In this smalltalk I will explain how can we improve a service’s resilience by combining diversity and replication techniques. It is realistic to assume that all software contains vulnerabilities. However, some of these vulnerabilities can be more or less critical, and can be or not discovered and exploited. In this work we assume that all the critical vulnerabilities will eventually be exploited. Said that, one wants to deploy services or applications and be ready to respond to possible attacks, in such a way that the service and application keeps executing, in a correct way, even in the presence of intrusions. By combining replication techniques with component diversity we expect to make services more resilient. Some work was done to find if there is evidence that diversity can improve replicated system’s resilience. However, we still have work to do in order to guarantee that both diversity and replication when combined improve the system’s resilience.
