Multi-Layer Information Security Framework for Software – as –a- service Platform- as – a –Service and Infrastructureas-a- Service of Cloud Computing Model

Abstract

Cloud computing increased a widespread recognition as paradigm of computing. The main objective is to reduce the need for customers' security in new hardware or software by proposing flexible cloud services, with a usage customer gaining the advantages of the pay per use approach. Various security and confidentiality issues: both problems (vulnerabilities, threats, and attacks) are the pressing demand of cloud computing to find solutions (controls). We have discussed the security issues and authorization of cloud computing, customer and their privacy. Understanding number of vulnerabilities, threats, and attacks and identifying controls for these problems. We have proposed a Multilevel and multifactor Information security framework for cloud computing users with the use of cryptography techniques to guarantee the security and authorizations of the customer and data in cloud situation.
