Parametric Analyses of Attack-Fault Trees [PDF]

2019 19th International Conference on Application of Concurrency to System Design (ACSD), 2019
Risk assessment of cyber-physical systems, such as power plants, connected devices and IT-infrastructures has always been challenging: safety (i. e., absence of unintentional failures) and security (i. e., no disruptions due to attackers) are conditions that must be guaranteed.

Some Security Issues with the Industrial Internet of Things and Comparison to SCADA Systems

Информатика и автоматизация, 2020
An issue of the Internet of Things security which does not belong to the traditional problem of cybersecurity, as it is a local or distributed monitoring and/or monitoring of physical systems state connected via the Internet, is considered.

Attack-defense trees

Journal of Logic and Computation, 2012
Attack-defense trees are a novel methodology for graphical security modelling and assessment. They extend the well- known formalism of attack trees by allowing nodes that represent defensive measures to appear at any level of the tree. This enlarges the modelling capabilities of attack trees and makes the new formalism suitable for representing ...

Attack-Tree Series: A Case for Dynamic Attack Tree Analysis [PDF]

, 2019
Attack trees are a popular model for security scenario analysis. Yet, they are currently treated in the literature as a static model and are not suitable for dynamic security monitoring. In this paper we introduce attack-tree series, a time-indexed set of attack trees, as a model to capture and visualize the evolution of security scenarios.

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

Foundations of Attack–Defense Trees [PDF]

, 2011
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

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 ...

Probabilistic modeling and analysis of sequential cyber‐attacks

Engineering Reports, 2019
Security is one of the major challenges for promoting the computer industry. Existing models for assessing security have mostly assumed that different hazards causing the security breach are independent of each other. Dependencies however can exist among
