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. endobj <>>> The inclusion and exclusion criteria of this study were based on the research question. Dawoud W, Takouna I, Meinel C: Infrastructure as a service security: Challenges and solutions. In IEEE youth conference on information Computing and telecommunications (YC-ICT). In [70], they propose a method based on the application of fully homomorphic encryption to the security of clouds. We have carried out a systematic review [13–15] of the existing literature regarding security in Cloud Computing, not only in order to summarize the existing vulnerabilities and threats concerning this topic but also to identify and analyze the current state and the most important security issues for Cloud Computing. Cloud Computing is a flexible, cost-effective, and proven delivery platform for providing business or consumer IT services over the Internet. Virtual machine security becomes as important as physical machine security, and any flaw in either one may affect the other [19]. NY, USA: ACM New York; 2012:305–316. SaaS cloud security issues are naturally centered around data and access because most shared security responsibility models leave those two as the sole responsibility for SaaS customers. In Proceedings of APSEC 2010 Cloud Workshop. Furthermore, web services are the largest implementation technology in cloud environments. Apocryphal accounts can let attackers perform any malicious activity without being identified [16]. That uncertainty has consistently led information executives to state that security is their number one concern with Cloud Computing [10]. Bezemer C-P, Zaidman A: Multi-tenant SaaS applications: maintenance dream or nightmare? With a private cloud, your organization will have total control over the solution from top to bottom. Users are entitled to run any software with full control and management on the resources allocated to them [18]. Virtual networks are also target for some attacks especially when communicating with remote virtual machines. The VMM is a low-level software that controls and monitors its virtual machines, so as any traditional software it entails security flaws [45]. Online. This can be possible because VM migration transfer the data over network channels that are often insecure, such as the Internet. 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. Las Vegas, US: CSREA Press; 2010:36–42. Moving critical applications and sensitive data to public cloud environments is of great concern for those corporations that are moving beyond their data center’s network under their control. In the 7th International Conference on Informatics and Systems (INFOS), Potsdam, Germany. It provides the following security management features: access control framework, image filters, provenance tracking system, and repository maintenance services. NY, USA: ACM New York; 2009:128–133. This technique consists in first breaking down sensitive data into insignificant fragments, so any fragment does not have any significant information by itself. Attack vect… 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. In the first maturity model, each customer has his own customized instance of the software. OWASP: The Ten most critical Web application Security risks. <> However, one limitation of this approach is that filters may not be able to scan all malware or remove all the sensitive data from the images.

Sending or storing encrypted data in the cloud will ensure that data is secure. Once the sources had been defined, it was necessary to describe the process and the criteria for study selection and evaluation. Security Issues in Cloud Deployment Models. This paper reviewed various security issues inherent in the PaaS cloud model, classified them according to the essential cloud characteristics and finally recommended high-level solutions to the identified security issues. The virtual network model is composed of three layers: routing layers, firewall, and shared networks, which can prevent VMs from sniffing and spoofing.

Some confidential information such as passwords or cryptographic keys can be recorded while an image is being created. Available: . Each provider is responsible for securing his own services, which may result in an inconsistent combination of security models. Cloud Computing appears as a computational paradigm as well as a distribution architecture and its main objective is to provide secure, quick, convenient data storage and net computing service, with all computing resources visualized as services and delivered over the Internet [2, 3]. 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. Santos N, Gummadi KP, Rodrigues R: Towards Trusted Cloud Computing. Infrastructure as a Service (IaaS). Popovic K, Hocenski Z: Cloud Computing Security issues and challenges. This useful feature can also raise security problems [42, 43, 47]. However, it also exposes the service to additional security risks. For this analysis, we focus mainly on technology-based vulnerabilities; however, there are other vulnerabilities that are common to any organization, but they have to be taken in consideration since they can negatively impact the security of the cloud and its underlying platform. Traditional security mechanisms may not work well in cloud environments because it is a complex architecture that is composed of a combination of different technologies.

