Based On Cloud Computing SaaS Model For Information Security Research

As cloud computing is used by more and more enterprises, especially for that small and medium-sized enterprises.As to save hardware and maintenance costs,they are Embracing the SaaS model deployment for enterprise applications. While they are a lot of safety factor in it. The potential safety hazard exists not only in SaaS provider.At the same time also in the enterprise application and SaaS cloud all aspects in the process of communication, thus SaaS services security problems is imminent.Then there are many factors influence the cloud-based SaaS services in information security aspect.So forecasting the unsafety factors is very difficult, especially for that business users can safely storage of key information or not, whether can secure transport is the key factors influencing the enterprises to adopt SaaS services. So information security research based on SaaS Service has always been a hot research problem.In this article, through the main performance of the security risks,we can analyze the information security that occured in cloud computing mode. Aiming at application in SaaS mode of safety defects, from the incident response, notices and remedy, data center operation security, establish the related security mode.Through the trust model, the data transmission and storage of information security ultimately is the key fators. And based on the mechanism of public key encryption architecture and the realization of the core, set up information security encryption logic architecture and regularly update the key to guarantee the safety of key information can be very safe.
