PALM [64] proposes a secure migration system that provides VM live migration capabilities under the condition that a VMM-protected system is present and active. In the cloud, security is a shared responsibility between the cloud provider and the customer. 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. PaaS as well as SaaS are hosted on top of IaaS; thus, any breach in IaaS will impact the security of both PaaS and SaaS services, but also it may be true on the other way around. Viega J: Cloud Computing and the common Man. of Computer Science, University of California, Santa Barbara: ; 2009. http://www.academia.edu/760613/Survey_of_Virtual_Machine_Migration_Techniques, Ranjith P, Chandran P, Kaleeswaran S: On covert channels between virtual machines. 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? J Syst Softw 2007, 80(4):571–583. Data security is a common concern for any technology, but it becomes a major challenge when SaaS users have to rely on their providers for proper security [12, 21, 36]. 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. We have expressed three of the items in Table 4 as misuse patterns [46]. Resolving such problems may increase the usage of cloud thereby reducing the amount spent for resources. I. 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. Zhao G, Liu J, Tang Y, Sun W, Zhang F, Ye X, Tang N: Cloud Computing: A Statistics Aspect of Users. Cloud Computing Security Issues and Challenges Dheeraj Singh Negi 2. Thus, these images are fundamental for the the overall security of the cloud [46, 49]. Accessed: 05-Jun-2011 http://msdn.microsoft.com/en-us/library/aa479086.aspx Online. IEEE Asia-Pacific: APSCC; 2009:273–278. NY, USA: ACM New York; 2009:128–133. J Netw Comput Appl 2011, 34(1):1–11. Springer Nature. Wu and et al. 2010. 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. As a consequence of these deep dependencies, any attack to any cloud service layer can compromise the upper layers. Countermeasures are proposed and discussed. Cloud Security Alliance: Top Threats to Cloud Computing V1.0. TR/SE-0401 TR/SE-0401. This threat is feasible because any legitimate user can create a VM image and publish it on the provider’s repository where other users can retrieve them. J Internet Serv Appl 4, 5 (2013). Platform as a Service (PaaS). This question had to be related with the aim of this work; that is to identify and relate vulnerabilities and threats with possible solutions. 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]. The authors in [77] provided some real-world cloud applications where some basic homomorphic operations are needed. 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. Morsy MA, Grundy J, Müller I: An analysis of the Cloud Computing Security problem. A malicious virtual machine can be migrated to another host (with another VMM) compromising it. 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]. Manage cookies/Do not sell my data we use in the preference centre. Ertaul L, Singhal S, Gökay S: Security challenges in Cloud Computing. 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. We put more emphasis on threats that are associated with data being stored and processed remotely, sharing resources and the usage of virtualization. The VMM is a low-level software that controls and monitors its virtual machines, so as any traditional software it entails security flaws [45]. Washington, DC, USA: IEEE Computer Society; 2010:378–380. With a private cloud, your organization will have total control over the solution from top to bottom. Cloud providers have to decrypt cipher data in order to process it, which raises privacy concerns. 10.1007/s11416-012-0168-x. endobj Cloud Security Alliance (CSA) is a non-profit organization that promotes the use of best practices in order to provide security in cloud environments. In Proceedings of the 40th annual Hawaii International conference on system sciences. IEEE Security Privacy 2011, 9(2):50–57. In this section, we provide a brief description of each countermeasure mentioned before, except for threats T02 and T07. This useful feature can also raise security problems [42, 43, 47]. Web applications can be an easy target because they are exposed to the public including potential attackers. Some of these vulnerabilities are the following: Lack of employee screening and poor hiring practices [16] – some cloud providers may not perform background screening of their employees or providers. Nevertheless, there are still a few security issues in cloud computing that are worth being aware of. In 1st International Conference on Cloud Computing (CloudCom), Beijing, China. 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. Part of 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. In Proceedings of the 4th Int. 