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? Even when developers are in control of the security of their applications, they do not have the assurance that the development environment tools provided by a PaaS provider are secure. - Provides ability to pool computing resources (e.g., Linux clustering). https://doi.org/10.1186/1869-0238-4-5, DOI: https://doi.org/10.1186/1869-0238-4-5. 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. [51] presents a virtual network framework that secures the communication among virtual machines. It groups virtual machines that have common objectives into workloads named Trusted Virtual Domains (TVDs). These malicious images can be the starting point of the proliferation of malware by injecting malicious code within other virtual machines in the creation process. <> In IEEE International Carnahan Conference on Security Technology (ICCST), KS, USA. Security Implications: PaaS PaaS: Virtual Environments - Provides dynamic load balancing capacity across multiple file systems and machines. Understanding what vulnerabilities exist in Cloud Computing will help organizations to make the shift towards the Cloud. However, the underlying compute, network, and storage infrastructure is controlled by cloud providers. The NIST Cloud Computing Standards Roadmap Working Group has gathered high level standards that are relevant for Cloud Computing. Mather T, Kumaraswamy S, Latif S: Cloud Security and Privacy.

Owens K: Securing virtual compute infrastructure in the Cloud. For instance, in threat T10, an attacker can read or tamper with the contents of the VM state files during live migration. In First International Conference on Cloud Computing (CloudCom), Beijing, China. Technical report, Dept. Future Internet 2012, 4(2):469–487. For each vulnerability and threat, we identify what cloud service model or models are affected by these security problems. 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. In 1st International Conference on Cloud Computing (CloudCom), Beijing, China. 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. 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. Before analyzing security challenges in Cloud Computing, we need to understand the relationships and dependencies between these cloud service models [4]. Beijing, China: Springer Berlin Heidelberg; 2009:69–79. Privileged users such as cloud administrators usually have unlimited access to the cloud data. Table 2 presents an analysis of vulnerabilities in Cloud Computing.

Furthermore, virtual machines are able to be rolled back to their previous states if an error happens. According to the Cloud Security Alliancethe list of the main cloud security threats includes the following: 1) Malware Injections. Cookies policy. NY, USA: ACM New York; 2009:91–96. 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. Traditional web applications, data hosting, and virtualization have been looked over, but some of the solutions offered are immature or inexistent.

