Security Concern for Platform as a Service

Cloud computing provide a promising approach for computation service with fraction of cost. Many users and organization evaluates cloud's computational service based on security concern. This paper particular focuses on Security of Platform as a Service (PaaS) cloud. Security of PaaS is concerned in multiple perspectives and security issues of PaaS are discussed. To overcome the issues an algorithm, PaaS Security Concern (PaaSSC) is proposed to provide security and to guarantee SLA for PaaS cloud. The PaaSSC algorithm used to predict the probability of failure of security in the server. It comes out with probability value of secure node and hack nodes in each level. From the above calculated value, the Security measures are taken for the PaaS server and to safeguard the PaaS cloud. Index Terms- PaaS, Security Failure, Vulnerability, Privacy.