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. Most developers still deal with application security issues in isolation, without understanding the security of the "“full stack”". Future Internet 2012, 4(2):430–450. As you consider and evaluate public cloud services, it’s critical to understand the shared responsibility model and which security tasks are handled by the cloud provider and which tasks are handled by you. As mentioned before, sharing resources allows attackers to launch cross-tenant attacks [20]. It also creates confusion over which service provider is responsible once an attack happens. INTRODUCTION Cloud Computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources(e.g. Largely because of the relatively lower degree of abstraction, IaaS offers greater tenant or customer control over security than do PaaS or SaaS [10]. Also, another challenge is that there are different types of virtualization technologies, and each type may approach security mechanisms in different ways. We have focused on this distinction, where we consider important to understand these issues. From Table 2, we can conclude that data storage and virtualization are the most critical and an attack to them can do the most harm. With SaaS, the burden of security lies with the cloud provider. 10.1145/1743546.1743565. 2010. Sebastopol, CA: O’Reilly Media, Inc.; 2009. International Conference on Signal Acquisition and Processing (ICSAP’10) 2010, 278–281. As described in this paper, storage, virtualization, and networks are the biggest security concerns in Cloud Computing. The three basic operations for cloud data are transfer, store, and process. [67] this technique aims to provide intrusion tolerance and, in consequence, secure storage. 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. Syst. 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. 1 0 obj That uncertainty has consistently led information executives to state that security is their number one concern with Cloud Computing [10]. Since Cloud Computing leverages many technologies, it also inherits their security issues. IaaS essentially refers to purchasing the basic storage, processing power and networking to support the delivery of cloud computing applications. Chandramouli R, Mell P: State of Security readiness. These issues are primarily related to the safety of the data flowing through and being stored in the cloud, with sample issues including data availability, data access and data privacy. Privacy Virtual networks are also target for some attacks especially when communicating with remote virtual machines. As with SaaS and IaaS, PaaS depends on a secure and reliable network and secure web browser. IBM J Res Dev 2009, 53(4):560–571. The security of this data while it is being processed, transferred, and stored depends on the provider. We have presented security issues for cloud models: IaaS, PaaS, and IaaS, which vary depending on the model. volume 10. Online. VMs located on the same server can share CPU, memory, I/O, and others. It’s important to understand the division of responsibility between you and Microsoft. Grobauer B, Walloschek T, Stocker E: Understanding Cloud Computing vulnerabilities. Accessed: 15-Jul-2011. 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. Using covert channels, two VMs can communicate bypassing all the rules defined by the security module of the VMM [48]. Security Issues, Data Security, Private Protection. HyperSafe’s goal is to protect type I hypervisors using two techniques: non-bypassable memory lockdown which protects write-protected memory pages from being modified, and restricted pointed indexing that converts control data into pointer indexes. PaaS security practices. Fernandez EB, Ajaj O, Buckley I, Delessy-Gassant N, Hashizume K, Larrondo-Petrie MM: A survey of patterns for Web services Security and reliability standards. Venkatesha S, Sadhu S, Kintali S: Survey of virtual machine migration techniques. 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. Sydney, Australia: APSEC; 2010. In Proceedings of the 2011 International conference on intelligent semantic Web-services and applications. 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. This analysis offers a brief description of the vulnerabilities, and indicates what cloud service models (SPI) can be affected by them. Moreover, virtualization introduces the ability to migrate virtual machines between physical servers for fault tolerance, load balancing or maintenance [16, 46]. The RMF is your best bet for resolving security control issues on the PaaS. Apocryphal accounts can let attackers perform any malicious activity without being identified [16]. Accessed: 05-Jun-2011. One can either create her own VM image from scratch, or one can use any image stored in the provider’s repository. The TC manages a set of trusted nodes that run TVMMs, and it is maintained but a trusted third party. Crossroads 2010, 16(3):23–25. CA, USA: USENIX Association Berkeley; 2009. In International Conference on Intelligent Computing and Cognitive Informatics (ICICCI), Hangzhou, China. Most developers still deal with application security issues in isolation, without understanding the security of the ""full stack"". The public cloud refers to software, infrastructure, or platforms offered as a service by 3 rd parties over the Internet, referred to as Cloud Service Providers or CSPs. IaaS & Security.

