At the start of each operation the hash, of the VM snapshot is calculated over its registers, memory contents, and image disk. The proposed framework also introduced the host based firewall and intrusion detection system. Additionally, the ACPS also provides auditability for the actions of VMs. However, data security is still a major concern and is the main obstacle preventing cloud computing from being more widely adopted. Vasilakos, A survey on trust management for Internet of things, J. Netw. The data and index are sent to the cloud, where they are stored depending on the SR value. applicable we explain our solutions in the context of Haizea. The restrictions are specific to the situations where data is to be shared among the group and/or requires forwarding. All of the users whether individual or organization should be well aware of the security, threats existing in the cloud. The homomorphic token are pre-computed by the user and data, is fragmented and stored redundantly across the cloud servers. The SPICE exploits the concept of group signature and randomization for providing the, anonymous authentication (to prove user authenticity without revealing identity), delegatable authentication, unlinkability, (CSPs are unable to link the transactions of the same user), accountability, and user centric access control.

Jaatun, Beyond lightning: a survey on security challenges in cloud computing, Comput. The encryption and decryption on disk and network I/O is also performed by the VM-shim. The out of control cost of power in terms of electricity generation, personnel hardware and limited spaces in data centers have encouraged a significant number of enterprises to move more infrastructures into a third party provided Cloud. The inclusion of RT along with BF for secure data deduplication shows the novelty of the paper. One of the important characteristics, of cloud applications is that they are not bonded with specific users, possibly at the same time. A security and privacy framework for RFID in cloud computing was proposed for RFID technology integrated to the cloud computing , which will combine the cloud computing with the Internet of Things. 647–651. The discussed approaches are proposed to counter either one or multiple security issues. (VMI) technique. and with the limited instruction set. The credential generation can be offloaded to a trusted third party due, to low processing power of the mobile device, Due to low processing power of mobile devices, computation intensive encryption algorithms with large keys are not, trusted third party for securing the user data, The discussion on the security issues presented in the preceding sections elaborates that the cloud not only retains the, orthodox security concerns but also entails the novel issues arising due to the use of new technologies and practices. The integrity of CloudVisor is also ensured using Trusted Platform, The encryption and integrity checks have also been used in, cloud environment. The aim of this paper is to do research on security in Cloud Computing by authenticating a Blob by some secure algorithm like HMAC for an account [12].

Vasilakos, Security and privacy for storage and computation in cloud computing, Inform. The SaaS applications are built and deployed over the PaaS and the PaaS is dependent on the underlying IaaS. Based on a core set of features in the three common cloud services – Infrastructure as a Service (IaaS), Platform as a Service (PaaS) and Software as a Service (SaaS), we identify a set of security capabilities needed to exercise those features and the cryptographic operations they entail. Adetunmbi, O.S. Multi-tenancy results in optimal use of resources and different customers are segregated, The NIST divides the services provided by the cloud computing into three categories, namely: (a) software as a service, (SaaS), (b) platform as a service (PaaS), and (c) infrastructure as a service (IaaS). Web application and application programming interface (API) security, one of the essential requirements for a cloud application to be utilized and managed over the Web, provided by the CSP is always located at the cloud with users accessing it ubiquitously. The attestation and integrity verification ensure that the VM is not migrated to a com-, hopping and useless migrations. , the source IP can be at root with the destination IP at leaf nodes. The aforesaid problems are related to the service level agreement (SLA). In case of successful update, other VMs of that particular class. A, CloudVisor also monitors the address translation to enforce memory isolation. Nevertheless, virtualization also introduces security challenges to. The, . The access control in the proposed platform is based on the OAuth (Open Authorization) that is token based access con-, trol mechanism. Based on the security requirements and attacks against cloud computing, we systematically summarize the current security protection mechanisms and further make a comparison among them.

