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. Zhang F, Huang Y, Wang H, Chen H, Zang B: PALM: Security Preserving VM Live Migration for Systems with VMM-enforced Protection. Bisong A, Rahman S: An overview of the Security concerns in Enterprise Cloud Computing. PaaS & Security - Problems, Solutions, Vendors PaaS & Security - Platform as a Service Platform-as-a-Service (Paas) is a cloud computing model where the service provider offers a platform that enables customers to develop, run, and manage applications. 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]. Also cloud providers can subcontract other services such as backup from third-party service providers, which may raise concerns. Each cloud service model comprises its own inherent security flaws; however, they also share some challenges that affect all of them. SaaS applications can be grouped into maturity models that are determined by the following characteristics: scalability, configurability via metadata, and multi-tenancy [30, 33]. In some cases, this switch has required major changes in software and caused project delays and even productivity losses. In Proceedings of the 2011 International conference on intelligent semantic Web-services and applications. Commun ACM 2010, 53(6):46–51. In [49], the authors propose a virtual machine image management system in a cloud computing environments. However, flaws in web applications may create vulnerabilities for the SaaS applications. SSL is the underpinnings of most of the "security" utilized in the cloud and, for that matter, the Internet in general. The most secure way is to hook each VM with its host by using dedicated physical channels. We have presented security issues for cloud models: IaaS, PaaS, and IaaS, which vary depending on the model. Rittinghouse JW, Ransome JF: Security in the Cloud. In Trusted Infrastructure Technologies Conference, 2008. 10.1145/1341312.1341321. In [70], they propose a method based on the application of fully homomorphic encryption to the security of clouds. The TC manages a set of trusted nodes that run TVMMs, and it is maintained but a trusted third party. Ormandy T: An empirical study into the Security exposure to hosts of hostile virtualized environments. IEEE Security Privacy 2011, 9(2):50–57. Gaithersburg, MD: NIST, Special Publication 800–145; 2011. Virtual machine security becomes as important as physical machine security, and any flaw in either one may affect the other [19]. Cloud Security Alliance (CSA) is a non-profit organization that promotes the use of best practices in order to provide security in cloud environments. As it is shown in Table 1, most of the approaches discussed identify, classify, analyze, and list a number of vulnerabilities and threats focused on Cloud Computing. An attacker can compromise the migration module in the VMM and transfer a victim virtual machine to a malicious server. 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. VMs can be on, off, or suspended which makes it harder to detect malware. Accessed: 15-Jul-2011. 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. Web application firewall routes all web traffic through the web application firewall which inspects specific threats. 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. There are some well-known encryption schemes such as AES (Advanced Encryption Standard). 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. SIGOPS Oper. SaaS provides software delivered over the web while PaaS offers development tools to create SaaS applications. 2 0 obj [51] presents a virtual network framework that secures the communication among virtual machines. The data breach has several consequences, some of which includes: Incident forensics and response leading to financial … Edited by: Antonopoulos N, Gillam L. Springer-Verlag: 2010; 2010. Carlin S, Curran K: Cloud Computing Security. Also, data backup is a critical aspect in order to facilitate recovery in case of disaster, but it introduces security concerns as well [21]. In Proceedings of the 4th Int. Cloud Computing is a relatively new concept that presents a good number of benefits for its users; however, it also raises some security problems which may slow down its use. Crossroads 2010, 16(3):23–25. However, most hypervisors use virtual networks to link VMs to communicate more directly and efficiently. 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. Thus, PaaS models also inherit security issues related to mashups such as data and network security [39]. CA, USA: USENIX Association Berkeley; 2005:227–229.

From the perspective of the application development, developers face the complexity of building secure applications that may be hosted in the cloud. Security problems of PaaS clouds are explored and classified. The dynamic credential changes its value once a user changes its location or when he has exchanged a certain number of data packets. The authors in [77] provided some real-world cloud applications where some basic homomorphic operations are needed. Journal in Computer Virology Springer 2012, 8: 85–97. Misuse patterns describe how a misuse is performed from the point of view of the attacker. 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. As a consequence of these deep dependencies, any attack to any cloud service layer can compromise the upper layers. This report includes centralized directory, access management, identity management, role-based access control, user access certifications, privileged user and access management, separation of duties, and identity and access reporting. Thus, these images are fundamental for the the overall security of the cloud [46, 49]. Although there are many benefits to adopting Cloud Computing, there are also some significant barriers to adoption. Zhang S, Zhang S, Chen X, Huo X: Cloud Computing Research and Development Trend. In Proceedings of the 1st International conference on Cloud Computing. J Internet Serv Appl 4, 5 (2013). IBM J Res Dev 2009, 53(4):560–571. Viega J: Cloud Computing and the common Man. 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. 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. In the second model, the vendor also provides different instances of the applications for each customer, but all instances use the same application code. Largely because of the relatively lower degree of abstraction, IaaS offers greater tenant or customer control over security than do PaaS or SaaS [10]. This information can be expressed in a more detailed way using misuse patterns [62]. In Services Computing conference. One of the most significant barriers to adoption is security, followed by issues regarding compliance, privacy and legal matters [8]. Tebaa M, El Hajji S, El Ghazi A: Homomorphic encryption method applied to Cloud Computing. OWASP: The Ten most critical Web application Security risks. 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. The inclusion and exclusion criteria of this study were based on the research question. Before analyzing security challenges in Cloud Computing, we need to understand the relationships and dependencies between these cloud service models [4]. 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. We put more emphasis on threats that are associated with data being stored and processed remotely, sharing resources and the usage of virtualization. 10/16/2019; 2 minutes to read; In this article. Owens K: Securing virtual compute infrastructure in the Cloud. In Security engineering for Cloud Computing: approaches and Tools. 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]. One of the current cloud computing security issues and challenges affecting cloud security in 2020 is the problem of data breaches. Sydney, Australia: APSEC; 2010. volume 4, Article number: 5 (2013) 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]. 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. SaaS provides application services on demand such as email, conferencing software, and business applications such as ERP, CRM, and SCM [30]. In Proceedings of the 2010 International conference on Security and Management SAM’10. They concluded that HyperSafe successfully prevented all these attacks, and that the performance overhead is low. In Eleventh International conference on Mobile data Management (MDM). It also creates confusion over which service provider is responsible once an attack happens. The goal of this analysis is also to identify some existing defenses that can defeat these threats.