To alleviate these concerns, a cloud solution provider must ensure that customers will continue to have the same security and privacy controls over their applications and services, provide evidence to customers that their organization are secure and they can meet their service-level agreements, and that they can prove compliance to auditors [12]. Terms and Conditions, [Online]. Washington DC, USA: IEEE Computer Society; 2010:395–398. For example, an attacker with a valid account can create an image containing malicious code such as a Trojan horse. NY, USA: ACM New York; 2010:88–92. Commun ACM 2010, 53(6):46–51. The PaaS customer is responsible for securing its applications, data, and user access. The inclusion and exclusion criteria of this study were based on the research question. Cite this article. A security checklist for SaaS, PaaS and IaaS cloud models Key security issues can vary depending on the cloud model you're using. They control the software running in their virtual machines, and they are responsible to configure security policies correctly [41]. Sharing resources between VMs may decrease the security of each VM. 4 0 obj Vordel CTO Mark O'Neill looks at 5 critical challenges. PaaS (Platform-as-a-Service) ist eine vollständige Entwicklungs- und Bereitstellungsumgebung in der Cloud, über die Sie Zugang zu den erforderlichen Ressourcen erhalten, um verschiedenste Lösungen bereitstellen zu können – von einfachen cloudbasierten Apps bis hin zu ausgereiften cloudfähigen Unternehmensanwendungen. SaaS users have less control over security among the three fundamental delivery models in the cloud. [52] proposes a security framework that customizes security policies for each virtual machine, and it provides continuous protection thorough virtual machine live migration. The capability provided to the consumer is to use the provider’s applications running on a cloud infrastructure. The authors conducted some experiments to evaluate their framework, and the results revealed that the security policies are in place throughout live migration. 2012. 10.1007/s13174-010-0007-6. Security web services standards describe how to secure communication between applications through integrity, confidentiality, authentication and authorization. Edited by: Antonopoulos N, Gillam L. Springer-Verlag: 2010; 2010. Cloud Computing enables ubiquitous, 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. 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. Next, in Section 3 we define in depth the most important security aspects for each layer of the Cloud model. These applications are typically delivered via the Internet through a Web browser [12, 22]. on Availability, Reliability, and Security (ARES 2009), Fukuoka, Japan. Washington, DC, USA: IEEE Computer Society; 2012:86–89. In the second model, the vendor also provides different instances of the applications for each customer, but all instances use the same application code. Keiko Hashizume. Implementation, Management, and Security, CRC Press; 2009. However, web services also lead to several challenges that need to be addressed. 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. This technique consists in first breaking down sensitive data into insignificant fragments, so any fragment does not have any significant information by itself. 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. Computer 2009, 42(8):106–108. Owens K: Securing virtual compute infrastructure in the Cloud. Washington, DC, USA: IEEE Computer Society; 2008:9–18. In Proceedings of the 3rd ACM workshop on Cloud Computing Security workshop. Moreover, most compliance standards do not envision compliance with regulations in a world of Cloud Computing [12]. [68] proposes to secure data using digital signature with RSA algorithm while data is being transferred over the Internet. Additionally, it is important to understand the lifecycle of the VMs and their changes in states as they move through the environment. Table 3 presents an overview of threats in Cloud Computing. Security Implications: PaaS PaaS: Virtual Environments - Provides dynamic load balancing capacity across multiple file systems and machines. CSA has issued an Identity and Access Management Guidance [65] which provides a list of recommended best practiced to assure identities and secure access management. Accessed: 02-Aug-2011 The Register, 08-Jun-2009.

SSL is the underpinnings of most of the "security" utilized in the cloud and, for that matter, the Internet in general. 2008, 42(1):40–47. Here, we present a list of vulnerabilities and threats, and we also indicate what cloud service models can be affected by them. In Cloud Computing. In International Conference on Management and Service Science. Las Vegas, US: CSREA Press; 2010:36–42. In Proceedings of the IEEE symposium on Security and privacy. Malicious users can store images containing malicious code into public repositories compromising other users or even the cloud system [20, 24, 25]. VM images are dormant artifacts that are hard to patch while they are offline [50]. Washington, DC, USA: IEEE Computer Society; 2010:35–41. As a result, security is sometimes inconsistent, and can be seen as a barrier to moving applications to the cloud. MASS’09. Once the sources had been defined, it was necessary to describe the process and the criteria for study selection and evaluation.

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. As a consequence of these deep dependencies, any attack to any cloud service layer can compromise the upper layers. Countermeasures are proposed and discussed. Cloud Security Alliance: Top Threats to Cloud Computing V1.0. TR/SE-0401 TR/SE-0401. This threat is feasible because any legitimate user can create a VM image and publish it on the provider’s repository where other users can retrieve them. J Internet Serv Appl 4, 5 (2013). Platform as a Service (PaaS). This question had to be related with the aim of this work; that is to identify and relate vulnerabilities and threats with possible solutions. 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]. The authors in [77] provided some real-world cloud applications where some basic homomorphic operations are needed. 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. Morsy MA, Grundy J, Müller I: An analysis of the Cloud Computing Security problem. A malicious virtual machine can be migrated to another host (with another VMM) compromising it. 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]. Manage cookies/Do not sell my data we use in the preference centre. Ertaul L, Singhal S, Gökay S: Security challenges in Cloud Computing. 