Querying Attack-Fault-Defense Trees: Property Specification in Smart Grid and Aerospace Case Studies
Reza Soltani, Stefano M. Nicoletti, Milan Lopuhaä-Zwakenberg +1
This paper introduces AFDL, a logic-based framework for reasoning about safety, security, and defense interactions in Attack-Fault-Defense Trees, which is a model that captures all…
An ontological lens on attack trees: Toward adequacy and interoperability
Ítalo Oliveira, Stefano M. Nicoletti, Gal Engelberg +3
Attack Trees (AT) are a popular formalism for security analysis. They are meant to display an attacker's goal decomposed into attack steps needed to achieve it and compute certain…
BayesL: a Logical Framework for the Verification of Bayesian Networks
Stefano M. Nicoletti, E. Moritz Hahn, Mariëlle Stoelinga
Modern explainable AI still struggles with a fundamental gap: although Bayesian networks (BNs) provide transparent probabilistic structure, there is no unified way to formally expr…
WATCHDOG: an ontology-aWare risk AssessmenT approaCH via object-oriented DisruptiOn Graphs
Stefano M. Nicoletti, E. Moritz Hahn, Mattia Fumagalli +2
When considering risky events or actions, we must not downplay the role of involved objects: a charged battery in our phone averts the risk of being stranded in the desert after a…
How hard can it be? Quantifying MITRE attack campaigns with attack trees and cATM logic
Stefano M. Nicoletti, Milan Lopuhaä-Zwakenberg, Mariëlle Stoelinga +2
The landscape of cyber threats grows more complex by the day. Advanced Persistent Threats carry out attack campaigns - e.g. operations Dream Job, Wocao, and WannaCry - against whic…
Querying Fault and Attack Trees: Property Specification on a Water Network
Stefano M. Nicoletti, Milan Lopuhaä-Zwakenberg, E. Moritz Hahn +1
We provide an overview of three different query languages whose objective is to specify properties on the highly popular formalisms of fault trees (FTs) and attack trees (ATs). The…
Considerations on Approaches and Metrics in Automated Theorem Generation/Finding in Geometry
Pedro Quaresma, Pierluigi Graziani, Stefano M. Nicoletti
The pursue of what are properties that can be identified to permit an automated reasoning program to generate and find new and interesting theorems is an interesting research goal…
ATM: a Logic for Quantitative Security Properties on Attack Trees
Stefano M. Nicoletti, Milan Lopuhaä-Zwakenberg, E. Moritz Hahn +1
Critical infrastructure systems - for which high reliability and availability are paramount - must operate securely. Attack trees (ATs) are hierarchical diagrams that offer a flexi…
PFL: a Probabilistic Logic for Fault Trees
Stefano M. Nicoletti, Milan Lopuhaä-Zwakenberg, E. Moritz Hahn +1
Safety-critical infrastructures must operate in a safe and reliable way. Fault tree analysis is a widespread method used for risk assessment of these systems: fault trees (FTs) are…
BFL: a Logic to Reason about Fault Trees
Stefano M. Nicoletti, E. Moritz Hahn, Marielle Stoelinga
Safety-critical infrastructures must operate safely and reliably. Fault tree analysis is a widespread method used to assess risks in these systems: fault trees (FTs) are required -…
Model-based Joint Analysis of Safety and Security: Survey and Identification of Gaps
Stefano M. Nicoletti, Marijn Peppelman, Christina Kolb +1
We survey the state-of-the-art on model-based formalisms for safety and security joint analysis, where safety refers to the absence of unintended failures, and security to absence…
