Security and Privacy Solutions in Cloud Computing at Openstack to Sustain Use...Zac Darcy
Cloud computing is an emerging model of service provision that has the advantage of minimizing costs
through sharing and storage of resources combined with a demand provisioning mechanism relying on
pay-per-use business model. Cloud computing features direct impact on information technology (IT)
budgeting but pose detrimental impacts on privacy and security mechanisms especially where sensitive
data is to be held offshore by third parties. Even though cloud computing environment promises new
benefits to organizations, it also presents its fair share of potential risks. It is considered as a double edge
sword considering the privacy and security standpoints. However, despite its potential to offer a low cost
security, customer organizations may increase the risks by storing their sensitive information in the cloud.
Therefore, this study focuses on privacy and security issues that pose a challenge in maintaining a level of
assurance that is sufficient enough to sustain confidence in potential users.
In this study, survey questions were sent to different non-profit and government organizations, which
assisted in collecting fundamental information. The data was acquired by conducting surveys in OpenStack
Company to identify the critical vulnerabilities in the cloud computing platform in order to provide the
recommended solutions.
So, analysis will be made on how the cloud’s characteristics such as the nature of the architecture,
attractiveness, as well as, vulnerability are tightly related to privacy and security issues. Privacy and
security are complex issues for which there is no standard and the relationship between them is necessarily
complicated. The study also highlight on the inherent challenge to data privacy because it typically results
in data to be presented in an encryption from the data owner. Thus, the study aimed at obtaining a common
goal to provide a comprehensive review of the existing security and privacy issues in cloud environments,
and identify and describe the most representative of the security and privacy attributes and present a
relationship among them.
Finally, in order to ensure that the standard measure of validity is achieved, validity test was conducted in
order to ensure that the study is free from errors. Various recommendations were provided. The study also
explored various areas that require future directions for each attribute, which comprise of multi-domain
policy integration and a secure service composition to design a comprehensive policy-based management
framework in the cloud environments.
Lastly, the recommendations will provide the potential for security and privacy approaches that can be
implemented to improve the cloud computing environment to ensure that a level of trust is achieved

HIGH LEVEL VIEW OF CLOUD SECURITY: ISSUES AND SOLUTIONScscpconf
In this paper, we discuss security issues for cloud computing, Map Reduce and Hadoop
environment. We also discuss various possible solutions for the issues in cloud computing
security and Hadoop. Today, Cloud computing security is developing at a rapid pace which
includes computer security, network security and information security. Cloud computing plays a
very vital role in protecting data, applications and the related infrastructure with the help of
policies, technologies and controls.
Data centers are growing to accommodate more internet-connected devices, with innovations helping achieve network coverage for billions of devices by 2020. As data centers grow, trends like software-driven infrastructure, microtechnology, and alternative energy use are making data centers more efficient by consolidating resources and reducing size. Hyperconvergence allows more efficient use of rack space by consolidating computer storage, networking, and virtualization in compact 2U systems from companies like Simplivity and Nutanix.

This document provides an overview of cloud computing, including definitions, advantages, disadvantages, and recommendations. It defines cloud computing as networked computer resources that can be accessed remotely through the internet. Key advantages include cost savings, scalability, device/location independence, and shared infrastructure. Disadvantages include loss of governance, lock-in effects, and security/isolation risks from shared multi-tenant systems. The document recommends approaches like standard checklists to help assess risks and obtain assurances when adopting cloud services.
This document summarizes a research paper that proposes a system for privacy-preserving public auditing of cloud data storage. The system allows a third-party auditor (TPA) to verify the integrity of data stored with a cloud service provider on behalf of users, without learning anything about the actual data contents. The system uses a public key-based homomorphic linear authenticator technique that enables the TPA to perform audits without having access to the full data. This technique allows the TPA to efficiently audit multiple users' data simultaneously. The document describes the system components, methodology used involving key generation and auditing protocols, and concludes the proposed system provides security and performance guarantees for privacy-preserving public auditing of cloud data
Authenticated and unrestricted auditing of big data space on cloud through v...IJMER
Cloud unlocks a different era in Information technology where it has the capability of providing the customers with a variety of scalable and flexible services. Cloud provides these services through a prepaid system, which helps the customers cut down on large investments on IT hardware
and other infrastructure. Also according to the Cloud viewpoint, customers don’t have control on their
respective data. Hence security of data is a big issue of using a Cloud service. Present work shows that
the data auditing can be done by any third party agent who is trusted and known as auditor. The auditor can verify the integrity of the data without having the ownership of the actual data. There are many disadvantages for the above approach. One of them is the absence of a required verification procedure among the auditor and service provider which means any person can ask for the verification of the file which puts this auditing at certain risk. Also in the existing scheme the data updates can be
done only for coarse granular updates i.e. blocks with the uneven size. And hence resulting in repeated communication and updating of auditor for a whole file block causing higher communication costs and
requires more storage space. In this paper, the emphasis is to give a proper breakdown for types of
fixed granular updates and put forward a design that will be capable to maintain authenticated and unrestricted auditing. Based on this system, there is also an approach for remarkably decreasing the communication costs for auditing little updates