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. We put more emphasis on threats that are associated with data being stored and processed remotely, sharing resources and the usage of virtualization. The VMM is a low-level software that controls and monitors its virtual machines, so as any traditional software it entails security flaws [45]. Washington, DC, USA: IEEE Computer Society; 2010:378–380. With a private cloud, your organization will have total control over the solution from top to bottom. Cloud providers have to decrypt cipher data in order to process it, which raises privacy concerns. 10.1007/s11416-012-0168-x. endobj Cloud Security Alliance (CSA) is a non-profit organization that promotes the use of best practices in order to provide security in cloud environments. In Proceedings of the 40th annual Hawaii International conference on system sciences. IEEE Security Privacy 2011, 9(2):50–57. In this section, we provide a brief description of each countermeasure mentioned before, except for threats T02 and T07. This useful feature can also raise security problems [42, 43, 47]. Web applications can be an easy target because they are exposed to the public including potential attackers. Some of these vulnerabilities are the following: Lack of employee screening and poor hiring practices [16] – some cloud providers may not perform background screening of their employees or providers. Nevertheless, there are still a few security issues in cloud computing that are worth being aware of. In 1st International Conference on Cloud Computing (CloudCom), Beijing, China. 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. Part of 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. In Proceedings of the 4th Int. 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. Most developers still deal with application security issues in isolation, without understanding the security of the "“full stack”". Future Internet 2012, 4(2):430–450. As you consider and evaluate public cloud services, it’s critical to understand the shared responsibility model and which security tasks are handled by the cloud provider and which tasks are handled by you. As mentioned before, sharing resources allows attackers to launch cross-tenant attacks [20]. It also creates confusion over which service provider is responsible once an attack happens. INTRODUCTION Cloud Computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources(e.g. Largely because of the relatively lower degree of abstraction, IaaS offers greater tenant or customer control over security than do PaaS or SaaS [10]. Also, another challenge is that there are different types of virtualization technologies, and each type may approach security mechanisms in different ways. We have focused on this distinction, where we consider important to understand these issues. From Table 2, we can conclude that data storage and virtualization are the most critical and an attack to them can do the most harm. With SaaS, the burden of security lies with the cloud provider. 10.1145/1743546.1743565. 2010. Sebastopol, CA: O’Reilly Media, Inc.; 2009. International Conference on Signal Acquisition and Processing (ICSAP’10) 2010, 278–281. As described in this paper, storage, virtualization, and networks are the biggest security concerns in Cloud Computing. The three basic operations for cloud data are transfer, store, and process. [67] this technique aims to provide intrusion tolerance and, in consequence, secure storage. 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. Syst. 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. 1 0 obj That uncertainty has consistently led information executives to state that security is their number one concern with Cloud Computing [10]. Since Cloud Computing leverages many technologies, it also inherits their security issues. IaaS essentially refers to purchasing the basic storage, processing power and networking to support the delivery of cloud computing applications. Chandramouli R, Mell P: State of Security readiness. These issues are primarily related to the safety of the data flowing through and being stored in the cloud, with sample issues including data availability, data access and data privacy. Privacy Virtual networks are also target for some attacks especially when communicating with remote virtual machines. As with SaaS and IaaS, PaaS depends on a secure and reliable network and secure web browser. IBM J Res Dev 2009, 53(4):560–571. The security of this data while it is being processed, transferred, and stored depends on the provider. We have presented security issues for cloud models: IaaS, PaaS, and IaaS, which vary depending on the model. volume 10. Online. VMs located on the same server can share CPU, memory, I/O, and others. It’s important to understand the division of responsibility between you and Microsoft. Grobauer B, Walloschek T, Stocker E: Understanding Cloud Computing vulnerabilities. Accessed: 15-Jul-2011. 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. Using covert channels, two VMs can communicate bypassing all the rules defined by the security module of the VMM [48]. Security Issues, Data Security, Private Protection. HyperSafe’s goal is to protect type I hypervisors using two techniques: non-bypassable memory lockdown which protects write-protected memory pages from being modified, and restricted pointed indexing that converts control data into pointer indexes. PaaS security practices. Fernandez EB, Ajaj O, Buckley I, Delessy-Gassant N, Hashizume K, Larrondo-Petrie MM: A survey of patterns for Web services Security and reliability standards. Venkatesha S, Sadhu S, Kintali S: Survey of virtual machine migration techniques. 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. Sydney, Australia: APSEC; 2010. In Proceedings of the 2011 International conference on intelligent semantic Web-services and applications. 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. This analysis offers a brief description of the vulnerabilities, and indicates what cloud service models (SPI) can be affected by them. Moreover, virtualization introduces the ability to migrate virtual machines between physical servers for fault tolerance, load balancing or maintenance [16, 46]. The RMF is your best bet for resolving security control issues on the PaaS. Apocryphal accounts can let attackers perform any malicious activity without being identified [16]. Accessed: 05-Jun-2011. One can either create her own VM image from scratch, or one can use any image stored in the provider’s repository. The TC manages a set of trusted nodes that run TVMMs, and it is maintained but a trusted third party. Crossroads 2010, 16(3):23–25. CA, USA: USENIX Association Berkeley; 2009. In International Conference on Intelligent Computing and Cognitive Informatics (ICICCI), Hangzhou, China. Most developers still deal with application security issues in isolation, without understanding the security of the ""full stack"". The public cloud refers to software, infrastructure, or platforms offered as a service by 3 rd parties over the Internet, referred to as Cloud Service Providers or CSPs. IaaS & Security.

