A software assignment algorithm for minimizing worm damage in networked systems

摘要: Abstract Homogeneous networked systems are at high risk of being compromised by malicious attacks that exploit a single weakness common to all. Following the survivability through heterogeneity philosophy, we present novel approach improving via software diversity. In this work, propose an algorithm for assigning number packages over network in intelligent way such machines running identical isolated into small “islands”, hence restricting worm-like from propagation. While developing algorithm, take consideration not only practical constraints, including host functionality and availability, but also weight, severity impact range vulnerability, well balancing effectively minimizing potential damage attack. We introduce possible enhancements taking advantage topological features network. Finally, comparative analysis our using simulation various structures. The results confirm effectiveness scalability show its capability creating moving attack surface. level can actually create depends on ratio installed total available software.
