Proc.】Proceedings of 2012 IEEE 3rd International Conference on Software Engineering and Service Science（ICSESS 2012） 【Conference host】IEEE Beijing Section、Beijing University of Technology Abstract The concept of cloud computing is a very vast concept which is very efficient and effective security services.The cloud computing methodology is a conceptual based technology which is used widely nowadays. But in data privacy protection and data retrieval control is one of the most challenging research work in cloud computing, because of users secrete data which is to be stored by user. An enterprise usually store data in internal storage and then tries to protect the data from other outside source. They also provide authentication at certain specific level. Cloud computing offers an innovative business model for organizations to adopt IT services without upfront investment. Despite the potential gains achieved from the cloud computing, the organizations are slow in accepting it due to security issues and challenges associated with it. Security is one of the major issues which hamper the growth of cloud.The idea of handing over important data to another company is worrisome; such that the consumers need to be vigilant in understanding the risks of data breaches in this new environment. This paper introduces a detailed analysis of the cloud computing security issues and challenges focusing on the cloud computing types and the service delivery types. This paper mainly proposes the core concept of secured cloud computing. It suggests the cloud computing based on separate encryption and decryption services from the storage service.Due to this increasing demand for more clouds there is an ever growing threat of security becoming a major issue. This paper shall look at ways in which security threats can be a danger to cloud computing and how they can be avoided.

I NTRODUCTION Cloud computing is has many technologies such as Saas i.e. “Software as a Service”, Paas i.e. “Platform as a Service”, IaaS i.e. Infrastructure as a Service”. Cloud Computing is a paradigm that focuses on sharing data and computations over a scalable network of nodes. Examples of such nodes include end user computers,data centers, and Cloud Services. We term such a network of nodes as a Cloud. Cloud Service Models:Cloud Software as a Service (SaaS);Cloud Platform as a Service (PaaS);Cloud Infrastructure as a Service (IaaS). Cloud Deployment Models:Private Cloud;Community Cloud;Hybrid Cloud. Method II.CLOUD SECURITY 1.Service Provider Security Issues. The public cloud computing surroundings offered by the cloud supplier and make sure that a cloud computing resolution satisfies organizational security and privacy needs. The cloud supplier to provision the safety controls necessary to safeguard the organization’s information and applications, and additionally the proof provided regarding the effectiveness of these controls migrating organizational information and functions into the cloud. Mainly include 4 parts:Identity and access management; Privacy;Securing Data in Transmission;User Identity;Audit and Compliance. 2.Infrastructure Security Issues Cloud suppliers provide security-related services to a good vary of client types; the security equipped to the foremost demanding clients is additionally created on the market to those with the smallest amount stringent necessities.Whereas Infrastructure Security Solutions and product are often simply deployed, they need to a part of an entire and secure design to be effective.Securing Data-Storage;Network and Server; 3.End User Security Issues End Users need to access resources within the cloud and may bear in mind of access agreements like acceptable use or conflict of interest. The client organization have some mechanism to find vulnerable code or protocols at entry points like servers, firewalls, or mobile devices and upload patches on the native systems as soon as they are found. III.LIMITATIONS OF CLOUD COMPUTING Data losses / leakage Cloud computing efforts to control the security of the data is not very better; 本文来源：https://www.wddqw.com/doc/6b84c66f866fb84ae55c8d6c.html