To alleviate these concerns, a cloud solution provider must ensure that customers will continue to have the same security and privacy controls over their applications and services, provide evidence to customers that their organization are secure and they can meet their service-level agreements, and that they can prove compliance to auditors [12]. Terms and Conditions, [Online]. Washington DC, USA: IEEE Computer Society; 2010:395–398. For example, an attacker with a valid account can create an image containing malicious code such as a Trojan horse. NY, USA: ACM New York; 2010:88–92. Commun ACM 2010, 53(6):46–51. The PaaS customer is responsible for securing its applications, data, and user access. The inclusion and exclusion criteria of this study were based on the research question. Cite this article. A security checklist for SaaS, PaaS and IaaS cloud models Key security issues can vary depending on the cloud model you're using. They control the software running in their virtual machines, and they are responsible to configure security policies correctly [41]. Sharing resources between VMs may decrease the security of each VM. 4 0 obj Vordel CTO Mark O'Neill looks at 5 critical challenges. PaaS (Platform-as-a-Service) ist eine vollständige Entwicklungs- und Bereitstellungsumgebung in der Cloud, über die Sie Zugang zu den erforderlichen Ressourcen erhalten, um verschiedenste Lösungen bereitstellen zu können – von einfachen cloudbasierten Apps bis hin zu ausgereiften cloudfähigen Unternehmensanwendungen. SaaS users have less control over security among the three fundamental delivery models in the cloud. [52] proposes a security framework that customizes security policies for each virtual machine, and it provides continuous protection thorough virtual machine live migration. The capability provided to the consumer is to use the provider’s applications running on a cloud infrastructure. The authors conducted some experiments to evaluate their framework, and the results revealed that the security policies are in place throughout live migration. 2012. 10.1007/s13174-010-0007-6. Security web services standards describe how to secure communication between applications through integrity, confidentiality, authentication and authorization. Edited by: Antonopoulos N, Gillam L. Springer-Verlag: 2010; 2010. Cloud Computing enables ubiquitous, 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. 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. Next, in Section 3 we define in depth the most important security aspects for each layer of the Cloud model. These applications are typically delivered via the Internet through a Web browser [12, 22]. on Availability, Reliability, and Security (ARES 2009), Fukuoka, Japan. Washington, DC, USA: IEEE Computer Society; 2012:86–89. In the second model, the vendor also provides different instances of the applications for each customer, but all instances use the same application code. Keiko Hashizume. Implementation, Management, and Security, CRC Press; 2009. However, web services also lead to several challenges that need to be addressed. 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. This technique consists in first breaking down sensitive data into insignificant fragments, so any fragment does not have any significant information by itself. 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. Computer 2009, 42(8):106–108. Owens K: Securing virtual compute infrastructure in the Cloud. Washington, DC, USA: IEEE Computer Society; 2008:9–18. In Proceedings of the 3rd ACM workshop on Cloud Computing Security workshop. Moreover, most compliance standards do not envision compliance with regulations in a world of Cloud Computing [12]. [68] proposes to secure data using digital signature with RSA algorithm while data is being transferred over the Internet. Additionally, it is important to understand the lifecycle of the VMs and their changes in states as they move through the environment. Table 3 presents an overview of threats in Cloud Computing. Security Implications: PaaS PaaS: Virtual Environments - Provides dynamic load balancing capacity across multiple file systems and machines. CSA has issued an Identity and Access Management Guidance [65] which provides a list of recommended best practiced to assure identities and secure access management. Accessed: 02-Aug-2011 The Register, 08-Jun-2009. 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. 2009.

In both SaaS and PaaS, data is associated with an application running in the cloud. SSL is the underpinnings of most of the "security" utilized in the cloud and, for that matter, the Internet in general. 2008, 42(1):40–47. Here, we present a list of vulnerabilities and threats, and we also indicate what cloud service models can be affected by them. In Cloud Computing. In International Conference on Management and Service Science. Las Vegas, US: CSREA Press; 2010:36–42. In Proceedings of the IEEE symposium on Security and privacy. Malicious users can store images containing malicious code into public repositories compromising other users or even the cloud system [20, 24, 25]. VM images are dormant artifacts that are hard to patch while they are offline [50]. Washington, DC, USA: IEEE Computer Society; 2010:35–41. As a result, security is sometimes inconsistent, and can be seen as a barrier to moving applications to the cloud. MASS’09. Once the sources had been defined, it was necessary to describe the process and the criteria for study selection and evaluation.

