Research for security strategy of cloud service based on system survivability

Along with the ragingly increasing concern about cloud computing due to its appalling potential merits, not only do we envision its blossom prospect, but we also realize that the importance and the major traits of system survivability in cloud computing. Therefore, this paper firstly discusses the basic concept and main characteristics of cloud computing. And in sequence it summarizes the definition and strategies of system survivability in traditional secure engineering. What is more important is that, basing on the analysis system survivability in such nascent progressing trend, this paper proposes certain security strategies and model of cloud service in order to maintain and propel system survivability in cloud computing.