Virtual networks are also target for some attacks especially when communicating with remote virtual machines. Malware injections are scripts of malicious code that hackers inject into a cloud computing service. Besides secure development techniques, developers need to be educated about data legal issues as well, so that data is not stored in inappropriate locations.

Accessed: 02-Aug-2011 The Register, 08-Jun-2009. The Register, 08-Jun-2009. PaaS facilitates deployment of cloud-based applications without the cost of buying and maintaining the underlying hardware and software layers [21]. Here are some of the security issues associated to IaaS. However, it also introduces new opportunities for attackers because of the extra layer that must be secured [31]. In Second International Conference on Future Networks (ICFN’10), Sanya, Hainan, China. PaaS providers are responsible for securing the platform software stack that includes the runtime engine that runs the customer applications. The three basic operations for cloud data are transfer, store, and process. IEEE Security Privacy 2010, 8(6):40–47. Jordan: Amman; 2011:1–6. 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]. 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. In Proceedings of the 2009 ACM workshop on Cloud Computing Security. 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. Cloud Computing is a flexible, cost-effective, and proven delivery platform for providing business or consumer IT services over the Internet. - Provides ability to pool computing resources (e.g., Linux clustering). 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. Virtualization which allows multiple users to share a physical server is one of the major concerns for cloud users. Data may be stored on different places with different legal regimes that can compromise its privacy and 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]. In Cloud Computing. 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. Cloud Security Alliance: Security guidance for critical areas of focus in Cloud Computing V3.0.. 2011. The cloud model provides three types of services [21, 28, 29]: Software as a Service (SaaS). The security issues are a little different, depending on whether you use a public cloud or private cloud implementation of IaaS. In both SaaS and PaaS, data is associated with an application running in the cloud.

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. 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. Developers have to keep in mind that PaaS applications should be upgraded frequently, so they have to ensure that their application development processes are flexible enough to keep up with changes [19].

Mather T, Kumaraswamy S, Latif S: Cloud Security and Privacy. Journal of Internet Services Applications 2010, 1(1):7–18. The TC participates in the process of launching or migrating a VM, which verifies that a VM is running in a trusted platform.

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]. Understanding what vulnerabilities exist in Cloud Computing will help organizations to make the shift towards the Cloud. For instance, in threat T10, an attacker can read or tamper with the contents of the VM state files during live migration. Future Internet 2012, 4(2):469–487. Any opinions, findings, and conclusions or recommendations expressed in this material are those of the author(s) and do not necessarily reflect those of the NSF. 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 can be possible because VM migration transfer the data over network channels that are often insecure, such as the Internet. In Information Security Curriculum Development Conference, Kennesaw, Georgia. Accessed: 16-Jul-2011. Washington, DC, USA: IEEE Computer Society; 2009:1–4. In SaaS, organizational data is often processed in plaintext and stored in the cloud. Furthermore, web services are the largest implementation technology in cloud environments. Unlike physical servers, VMs have two boundaries: physical and virtual [24]. That uncertainty has consistently led information executives to state that security is their number one concern with Cloud Computing [10]. They claimed that RSA is the most recognizable algorithm, and it can be used to protect data in cloud environments. Washington, DC, USA: IEEE Computer Society; 2009:1–9.

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. There are more security issues, but it is a good start for securing web applications. Xiaopeng G, Sumei W, Xianqin C: VNSS: a Network Security sandbox for virtual Computing environment. In Proceedings of the 16th ACM conference on Computer and communications security, Chicago, Illinois, USA. Additionally, security controls and self-service entitlements offered by the PaaS platform could pose a problem if not properly configured. Also, SSL technology can be used to protect data while it is in transit. In Proceedings of the 40th annual Hawaii International conference on system sciences.

There are several security standard specifications [79] such as Security Assertion Markup Language (SAML), WS-Security, Extensible Access Control Markup (XACML), XML Digital Signature, XML Encryption, Key Management Specification (XKMS), WS-Federation, WS-Secure Conversation, WS-Security Policy and WS-Trust. %PDF-1.5 IEEE Asia-Pacific: APSCC; 2009:273–278. Additionally, it is important to understand the lifecycle of the VMs and their changes in states as they move through the environment. However, it requires a huge processing power which may impact on user response time and power consumption. NY, USA: ACM New York; 2012:305–316. © 2020 BioMed Central Ltd unless otherwise stated. With IaaS, cloud users have better control over the security compared to the other models as long there is no security hole in the virtual machine monitor [21].