Compared to traditional technologies, the cloud has many specific features, such as its large scale and the fact that resources belonging to cloud providers are completely distributed, heterogeneous and totally virtualized. The following list of sources has been considered: ScienceDirect, ACM digital library, IEEE digital library, Scholar Google and DBLP. 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. Data may be stored on different places with different legal regimes that can compromise its privacy and security. In First International Conference on Cloud Computing (CloudCom), Beijing, China. An evaluation of this approach was not performed when this publication was published. Hashizume K, Yoshioka N, Fernandez EB: Three misuse patterns for Cloud Computing. Therefore, any vulnerability associated to these technologies also affects the cloud, and it can even have a significant impact.

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. For the final model, applications can be scaled up by moving the application to a more powerful server if needed. Beijing, China: Springer Berlin Heidelberg; 2009:69–79. 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. Threat 11 is another cloud threat where an attacker creates malicious VM image containing any type of virus or malware. 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. Zhang Y, Juels A, Reiter MK, Ristenpart T: Cross-VM side channels and their use to extract private keys. 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.

PALM [64] proposes a secure migration system that provides VM live migration capabilities under the condition that a VMM-protected system is present and active. In the cloud, security is a shared responsibility between the cloud provider and the customer. 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. PaaS as well as SaaS are hosted on top of IaaS; thus, any breach in IaaS will impact the security of both PaaS and SaaS services, but also it may be true on the other way around. Viega J: Cloud Computing and the common Man. of Computer Science, University of California, Santa Barbara: ; 2009. http://www.academia.edu/760613/Survey_of_Virtual_Machine_Migration_Techniques, Ranjith P, Chandran P, Kaleeswaran S: On covert channels between virtual machines. 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? J Syst Softw 2007, 80(4):571–583. Data security is a common concern for any technology, but it becomes a major challenge when SaaS users have to rely on their providers for proper security [12, 21, 36]. 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. We have expressed three of the items in Table 4 as misuse patterns [46]. Resolving such problems may increase the usage of cloud thereby reducing the amount spent for resources. I. 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. Zhao G, Liu J, Tang Y, Sun W, Zhang F, Ye X, Tang N: Cloud Computing: A Statistics Aspect of Users. Cloud Computing Security Issues and Challenges Dheeraj Singh Negi 2. Thus, these images are fundamental for the the overall security of the cloud [46, 49]. Accessed: 05-Jun-2011 http://msdn.microsoft.com/en-us/library/aa479086.aspx Online. IEEE Asia-Pacific: APSCC; 2009:273–278. NY, USA: ACM New York; 2009:128–133. J Netw Comput Appl 2011, 34(1):1–11. Springer Nature. Wu and et al. 2010. 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. As a consequence of these deep dependencies, any attack to any cloud service layer can compromise the upper layers. Countermeasures are proposed and discussed. Cloud Security Alliance: Top Threats to Cloud Computing V1.0. TR/SE-0401 TR/SE-0401. This threat is feasible because any legitimate user can create a VM image and publish it on the provider’s repository where other users can retrieve them. J Internet Serv Appl 4, 5 (2013). Platform as a Service (PaaS). This question had to be related with the aim of this work; that is to identify and relate vulnerabilities and threats with possible solutions. 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]. The authors in [77] provided some real-world cloud applications where some basic homomorphic operations are needed. 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. Morsy MA, Grundy J, Müller I: An analysis of the Cloud Computing Security problem. A malicious virtual machine can be migrated to another host (with another VMM) compromising it. 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]. Manage cookies/Do not sell my data we use in the preference centre. Ertaul L, Singhal S, Gökay S: Security challenges in Cloud Computing. 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. We put more emphasis on threats that are associated with data being stored and processed remotely, sharing resources and the usage of virtualization. The VMM is a low-level software that controls and monitors its virtual machines, so as any traditional software it entails security flaws [45]. Washington, DC, USA: IEEE Computer Society; 2010:378–380. With a private cloud, your organization will have total control over the solution from top to bottom. Cloud providers have to decrypt cipher data in order to process it, which raises privacy concerns. 10.1007/s11416-012-0168-x. endobj Cloud Security Alliance (CSA) is a non-profit organization that promotes the use of best practices in order to provide security in cloud environments. In Proceedings of the 40th annual Hawaii International conference on system sciences. IEEE Security Privacy 2011, 9(2):50–57. In this section, we provide a brief description of each countermeasure mentioned before, except for threats T02 and T07. This useful feature can also raise security problems [42, 43, 47]. Web applications can be an easy target because they are exposed to the public including potential attackers. Some of these vulnerabilities are the following: Lack of employee screening and poor hiring practices [16] – some cloud providers may not perform background screening of their employees or providers. Nevertheless, there are still a few security issues in cloud computing that are worth being aware of. In 1st International Conference on Cloud Computing (CloudCom), Beijing, China. 