“Data in storage” of the Cloud environments are more “Vulnerable to Attacks.” Explained in the Technet magazine in July 2013 by Dan C. Marinescu, Professor of Computer Science, http://technet.microsoft.com/en-us/magazine/dn271884.aspx
The document summarizes the top threats to cloud computing as identified by the Cloud Security Alliance. It lists 7 top threats: 1) abuse and nefarious use of cloud computing, 2) insecure application programming interfaces, 3) malicious insiders, 4) shared technology vulnerabilities, 5) data loss/leakage, 6) account, service, and traffic hijacking, and 7) unknown risk profile. The threats are presented to provide context to help organizations make risk management decisions about cloud adoption strategies.
Technology will help fulfill information governance requirements in three key ways:
1) By providing solutions that can manage huge volumes of information across different operating systems and repositories with a single classification system and integration of services.
2) By enabling analysis, assessment, searching, and data mining of all content types and sharing of content across business applications, social networks, and devices.
3) By controlling access, ensuring data security and deletion, and certifying content integrity through total availability of services regardless of device.
Cloud Computing Security Threats and Responsesshafzonly
This document discusses security issues and threats in cloud computing, as well as responses to those threats. It introduces cloud computing and the types of cloud environments and services. It then covers key aspects of cloud security like reliability, availability, and security (RAS). Specific security issues are examined such as privileged user access, regulatory compliance, data location, and data segregation. Responses to threats are proposed, including access control, incident countermeasures, and workload analysis and allocation. The conclusion acknowledges that while providers can add resources to protect against attacks, powerful distributed denial of service attacks remain a challenge.

Cloud computing is the use of computing resources that are delivered as a service over the Internet. It allows users to access data, software and computing power remotely. There are several types of cloud platforms including Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). While cloud computing can improve security through centralization, users lose some control over sensitive data and security is complex with data distributed across multiple devices. Performance is monitored in cloud applications which are easier to maintain since they do not need to be installed locally on each user's computer.
This document defines cloud computing and its key characteristics. Cloud computing provides on-demand access to shared computing resources like networks, servers, storage, applications and services that can be quickly provisioned with minimal management effort. It has essential characteristics of on-demand self-service, broad network access, resource pooling, rapid elasticity, and measured service. There are three service models - Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS). Four deployment models of public, private, community and hybrid clouds are also defined.
Cloud computing is an internet-based computing technology, where shared re-sources
such as software, platform, storage and information are provided to customers on demand.
Cloud computing is a computing platform for sharing resources that include infrastructures,
software, applications, and business processes. The exact definition of cloud computing is A

