Security in the cloud is achieved, in part, through third party controls and assurance much like in traditional outsourcing arrangements. But since there is no common cloud computing security standard, there are additional challenges associated with this. Many cloud vendors implement their own proprietary standards and security technologies, and implement differing security models, which need to be evaluated on their own merits. In a vendor cloud model, it is ultimately down to adopting customer organizations to ensure that security in the cloud meets their own security polices through requirements gathering provider risk assessments, due diligence, and assurance activities. Privileged user access. Cloud providers generally have unlimited access to user data, controls are needed to address the risk of privileged user access leading to compromised customer data. Once data is stored in the cloud, the provider has access to that data and also controls access to that data by other entities(including other users of the cloud and other third party suppliers). Maintaining confidentiality of data in the cloud and limiting privileged user access can be achieved by legally enforcing the requirements of the cloud provider through contractual obligations and assurance mechanisms to ensure that confidentiality of the data is maintained to required standards. The cloud provider must have demonstrable security access control policies and technical solutions in place that prevent privilege escalation by standard users, enable auditing of user actions, and support the segregation of duties principle for privileged users in order to prevent and detect malicious insider activity. Data location and segregation. Customers may not know where their d... ... middle of paper ... ...ing. In a trusted computing environment, a trusted monitor is installed at the cloud server that can monitor or audit the operations of the cloud server. The trusted monitor can provide proof of compliance to the data owner, guaranteeing that certain access policies have not been violated. To ensure integrity of the monitor, trusted computing also allows secure bootstrapping of this monitor to run beside (and securely isolated from) the operating system and applications. The monitor can enforce access control policies and perform monitoring/auditing tasks. To produce a proof of compliance, the code of the monitor is signed, as well as a statement of compliance produced by the monitor. When the data owner receives this proof of compliance, it can verify that the correct monitor code is run, and that the cloud server has complied with access control policies.

This essay discusses regulation that rules cloud provider to protect privacy of data citizens within country. This essay will describe about what cloud services and its wide range of service In the second section, it will explain more about the security threat of cloud services and going more specific into privacy issue. The next section, I will discuss about the extent of technical regulation that porposed from case given by taking model from exist country regulation. In the Fourth section, this essay will discuss about evaluation and another policy as alternative of the previous policy. Finally, this essay will be closed by suggestion and conclusion about what regulation that should be purposed regarding to protect privacy citizens’ data stored in cloud.
The healthcare industry has access to a patient’s personal health information, in electronic and paper form, and is responsible for protecting this information. The Health Insurance Portability and Accountability Act (HIPAA) establish requirements for the healthcare industry. The establishment and implementation of an effective information security plan is critical to meet these requirements and ensure this protection. There are however challenges and risks that must be addressed. Cloud computing can be defined as the use of computer resources without the expense of owing the hardware and software. Cloud computing is becoming more and more popular in major corporations as a way to gain use of specific programs, applications and even hardware by way of the Internet.

It would be very difficult to ignore the potential benefits of cloud computing, but it also brings a number of new and worrying risks. Following are typical control requirements or opportunities that businesses may need to consider when considering a move to the cloud
In a local environment, access to the network machines is readily available, two examples of which are switches and routers. Access to all of the traffic passing through the network and analysis can be laboured as a part of gathering as much data as possible. When using the cloud, even the CSP (Cloud Services Provider) does not have that kind of data, because it must not log all the traffic passing through the network, since users’ data is confidential and CSP can’t record, store, and analyse it. The CSP might only apply the IDS (Intrusion Detection System) or PDS (Intrusion Prevention System) solution to the network, which is only analysing traffic for malicious behaviour and alerting the provider of such activity.
The main aim of this paper is to study the concept of cloud computing through virtualization, how security is compromised in cloud computing and how we can secure the system from security breach in case of virtualization.

To cater the wide variety of users, cloud is offering three types of services. These services include Infrastructure as a Service (IaaS), Platform as a Service (PaaS) and Software as a Service (SaaS) ( Mell & Grance, 2011). In IaaS users are offered the computing capabilities such as pr...
Discription: Services of cloud are used by both larger and smaller scale organizations.Cloud computing has huge advantages but it is a global phenomenon therefore it has some disadvantages. Both the Service providers and the consumers must work together to ensure safety and security of data on clouds. Customers of cloud services are in fear of data loss and privacy.This paper propose to use The Cloud Security Alliance (CSA) release of a new governance, risk management, and compliance stack for cloud computing. The cloud security tools are available for free download, is meant to help organizations create public and private clouds that act accordingly with industry standards for accepted governance, risk, and compliance (GRC) best practices. The GRC stack has three components: a controls framework, a technical foundation and a questionnaire for assessing what the CSA (cloud security alliance) calls for platform-, infrastructure- and software-as-a-service

Cloud computing is being heralded as the onrushing future of computing. In fact, in many ways, cloud computing is already here, and has been for some time. The most obvious example of cloud computing is Google Mail. Cloud computing, simply defined, is the implementation of computing services using shared hardware, shared software and in many cases even shared information. Google Mail, for example, makes e-mail services available using a widespread, highly redundant network of systems that remove that same functionality and data from the user’s computer, putting it “in the cloud” where it can be plucked back out as needed – from any capable device such as a smart phone, computer or internet kiosk.
Cloud computing facilitates sharing of computing and storage resources with the aim of reducing computing expenses in organizations. Moreover, cloud computing facilitates information sharing among individuals within a cloud. Despite being advantageous, data stored in a cloud is usually prone to hacking and other security issues. This paper addresses the various mitigation measures that organizations are using to ensure that data stored in the cloud is secure.

But, if the intruder gets the algorithm of the sentinel application on data, then the data can be breached easily. Hence, it appeared ineffective in due course of time. Thus a need of specific system rose to have such process which can monitor the cloud without adding any sentinels. Hence, demand of more improvised Auditor emerged which can provide effective integrity assurance for database services. Due to absence of such Auditor, have led to many inevitable situations, for example, recently a big robbery of data had occurred in the South Korea of three major banks. It had shown major drawbacks in the security and storage mechanism of IT infrastructure. The data which was robbed contained information like monthly card usage, card numbers, salaries etc, which had led to a lot of tension among the account holders. The card holders were running towards the bank for cancelling the card, so that no money from their account could be transferred. This episode pro-vided a lesson to keep the storage servers watertight, protected and detect prohibited action of culprits. In IT industry, large improvements in authentication system, firewalls and data access has to be made to avoid such incident in future. The presented work checks the integrity of data, so that no part of data could be modified, deleted and inserted without user permission. This paper provides users, the freedom of examining the integrity which observes indifferently toward both Cloud service providers (CSP) as well Data Owners. Monitoring of data needs requires profound study of database storage as well as methods of data transfer and access which is a very complex job. The methods must be reliable and must be transparent so that questions will not arise on the way of work...
