“A SAFETY DESIGN OF CLOUD STORAGE”SUBMITTED BY:1. VIJAY S SUTAR 2GI09CS1152. VISHWANATH S ATHANIKAR 2GI09CS118 UNDER THE GUIDANCE OF: Prof K.D. HANABARATTI
WHAT IS CLOUD ?Cloud computing is a model for enablingon-demand network access.DELIEVERY MODELS Software as a Service (SaaS) Platform as a Service (PaaS) Infrastructure as a Service (IaaS)
WHAT IS CLOUD STORAGE ?It is the resource storage of cloud computing.Complex system consisting of Network devices Storage devices Servers Application software Public access interfaceCloud storage is not stored, but a service.
SECURITY ISSUES Cloud computing service availability Cloud computing service reliability User data security.Eg.1. Microsofts cloud computing platform Azure had tostop running on March 17, 2009 2.salesforce.com 3.VMware
A CLOUD STORAGE ARCHITECTUREConsists of: Storage layer Basis of management Application Interface Layer Access layer
CLOUD STORAGE SECURITY DESIGNA. Cloud Storage Safety Design ModelIt consists of four parts Storage cloud Control center User interface Client.
FUNCTIONALITIES Storage encryption Backup encryption Exchange of encryption Interface security(authentication and access control)
CLOUD STORAGE KEY TECHNOLOGIES• Storage EncryptionEncrypt the user-specified directory or file and thensave.• Users must be registered to use this technology.• Registered users can voluntarily choose to use kind of encryption Symmetric cryptosystem DES algorithm Asymmetric cryptosystem, RSA algorithm
APPLICATIONS Deterrent Control Preventative Control Corrective Control Detective Control
CONCLUSION Cloud storage is rapidly developing cloud storage security issues are also facing unprecedented challenges. To use cloud storage to a wider range of applications, not just the technical issues can be resolved, but also standardization, conscious of the constraints of laws and regulations and user compliance
