...Problem Statement Discussion and Justification Cloud users face security threats both from outside and inside the cloud. Many of the security issues involved in protecting clouds from outside threats are similar to those already facing large data centers. In the cloud, however, this responsibility is divided among potentially many parties, including the cloud user, the cloud vendor, and any third-party vendors that users rely on for security-sensitive software or configurations. The cloud user is responsible for application-level security. The cloud provider is responsible for physical security, and likely for enforcing external firewall policies. Security for intermediate layers of the software stack is shared between the user and the operator; the lower the level of abstraction exposed to the user, the more responsibility goes with it. While cloud computing may make external-facing security easier, it does pose the new problem of internal-facing security. Cloud providers must guard against theft or denial-of-service attacks by users. Users need to be protected from one another. The primary security mechanism in today's clouds is virtualization. It is a powerful defense, and protects against most attempts by users to attack one another or the underlying cloud infrastructure. However, not all resources are virtualized and not all virtualization environments are bug-free. Virtualization software has been known to contain bugs that allow virtualized code to "break loose" to some...

...threat landscape is fundamentally different with the proliferation of mobile, web and cloud based applications supported by third parties. The need for third party software security is so essential that a group of security leaders from the highly competitive financial services sector established a working group through the Financial Services Information Sharing and Analysis Center (FS-ISAC) to provide guidance for the rest of the industry on additive controls to address software security. Though the goal of this working group is to help improve security at financial organizations, enterprises of all kinds can and should adopt this new guidance to address the increasing danger posed by third party applications. Every industry uses third party software to increase employee productivity, deliver the latest technology to their customers and maintain relevancy in evolving markets. In the financial services industry, this has manifested with mobile payments, hip web interfaces, and banks going social, just to name a few. Financial services has long worked to apply effective controls and protect the sensitive data flowing through these slick applications through the Financial Services Roundtable (BITS) or FS-ISAC. Though there are established controls for protecting information from software vulnerabilities of third party service and software providers, what is not established is how to ensure secure software development practices are applied by those third parties that develop software...

...Cloud Security Planning Abstract Cloud systems as new online storage and computing systems provide great potentials to all businesses and organizations of creating new approach of storage and computing; cloud system guarantee that all your files and valuable data can be accessed and recovered from anywhere in the world, providing a new meaning of technology. Unfortunately and as to what happen with all emerging technologies there are new threats, risks, breaches, and problems arise with such technologies. They are considered challenges that vary from configuration problems to security breaches to harmful attacks; which may cost the company large losses and in some time financial disasters. In this case study we will try to identify the major threats that may affect the cloud security negatively which can be divided into three major categories: 1. Attackers and threats: where the attacks are no longer limited by breaching the data on someone’s personal computer. It became larger wider and involves more organized crimes. 2. Developed Structure technologies: the amount of data and information used today provides great challenges to system engineers and security designers to visualize and utilize their system to isolate and protect the data on them. 3. Regularity environment challenges: Most companies and IT departments are facing great challenges to meet the laws, legal requirements and consistency acquiescence especially with growth of demand on cloud systems. ...

...Cloud Computing and Information Security Krystal Hagi Daytona State College Student Khagi1@yahoo.com Abstract In order to discuss the security of information in cloud computing, we must first cover what is Cloud Computing. There are many types of cloud computing services, such as, SaaS, PaaS, IaaS, public clouds, private clouds, and hybrid clouds Examples. They all work similarly but have not only different tools, but varying levels of security for various needs. These differing types of clouds and networks as a service offer off site data storage in a secured location, which in essence frees up space and virtual infrastructure for personal and/or business networks, and devices. There are advantages and disadvantages to cloud computing, just like any other product or service. The advantages being, storage for data, accessibility from virtually anywhere there is a network connection, automated management, security, apps, tools, etc. The disadvantages include monthly costs for space on the offsite network, security, involvement of a third party, no access to the physical structure - which means if the cloud server goes down, your data may not be accessible, etc. There is one instance with cloud computing that is both an advantage and a disadvantage, and that is the security. While a cloud may be more secure than your own network How?, personal or business, using cloud services puts the security out of your hands in both the physical and logical sense. Using a cloud, means the...

...Security Considerations for Cloud Computing Carlos Chandler Abstract Cloud computing is an emerging Information Technology (IT) model whereby a company utilizes a pay-per-use service for it computing needs rather than maintain a local data center run by its in-house IT department. By treating computing resources as a commodity or operating expense, it allows firms to focus less on IT and more on the core elements of the operations strategy. Because of advantages like this, its popularity has grown exponentially in recent years. However, cloud computing also has certain inherent risks in its present form. This paper seeks to understand the key advantages driving businesses to adopt this computing model in ever increasing numbers, while at the same time understanding what risks they are taking in doing so. To gain insight into these risks, this paper incorporates statistical research into what experts in the field believe to be the greatest down-sides to converting to this increasingly common IT model. Security Considerations for Cloud Computing What is Cloud Computing, Anyway? To begin, let us illustrate what cloud computing is. Imagine you run a cookie baking business that takes orders from around the country via an online store. To handle the orders, would your business buy a fleet of trucks and deliver its own shipments, or would you simply contract with UPS or FedEx to ship the orders on your behalf? Clearly the cost efficiencies in contracting the shipping...