It refers to a broad set of policies, technologies, and controls Elliptical curve cryptography (ECC) is a public key encryption technique based on elliptic curve theory that can be used to create faster, smaller, and more efficient cryptographic keys. This document, the Cloud Computing Security Requirements Guide (SRG), documents cloud security requirements in a construct similar to other SRGs published by DISA for the DoD. Our survey differs significantly from the aforesaid surveys in terms of its extensiveness, comprehensive, discussion on security issues in cloud computing, and emphasizes on latest security solutions presented in the, also provide the tabulated comparisons of the presented techniques. Key to the successful adoption and transition of information systems to cloud is the implementation of a strategic proactive information security management and governance The VM migration is a crucial phase and needs to be carried out in a secured manner, feature provides flexibility to the user. Besides checking at the registration time, the update check-, er is invoked periodically to scan the VMs. 2 (3) (2014) 320–332, [38] M.L. The SLA is a document that specifies the terms and conditions between the user and CSP. A regular data backup is, , services and applications to the cloud users are provided through the Internet, . The hypervisor checks the integrity of the DomU state after every management function, executed by the Dom0. The algorithm is capable of negotiating cloud federations to lower the risk. The user application is then registered with the security providing clouds that provide security services. The data encryption key is protected with the HASBE using the access, key structure that specifies the access control policies and attributes. Fears over cloud security persist with hackers obtaining user infor… The cloud module is not used just to store the data, but also to process them on cloud premises. To enter the cloud, a user has to pass through identity manage-, ment module that identifies the user on the basis of registered identity credentials. Security and privacy for the multi tenancy is one of the, grave challenge for the cloud computing. Each channel is assigned a unique logical ID that is used to monitor the source of packets originating from. The cloud computes the response and sends back to the user where decision, is made based on the comparison of received result with the pre-computed tokens. The generated OS view is used by the defense modules of the CloudSec. The extended template also integrates the elements that quantify the risks of using specific cloud services. All such packets are discarded. The configurations need to be well in, place not only at the time of cloud infrastructure development, deployment, and operations but subsequent changes in the, cloud network should also keep the configuration consistent with the security policies, misconfiguration occur when administrators select such a configuration tool that they are familiar with but not necessarily, changes in traffic patterns, and topology can generate the requirement of varied security policies, the configuration of the cloud should dynamically be managed to ensure the security of the cloud. Most business organizations are currently using cloud to handle multitudes of business operations. The employed approach includes security parameters in the SLA to let the end user judge the security offerings and require-. The modules that require little or no interaction with the OS are moved to. The geographical spread of cloud computing, introduces various legal issues pertaining to users’ assets and the laws under which they are governed. The National Institute of Standards and Technology’s (NIST) definition, of: (a) essential characteristics, (b) service models, and (c) deployment models. However, there are a variety of information security risks that need to be carefully considered. This has led to a major security dispute on data handling. Identity management and access control, Access control and identity management in cloud environment is highly needed to make the cloud computing adopted by, the community, according to CSA. All of the participating clouds retain. The user registers with a trusted party called, the registrar and obtains a single credential for all the services provided by the CSP. assurance and auditing tool to ensure policy acquiescence among different involved entities are direly needed. a single VM of the class and the image of update is created alongside. tication, respectively. The data in the cloud is much more vulnerable to risks in, terms of confidentiality, integrity, and availability in comparison to the conventional computing model, increasing number of users and applications leads to enhanced security risks. Comparison of strategies proposed for security of cloud applications and APIs. The proposed framework, called Kororā, is designed and developed on a public infrastructure-as-a-service cloud-computing environment. The experimental results denoted that under the file size of 8 MB, the SDD-RT-BF model offers maximum deduplication rate of 25.40% whereas the SS, SSIMI and SDM models attains minimum deduplication rate of 24.60%, 23.60% and 22.30% respectively. The data is transmitted between VMs in peer-to-peer (P2P) manner, without transiting through the central server. Aved, A. Hadiks, D. Shen, G. Chen, Information fusion in a cloud computing era: a systems-level perspective, IEEE, B. Liu, J. Bi, A. Vasilakos, Towards incentivizing anti-spoofing deployment, IEEE Trans. The larger the code, the greater the, number of points, that can be used to attack the hypervisor. Public cloud solutions are seen as the most vulnerable options from a security perspective, leaving many federal customers to seek private alternatives to overcome security challenges. The vTPM, is also migrated along with the VM to ensure the integrity of the VM during the migration process. A, VMM may affect the execution of VMs running on the host system, are managed by the victim VMM under attacker’s control, exposed to an attacker if the attacker takes control of a VMM, entry points and interconnection complexities, control of the VMM or bypass security restrictions. The DeHype greatly reduces the risk of system subversion as most, of the hypervisor code does not have privileges. Identity management and access control, In a cloud environment, the confidentiality and integrity of data and services is also linked with the identity management, and access control. The resources are provided to the users and released based on demands from the pool of shared resources, . The discussion of, the presented technique has led ways to highlight some open issues to motivate the research community and academia to, This research was in part supported by a grant from the National Science Foundation, CNS. The contributions of this survey with respect, to the aforesaid surveys are presented in, The remainder of the paper is organized as follows. secure the data in the cloud. to lack of administrative control of owner organization. This proposed cloud offers different opportunities in UAVs applications development and deployment; however, some technical challenges are present and need to be addressed before the actual benefits can be realized at a cost-effective price.

Inform. In this paper author uses improved Bayesian technique to classify the data and encrypt the sensitive data using hybrid stagnography. The Cloud System can exist situate up particularly for a firm, organization, institution. The services should have import/export function into standards such as XACML and OASIS. Waters, Efficient identity-based encryption without random oracles, in: Advances in Cryptology EUROCRYPT, Springer, Berlin, Heidelberg, 2005, pp. The NIST definition considers the cloud computing as a threefold model of service provisioning (, . Therefore the challenges, faced by the cloud due to Internet characteristic are same as the challenges of conventional IT communication, challenges include denial-of-service, man-in-the-middle, eavesdropping, IP-spoofing based flooding, and masquerading, (SSL), Internet Security Protocol (IPSec), cryptographic algorithms, intrusion detection and prevention systems, traffic clean-, not detail them in this study. For network isolation, the concept of packet rewriting is used that opens the original packet and extracts, source and destination addresses from the packet. A fundamental shift in the way Information Technology (IT) and computing services are being delivered and purchased results in the development of cloud computing. It is exceptionally important to keep track of the user’s identity and controlling unauthorized access to, due to the fact that the owner and resources are in different administrative domains and organization’s authentication and, authorization may not be exported to the cloud in the existing form, may deal with users of different organization with different authentication and authorization frameworks, at the same time, nization and cloud may give rise to complex situations over time, addresses are frequently reassigned, the services are started or re-started over shorter periods of time, pay-as-you-use, feature allows the users to join and leave cloud frequently. lation is present between different VMS, the access to same physical resources can lead to data breach and cross-VM attacks. environment, J.

Mag. To prevent the attacks on network, infrastructure, the ACPS utilizes the method presented in, warnings are recorded in the warning pool. The analysis shows that the model can complete the isolation of vTPM, and protect the security of vTPM during the migration process through the migration control server, and can strengthen the security of the virtualization platform. Moreover, the proposed sanitization process depends on the optimal key generation, which is performed by the hybrid meta-heuristic algorithm. implemented on OpenStack Glance image repository. The dependency decoupling is performed by dividing, the code of the hypervisor into smaller modules. 5 (2) (2012) 164–177, J. Che, Y. Duan, T. Zhang, J.
