Cloud computing has been developed to reduce IT
expenses and to provide agile IT services to individual users as
well as organizations. It moves computing and data away from
desktop and portable PCs into large data centers. This
technology gives the opportunity for more innovation in
lightweight smart devices and it forms an innovative method of
performing business. Cloud computing depends on the internet
as a medium for users to access the required services at any time
on pay-per-use pattern. However this technology is still in its
initial stages of development, as it suffers from threats and
vulnerabilities that prevent the users from trusting it. Various
malicious activities from illegal users have threatened this
technology such as data misuse, inflexible access control and
limited monitoring. The occurrence of these threats may result
into damaging or illegal access of critical and confidential data of
users. This research paper describes the characteristics (threats,
vulnerabilities) associated with a stormy cloud.

MIST Effective Masquerade Attack Detection in the CloudKumar Goud
Abstract: Cloud computing promises to significantly change the way we use computers and access and store our personal and business information. With these new computing and communications paradigms arise new data security challenges. Existing data protection mechanisms such as encryption have failed in preventing data theft attacks, especially those perpetrated by an insider to the cloud provider. We propose a different approach for securing data in the cloud using offensive decoy technology. We monitor data access in the cloud and detect abnormal data access patterns. When unauthorized access is suspected and then verified using challenge questions, we launch a disinformation attack by returning large amounts of decoy information to the attacker. This protects against the misuse of the user’s real data. Experiments conducted in a local file setting provide evidence that this approach may provide unprecedented levels of user data security in a Cloud environment.

SECURITY APPREHENSIONS IN DIFFERENT REGIONS OF CLOUD CAPTIOUS GROUNDSIJNSA Journal
Cloud computing is a new innovative model for enterprise in which information is permanently stored on the servers and also manage how and when different resources are allocate to the requested users. It provides distributed approach through which resources are allocated dynamically to the users without investing in the infrastructure or licensing the software’s on the client side. Using the cloud makes processing of information is more commodious but it also present them with new security problems about reliability.This phenomenon introduces serious problems regarding access mechanism to any information stored in the database and resources in the cloud. For the successful implementation of cloud computing it is necessary that we must know different areas where the security is needed. For this there should also governess strategy needed for secure communication between multi-clouds located in different geographical areas or in different countries. In this paper we discuss how to safely utilizing the benefit of cloud computing through the network where data security, provide authentication, integration, recovery, IP spoofing and Virtual Servers are the most captiousfields in the cloud.
Data Stream Controller for Enterprise Cloud ApplicationIJSRD
Cloud computing is an emerging computing paradigm where computing resources are provided as services over Internet while residing in a large data center. Even though it enables us to dynamically provide servers with the ability to address a wide range of needs, this paradigm brings forth many new challenges for the data security and access control as users outsource their sensitive data to clouds, which are beyond the same trusted domain as data owners. The occupier need not be concerned with how the Paas system achieves expansion under high load.MAC systems differ as security policy is defined for the entire system, typically by administrators. Information flow control (IFC) is a MAC approach, developed originally from military information management methodologies. IFC can be used to enforce more general policies, using appropriate labeling and checking schemes. The labels can be used to manage both confidentiality and integrity concerns, tracking “secrecy†and “quality†of data, respectively. Decentralized Information Flow Control (DIFC) is an approach to security that allows application writers to control how data flow between the pieces of application and the outside world. As applied to privacy DIFC allows un trusted software to compute with private data while trusted security code controls the release of that data. As applied to integrity DIFC allows trusted code to protect un trusted software from unexpected inputs.
This document discusses challenges in information assurance and authentication. It introduces common web authentication methods like SAML and Shibboleth that enable single sign-on across domains using federated identity. SAML allows sharing of authentication and authorization data in XML format. Shibboleth is an open source single sign-on system that uses SAML and allows identity federations. OpenID is also discussed as a decentralized authentication standard used by many websites. The document compares and contrasts these different authentication methods.
Trust based Mechanism for Secure Cloud Computing Environment: A Surveyinventionjournals
Ubiquitous computing has revolutionized interaction of humans and machines. Cloud computing has been mainly used for storing data and various computational purposes. It has changed the face of using the internet. But, as we know every technology has its pros and cons. Securing cloud environment is the most challenging issue for the researchers and developers. Main aspects which cloud security should cover are authentication, authorization, data protection etc. Establishing trust between cloud service providers (CSP) is the biggest challenge, when someone is discussing about cloud security. Trust is a critical factor which mainly depends on perception of reputation and self-assessment done by both user and CSP. The trust model can act as security strength evaluator and ranking service for cloud application and services. For establishing trust relationship between two parties, mutual trust mechanism is reliable, as it does verification from both sides. There are various trust models which mainly focuses on securing one party i.e., they validate either user or service node. In this survey paper, the study of various trust models and their various parameters are discussed.

