Best Paper Award für NIMBLE-Entwicklung

2017-06-23:

Für das Paper „Stackelberg Security Game for Optimizing Security of Federated IoT Platform Instances” wurde die Forscherin Violeta Damjanovic-Behrendt der Salzburg Research mit dem Best Paper Award ausgezeichnet. Präsentiert wurde das Paper Ende Mai bei der International Conference on Decision and Game Theory for Security (ICDGTS 2017) in Barcelona, Spanien.

Untersucht wurde die Verwendung des sogenannten Stackelberg Security Game (SSG) Algorithmus für die Suche nach optimalen Sicherheitsentscheidungen auf Instanzen der NIMBLE Plattform. Zusätzlich zu den Kernsicherheitsmechanismen in NIMBLE werden fortgeschrittene Techniken für das strategische Management von Netzwerkressourcen eingesetzt.

Abstract:

This paper presents an approach for optimal cyber security decisions to protect instances of a federated Internet of Things (IoT) platform in the cloud. The presented solution implements the repeated Stackelberg Security Game (SSG) and a model called Stochastic Human behaviour model with AttRactiveness and Probability weighting (SHARP). SHARP employs the Subjective Utility Quantal Response (SUQR) for formulating a subjective utility function, which is based on the evaluations of alternative solutions during decision-making. We augment the repeated SSG (including SHARP and SUQR) with a reinforced learning algorithm called Naïve Q-Learning. Naïve Q- Learning belongs to the category of active and model-free Machine Learning (ML) techniques in which the agent (either the defender or the attacker) attempts to find an optimal security solution. In this way, we combine GT and ML algorithms for discovering optimal cyber security policies. The proposed security optimization components will be validated in a collaborative cloud platform that is based on the Industrial Internet Reference Architecture (IIRA) and its recently published security model.
