Inside the ongoing decade, significant developments in technology have arisen that possibly add more accommodation to everyday life rehearses on an enterprise-level as well as on a singular level also. Cloud Computing technology has seen huge advances in its execution and becomes broadly received by one or the other private or public areas. It was clear as of late that many associations and enterprises are moving their outstanding tasks at hand to the cloud. In any case, Security is a significant worry for the cloud computing administrations, which depends on the Internet association that makes it powerless against numerous kinds of attacks. Despite the fact that that the security estimates executed over cloud computing are building up each spending year, Security still a test. In this paper, we led a review concentrate on cloud computing and tended to various kinds of attacks and potential dangers to this arising technology, just as assurance strategies and existing answers for such attacks.

p>Cloud computing provides many services to access them dynamically over the internet as per the user's demand. The data is growing in tremendous amount and it should be managed correctly where storage service proves efficient. The Data stored online can be hacked by the third party so to secure this data verifying integrity is essential. Because of the human error or natural disaster, the data may get deleted from the cloud servers. Therefore, there is a requirement of improving the existing algorithm to recover data efficiently. Many algorithms are proposed, but they lack in efficiency, computational cost, and reliability. The proposed system in this paper is having the feature of verifying data integrity using Identity Based Remote Data Integrity Checking and recovery using the XOR operation. When the data is unavailable to the user, the proposed system provides flexibility for the user to regain data from the remote server.</p

Cloud services help individuals and organization to use data that are managed by third parties or another person at remote locations. With the increase in the development of cloud computing environment, the security has become the major concern that has been raised more consistently in order to move data and applications to the cloud as individuals do not trust the third party cloud computing providers with their private and most sensitive data and information. This paper presents, the migration of virtual machine to improve the security in cloud computing. Virtual machine (VM) is an emulation of a particular computer system. In cloud computing, virtual machine migration is a useful tool for migrating operating system instances across multiple physical machines. It is used to load balancing, fault management, low-level system maintenance and reduce energy consumption. Virtual machine (VM) migration is a powerful management technique that gives data center operators the ability to adapt the placement of VMs in order to better satisfy performance objectives, improve resource utilization and communication locality, achieve fault tolerance, reduce energy consumption, and facilitate system maintenance activities. In the migration based security approach, proposed the placement of VMs can make enormous difference in terms of security levels. On the bases of survivability analysis of VMs and Discrete Time Markov Chain (DTMC) analysis, we design an algorithm that generates a secure placement arrangement that the guest VMs can moves before succeeds the attack.

The word “Cloud” refers to network or internet. It is present at.remote location. Cloud computing is a latest mechanism used now-a-days for accessing, manipulating and configuring applications online via internet.
It allows users for online data storage, various applications and infrastructure. There are few downsides of cloud computing like in public cloud sharing of data, selected data shared with users of various level without confidentiality and privacy of data. Different methods were used to fix this problem like encryption of attribute; encryption of access control but they have their own problems related to big computation for accquiring access structure, invoking and behavior management. So for removing these weakness, the combination of fuzzy-set theory and RSA algorithm has been introduced. Fuzzy-set is used for clustering the data based on their points. Further for privacy, I have included RSA for encryption and decryption of data which is used to store in cloud database. The analysis of my experiment shows the system is efficient, flexible and provides confidentiality of the data.

This is the era of Cloud Computing which shares on-demand computing resources and disposes off efficiently. It has a wide range of benefits for business and consumers. In spite of several benefits, there embeds numerous challenges such as data integrity, authenticity, data security, data locking, access control, data confidentiality, auditability, trust on cloud service provider, well management of service level agreement (SLA). Trust – is a key differentiator in defining the success or failure of many business companies. Service Level Agreement builds trust between cloud providers and cloud consumers. This research proposes a secured trust SLA model that builds trust on cloud service provider and helps in providing data security, confidentiality and integrity for cloud user.

In cloud computing resources are considered as services hence utilization of the resources in an efficient way is done by using task scheduling and load balancing. Quality of service is an important factor to measure the trustiness of the cloud. Using quality of service in task scheduling will address the problems of security in cloud computing. This paper studied quality of service based task scheduling algorithms and the parameters used for scheduling. By comparing the results the efficiency of the algorithm is measured and limitations are given. We can improve the efficiency of the quality of service based task scheduling algorithms by considering these factors arriving time of the task, time taken by the task to execute on the resource and the cost in use for the communication.
