On the Meaning and Purpose of Attack Trees [PDF]
2019 IEEE 32nd Computer Security Foundations Symposium (CSF), 2019 Attack trees are a popular notation for describing threats to systems, both in academia and industry. Originally, attack trees lacked a formal semantics, but formal semantics for different variants of attack trees were proposed later. These semantics focus on the attacker^{\prime}s actions defined in the leaves and the logical structure defined by the ...

Quantitative Model of Attacks on Distribution Automation Systems Based on CVSS and Attack Trees
Information, 2019 This study focuses on the problem of attack quantification in distribution automation systems (DASs) and proposes a quantitative model of attacks based on the common vulnerability scoring system (CVSS) and attack trees (ATs) to conduct a quantitative and

Method for Attack Tree Data Transformation and Import Into IT Risk Analysis Expert Systems
Applied Sciences, 2020 Information technology (IT) security risk analysis preventatively helps organizations in identifying their vulnerable systems or internal controls. Some researchers propose expert systems (ES) as the solution for risk analysis automation since risk ...

Attack Trees in Isabelle [PDF]
, 2018 In this paper, we present a proof theory for attack trees. Attack trees are a well established and useful model for the construction of attacks on systems since they allow a stepwise exploration of high level attacks in application scenarios. Using the expressiveness of Higher Order Logic in Isabelle, we succeed in developing a generic theory of attack

A Survey of Automatic Generation of Attack Trees and Attack Graphs
CoRR, 2023 Graphical security models constitute a well-known, user-friendly way to represent the security of a system. These kinds of models are used by security experts to identify vulnerabilities and assess the security of a system. The manual construction of these models can be tedious, especially for large enterprises.

Attack countermeasure trees (ACT): towards unifying the constructs of attack and defense trees [PDF]
Security and Communication Networks, 2011 ABSTRACTAttack tree (AT) is one of the widely used non‐state‐space models for security analysis. The basic formalism of AT does not take into account defense mechanisms. Defense trees (DTs) have been developed to investigate the effect of defense mechanisms using measures such as attack cost, security investment cost, return on attack (ROA), and return

Investigating Computer Attacks Using Attack Trees [PDF]
, 2007 System log files contain valuable evidence pertaining to computer attacks. However, the log files are often massive, and much of the information they contain is not relevant to the investigation. Furthermore, the files almost always have a flat structure, which limits the ability to query them.
