Insider threat modeling: An adversarial risk analysis approach
Chaitanya Joshi, David Rios Insua, Jesus Rios
Insider threats entail major security issues in geopolitics, cyber risk management and business organization. The game theoretic models proposed so far do not take into account som…
Protecting from Malware Obfuscation Attacks through Adversarial Risk Analysis
Alberto Redondo, David Rios Insua
Malware constitutes a major global risk affecting millions of users each year. Standard algorithms in detection systems perform insufficiently when dealing with malware passed thro…
Augmented Probability Simulation Methods for Sequential Games
Tahir Ekin, Roi Naveiro, Alberto Torres-Barrán +1
We present a robust framework with computational algorithms to support decision makers in sequential games. Our framework includes methods to solve games with complete information,…
Variationally Inferred Sampling Through a Refined Bound for Probabilistic Programs
Victor Gallego, David Rios Insua
A framework to boost the efficiency of Bayesian inference in probabilistic programs is introduced by embedding a sampler inside a variational posterior approximation. We call it th…
Opponent Aware Reinforcement Learning
Victor Gallego, Roi Naveiro, David Rios Insua +1
In certain reinforcement learning (RL) scenarios there are adversaries trying to interfere with the underlying reward process for their own benefit. We introduce Threatened Markov…
An Adversarial Risk Analysis Framework for Cybersecurity
David Rios Insua, Aitor Couce Vieira, Jose Antonio Rubio +3
Cyber threats affect all kinds of organisations. Risk analysis is an essential methodology for cybersecurity as it allows organisations to deal with the cyber threats potentially a…
