However, both of them may use multi-tenant architecture so multiple concurrent users utilize the same software. The selection criteria through which we evaluated study sources was based on the research experience of the authors of this work, and in order to select these sources we have considered certain constraints: studies included in the selected sources must be written in English and these sources must be web-available. The most secure way is to hook each VM with its host by using dedicated physical channels. Townsend M: Managing a security program in a cloud computing environment. 2010.

Security web services standards describe how to secure communication between applications through integrity, confidentiality, authentication and authorization. Unfortunately, integrating security into these solutions is often perceived as making them more rigid [4]. Seminar on Network Security; 2007. . These applications are typically delivered via the Internet through a Web browser [12, 22]. They implemented a prototype system based on Xen hypervisors using stateful firewall technologies and userspace tools such as iptables, xm commands program and conntrack-tools. For example, Amazon offers a public image repository where legitimate users can download or upload a VM image. In both SaaS and PaaS, data is associated with an application running in the cloud. 10.1007/s13174-010-0007-6. In Proceedings of the 40th annual Hawaii International conference on system sciences.

Security concerns relate to risk areas such as external data storage, dependency on the “public” internet, lack of control, multi-tenancy and integration with internal security. 116: 116; 2009:109–116. In Proceedings of the 3rd ACM workshop on Cloud Computing Security workshop. This model has drawbacks, but security issues are not so bad compared with the other models. IaaS, or Infrastructure-as-a-Service, is the traditional cloud model provided by, e.g., Amazon AWS.Essentially, the cloud service provider offers virtual machines, containers, and/or serverless computing services. Most developers still deal with application security issues in isolation, without understanding the security of the ""full stack"". Security controls in Cloud Computing are, for the most part, no different than security controls in any IT environment. Cloud Computing leverages many existing technologies such as web services, web browsers, and virtualization, which contributes to the evolution of cloud environments. The PaaS provider secures the operating system and physical infrastructure. The question focus was to identify the most relevant issues in Cloud Computing which consider vulnerabilities, threats, risks, requirements and solutions of security for Cloud Computing. Countermeasures are proposed and discussed. Like Table 2 it also describes the threats that are related to the technology used in cloud environments, and it indicates what cloud service models are exposed to these threats.

