Providing Availability on the Poly^2 Framework

Chakraborty, Ankur. M.S., Purdue University, May, 2010. Providing Availability on the Poly^2 Framework. Major Professor: Eugene Spafford, Melissa Dark. Availability is not often a primary concern for frameworks meant to provide security. Poly^2 is one such framework. It provides us with a hardened foundation based on secure design principles to run mission-critical services. While, the primary focus of Poly^2 till now seems to have been fault isolation, we will now attempt to add recovery as well. However, current techniques may compromise the security principles on which the framework was originally built. We propose a hybrid system based on two popular techniques to rectify the same.
