Threat Analysis and Attacks on XtreemOS: a Grid-enabled Operating System

We perform a preliminary threat analysis on a grid-enabled operating system, namely XtreemOS, in this paper. While currently under development, XtreemOS aims to provide native Virtual Organisation support in a secure and dependable manner. We investigate security within the XtreemOS architecture by identifying the security requirements and objectives. Further, we list assets within the system that need protection and detail attacks using the attacker tree methodology. At the end, we describe a specific attack on the overall XtreemOS-supported architecture using an attacker tree. Analysis of this nature will help in generating a number of test cases for testing an early prototype of XtreemOS and provide assurance to the security of the XtreemOS system.