Thus, PaaS models also inherit security issues related to mashups such as data and network security [39]. In Proceedings of the 2009 conference on Hot topics in cloud computing, San Diego, California. Hashizume K, Yoshioka N, Fernandez EB: Three misuse patterns for Cloud Computing. A strong and effective authentication framework is essential to ensure that individual users can be correctly identified without the authentication system succumbing to the numerous possible attacks. There are also other web application security tools such as web application firewall. A study by Gartner [1] considered Cloud Computing as the first among the top 10 most important technologies and with a better prospect in successive years by companies and organizations. In Security engineering for Cloud Computing: approaches and Tools. There are more security issues, but it is a good start for securing web applications. 3 0 obj Also, PaaS users have to depend on both the security of web-hosted development tools and third-party services. In Proceedings of the Joint ERCIM Workshop on Software Evolution (EVOL) and International Workshop on Principles of Software Evolution (IWPSE), Antwerp, Belgium. We therefore established that the studies must contain issues and topics which consider security on Cloud Computing, and that these studies must describe threats, vulnerabilities, countermeasures, and risks. Syst. Virtual Networks increase the VMs interconnectivity, an important security challenge in Cloud Computing [51]. OWASP: The Ten most critical Web application Security risks. Resolving such problems may increase the usage of cloud thereby reducing the amount spent for resources. With SaaS, the burden of security lies with the cloud provider. Therefore, any vulnerability associated to these technologies also affects the cloud, and it can even have a significant impact. Available: http://www.enisa.europa.eu/activities/risk-management/files/deliverables/cloud-computing-risk-assessment Available: Dahbur K, Mohammad B, Tarakji AB: A survey of risks, threats and vulnerabilities in Cloud Computing. Enumerating these security issues was not enough; that is why we made a relationship between threats and vulnerabilities, so we can identify what vulnerabilities contribute to the execution of these threats and make the system more robust. This technique consists in first breaking down sensitive data into insignificant fragments, so any fragment does not have any significant information by itself. Providers of Platform as a Service (PaaS) and Infrastructure as a Service (IaaS) face a common set of challenges that must be overcome to ensure successful service delivery and encourage adoption. Washington, DC, USA: IEEE Computer Society; 2011:1–10. These relationships and dependencies between cloud models may also be a source of security risks. - Provides convenience for users in accessing different OSs (as opposed to systems with multiple boot capability). Also, even when virtual machines are offline, they can be vulnerable [24]; that is, a virtual machine can be instantiated using an image that may contain malicious code. Once again, security cannot be … Later, the experts will refine the results and will include important works that had not been recovered in these sources and will update these work taking into account other constraints such as impact factor, received cites, important journals, renowned authors, etc. Apocryphal accounts can let attackers perform any malicious activity without being identified [16]. We put more emphasis on threats that are associated with data being stored and processed remotely, sharing resources and the usage of virtualization. An examination of PaaS security challenges Organizations need to consider the security implications associated with data location, privileged access and a distributed architecture in the PaaS model. Before analyzing security challenges in Cloud Computing, we need to understand the relationships and dependencies between these cloud service models [4]. As a result, security is sometimes inconsistent, and can be seen as a barrier to moving applications to the cloud. Keeping the VMM as simple and small as possible reduces the risk of security vulnerabilities, since it will be easier to find and fix any vulnerability. 10.1016/j.jnca.2010.07.006. Moreover, virtualization introduces the ability to migrate virtual machines between physical servers for fault tolerance, load balancing or maintenance [16, 46]. As a result, security is sometimes inconsistent, and can be … Network components are shared by different tenants due to resource pooling. In the world of SaaS, the process of compliance is complex because data is located in the provider’s datacenters, which may introduce regulatory compliance issues such as data privacy, segregation, and security, that must be enforced by the provider. SaaS users have less control over security among the three fundamental delivery models in the cloud. Security Implications: PaaS PaaS: Virtual Environments - Provides dynamic load balancing capacity across multiple file systems and machines. In Cloud Computing: principles, systems & applications. Jordan: Amman; 2011:1–6. Here are some of the security issues associated to IaaS. As described in this paper, storage, virtualization, and networks are the biggest security concerns in Cloud Computing. endobj The authors conducted some experiments to evaluate their framework, and the results revealed that the security policies are in place throughout live migration. The cloud model provides three types of services [21, 28, 29]: Software as a Service (SaaS). [66] presents an algorithm to create dynamic credentials for mobile cloud computing systems.

In the third maturity model multi-tenancy is added, so a single instance serves all customers [34]. Harnik D, Pinkas B, Shulman-Peleg A: Side channels in Cloud services: deduplication in Cloud Storage. However, because of the cloud service models employed, the operational models, and the technologies used to enable cloud services, Cloud Computing may present different risks to an organization than traditional IT solutions. In PaaS, developers do not usually have access to the underlying layers, so providers are responsible for securing the underlying infrastructure as well as the applications services [40]. Privileged users such as cloud administrators usually have unlimited access to the cloud data. IEEE Security Privacy 2010, 8(6):40–47. Winkler V: Securing the Cloud: Cloud computer Security techniques and tactics. Unlike physical servers, VMs have two boundaries: physical and virtual [24]. Encryption techniques can be used to secure data while it is being transferred in and out of the cloud or stored in the provider’s premises. The capability provided to the consumer is to deploy onto the cloud infrastructure his own applications without installing any platform or tools on their local machines. This work was supported in part by the NSF (grants OISE-0730065). Mather T, Kumaraswamy S, Latif S: Cloud Security and Privacy. PubMed Google Scholar.

Although there are many benefits to adopting Cloud Computing, there are also some significant barriers to adoption. Mell P, Grance T: The NIST definition of Cloud Computing. Malware injections are scripts of malicious code that hackers inject into a cloud computing service. The adoption of SaaS applications may raise some security concerns. In [70], they propose a method based on the application of fully homomorphic encryption to the security of clouds.