It emphasizes the importance of strong passwords and changing them regularly.
E-COMMERCE SYSTEMS SECURITY FOR SMALL BUSINESSESIJNSA Journal
Small business e-commerce websites make an excellent target for malicious attacks. Small businesses do not have the resources needed to effectively deal with attacks. Large and some mid-size organization have teams that are dedicated to dealing with security incidents and preventing future attacks. Most small businesses do not have the capabilities of dealing with incidents the way large organizations do. Security of e-commerce websites is essential for compliance with laws and regulations as well as gaining and maintaining the trust of consumers, partners and stakeholders. Many security standards have been established by various organizations to help guide security of small business servers, however, many of those standards or guidelines are too costly or time consuming. This paper1 will discuss how attacks are carried out and how a small business can effectively secure their networks with minimum cost.

IRJET- An Effective Protection on Content based Retrieval in Cloud StorehouseIRJET Journal
This document discusses content-based retrieval in cloud storage and proposes an effective protection method. It begins with background on cloud computing and discusses traditional encrypted search methods and their limitations, including vulnerabilities to attacks. The proposed system design generates an order-preserving encrypted password and splits files and indexes into encrypted parts. It then splits an uploaded secure image into a source image and key image using a binocular visual cryptography algorithm. The encrypted files, source image, and password are stored in the cloud. When a user requests a file, the cloud verifies and sends the password and key image. To access the file, the user must submit the matching key image. This prevents unauthorized access while allowing efficient encrypted searching and retrieval from the cloud.

INTRODUCTION
IJ
A
I.
The traditional era of computing involves the use of
software, hardware and storage to achieve the required
computational service whereas cloud computing has isolated
the services from resources (networks, storage, servers). The
required services are provided to the users by utilizing the
resources of provider. Users are no longer required to
purchase hardware, software or to manage storages. Due the
evolution of this technology users are required to pay for
cloud services on consumption basis. New cloud based
business models are being discussed, defined, and
implemented as solutions in form of on-demand services that
allows businesses to enhance their efficiency and scalability.
Success or failure of this technology relies on users’ trust
whether the service provided is reliable, available and secure.
Considering the benefits of cloud computing various
organizations are moving towards IT solutions that are based
on cloud however, before starting the journey to cloud,
organizations must considers the possible threats and
vulnerabilities that may convert their dreams of enhancing
scalability and saving management cost into a nightmare of
data loss and misuse. The users must consider that cloud can

be rainy as well, in other words this technology is not
trustworthy as it is affected with threats and vulnerabilities.
We have termed a cloud with threats and vulnerabilities as a
stormy cloud. Based on Cloud Security Alliance (CSA) and
our research, we have identified top seven threats and
vulnerabilities that are the causes behind the creation of a
stormy cloud [1]. The identified threats and vulnerabilities are
ranked from top to bottom as shown in Fig.1.