Lifting the Corporate Veil. Power Point Presentationseri bangash
"Lifting the Corporate Veil" is a legal concept that refers to the judicial act of disregarding the separate legal personality of a corporation or limited liability company (LLC). Normally, a corporation is considered a legal entity separate from its shareholders or members, meaning that the personal assets of shareholders or members are protected from the liabilities of the corporation. However, there are certain situations where courts may decide to "pierce" or "lift" the corporate veil, holding shareholders or members personally liable for the debts or actions of the corporation.
Here are some common scenarios in which courts might lift the corporate veil:
Fraud or Illegality: If shareholders or members use the corporate structure to perpetrate fraud, evade legal obligations, or engage in illegal activities, courts may disregard the corporate entity and hold those individuals personally liable.
Undercapitalization: If a corporation is formed with insufficient capital to conduct its intended business and meet its foreseeable liabilities, and this lack of capitalization results in harm to creditors or other parties, courts may lift the corporate veil to hold shareholders or members liable.
Failure to Observe Corporate Formalities: Corporations and LLCs are required to observe certain formalities, such as holding regular meetings, maintaining separate financial records, and avoiding commingling of personal and corporate assets. If these formalities are not observed and the corporate structure is used as a mere façade, courts may disregard the corporate entity.
Alter Ego: If there is such a unity of interest and ownership between the corporation and its shareholders or members that the separate personalities of the corporation and the individuals no longer exist, courts may treat the corporation as the alter ego of its owners and hold them personally liable.
Group Enterprises: In some cases, where multiple corporations are closely related or form part of a single economic unit, courts may pierce the corporate veil to achieve equity, particularly if one corporation's actions harm creditors or other stakeholders and the corporate structure is being used to shield culpable parties from liability.

4. Some of the “Basics”
Become familiar with the language.
Become familiar with the business needs that drive
the differences between leases of data centers (on
the one hand) and leases of other real property,
such as office or warehouse space (on the other
hand).
Acknowledge the emerging, dynamic environment
in which data center leasing is occurring.

7. What are Data Center Leases “All About”?
Among the most prominent unique features found in
data centers are these (each of which will be discussed
in greater detail throughout this presentation):
· The importance of access to uninterrupted power;
· The importance of the space’s climate (temperature and humidity);
· The importance of the space’s data connectivity and data security;
· The importance of access issues (physical security); and
· The importance of the space’s physical integrity (think: natural
disaster).
8. FIVE TRENDS RELATED TO DATA
CENTERS
(Source: Cisco Global Cloud Index:
Forecast and Methodology, 2012-2017)
9. Growth of Global Data Center Relevance and Traffic
Since 2008, most Internet traffic has originated from or
terminated at a data center.
The increasing use of cloud computing is changing the
nature of data center traffic: Although increases in data
traffic across the Internet are occurring as might be
expected, there has been a sharp increase in traffic
among different units with a data center due to cloud-based
interaction.
Multiple factors are driving increased use of “the cloud”.
10. Continued Global Data Center Virtualization
Increases in server capacity and virtualization have resulted in a
cloud architecture that allows one physical server to handle
multiple times the workloads such servers handled in the past.
This approach results in multiple streams of data traffic within
and between data centers.
As a further illustration of the impact of the cloud, Cisco
estimates:
• That the ratio of workloads to non-virtualized traditional servers will grow from
1.7 in 2012 to 2.3 in 2017, while
• The ratio of workloads to non-virtualized cloud servers will grow at a greater
pace—from 6.5 in 2012 to 16.7 in 2017.
11. Growth in Demand for Data Storage and Access
Businesses are increasingly using solutions for data storage
and access that are cloud-based.
Individuals have an increasing expectation to be able to
store and access content.
12. The “Internet of Everything”
The quantity and complexity of communications among
people, data, and machines are rapidly increasing.
Cisco estimates:
• That machine-to-machine connections will grow from 2012 to 2022 at a rate
that is twenty-two times faster than the increase in the global population
over that period, and
• That by 2022, there will be 84 trillion data transmissions per year from
machines to other machines.
13. Increased Expectations Regarding Connectivity
Consumers of data storage and transmission services will
continue to demand improvements, world-wide, in
“connectivity”.
The metrics by which these improvements are measured
include:
• The ubiquity of broadband around the world;
• Increases in available download speed;
• Increases in available upload speed; and
• Improvements in network latency.
15. Remember “the Basics”?
Prominent, Unique Data Center Features:
· The importance of access to uninterrupted power;
· The importance of the space’s climate (temperature and humidity);
· The importance of the space’s data connectivity and data security;
· The importance of access issues (physical security); and
· The importance of the space’s physical integrity (think: natural disaster).
18. Power
Electricity powers servers.
Electricity powers redundancy equipment.
Other fuel further powers back-up generators.
The bottom line is that a lack of power means a server isn’t
functioning, which means that applications aren’t running and
data can’t be accessed, manipulated, or shared, and that
communications can’t occur.
19. Climate
Servers function most optimally under controlled temperature
and humidity circumstances.
Thus, electricity is not only critical for the reasons identified
on the previous slide, but also because electricity powers the
air conditioning units that create and maintain the proper
climate.
20. Data Connectivity and Data Security
As the prior discussion about trends illustrated, a
significant driver of growth in data center usage will be the
world’s expectations regarding access, use and security of
data.
A data center must have the physical connections that
allow the flow of data in and out of the data center.
A data center must also have the proper hardware,
software, and other safeguards necessary to protect the
housed data.
21. Physical Access to a Data Center
Efforts to digitally protect data would be useless if
the data center space could be easily accessed and
physically disturbed by trouble-makers.
Data centers employ a host of safeguards designed
to limit physical access to the data center space
generally and to certain servers specifically.
22. Physical Integrity
Data center operators attempt to avoid building
data centers in areas prone to flooding,
earthquakes, and/or other natural disasters.
These matters are less commonly addressed in data
center lease documents, but they are certainly
important deal considerations for data center users.
The importance of continuous operation is
illustrated by the rigorous terms of service level
agreement provisions (which will be discussed later
in this presentation).