Cloud Computing combines a number of computing concepts and technologies such as Service Oriented Architecture (SOA), Web 2.0, virtualization and other technologies with reliance on the Internet, providing common business applications online through web browsers to satisfy the computing needs of users, while their software and data are stored on the servers [5]. Security challenges in SaaS applications are not different from any web application technology, but traditional security solutions do not effectively protect it from attacks, so new approaches are necessary [21]. In the second model, the vendor also provides different instances of the applications for each customer, but all instances use the same application code. Besides secure development techniques, developers need to be educated about data legal issues as well, so that data is not stored in inappropriate locations. Cite this article. Moreover, [69] describes that encryption can be used to stop side channel attacks on cloud storage de-duplication, but it may lead to offline dictionary attacks reveling personal keys. on Availability, Reliability, and Security (ARES 2009), Fukuoka, Japan. NY, USA: ACM New York; 2010:88–92. Virtual machine security becomes as important as physical machine security, and any flaw in either one may affect the other [19]. [Online].

Accessed: 15-Jul-2011. However, the underlying compute, network, and storage infrastructure is controlled by cloud providers. Fong E, Okun V: Web application scanners: definitions and functions. Certain security issues exist which prevents individuals and industries from using clouds despite its advantages. In the cloud, security is a shared responsibility between the cloud provider and the customer. Kitchenham B, Charters S: Guidelines for performing systematic literature reviews in software engineering. This approach enables more efficient use of the resources but scalability is limited. Additionally, it is important to understand the lifecycle of the VMs and their changes in states as they move through the environment. During this phase, the search in the defined sources must be executed and the obtained studies must be evaluated according to the established criteria.

The prototype of the system was implemented based on Xen and GNU Linux, and the results of the evaluation showed that this scheme only adds slight downtime and migration time due to encryption and decryption. Furthermore, virtual machines are able to be rolled back to their previous states if an error happens. TVDc provides isolation between workloads by enforcing mandatory access control, hypervisor-based isolation, and protected communication channels such as VLANs. x��=�r㶒�S5��G�Ԙ&�$S��N�Lv�M2���Crh�c3�H^��9s��/��� ��e'E"��F������m�W�6�����m[�n��Ӌ��?O/>�֧��fS��v��W��ߜ%__�|q��%eZ�����,��_�*e�L�\��|�fߝ�����,��_�����,�.�b�����m��Z����.O���:�~y�/���n�m��{��,O����G�A6�z�4�������,[\%竦��K-�K���@�ǎ�_���\�3����oa�f�|:J�T��p� @��#Z�Ea�����:�taO5���������X[����۾B>3~"��4q�BqO�OŨ-���S�5��L$+�-�@�Tj�����c�����S��4q��dK'�ГN*ֶ:��rq��n��lz��`c�h'�N:���o��N���Cãh�N����%R�4�-N��9L�O_D' Pittsburgh, PA: CMU-CS-01–120; 2001.

Manage cookies/Do not sell my data we use in the preference centre. Because Cloud Computing represents a relatively new computing model, there is a great deal of uncertainty about how security at all levels (e.g., network, host, application, and data levels) can be achieved and how applications security is moved to Cloud Computing [9].

Traditional security mechanisms such as identity, authentication, and authorization are no longer enough for clouds in their current form [11]. IaaS essentially refers to purchasing the basic storage, processing power and networking to support the delivery of cloud computing applications. Data may be stored on different places with different legal regimes that can compromise its privacy and security. Virtualized environments are vulnerable to all types of attacks for normal infrastructures; however, security is a greater challenge as virtualization adds more points of entry and more interconnection complexity [45]. Cloud Security Alliance: Security guidance for critical areas of Mobile Computing. Future Internet 2012, 4(2):430–450. We will discuss three models of cloud-based computing: public, private, and hybrid. However, flaws in web applications may create vulnerabilities for the SaaS applications. IEEE Computer Society Washington DC, USA; 2010:344–349. volume 4, Article number: 5 (2013) DC, USA: IEEE Computer Society Washington; 2010:18–21. For instance, most virtualization platforms such as Xen provide two ways to configure virtual networks: bridged and routed, but these techniques increase the possibility to perform some attacks such as sniffing and spoofing virtual network [45, 52]. As mentioned before, sharing resources allows attackers to launch cross-tenant attacks [20]. Same as SaaS, PaaS also brings data security issues and other challenges that are described as follows: Moreover, PaaS does not only provide traditional programming languages, but also does it offer third-party web services components such as mashups [10, 38]. Computer 2009, 42(8):106–108. In [49], the authors propose a virtual machine image management system in a cloud computing environments. The capability provided to the consumer is to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications. In part, this is because of the degree of abstraction, the SaaS model is based on a high degree of integrated functionality with minimal customer control or extensibility. Furthermore, we describe the relationship between these vulnerabilities and threats; how these vulnerabilities can be exploited in order to perform an attack, and also present some countermeasures related to these threats which try to solve or improve the identified problems.

