The studies analyze the risks and threats, often give recommendations on how they can be avoided or covered, resulting in a direct relationship between vulnerability or threats and possible solutions and mechanisms to solve them.

This analysis offers a brief description of the vulnerabilities, and indicates what cloud service models (SPI) can be affected by them. In Proceedings of the 3rd ACM workshop on Cloud Computing Security workshop. They concluded that HyperSafe successfully prevented all these attacks, and that the performance overhead is low. Malware injections are scripts of malicious code that hackers inject into a cloud computing service. Understanding what vulnerabilities exist in Cloud Computing will help organizations to make the shift towards the Cloud. Accessed: 16-Jul-2011. In conclusion, there is less material in the literature about security issues in PaaS. Ormandy T: An empirical study into the Security exposure to hosts of hostile virtualized environments. Moreover, most compliance standards do not envision compliance with regulations in a world of Cloud Computing . 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 . In IEEE International conference on Cloud Computing (CLOUD’09). As a result, security is sometimes inconsistent, and can be seen as a barrier to moving applications to the cloud. Cloud computing security issues and challenges 1. 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. Cloud Computing leverages many existing technologies such as web services, web browsers, and virtualization, which contributes to the evolution of cloud environments. In this paper we are going to some major security issues of current cloud computing environments. By using this website, you agree to our One of the current cloud computing security issues and challenges affecting cloud security in 2020 is the problem of data breaches. This set of relevant studies was again filtered with the exclusion criteria to give a set of studies which corresponds with 15 primary proposals [4, 6, 10, 16–27]. 3 0 obj Hashizume K, Yoshioka N, Fernandez EB: Three misuse patterns for Cloud Computing. In Proceedings of the 40th annual Hawaii International conference on system sciences. Web applications can be an easy target because they are exposed to the public including potential attackers. In Proceedings of the Joint ERCIM Workshop on Software Evolution (EVOL) and International Workshop on Principles of Software Evolution (IWPSE), Antwerp, Belgium. This work was supported in part by the NSF (grants OISE-0730065). The NIST Cloud Computing Standards Roadmap Working Group has gathered high level standards that are relevant for Cloud Computing. Data may be stored on different places with different legal regimes that can compromise its privacy and security. 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. 10.1016/j.future.2010.12.006. 2010. VMs can be on, off, or suspended which makes it harder to detect malware. IEEE Computer Society Washington DC, USA; 2010:344–349. 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. PALM  proposes a secure migration system that provides VM live migration capabilities under the condition that a VMM-protected system is present and active. PaaS application security comprises two software layers: Security of the PaaS platform itself (i.e., runtime engine), and Security of customer applications deployed on a PaaS platform . In Second International Conference on Future Networks (ICFN’10), Sanya, Hainan, China. The RMF is your best bet for resolving security control issues on the PaaS. Future Internet 2012, 4(2):469–487. Moreover,  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. Largely because of the relatively lower degree of abstraction, IaaS offers greater tenant or customer control over security than do PaaS or SaaS .

In National Days of Network Security and Systems (JNS2). Virtual machine security becomes as important as physical machine security, and any flaw in either one may affect the other . Moreover, virtualization introduces the ability to migrate virtual machines between physical servers for fault tolerance, load balancing or maintenance [16, 46]. Rev. IEEE Security Privacy 2011, 9(2):50–57. In Proceedings of the 16th ACM conference on Computer and communications security, Chicago, Illinois, USA. Thus, these images are fundamental for the the overall security of the cloud [46, 49]. 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. endobj PaaS providers are responsible for securing the platform software stack that includes the runtime engine that runs the customer applications. In Trusted Infrastructure Technologies Conference, 2008. 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. Resolving such problems may increase the usage of cloud thereby reducing the amount spent for resources. In , they propose a method based on the application of fully homomorphic encryption to the security of clouds.

In SaaS, organizational data is often processed in plaintext and stored in the cloud.  this technique aims to provide intrusion tolerance and, in consequence, secure storage. 2009. 2009. In Proceedings of the 4th Int. Virtual networks are also target for some attacks especially when communicating with remote virtual machines. 10.1007/s13174-010-0007-6. Washington, DC, USA: IEEE Computer Society; 2010:380–395. 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. In Cloud Computing: principles, systems & applications. The cloud model provides three types of services [21, 28, 29]: Software as a Service (SaaS). Fong E, Okun V: Web application scanners: definitions and functions. Some of these vulnerabilities are the following: Lack of employee screening and poor hiring practices  – some cloud providers may not perform background screening of their employees or providers. Online. In International Conference on Computer Application and System Modeling (ICCASM), vol. SSL is the underpinnings of most of the "security" utilized in the cloud and, for that matter, the Internet in general.

Jasti A, Shah P, Nagaraj R, Pendse R: Security in multi-tenancy cloud. 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.