Infographic - Cloud Hosting and Tenancy Jeff Davis
Infographic explaining the differences between private, public, and hybrid cloud hosting options and how they compare to dedicated, shared, and multi-tenant managed hosting services.
The document discusses cloud computing, which uses internet and remote servers to store and access data and applications from anywhere. There are three cloud service models: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). There are also four cloud deployment models: private cloud for a particular organization, community cloud for shared requirements, public cloud open for public use, and hybrid cloud combining multiple models. Cloud computing allows efficient computation through centralized resources and inexpensive, managed hosting without additional hardware costs or installations. However, data is reliant on trusted third parties and may be difficult to move elsewhere.
The convergence of mobile computing, cloud utilization, BYOD, and collaboration – among the fastest growing trends in computing today – has led to complexity in securing multiple systems, applications, platforms and devices. The difficulty in patching together an integrated security protocol to cover such a disparate and disperse computing environment is leaving many organizations vulnerable. For example, nearly half of companies that permit employees to use their own devices at work (a practice known as “BYOD”) reported experiencing a data or security breach as a result of an employee-owned device accessing the corporate network. And yet, 87% of executives say their employees are using personal devices for work-related purposes.
A SECURITY FRAMEWORK IN CLOUD COMPUTING INFRASTRUCTUREIJNSA Journal
In a typical cloud computing diverse facilitating components like hardware, software, firmware,
networking, and services integrate to offer different computational facilities, while Internet or a private
network (or VPN) provides the required backbone to deliver the services. The security risks to the cloud
system delimit the benefits of cloud computing like “on-demand, customized resource availability and
performance management”. It is understood that current IT and enterprise security solutions are not
adequate to address the cloud security issues. This paper explores the challenges and issues of security
concerns of cloud computing through different standard and novel solutions. We propose analysis and
architecture for incorporating different security schemes, techniques and protocols for cloud computing,
particularly in Infrastructure-as-a-Service (IaaS) and Platform-as-a-Service (PaaS) systems. The proposed
architecture is generic in nature, not dependent on the type of cloud deployment, application agnostic and
is not coupled with the underlying backbone. This would facilitate to manage the cloud system more
effectively and provide the administrator to include the specific solution to counter the threat. We have also
shown using experimental data how a cloud service provider can estimate the charging based on the
security service it provides and security-related cost-benefit analysis can be estimated.
Lee Newcombe, Capgemini “Security threats associated with cloud computing”Chris Purrington
This document discusses the security threats associated with cloud computing. It identifies several types of threats including threats from cloud service provider staff, competitors in a multi-tenant environment, hackers targeting the new cloud environment, insiders with easy access to cloud services, and availability issues if the cloud provider has an outage. However, it also notes that many of the threats are similar to those in traditional outsourcing and the risks can be managed.
This document provides an overview of cloud computing, including its structure, categories, architecture, storage, security, and deployment models. It defines cloud computing as relying on sharing hardware and software resources over a network rather than local devices. The cloud computing architecture has a front end that users interact with and a back end comprising various computers, servers, and storage devices that make up "the cloud." It also discusses cloud storage architecture, reference models, and ensuring security for data in transit, at rest, and through authentication and access control.
Cloud security refers to securing the many aspects of cloud computing, including maintaining data security within the cloud, between users and the cloud, and protecting cloud infrastructure. There are different types of clouds - public clouds allow remote access but data is held by third parties; private clouds keep data behind a corporate firewall; hybrid clouds combine public and private access; and community clouds share resources between organizations. Each cloud type has its own security risks and requirements due to factors like data access and control.

Protecting Dynamic Datacenters From the Latest Threatswhite paper
The document discusses the challenges of securing dynamic datacenters, where servers are increasingly virtualized, mobile between physical locations, and deployed in public clouds. It notes that traditional network-based security is insufficient as servers lose their strict separation. The proliferation of virtual machines multiplies security risks like exposure to attacks between VMs and loss of security context during live migration. Cloud computing further challenges the security model by removing even the datacenter perimeter and requiring host-based protections on internet-accessible VMs. The document introduces Third Brigade Deep Security as a comprehensive server and application protection solution suited for dynamic virtual, cloud and traditional datacenter environments.
A Multi-Level Security for Preventing DDOS Attacks in Cloud Environmentsmlaij
This document discusses security challenges in cloud computing environments, including distributed denial of service (DDoS) attacks. It describes various types of DDoS attacks such as flooding requests and botnets attacks. Existing prevention methods are discussed, such as filter-based solutions and client puzzle protocols that require clients to solve cryptographic puzzles before connecting. The proposed system aims to prevent DDoS attacks before they occur using puzzle technology to identify whether requests come from users or robots. It seeks to address issues with detection-based approaches that require continuous monitoring and take time to stop attacks.

This is a literature survey about security issues and countermeasures on cloud computing. This paper discusses about an overview of cloud computing and security issues of cloud computing.
Cloud computing is set of resources and services offered through the Internet. Cloud
services are delivered from data centers located throughout the world. Cloud computing
facilitates its consumers by providing virtual resources via internet. The biggest challenge in
cloud computing is the security and privacy problems caused by its multi-tenancy nature and the
outsourcing of infrastructure, sensitive data and critical applications. Enterprises are rapidly adopting
cloud services for their businesses, measures need to be developed so that organizations can be assured
of security in their businesses and can choose a suitable vendor for their computing needs. 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. In this paper we identify the most vulnerable security
threats/attacks in cloud computing, which will enable both end users and vendors to know a bout
the k ey security threats associated with cloud computing and propose relevant solution directives to
strengthen security in the Cloud environment. We also propose secure cloud architecture for
organizations to strengthen the security.

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.