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. Part of 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. In Proceedings of the 4th Int. 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. Most developers still deal with application security issues in isolation, without understanding the security of the "“full stack”". Future Internet 2012, 4(2):430–450. As you consider and evaluate public cloud services, it’s critical to understand the shared responsibility model and which security tasks are handled by the cloud provider and which tasks are handled by you. As mentioned before, sharing resources allows attackers to launch cross-tenant attacks [20]. It also creates confusion over which service provider is responsible once an attack happens. INTRODUCTION Cloud Computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources(e.g. Largely because of the relatively lower degree of abstraction, IaaS offers greater tenant or customer control over security than do PaaS or SaaS [10]. Also, another challenge is that there are different types of virtualization technologies, and each type may approach security mechanisms in different ways. We have focused on this distinction, where we consider important to understand these issues. From Table 2, we can conclude that data storage and virtualization are the most critical and an attack to them can do the most harm. With SaaS, the burden of security lies with the cloud provider. 10.1145/1743546.1743565. 2010. Sebastopol, CA: O’Reilly Media, Inc.; 2009. International Conference on Signal Acquisition and Processing (ICSAP’10) 2010, 278–281. As described in this paper, storage, virtualization, and networks are the biggest security concerns in Cloud Computing. The three basic operations for cloud data are transfer, store, and process. [67] this technique aims to provide intrusion tolerance and, in consequence, secure storage. 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. Syst. 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. 1 0 obj That uncertainty has consistently led information executives to state that security is their number one concern with Cloud Computing [10]. Since Cloud Computing leverages many technologies, it also inherits their security issues. IaaS essentially refers to purchasing the basic storage, processing power and networking to support the delivery of cloud computing applications. Chandramouli R, Mell P: State of Security readiness. These issues are primarily related to the safety of the data flowing through and being stored in the cloud, with sample issues including data availability, data access and data privacy. Privacy Virtual networks are also target for some attacks especially when communicating with remote virtual machines. As with SaaS and IaaS, PaaS depends on a secure and reliable network and secure web browser. IBM J Res Dev 2009, 53(4):560–571. The security of this data while it is being processed, transferred, and stored depends on the provider. We have presented security issues for cloud models: IaaS, PaaS, and IaaS, which vary depending on the model. volume 10. Online. VMs located on the same server can share CPU, memory, I/O, and others. It’s important to understand the division of responsibility between you and Microsoft. Grobauer B, Walloschek T, Stocker E: Understanding Cloud Computing vulnerabilities. Accessed: 15-Jul-2011. 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. Using covert channels, two VMs can communicate bypassing all the rules defined by the security module of the VMM [48]. Security Issues, Data Security, Private Protection. HyperSafe’s goal is to protect type I hypervisors using two techniques: non-bypassable memory lockdown which protects write-protected memory pages from being modified, and restricted pointed indexing that converts control data into pointer indexes. PaaS security practices. Fernandez EB, Ajaj O, Buckley I, Delessy-Gassant N, Hashizume K, Larrondo-Petrie MM: A survey of patterns for Web services Security and reliability standards. Venkatesha S, Sadhu S, Kintali S: Survey of virtual machine migration techniques. 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. Sydney, Australia: APSEC; 2010. In Proceedings of the 2011 International conference on intelligent semantic Web-services and applications. 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. This analysis offers a brief description of the vulnerabilities, and indicates what cloud service models (SPI) can be affected by them. Moreover, virtualization introduces the ability to migrate virtual machines between physical servers for fault tolerance, load balancing or maintenance [16, 46]. The RMF is your best bet for resolving security control issues on the PaaS. Apocryphal accounts can let attackers perform any malicious activity without being identified [16]. Accessed: 05-Jun-2011. One can either create her own VM image from scratch, or one can use any image stored in the provider’s repository. The TC manages a set of trusted nodes that run TVMMs, and it is maintained but a trusted third party. Crossroads 2010, 16(3):23–25. CA, USA: USENIX Association Berkeley; 2009. In International Conference on Intelligent Computing and Cognitive Informatics (ICICCI), Hangzhou, China. Most developers still deal with application security issues in isolation, without understanding the security of the ""full stack"". The public cloud refers to software, infrastructure, or platforms offered as a service by 3 rd parties over the Internet, referred to as Cloud Service Providers or CSPs. IaaS & Security.

