We discuss procedures that help verify the IUT's detection and prevention accuracy, attack coverage and behavior under diverse traffic patterns. We conclude by discussing the implications of our findings for the design of future distributed applications, the likely influence of other factors and of extreme parameter values on the ability of the system to self-organize and the potential improvements to our framework. Scalability issues with respect to the key parameters of system size and diversity are extensively discussed.. We propose algorithms to partition attacker/victim-emanated packets so that they are subjected to security inspections by the IUT and in addition, we offer packet manipulation operations to shape replayed traces. Finally, we introduce dynamic goals by making the preferred neighbour type a function of the local characteristics of a simulated workload.Intrusion prevention systems (IPSs) not only attempt to detect attacks but also block malicious traffic and pro-actively tear down pertinent network connections. Finally, we evaluate the strengths of our framework by mainly examining the open-source IPS Snort-Inline. The outcome of this is a Pareto front of optimal strategies, all of which would satisfy the objectives. This dual mode renders the design/implementation and more importantly the testing of IPSs a challenge.Genetic Algorithms may be used together with Pareto Optimality in the process of selection of an optimal strategy by taking into account this distribution alongside user preferences, video content characteristics and usage history. Furthermore, the send-and-receive mechanism of our engine allows for the correlation of engine-replayed and IUT-forwarded packets as well as the verification of IUT actions on detected attacks. Conflicting goals are introduced, in the form of a population of nodes actively seeking to acquire neighbours of a type different from their own, resulting in decreased local homogeneity. In