Migration of Virtual Machine to improve the Security in Cloud Computing IJECEIAES
Cloud services help individuals and organization to use data that are managed by third parties or another person at remote locations. With the increase in the development of cloud computing environment, the security has become the major concern that has been raised more consistently in order to move data and applications to the cloud as individuals do not trust the third party cloud computing providers with their private and most sensitive data and information. This paper presents, the migration of virtual machine to improve the security in cloud computing. Virtual machine (VM) is an emulation of a particular computer system. In cloud computing, virtual machine migration is a useful tool for migrating operating system instances across multiple physical machines. It is used to load balancing, fault management, low-level system maintenance and reduce energy consumption. Virtual machine (VM) migration is a powerful management technique that gives data center operators the ability to adapt the placement of VMs in order to better satisfy performance objectives, improve resource utilization and communication locality, achieve fault tolerance, reduce energy consumption, and facilitate system maintenance activities. In the migration based security approach, proposed the placement of VMs can make enormous difference in terms of security levels. On the bases of survivability analysis of VMs and Discrete Time Markov Chain (DTMC) analysis, we design an algorithm that generates a secure placement arrangement that the guest VMs can moves before succeeds the attack.
Secure Virtualization for Cloud Environment Using Guest OS and VMM-based Tech...ijcncs
This document summarizes a research paper on secure virtualization for cloud environments. The paper proposes a two-tier security architecture that uses multiple working modes for security components at the guest level to decrease overhead from security processes. It also includes a security supervisor at the hypervisor layer to avoid false security alarms. The paper discusses security issues in virtualized cloud environments like access control vulnerabilities, DOS attacks, vulnerabilities in the virtualization platform and security management. It proposes solutions like access control policies, load balancing during attacks, secure administrative zones, and additional security mechanisms like firewalls and intrusion detection to address these issues.
This document discusses defense-in-depth strategies for securing databases in cloud environments. It describes how databases continue to be attractive targets for attackers due to the sensitive data they store. It then discusses how the hybrid cloud model raises new security concerns around data access and control. The document proposes a strategy of always-on encryption, centralized key management with Oracle Key Vault, configuration compliance monitoring, and restricting access to sensitive data with Oracle Database Vault to provide consistent security across on-premises and cloud databases.
This document discusses security issues and challenges related to data security in cloud computing. It begins by providing background on cloud computing and its benefits. It then discusses some key security challenges including data breaches, insecure interfaces, denial of service attacks, eavesdropping, data loss, lack of compatibility between cloud services, abuse of cloud technologies, insufficient user understanding of risks, and safe storage of encryption keys. It also discusses issues regarding data integrity verification and privacy when data is outsourced to cloud servers. In the end, it recommends solutions such as homomorphic encryption, decentralized information flow control, and data accountability frameworks to enhance security in cloud computing.
This document discusses three methods of software assurance: kernel separation, desktop virtualization, and the Trusted Platform Module (TPM).
Kernel separation (also known as MILS) isolates operating system processes and partitions hardware to separate developer code, system resources, and data objects. This aims to reduce vulnerabilities by compartmentalizing different functions.
Desktop virtualization stores the desktop environment on centralized servers rather than individual devices. This allows for easier maintenance, troubleshooting, and access controls. All user data and customizations can be removed when logging off.
TPMs create encryption keys during the boot process to validate that critical software and firmware have not been modified. This helps detect malware early and takes a proactive approach to
This document discusses security issues related to cloud computing. It begins with an introduction to cloud computing models including Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). It then discusses potential security threats in cloud computing like denial of service attacks, side channel attacks, and man-in-the-middle cryptographic attacks. The document proposes a layered framework for assured cloud computing and techniques for secure publication of data in the cloud, including encryption. It concludes that achieving end-to-end security in cloud computing will be challenging due to complexity, but that more secure operations can be ensured even if some parts of the cloud fail.

