Abstract: The research of survivability analysis for information system is summarized and discussed. Survivability definition for information system is reviewed; survivability analysis model is classified into system architecture or system service based model; means of analysis is classified into true or simulating system based method; and quantitatively analysis is classified into physical or logical parameter based analysis. Problems in these four fields are discussed and the future research directions are given.

Key words: Survivability; Information system; Quantitatively analysis
