote servers that has been hosted on the internet rather than on a specific hardware. This would enable a better shared pool for storing, accessing and processing of data. With the huge information being available in the internet, the security for cloud computing has been challenging and this paper would elucidates the security threats of cloud computing also stating the possible countermeasures for them.

Cloud computing [1][2] is an evolving computing paradigm in which resources of the computing infrastructure are provided as services over the Internet. However this paradigm poses many new challenges for data security and access control. Users outsource data for sharing on cloud servers. This data may not be within the same trusted domain as data owners and hence is susceptible to various malicious attacks. One of the most challenging ongoing issues in cloud computing are data security [3]and access control due to which most of the ongoing research is dedicated to mitigating these challenges. To ensure the confidentiality of sensitive user data against untrusted servers, existing work try to use cryptographic techniques like disclosing data decryption keys only to authorized users. However these solutions inexorably introduce heavy computation overhead on the data owner for key distribution and data management when fine-grained data access control is desired, and thus do not scale