Discussion 1Cloud computing offers the ability to share informatVinaOconner450
Discussion 1
Cloud computing offers the ability to share information and facilities belonging to multiple organizations or sites. Hence, expanding the use of cloud computing causes security challenges for us. NIST defines cloud computing as the representation for making relevant, on-demand adjustments for the right of entry into a collective pool. With fewer supervisory practices or cloud supplier contact, all of these networks, servers, storage, software and services are constantly designed.
Until now, cloud computing has been viewed as a revolutionary measuring concept. This required the use of more than one stage of thinking to quantify contact. The spot specifications of these providers are sold at cheaper rates online. The inference of high flexibility and usability is the reason. Cloud computing is the biggest subject that is starting to get the right kind of attention lately. The rewards of cloud computing platforms arise from financial networks of all types.
Cloud computing, is an evolving method of distributed computing that is still in its inception. The theory uses all levels of explanations and interpretation on its own. The main one that has connectivity and other calculative possessions is a public cloud. This is made accessible digitally to average citizens and is known to all the cloud service companies. The confidential cloud on the other side is the one in which the calculating atmosphere is fully created for the industry. This can be done by the sector or by third parties. This can be hosted in the knowledge hub of the industry. The private cloud gives the industry good leverage of the means of communication and computation relative to the public cloud. The hybrid cloud is primarily the fusion of two or more than two clouds, this becomes the unusual entities that are connected to each other by integrated or standardized technologies that facilitate interconnectivity.
Today, in certain ways, the focus is on vendors to detect and prevent cloud events. The more autonomy we have, the more flexibility we have in incorporating virtual appliances and resources for network security and the more we will be able to detect unusual incidents and take actions immediately.

In cloud computing, there is a comfort of sharing distributed services and resources belonging to different sites or organization which help companies to manage their business operation globally and help it to expand their organization at a large scale. However, it also brings complexity to the incident handlers as firstly as many users can access the same information freely, there will be substrata of users who will not be paying for the resources and identifying those users is a challenge. Second, as there are numerous security parameters in cloud computing in terms of networks, databases, resource scheduling, and memory mana ...

People being "adaptable to change" is different than not "questioning change" because questioning change allows for risk assessments and responses to innovations through collaboration and engagement. While motivations and inspirations can lead to success, understanding and responding to risks is important before implementing innovations to avoid destroying what is cherished or desired to be protected. Questioning change through identifying, analyzing, and mitigating risks is necessary for true collaboration around innovation.
The document discusses the need for individuals to look inward and make positive changes within themselves in order to achieve sustainability. This includes controlling negative thoughts, participating in different cultures, modeling good behavior, and caring for children to create a better future.
My computer was hijacked by spyware that was copying emails and documents, mapping files in an .ini file, and running JavaScript to locate information. I stopped the script and changed access and file settings to prevent further monitoring and transfer of files, though the spying may have been occurring for some time. Uninstalling the SoftGrid Client may not remove all related files and could damage other programs, so care needs to be taken in removal.

Storage infrastructures. And “The Cloud” has a great capacity for transporting
terabytes of data at very fast speed.
The risks are dependent on the security risks’ assessment, mitigation, and

“Data in storage” of the Cloud environments are more “Vulnerable to Attacks.”

“The most significant challenge is security…Highly sensitive applications
related to critical infrastructure management, health-care applications and others
will most likely be hosted by private clouds … The Software as a Service
(SaaS) model faces similar challenges as other online services required to
protect private information, such as financial or health-care services … Still,
such services are vulnerable to DoS attacks and malicious insiders.
Data in storage is most vulnerable to attack, so devote special attention
to protecting storage servers. The data replication necessary to ensure continuity
of service in case of storage system failure increases vulnerability. Data
encryption may protect data in storage, but eventually data must be decrypted for
processing. Then it’s exposed to attack … The Infrastructure as a Service
(IaaS) model is by far the most challenging to defend against attacks. Indeed,
an IaaS user has much more freedom than the other two cloud delivery models.
An additional source of concern is that the considerable cloud resources could be
used to initiate attacks against the network and the computing infrastructure …
Virtualization is a critical design option for this model, but it exposes
the system to new sources of attack. The trusted computing base (TCB) of a
virtual environment includes not only the hardware and the hypervisor but also
the management OS. You can save the entire state of a virtual machine (VM)
to a file to allow migration and recovery … Yet this possibility challenges
the strategies to bring the servers belonging to an organization to a