We also want to thank the GSyA Research Group at the University of Castilla-La Mancha, in Ciudad Real, Spain for collaborating with us in this project. Available: . This framework is based on Xen which offers two configuration modes for virtual networks: “bridged” and “routed”. Network components are shared by different tenants due to resource pooling. This work was supported in part by the NSF (grants OISE-0730065). In SaaS, organizational data is often processed in plaintext and stored in the cloud. In Trusted Infrastructure Technologies Conference, 2008. Tebaa M, El Hajji S, El Ghazi A: Homomorphic encryption method applied to Cloud Computing. Current homomorphic encryption schemes support limited number of homomorphic operations such as addition and multiplication. An evaluation of this approach was not performed when this publication was published. 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 In Proceedings of the 2009 ACM workshop on Cloud Computing Security. In Second International Conference on Future Networks (ICFN’10), Sanya, Hainan, China. We put more emphasis on threats that are associated with data being stored and processed remotely, sharing resources and the usage of virtualization. The capability provided to the consumer is to use the provider’s applications running on a cloud infrastructure. Web applications can be an easy target because they are exposed to the public including potential attackers. 10.5121/ijnsa.2011.3103. VMs located on the same server can share CPU, memory, I/O, and others. J Syst Softw 2007, 80(4):571–583. Workshop on Dependability Aspects of Data Warehousing and Mining Applications (DAWAM 2009), in conjunction with the 4th Int.Conf. The security issues are a little different, depending on whether you use a public cloud or private cloud implementation of IaaS. As described in this paper, storage, virtualization, and networks are the biggest security concerns in Cloud Computing. There are more security issues, but it is a good start for securing web applications. IaaS & Security. The TCCP adds two fundamental elements: a trusted virtual machine monitor (TVMM) and a trusted coordinator (TC). This model has drawbacks, but security issues are not so bad compared with the other models. For the final model, applications can be scaled up by moving the application to a more powerful server if needed. Reuben JS: A survey on virtual machine Security. [67] this technique aims to provide intrusion tolerance and, in consequence, secure storage. Waltham, MA: Elsevier Inc; 2011. The authors in [78] claimed that TCCP has a significant downside due to the fact that all the transactions have to verify with the TC which creates an overload. Additionally, it is important to understand the lifecycle of the VMs and their changes in states as they move through the environment. In Security engineering for Cloud Computing: approaches and Tools. Crossroads 2010, 16(3):23–25. 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]. Once again, security cannot be … For example, a malicious VM can infer some information about other VMs through shared memory or other shared resources without need of compromising the hypervisor [46]. Security controls in Cloud Computing are, for the most part, no different than security controls in any IT environment. 13, V13–39. stream In Proceedings of the 3rd ACM workshop on Cloud Computing Security workshop. 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]. We have presented security issues for cloud models: IaaS, PaaS, and IaaS, which vary depending on the model. DC, USA: IEEE Computer Society Washington; 2010:18–21. 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. 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. Edited by: Antonopoulos N, Gillam L. Springer-Verlag: 2010; 2010. Most developers still deal with application security issues in isolation, without understanding the security of the ""full stack"". This is true in any type of organization; however, in the cloud, it has a bigger impact because there are more people that interact with the cloud: cloud providers, third-party providers, suppliers, organizational customers, and end-users. Heidelberg: Springer-Verlag Berlin; 2009. Also cloud providers can subcontract other services such as backup from third-party service providers, which may raise concerns. Gaithersburg, MD: NIST, Special Publication 800–145; 2011. The authors conducted some experiments to evaluate their framework, and the results revealed that the security policies are in place throughout live migration. In Proceedings of the 2012 ACM conference on Computer and communications security, New York, NY, USA. In Proceedings of the 40th annual Hawaii International conference on system sciences. IaaS providers must undertake a substantial effort to secure their systems in order to minimize these threats that result from creation, communication, monitoring, modification, and mobility [42]. PaaS providers are responsible for securing the platform software stack that includes the runtime engine that runs the customer applications. Mashups combine more than one source element into a single integrated unit. SIGOPS Oper. 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]. Sydney, Australia: APSEC; 2010. Additionally, security controls and self-service entitlements offered by the PaaS platform could pose a problem if not properly configured.

In this section, we provide a brief description of each countermeasure mentioned before, except for threats T02 and T07. Unfortunately, integrating security into these solutions is often perceived as making them more rigid [4]. The importance of Cloud Computing is increasing and it is receiving a growing attention in the scientific and industrial communities. Wu and et al.

It also creates confusion over which service provider is responsible once an attack happens. The security of this data while it is being processed, transferred, and stored depends on the provider. Pittsburgh, PA: CMU-CS-01–120; 2001. [Online]. Implementation, Management, and Security, CRC Press; 2009. 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].

A SaaS provider may rent a development environment from a PaaS provider, which might also rent an infrastructure from an IaaS provider. 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. In the cloud, security is a shared responsibility between the cloud provider and the customer. 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.

Accessing applications over the internet via web browser makes access from any network device easier, including public computers and mobile devices. Besides secure development techniques, developers need to be educated about data legal issues as well, so that data is not stored in inappropriate locations. IaaS provides a pool of resources such as servers, storage, networks, and other computing resources in the form of virtualized systems, which are accessed through the Internet [24]. Security of PaaS clouds is considered from multiple perspective including access control, service continuity and privacy while protecting together the service provider and the user. Virtualization which allows multiple users to share a physical server is one of the major concerns for cloud users. Unlike physical servers, VMs have two boundaries: physical and virtual [24]. Security policies are needed to ensure that customer’s data are kept separate from other customers [35]. We have expressed three of the items in Table 4 as misuse patterns [46]. Later, we will analyze the security issues in Cloud Computing identifying the main vulnerabilities for clouds, the most important threats in clouds, and all available countermeasures for these threats and vulnerabilities.
