Foundations of Attack-Defense Trees
We introduce and give formal definitions of attack–defense trees. We argue that these trees are a simple, yet powerful tool to analyze complex security and privacy problems. Our formalization is generic in the sense that it supports different semantical approaches. We present several semantics for attack–defense trees along with usage scenarios, and we show how to evaluate attributes.
متن کاملQuantitative Questions on Attack-Defense Trees
Attack–defense trees are a novel methodology for graphical security modeling and assessment. The methodology includes visual, intuitive tree models whose analysis is supported by a rigorous mathematical formalism. Both, the intuitive and the formal components of the approach can be used for quantitative analysis of attack–defense scenarios. In practice, we use intuitive questions to ask about a...
متن کاملADTool: Security Analysis with Attack-Defense Trees
The ADTool is free, open source software assisting graphical modeling and quantitative analysis of security, using attack–defense trees. The main features of the ADTool are easy creation, efficient editing, and automated bottom-up evaluation of security-relevant measures. The tool also supports the usage of attack trees, protection trees and defense trees, which are all particular instances of ...
متن کاملEvaluation of Attributes on Attack–Defense Trees
Consequently, an ADTree has nodes of two opposite types: attack nodes and defense nodes. The root of an ADTree represents the main goal of the attacker. Every node of an ADTree may have one or more children of the same type representing a refinement into sub-goals of the node’s goal. The refinement of a node can be either disjunctive or conjunctive. The goal of a disjunctively refined node is a...