...Proceedings of the 44th Hawaii International Conference on System Sciences - 2011 Cloud Hooks: Security and Privacy Issues in Cloud Computing Wayne A. Jansen, NIST Abstract In meteorology, the most destructive extratropical cyclones evolve with the formation of a bent-back front and cloud head separated from the main polar-front, creating a hook that completely encircles a pocket of warm air with colder air. The most damaging winds occur near the tip of the hook. The cloud hook formation provides a useful analogy for cloud computing, in which the most acute obstacles with outsourced services (i.e., the cloud hook) are security and privacy issues. This paper identifies key issues, which are believed to have long-term significance in cloud computing security and privacy, based on documented problems and exhibited weaknesses. • applications can be developed upon and deployed. It can reduce the cost and complexity of buying, housing, and managing hardware and software components of the platform. Infrastructure-as-a-Service (IaaS) enables a software deployment model in which the basic computing infrastructure of servers, software, and network equipment is provided as an on-demand service upon which a platform to develop and execute applications can be founded. It can be used to avoid buying, housing, and managing the basic hardware and software infrastructure components. 1.

...Concept of cloud computing was started in 2000s. Once this was introduced it has created a new business model and platform for many online business and technologies. To store any kind of data local servers will be used. But in today’s world with internet, the practice of using servers and networks on internet for storing, processing and managing any kind of data online is the concept of cloud computing (Margaret Rouse, 2015). Through this, both its platform and type of applications can be described, cloud computing provides its services in several layers to its users. By using this technology and internet applications can be run based on large data centers and servers. Cloud computing has gone through number of several phases including grid and utility computing (Margaret Rouse, 2015). Many enterprises have already started to implement cloud computing by knowing the potential of this technology. In 2012 according to IDG reports, (IDG ENTERPRISE MARKETING, 2016) the usage of cloud computing was 12% and by 2014 the number increased to 69% with the humongous change. The main reasons for many of enterprises to adopt to this technology was its cost and the flexibility to run any application faster than by the traditional method. Few features in could computing and its business functions like data analytics, data and storage management content management, conferencing solutions and collaborations. By 2015, 24% of enterprises used cloud computing for standardizing their IT budgets...

...Cloud Computing and Security ITM 5600 Thomas Payne Webster University Cloud Computing and Security The National Institute of Standards and Technology (NIST) define cloud computing this way. “Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. This cloud model promotes availability and is composed of five essential characteristics (On-demand self-service, Broad network access, Resource pooling, Rapid elasticity, Measured Service); three service models (Cloud Software as a Service (SaaS), Cloud Platform as a Service (PaaS), Cloud Infrastructure as a Service (IaaS)); and, four deployment models (Private cloud, Community cloud, Public cloud, Hybrid cloud). Key enabling technologies include: (1) fast wide-area networks, (2) powerful, inexpensive server computers, and (3) high-performance virtualization for commodity hardware” (National Institue of Standards and Technology, 2011). There is a lot to take in from that lengthy definition. This may explain why there is so much ambiguity and “hand wringing” surrounding cloud computing. Major companies and government alike have started to embrace cloud services and architecture. This hasn’t been an easy transition, however many higher level managers are not aware or just not informed on...

...Cloud computing: benefits, risks and recommendations for information security Cloud computing is a new way of delivering computing resources, not a new technology. Computing services ranging from data storage and processing to software, such as email handling, are now available instantly, commitment-free and on-demand. Since we are in a time of belt-tightening, this new economic model for computing has found fertile ground and is seeing massive global investment. According to IDC’s analysis, the worldwide forecast for cloud services in 2009 will be in the order of $17.4bn1. The estimation for 2013 amounts to $44.2bn, with the European market ranging from €971m in 2008 to €6,005m in 2013 2. The key conclusion of ENISA’s 2009 paper on Cloud Computing: benefits, risks and recommendations for information security3 is that the cloud’s economies of scale and flexibility are both a friend and a foe from a security point of view. The massive concentrations of resources and data present a more attractive target to attackers, but cloud-based defences can be more robust, scalable and cost-effective. ENISA’s paper allows an informed assessment of the security risks and benefits of using cloud computing - providing security guidance for potential and existing users of cloud computing. The new economic model has also driven technical change in terms of: Scale: commoditisation and the drive towards economic efficiency have led to massive concentrations of the hardware resources required to provide...
