Electronic confidentiality loss takes place when the clients and servers are not encryptingtheir communications. 3.1.6 Availability: Availability ensures that data processing resources are not made unavailable by malicious action. It is the simple idea that when a user tries to accessit is available to be accessed. This is vital for mission critical systems. Availability for these systems is critical that companies have business continuity plans (BCP‟s) in order for their systems to have redundancy. 4. RELEATED WORK Although cloud service providers can provide benefitsconsumers, security risks play a major role in the cloud computing environment. Users of online data sharing or network facilities are aware of the potential loss of privacy [8]. According to a recent IDC survey [3], the top challenge for 74% of CIOs in relation to cloud computing is security. Protecting private and important information such as credit card details or patients’ medical records from attackers or malicious insiders is of critical importance [5]. Moving databases to large data enters involves many security challenges [7] such as virtualization vulnerability, accessibility vulnerability,control issues related to data accessed from party, integrity, confidentiality, and data loss or theft.[1] Present some fundamentalchallenges, which are data storage security,application security, data transmission security,security related to third-party resources. In different cloud service models, the securityresponsibility between users and providers is different. According to Amazon [8], their EC2 addresses security control in relation to physical, environmental, and virtualization security, whereas, the users remain responsible for addressing security control of the IT system including the operating systems, applications and data. According to [3], the way the responsibility for privacy and security in a cloudenvironment is shared between consumers andservice providers differs between delivery models.

SaaS, cloud providers are more responsible for thesecurity and privacy of application services than the users. This responsibility is more relevant to the public than the private cloud environment because the clients need more strict security requirements in the public cloud. In PaaS, users are responsible for taking care of the applications that they build and run on platform, while cloud providers are responsible for protecting one user’s applications from others. In IaaS, users are responsible for protecting operating systems and applications, whereas cloud providers must provide protection for the [5] claim that the levels of security issuesdifferent.

As a result, internet security problems will affect the cloud, with greater risks due to valuable resources stored within the cloud and cloud vulnerability. The technology used in the cloud is similar to the technology used in the Internet. Encryption techniques and secure protocols are not sufficient totransmission in the cloud.

For instance, any damage which occurs to the security of the physical infrastructure or any failure in relation o the management of the security of the infrastructure

TECHNIQUES TO SECURE DATA IN

Authentication and Identity- Authentication of users and even of communicating

ed by various methods, but the most common is cryptography. Authentication of



users takes place in various ways like in the form of passwords that is known individually, in the form of a security token, or in the form a measurable quantity like fingerprint. One problem with using traditional identity approaches in a cloud environment is faced when the enterprise uses multiple cloud serviceproviders (CSPs). In such a use case, synchronizing identity information with the enterprisescalable. Other problems arise with traditional identity approaches when migrating infrastructure toward a cloud-based solution. 5.2 Malware-injection attack solutionThis solution creates a no. of client virtual machines and stores all of them in a central storage.FAT (File Allocation Table) consisting of virtual operating systems. The application that is run by a client can be found in FAT table. All the instances are managed and scheduled by Hypervisor. IDT (Interrupt Descriptor Table) is used for integrity checking. 5.3 Data Encryption- If you are planning to store sensitive information on a large data store then you need to use datatechniques. Having passwords and firewalls is good, but people can bypass them to access your data. When data is encrypted it is in a form that cannot be read without an encryption key. The data is totally useless to the intruder. It is a technique of translation of datainto secret code. If you want to read the encrypted data, you should have the secret key or is also called encryption key. 5.4 Information integrity and PrivacyCloud computing provides information and resources to valid users. Resources can be accessed through web browsers and can also be accessed by malicious attackers. A convenient solution to the problem of information integrity is to provide mutual trust between provider and user. Another solution can be providing proper authentication, authorization and accounting controls so the process of accessing information should go through various multi levels ofchecking to ensure authorized use of resources. Some secured access mechanisms should be RSA certificates, SSH based tunnels. 5.5 Availability of Information (SLA) Non availability of information or data is a major issue regarding cloud computing services.Level agreement is used to provide the information about whether the network resources are available for

STANDARDS Standards for security define procedure andfor implementing a security program. Tosecure environment, that provides privacy and security some specific steps areapplying cloud related activities by these standards. A concept called “ Defence in Depthprovide security. This concept has layers of defence. In this way, if one of the systems fails, overlapping technique can be used to provide security as it has nosingle point of failure. Traditionally, endpoints have the technique to maintain security, controlled by user. 6.1 Open Authentication (OAuth)It is a method used for interacting with protected data. It is basically used to provide data accessdevelopers. Users can grant access to information to developers and consumers without identity. OAuth does not provide any security by itself in fact it depends on other protocols like SSL to provide security. 6.2 Security Assertion Markup Language

(SAML)- SAML is basically used in business deals forcommunication between online partners. Itis an XML based standard used for authentication, authorization among the partners. SAML principal (a user), a service provider (SP) and an identity provider (IDP). SAML provides queries and responses to specify user attributes authorization andauthentication information in XML format. The requesting party is an online site that receivesinformation. 6.3 SSL/TLS- TLS is used to provide secure communication over TCP/IP. TLS works in basically threephase, negotiation is done between clients to identify which ciphers are used. Inexchange algorithm is used for authentication. These key exchange algorithms are public key algorithm.

CONCLUSIONS AND FUTURE WORKOne of the biggest security worries with the cloud computing model is the sharing of resources. Cloud service providers need to inform their customers on the level of security that they provide on their cloud. In this paper, we first discussed variouscloud computing, security issues and researchchallenges in cloud computing. Data security is major issue for Cloud Computing. There are several other security challenges including security aspects of network and virtualization. This paper has highlighted all these issues of cloud computing. Wedue to the complexity of the cloud, it will be difficult to achieve end-to-end security. New securitytechniques need to be developed and older security techniques needed to be radically tweaked to be able to work with the clouds architecture. As the development of cloud computing technology is still at an early stage, we hope our work will provide a better understanding of the design challenges of cloudcomputing, and pave the way for further research in this area.