Abstract— Cloud computing has been developed to reduce IT
expenses and to provide agile IT services to individual users as
well as organizations. It moves computing and data away from
desktop and portable PCs into large data centers. This
technology gives the opportunity for more innovation in
lightweight smart devices and it forms an innovative method of
performing business. Cloud computing depends on the internet
as a medium for users to access the required services at any time
on pay-per-use pattern. However this technology is still in its
initial stages of development, as it suffers from threats and
vulnerabilities that prevent the users from trusting it. Various
malicious activities from illegal users have threatened this
technology such as data misuse, inflexible access control and
limited monitoring. The occurrence of these threats may result
into damaging or illegal access of critical and confidential data of
users. This research paper describes the characteristics (threats,
vulnerabilities) associated with a stormy cloud.

CLOUD COMPUTING THREATS
As we already mentioned, there are several significant
threats that should be considered before adopting the paradigm
of cloud computing, these threats are discribed as follows :
A. Abuse and Nefarious Use of Cloud
Cloud providers facilitate the users with various types of
services including unlimited bandwidth and storage capacity.
Some cloud service providers offer free limited trial periods
that gives an opportunity for hackers to access the cloud
immorally, their impact includes decoding and cracking of
passwords, launching potential attack points and executing
malicious commands. Spammers, malicious code authors and
other cybercriminals can conduct their activities with relative
impunity, as cloud service providers are targeted for their
weak registration systems and limited fraud detection
capabilities. For example some cybercriminals use rich
content applications such as flash files that enable them to
hide their malicious code and utilize users’ browsers to install
malware [1].
D. Virtualized Technology
Due to the cloud virtualization, cloud providers are residing
the user’s applications on virtual machines (VMs) within a
shared infrastructure. The VMs are virtualized based on the
physical hardware of cloud provider. In order to maintain the
security of users, providers are isolating the VMs from each
other so if any of them is malicious, it will not affect the other
VMs under the same provider. The VMs are managed by
hypervisor in order to provide virtual memory as well as CPU
scheduling policies to VMs. As the hypervisor is main source
of managing a virtualized cloud platform, hackers are
targeting it to access the VMs and the physical hardware,
because hypervisor resides between VMs and hardware [3], so
attack on hypervisor can damage the VMs and hardware.
Strong isolation should be employed to ensure that VMs are
not able to impact or access the operations of other users
running under the same cloud service provider. Several
vendors such as Xen and KVM are providing strong security
mechanisms of securing the cloud hypervisors, but still it is
identified that sometimes security of VMs is compromised.
E. Data Loss or Leakage
Data loss can occur due to operational failures, unreliable
data storage and inconsistent use of encryption keys.
Operational failure refers to deletion or alteration of records
without a backup of the original content that can take place
intentionally or unintentionally. Unreliable data storage refers
to saving of data on unreliable media that will be
unrecoverable if data is lost [4]. The inconsistent use of
encryption keys will result into loss and unauthorized accesses
of data by illegal users that will lead to the destruction of
sensitive and confidential information. Example of data loss
is Twitter hacks. The online accounts of Twitter accessed by
hackers and their numerous sensitive corporate documents
were stolen. These documents were housed in Google's online
web office service Google Docs. Although Google was not the
one to be blamed for security break-in as the security of
documents from twitter was not efficient enough. Instead, the
entire company data was only one password crack away from
discovery [5]. It’s clear from this example that data loss or
leakage can damage one’s brand, reputation and cause a loss
that may significantly impact employee, partner and users’
morale as well as trust. Loss of core intellectual property can
have competitive and financial implications beside the
compliance violations and legal consequences.
IJ

