Abstract
N-version programming has been shown to be an effective way to increase the reliability of systems. In this technical report, we examine the possibility of etending this approach to address security, rather than reliability concerns. We focus specifically on how to evaluate the efficiency of the use of diversity for security. We show that while several key elements must be taken into account when N-version programming is used for security rather than reliability, it is nonetheless possible to devise a reasoning framework to evaluate the efficiency of this development paradigm in a security context. Furthermore, we present preliminary empirical results indicating that an effective diversity-based intrustion detection scheme is feasible.
