7.7.1 Data Owners 1. One whose going to access files, one who owns file, who requires his data to be secure. 2. Data owners are responsible for encrypting the data by generating private key. MMCOE, Department of Computer Engineering, 2015-2016 26 Regeneration of code based cloud storage 3. Data/File is encrypted using AES Algorithm. 4. Data owner sends data/file to TPA and takes help of TPA. 5. Data owner is provided with log window to see how TPA is working and get report of the same. 6. Data owner pays to TPA to get security of its data and can access valuable data at anytime. 7.7.2 Cloud Server 1. One whose going to access files, one who owns file, who requires his data to be secure. 2. Two different servers are used to store half half information …show more content…
TPA is responsible for splitting data/file into two parts so as to secure the data. 4. Attacker can attack either of the servers or both. Attacking both servers can be rare , there is a possibility of attacking one server at a time. 5. Ever since data is in encrypted format, its probably difficult for attacker to decode it ; but this will ultimately lead to data owner to suffer in one or the other way. 6. In order to solve this problem metadata is stored for each server content into proxy server. 7. Suppose size of data stored in server 1 is 2GB and similarly size of data stored in server2 is 2 GB. So backup of these two servers require 2GB space. 8. If we are using metadata to store backup of these servers it will probably require less storage size i.e less than 2 GB. 7.7.3 TPA(Third Party Auditor) 1. There are basically three types of audits product, process and system. Audits are name according to there purpose. 2. Audits are classified into internal or external, depending upon relationship of participants. 3. Internal audits are performed within an organization by employees. 4. External audits are performed by Third party agent or outside agents. 5. Audit is performed by an organization free from customer supplier
As the technology marches forward introducing every time we turn around a new, improved device or computer program this constant adaptation undoubtedly affects every part of our financial life. One must agree that iPhones, for example, which become almost absolute after two or three years of use due to evolving computer science must create an economic burden for some American families. The same way, all hospitals must struggle with maintaining technological sharpness while assuring the presence of digital innovation despite the existing financial limitations. To illustrate the monetary hindrance in the VA Hospital, I would like to bring to the attention a problem related to cloud-based application necessary for managing and storing information.
Figures 5.9, 5.10 and 5.11 illustrate the roles in NG-Cloud: User, Data Owner and Administrator Roles. Figure 5.9 Administrator Role Figure 5.10 User Role Figure 5.11 Data Owner Role 5.4 Security Functions Of The Proposed Model Our proposed model achieves the security functions. We implemented the security functions in the NG-Cloud simulation as following:
Main principles of the HIPAA rules: 1. Rules protect the interests of so-called “protected health information” (PHI), particularly data that helps to identify certain person. 2. The main goal of the HIPAA rules is detection and prevention of such circumstances that entail theft or disclosure of personal PHI. As a rule, health care organizations are not allowed to use or disclose PHI, with few exceptions.
For cloud consumers that have custom-built solutions with dependencies on these proprietary environments, it can be challenging to move from one cloud provider to another. Portability is a measure used to determine the impact of moving cloud consumer IT resources and data between clouds. 3.5.4 Multi-Regional Compliance and Legal Issues Third-party cloud providers will frequently establish data centers in affordable or convenient geographical locations. Cloud consumers will often not be aware of the physical location of their IT resources and data when hosted by public clouds. For some organizations, this can pose serious legal concerns pertaining to industry or government regulations that specify data privacy and storage policies.
Data security is usually one of the main priorities for corporate and small businesses. It is a type of security that protects data in databases from hackers or unauthorized users. These databases consist of financial information, sales numbers, and other key business information. The security provides privacy measures to prevent access and corruption to the company’s computers, databases, and websites.
Digital rights management is an industry technology that protects various forms of digital content such as financial reports, online digital music, electronic books, product specification, etc. DRM is essentially an access and usage control technology in the application level. Most people have heard of software licensing and digital library lending services but perhaps not related it with Digital Rights Management (DRM). The purpose of DRM is to prevent unauthorized access and redistribution of digital content and to restrict the customer from specific use activities like copying, sharing, and cut & paste.
First World Bank Savings and Loan has a requirement to read confidential customer data located in the local area network of their servers. First World Bank Savings and Loan needs to deliver highly confidential customer data in PDF format for its online customers in a timely manner. The information will be upload to the Linux file server by the bank employees within the local area network for further distribution. The customer need to be able to access this information but not be able to modify it. First World Bank Savings and Loan has several steps to make to make a secure set up.
The place where back up media can be kept is always secured. User Identification and Privileges Management Each and every user will be granted using special and unique end user
Besides that, to detect management fraud, external auditor must looking at the size of the client. If the client is a small size business, auditors need to aware that fraud management may be higher that big size business client. Because there is less to maintain audit committee in the small size business, therefore auditors need to advice the internal control to exercise audit committee in the management in order to prevent fraud an also perform more test of controls. While a big size company, auditors need
Data controllers have responsibilities; all data controllers must comply with certain important rules about how they collect and use personal information, some data controllers must register annually with the Data Protection Commissioner, in order to make transparent their data handling practices, this is mostly done if the data controller is responsible for personal information retaining to individuals. [9] Some companies only store personal data for other organisation; if a company does not decide or have any input in the use of the data, it only hold/stores that data and it is the organisation who controls the use of data, the company is called a data processor and the organisation is the data controller. Examples of data processors are payroll companies, accountants, market research companies and cloud storage providers; all store information on behalf of another company/organisation. Data processors have a very limited set of responsibilities under the Data Protection Act.
Cloud computing brings forward computing power and storage as a utility without having to pay for the huge upfront costs of owning racks of servers and hard drives. As companies are flocking to migrate their information and systems to cloud computing because of the reduced cost and increased reliability, privacy is an issue that emerges (Takabi, Joshi, & Ahn, 2010). The question of what information to put in the cloud and what is accessible to the internet becomes an issue that keeps managers and lawyers awake at night. Privacy concern and who is ultimately responsible for the information to ensure that the data remains private and does not violate laws is an issue between the cloud computing providers, the companies that want to move their aging infrastructure to cloud computing and regulatory bodies.

The average computer user has only a vague understanding of how their data is stored. They know they have this "hard drive thingy" inside the computer and they know that's where their data is kept. That's about as far as it goes for most users. Many don't even know what a hard drive looks like.
The author regards relevant data saying auditors are part of the organization who plays a role in strengthening internal control. Similarly, another study from the Committee of Sponsoring Organizations of the Treadway Commission (COSO) also reveals that internal auditors are responsible for the effectiveness of the control system only and effective communication that comes across and up the organization is the key for stronger internal control. (Committee of Sponsoring Organizations of the Treadway Commission (COSO) (n.d.)). Other than that, the author interprets that segregation of duties can enhance internal control.
Online communication becomes more common after the introduction of computers and the internet. People find it easy to exchange information electronically through email, fax, internet, and websites using computers and phones. Online communication is quick, convenient, and cheap, but risky when it comes to privacy. People share pictures, messages, medical information, shop online, and apply for jobs using the internet. For the last ten years, exchanging information using electronic format is gradually replacing paper format.