Encryption techniques have been used for long time to secure sensitive data. Accessed: 15-Jul-2011 http://www.gartner.com/it/page.jsp?id=1454221 Online. To alleviate these concerns, a cloud solution provider must ensure that customers will continue to have the same security and privacy controls over their applications and services, provide evidence to customers that their organization are secure and they can meet their service-level agreements, and that they can prove compliance to auditors [12]. Terms and Conditions, [Online]. Washington DC, USA: IEEE Computer Society; 2010:395–398. For example, an attacker with a valid account can create an image containing malicious code such as a Trojan horse. NY, USA: ACM New York; 2010:88–92. Commun ACM 2010, 53(6):46–51. The PaaS customer is responsible for securing its applications, data, and user access. The inclusion and exclusion criteria of this study were based on the research question. Cite this article. A security checklist for SaaS, PaaS and IaaS cloud models Key security issues can vary depending on the cloud model you're using. They control the software running in their virtual machines, and they are responsible to configure security policies correctly [41]. Sharing resources between VMs may decrease the security of each VM. 4 0 obj Vordel CTO Mark O'Neill looks at 5 critical challenges. PaaS (Platform-as-a-Service) ist eine vollständige Entwicklungs- und Bereitstellungsumgebung in der Cloud, über die Sie Zugang zu den erforderlichen Ressourcen erhalten, um verschiedenste Lösungen bereitstellen zu können – von einfachen cloudbasierten Apps bis hin zu ausgereiften cloudfähigen Unternehmensanwendungen. SaaS users have less control over security among the three fundamental delivery models in the cloud. [52] proposes a security framework that customizes security policies for each virtual machine, and it provides continuous protection thorough virtual machine live migration. The capability provided to the consumer is to use the provider’s applications running on a cloud infrastructure. The authors conducted some experiments to evaluate their framework, and the results revealed that the security policies are in place throughout live migration. 2012. 10.1007/s13174-010-0007-6. Security web services standards describe how to secure communication between applications through integrity, confidentiality, authentication and authorization. Edited by: Antonopoulos N, Gillam L. Springer-Verlag: 2010; 2010. Cloud Computing enables ubiquitous, 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. 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. Next, in Section 3 we define in depth the most important security aspects for each layer of the Cloud model. These applications are typically delivered via the Internet through a Web browser [12, 22]. on Availability, Reliability, and Security (ARES 2009), Fukuoka, Japan. Washington, DC, USA: IEEE Computer Society; 2012:86–89. In the second model, the vendor also provides different instances of the applications for each customer, but all instances use the same application code. Keiko Hashizume. Implementation, Management, and Security, CRC Press; 2009. However, web services also lead to several challenges that need to be addressed. 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. This technique consists in first breaking down sensitive data into insignificant fragments, so any fragment does not have any significant information by itself. 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. Computer 2009, 42(8):106–108. Owens K: Securing virtual compute infrastructure in the Cloud. Washington, DC, USA: IEEE Computer Society; 2008:9–18. In Proceedings of the 3rd ACM workshop on Cloud Computing Security workshop. Moreover, most compliance standards do not envision compliance with regulations in a world of Cloud Computing [12]. [68] proposes to secure data using digital signature with RSA algorithm while data is being transferred over the Internet. Additionally, it is important to understand the lifecycle of the VMs and their changes in states as they move through the environment. Table 3 presents an overview of threats in Cloud Computing. Security Implications: PaaS PaaS: Virtual Environments - Provides dynamic load balancing capacity across multiple file systems and machines. CSA has issued an Identity and Access Management Guidance [65] which provides a list of recommended best practiced to assure identities and secure access management. Accessed: 02-Aug-2011 The Register, 08-Jun-2009. 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. 2009.

In both SaaS and PaaS, data is associated with an application running in the cloud. SSL is the underpinnings of most of the "security" utilized in the cloud and, for that matter, the Internet in general. 2008, 42(1):40–47. Here, we present a list of vulnerabilities and threats, and we also indicate what cloud service models can be affected by them. In Cloud Computing. In International Conference on Management and Service Science. Las Vegas, US: CSREA Press; 2010:36–42. In Proceedings of the IEEE symposium on Security and privacy. Malicious users can store images containing malicious code into public repositories compromising other users or even the cloud system [20, 24, 25]. VM images are dormant artifacts that are hard to patch while they are offline [50]. Washington, DC, USA: IEEE Computer Society; 2010:35–41. As a result, security is sometimes inconsistent, and can be seen as a barrier to moving applications to the cloud. MASS’09. Once the sources had been defined, it was necessary to describe the process and the criteria for study selection and evaluation.
