A Novel Approach for Attack Tree to Attack Graph Transformation

, 2022
Attack trees and attack graphs are both common graphical threat models used by organizations to better understand possible cybersecurity threats. These models have been primarily seen as separate entities, to be used and researched in entirely different contexts, but recently there has emerged a new interest in combining the strengths of these models ...

Intelligent feature selection using particle swarm optimization algorithm with a decision tree for DDoS attack detection

IJAIN (International Journal of Advances in Intelligent Informatics), 2021
The explosive development of information technology is increasingly rising cyber-attacks. Distributed denial of service (DDoS) attack is a malicious threat to the modern cyber-security world, which causes performance disruption to the network servers. It

Attack Trees with Sequential Conjunction [PDF]

, 2015
We provide the first formal foundation of SAND attack trees which are a popular extension of the well-known attack trees. The SAND attack tree formalism increases the expressivity of attack trees by introducing the sequential conjunctive operator SAND. This operator enables the modeling of ordered events.

Attack Entropy Optimization Algorithm Based on SQAG Model [PDF]

Jisuanji gongcheng, 2020
In order to reduce network security risks and better realize the optimization of network attack paths,this paper constructs a SQAG model for network attacks based on the existing network attack graphs.The model discretizes the attack process,in which the

Attribute Decoration of Attack–Defense Trees [PDF]

International Journal of Secure Software Engineering, 2012
Attack–defense trees can be used as part of threat and risk analysis for system development and maintenance. They are an extension of attack trees with defense measures. Moreover, tree nodes can be decorated with attributes, such as probability, impact, and penalty, to increase the expressiveness of the model.

Reconstructing enzyme evolution by protein engineering

FEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Hierarchical Representation Model for APT Attack [PDF]

Jisuanji gongcheng, 2018
In view of the lack of formal representation of the theft type APT attack,a hierarchical APT representation model is built which named APT-HRM.Referring to the HARM model,the APT attacks are divided into two layers:Attack Chain(AC) and Attack Tree(AT ...

Intrapatient tumour heterogeneity and clonal evolution in an autopsy study of metastatic salivary gland cancer

Molecular Oncology, EarlyView.
Tumour heterogeneity and clonal evolution of metastatic salivary gland cancer were evaluated in two patients with adenoid carcinoma and one patient with myoepithelial carcinoma. Radiology‐guided autopsy enabled multi‐region sampling (total samples n = 149), followed by whole‐genome sequencing and phylogenetic reconstruction (17 tumour samples, 4–7 per ...
