A Formal Framework for Patch Management

Abstract

A patch management model provides a framework with which a system’s parameters and behavior can be tested and validated. The authors propose a formal framework that is based on the Continuous Time Markov Chain Model and validate the model using the SHARPE modeling tool. Furthermore, they perform sensitivity analyses to study the dynamic behavior of the proposed model with varying parameter values. A discussion on the results of our study and future research directions concludes the paper.
