“…That is an argument with a strict TopRule can rebut an argument with a defeasible TopRule, but not vice versa. ( [4] and [10] introduce the ASPIC-and ASPIC + D systems which use unrestricted rebut). Finally, A set of arguments is said to be consistent iff there is no attack between any arguments in the set.…”

In this paper we investigate the links between instantiated argumentation systems and the axioms for nonmonotonic reasoning described in [9] with the aim of characterising the nature of argument based reasoning. In doing so, we consider two possible interpretations of the consequence relation, and describe which axioms are met by ASPIC + under each of these interpretations. We then consider the links between these axioms and the rationality postulates. Our results indicate that argument based reasoning as characterised by ASPIC + isaccording to the axioms of [9] -non-cumulative and non-monotonic, and therefore weaker than the weakest non-monotonic reasoning systems they considered possible. This weakness underpins ASPIC + 's success in modelling other reasoning systems, and we conclude by considering the relationship between ASPIC + and other weak logical systems. 1 ASPIC + was selected for this study due to its popularity, and its ability to model a variety of other structured systems [13].

“…The canonical example here comes from[45] via[36], and is the rule that normally objects that appear red, are red. However, in the situation that everything is illuminated with red light, this rule no longer holds since under red light everything, including things that are not red, will appear to be red.3 This asymmetry is not uncontroversial, see[11,33] for arguments against it.…”

“…The model of structured argumentation that we use in the following examples is that of [28], which is a defeasible subset of ASPIC+ [33]. In terms of the element introduced above, L contains a set of propositions p i , their negations ¬p i , and a set of defeasible rules p 1 , .…”

Abstract. Firewalls are an important tool in the assurance of network security. Packet filtering firewalls are configured by providing a set of rules that identify how to handle individual data packets that arrive at the firewall. In large firewall configurations, conflicts may arise between these rules. Argumentation provides a way of handling conflicts such that their origin is illuminated, and hence can help a system administrator understand the effects of a given configuration. To show how argumentation might help in this domain we examine the use of a system of metalevel argumentation for firewall configuration, showing how it makes conflicts and their origins clear, and showing how different instantiations of a metalevel argumentation system provide alternative ways to resolve conflicts.