ES
B. Insecure Interfaces and APIs
Cloud users are using software interfaces and APIs to
access and manage the cloud services. These APIs need to be
secured because they play an integral part during provisioning,
management, orchestration and monitoring of the processes
running in a cloud environment. The security and availability
of cloud services is dependent upon the security of these APIs
so they should include features of authentication, access
control, encryption and activity monitoring. APIs must be
designed to protect against both accidental and malicious
attempts to avoid threats. If cloud service provider relies on
weak set of APIs, variety of security issues will be raised
related to confidentiality, integrity, availability and
accountability such as malicious or unidentified access, API
dependencies, limited monitoring/logging capabilities,
inflexible access controls, anonymous access, reusable
tokens/passwords and improper authorizations[1].
insider attacks can damage the financial value as well as brand
reputation of an organization.
T
II.
C.
Malicious Insider
Insider attacks can be performed by malicious employees at
the provider’s or user’s site. Malicious insider can steal the
confidential data of cloud users. This threat can break the trust
of cloud users on provider. A malicious insider can easily
obtain passwords, cryptographic keys and files. These attacks
may involve various types of fraud, damage or theft of
information and misuse of IT resources. The threat of
malicious attacks has increased due to lack of transparency in
cloud provider’s processes and procedures [2]. It means that a
provider may not reveal how employees are granted access and
how this access is monitored or how reports as well as policy
compliances are analyzed. Additionally, users have little
visibility about the hiring practices of their provider that could
open the door for an adversary, hackers or other cloud intruders
to steal confidential information or to take control over the
cloud. The level of access granted could enable attackers to
collect confidential data or to gain complete control over the
cloud services with little or no risk of detection. Malicious
ISSN: 2230-7818
F.
Account or Service Hijacking
Account or service hijacking refers to unauthorized access
gained by attackers to control the users’ accounts, such as
phishing, fraud and exploitation of software vulnerabilities.
For example if an attacker gains access to users’ credentials,
they can spy on their activities/transactions, manipulate their
data, return falsified information and redirect them to
illegitimate sites [6]. Users’ account or service instances may
become a new base for the attackers who can leverage the

cloud service providers’ reputation by launching subsequent
attacks. With stolen credentials, attackers can often access
critical areas of deployed cloud computing services, allowing
them to compromise the confidentiality, integrity and
availability of those services. Authentication and authorization
through the use of roles and password protecting is a common
way to maintain access control when using web-browsers to
access cloud computing systems. However, this method is not
sufficient enough to secure sensitive and critical data.

CLOUD COMPUTING VULNERABILITIES
Figure 2. VM Escape.
It allows the attacker to access the host OS and all other
VMs running on that particular host. Hypervisors and VM’s
complexity may cause an increase threat to attack surface that
weakens security such as paging, check pointing and
migration of VMs [8].
ES
There are several significant vulnerabilities that should be
considered when an organization is ready to move their critical
applications and data to a cloud compuitng environment, these
vulnerabilities are discribed as follows :
T
Unknown Risk Profile
It is important for the users to know software versions,
security practices, code updates and intrusion attempts. While
adopting cloud computing services, these features and
functionality may be well advertised but what about the details
or compliance of the internal security procedures,
configuration hardening, patching, auditing and logging. Users
must be clarified how and where their data and related logs are
stored. However, there is no clear answer that leaves users
with an unknown risk profile that may include serious threats
[1].
the VM within the virtualized cloud environment.VM escape
is a vulnerability that enables a guest-level VM to attack its
host. Under this vulnerability an attacker runs code on a VM
that allows an OS running within it to break out and interact
directly with the hypervisor as shown in Fig.2 [8].

