The main objective of the research is to conduct an analysis of the framework for alternate execution of workflows under intrusion threat with respect to different types of threats. Framework for alternate execution of workflows under threat makes the system available to the end user no matter if it is under attack by some intrusion threat. The assessment is required to be made for the framework in consideration in terms of what types of threats and how many types of threats for which it may work. For this purpose, 34 different types of threats as described by SOPHOS have been considered. Firstly the types of threats have been categorized based on their goals. Then for each category, framework in consideration is assessed. On the basis of that assessment it is analyzed for what types of threats, the framework can be enabled completely and partially. The number of threats for which the framework is enabled completely is also found. Based on the analysis, the recommendations have been made for possible extensions in the framework where it is enabled partially. © 2011 Springer-Verlag.