Security of PaaS clouds is considered from multiple perspectives including access control, privacy and service continuity while protecting both the service provider and the user. Cloud Computing leverages many technologies (SOA, virtualization, Web 2.0); it also inherits their security issues, which we discuss here, identifying the main vulnerabilities in this kind of systems and the most important threats found in the literature related to Cloud Computing and its environment as well as to identify and relate vulnerabilities and threats with possible solutions. Unlike traditional client-based software development using tools such as Microsoft Visual Studio , PaaS offers a shared development environment, so authentication, access control, and authorization mechanisms must combine to ensure that customers are kept completely separate from each other.

The Open Web Application Security Project (OWASP) has identified the ten most critical web applications security threats [32]. Using covert channels, two VMs can communicate bypassing all the rules defined by the security module of the VMM [48]. 13, V13–39. A SaaS provider may rent a development environment from a PaaS provider, which might also rent an infrastructure from an IaaS provider. In Proceedings of the 2012 ACM conference on Computer and communications security, New York, NY, USA. Even at this early stage in cloud adoption, users of PaaS services are raising the question of the portability of their applications-- not to a given PaaS provider, but from that first provider to a different one, or even back to the data center. 10.1145/1743546.1743565. Some confidential information such as passwords or cryptographic keys can be recorded while an image is being created. Introduction Cloud computing is the delivery of computing as a service rather than a product, whereby shared resources, software, and information are provided to computers and other devices as a utility (like the electricity grid) over a network (typically Therefore, the research question addressed by our research was the following: What security vulnerabilities and threats are the most important in Cloud Computing which have to be studied in depth with the purpose of handling them? Viega J: Cloud Computing and the common Man. Largely because of the relatively lower degree of abstraction, IaaS offers greater tenant or customer control over security than do PaaS or SaaS [10]. The Virtual Machine Monitor (VMM) or hypervisor is responsible for virtual machines isolation; therefore, if the VMM is compromised, its virtual machines may potentially be compromised as well. The three basic operations for cloud data are transfer, store, and process. In Proceedings of the IEEE symposium on Security and privacy.

Fully homomorphic encryption allows performing arbitrary computation on ciphertexts without being decrypted. Ristenpart T, Tromer E, Shacham H, Savage S: Hey, you, get off of my cloud: exploring information leakage in third-party compute clouds. endobj Next, in Section 3 we define in depth the most important security aspects for each layer of the Cloud model. The inclusion and exclusion criteria of this study were based on the research question. Gaithersburg, MD: NIST, Special Publication 800–144; 2011. However, we have to take into account that PaaS offers a platform to build and deploy SaaS applications, which increases the security dependency between them. Security problems of PaaS clouds are explored and classified. A security checklist for SaaS, PaaS and IaaS cloud models Key security issues can vary depending on the cloud model you're using. Somani U, Lakhani K, Mundra M: Implementing digital signature with RSA encryption algorithm to enhance the data Security of Cloud in Cloud Computing. There are some surveys where they focus on one service model, or they focus on listing cloud security issues in general without distinguishing among vulnerabilities and threats. Since Cloud Computing leverages many technologies, it also inherits their security issues. Journal in Computer Virology Springer 2012, 8: 85–97. They claimed that RSA is the most recognizable algorithm, and it can be used to protect data in cloud environments.

Web application firewall routes all web traffic through the web application firewall which inspects specific threats. [Online]. If the image is not “cleaned”, this sensitive information can be exposed to other users. This presentation will help you architecturally understand each of the service models -- Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS), and Software-as-a-Service (SaaS) -- and the security risks you can expect with each, as well as how IaaS, PaaS and SaaS security issues and risks affect not only data security but also organizational compliance efforts. 2010.