A. Session Riding and Hijacking
Session hijacking refers to use of a valid session key to gain
unauthorized access for the information or services residing on
a computer system, it also refers to theft of a cookie used to
authenticate a user to a remote server and it is relevant to web
application technologies weaknesses in the web application
structure at their disposal that gives the chance to hackers in
order to accomplish a wide variety of malicious activities.
While session riding refers to the hackers sending commands
to a web application on behalf of the targeted user by just
sending that user an email or tricking the user into visiting a
specially crafted website. Session riding deletes user data,
executes online transactions like bids or orders, sends spam to
an intranet system via internet and changes system as well as
network configurations or even opens the firewall [12].
However, the web technologies evolution and refinement also
brings new techniques that compromise sensitive data, provide
access to theoretically secure networks and pose threats to the
daily operation of online businesses.
B. Virtual Machine Escape
Cloud computing servers use the same OS, enterprise and
web applications as localized VMs and physical servers. The
ability for an attacker or malware to remotely exploit
vulnerabilities in these systems and applications is a
significant threat to virtualized cloud computing environments
[7]. In addition, co-location of multiple VMs increases the
attack surface and risk of VM-to-VM compromise. Intrusion
detection and prevention systems need to be able to detect
malicious activity at VM level, regardless of the location of
ISSN: 2230-7818
C. Reliability and Availability of Service
In terms of reliability and availability, cloud computing is
not a perfect technology. For-example in February 2008,
Amazon's Web Service (Amazons-S3) cloud storage
infrastructure went down for several hours, causing data loss
and access issues with multiple Web 2.0 services. With more
services being built on top of cloud computing infrastructures,
an outage or failure can create a domino effect
by taking down large amounts of Internet based services and
applications which raise several questions such as in cases of
failure, what forms of settlement exist for stakeholders? What
is the responsibility of cloud providers? What will be
appropriate procedures to overcome these issues? [9].
D. Insecure Cryptography
Attackers’ can decode any cryptographic mechanism or
algorithm as main methods to hack them are discovered. It’s
common to find crucial flaws in cryptographic algorithm
implementations, which can twist strong encryption into weak
encryption or sometimes no encryption at all. For example in
cloud virtualization providers uses virtualization software to
partition servers into images that are provided to the users as
on-demand services [10]. Although utilization of those VMs
into cloud providers' data centres provides more flexible and
efficient setup than traditional servers but they don't have
enough access to generate random numbers needed to properly
encrypt data. This is one of the fundamental problems of
cryptography. How do computers produce truly random
numbers that can't be guessed or replicated? In PCs, OS

E. Data Protection and Portability
Although the cloud services are offered based on a contract
among client and a provider but what will happen when the
contract is terminated and client doesn’t wants to continue
anymore. The question is, will the sensitive data of client be
deleted or misused by the provider. Secondly if the provider
went out of business due to any reason, what will happen to
the services and data of the client? Will the provider handout
the data of client to some other provider, if yes, will client
trust the new provider? Considering these questions we can
say that data protection and portability remains as one of main
weaknesses of cloud computing.
believe there is still tremendous opportunity for researchers to
make revolutionary contributions in this field and bring
significant impact of their development to the industry. There
is need to develop and design in-depth security techniques and
policies in terms of people, processes and technology. By
considering the contributions from several IT industries
worldwide, it’s obvious that cloud computing will be one of
the leading strategic and innovative technologies in the near
future.

typically monitors users' mouse movements and key strokes to
gather random bits of data that are collected in a so-called
Entropy Pool (a set of unpredictable numbers that encryption
software automatically pulls to generate random encryption
passkeys). In servers, one that don't have access to a keyboard
or mouse, random numbers are also pulled from the
unpredictable movements of the computer's hard drive. VMs
that act as physical machines but are simulated with software
have fewer sources of entropy. For example Linux-based
VMs, gather random numbers only from the exact millisecond
time on their internal clocks and that is not enough to generate
strong keys for encryption [11].

F. Vendor Lock-in
This vulnerability occurs due to immature providers and
new business models which raise the risk of failure and going
out of the business. Lock-in, makes a client dependent on a
provider for products and services so they will be unable to
deal with another provider without substantial switching costs.
Clients must be sure of their potential provider prior to
provider selection process. Lack of standards may also lock-in
the clients with only one provider. Due to heterogeneous
standards and policies settled by each provider, clients are not
able to easily migrate from one provider to another even
though they want to do so [13].
G. Internet Dependency
Cloud computing is an internet dependent technology where
users are accessing the services via web browser. What if
internet is not available or service is down, what will happen
to users systems and operations that are very critical and need
to run 24 hours such as Healthcare and Banking systems. In
some Asian and African underdeveloped countries where
service of internet is not considered as reliable enough, will
organizations adopt this paradigm to move their significant
systems on cloud?

CONCLUSION AND FUTURE WORK
In this research paper we have discussed the characteristics
of a stormy cloud that contains threats and vulnerabilities.
Cloud computing has a dynamic nature that is flexible,
scalable and multi-shared with high capacity that gives an
innovative shape of carrying out business [14]. However,
beside these benefits there are seven deadly threats and
vulnerabilities encountered in this technology. Therefore, we
