Interdependent defense games with applications to Internet security at the level of autonomous systems
Chan, Hau; Ceyko, Michael; Ortiz, Luis - In: Games 8 (2017) 1, pp. 1-60
instances of IDD games based on the real-world Internet-derived graph at the level of autonomous systems (≈27 K nodes and ≈100 K … edges as measured in March 2010 by the DIMES project). We call such games Internet games. We introduce and empirically …-generated instances of Internet games. In general, preliminary experiments applying our proposed heuristics are promising. Our experiments …

Security investment, hacking, and information sharing between firms and between hackers
Hausken, Kjell - In: Games 8 (2017) 2, pp. 1-23
A four period game between two firms and two hackers is analyzed. The firms first defend and the hackers thereafter attack and share information. Each hacker seeks financial gain, beneficial information exchange, and reputation gain. The two hackers’ attacks and the firms’ defenses are...

Dynamic awareness and strategic adaptation in cybersecurity : a game-theory approach
Kostelić, Katarina - In: Games 15 (2024) 2, pp. 1-28
Awareness and human factors are becoming ever more important in cybersecurity, particularly in the context of small companies that may need more resources to deal with cybersecurity effectively. This paper introduces a theoretical framework for game analysis of the role of awareness in strategic...

A two-period game theoretic model of zero-day attacks with stockpiling
Wang, Guizhou; Welburn, Jonathan William; Hausken, Kjell - In: Games 11 (2020) 4/64, pp. 1-26
In a two-period game, Player 1 produces zero-day exploits for immediate deployment or stockpiles for future deployment. In Period 2, Player 1 produces zero-day exploits for immediate deployment, supplemented by stockpiled zero-day exploits from Period 1. Player 2 defends in both periods. The...

(Un)bounded rationality in decision making and game theory : back to square one?
Güth, Werner; Kliemt, Hartmut - In: Games 1 (2010) 1, pp. 53-65
Game and decision theory start from rather strong premises. Preferences, represented by utilities, beliefs represented by probabilities, common knowledge and symmetric rationality as background assumptions are treated as “given.” A richer language enabling us to capture the process leading...

A modal logic of epistemic games
Lorini, Emiliano; Schwarzentruber, François - In: Games 1 (2010) 4, pp. 478-526
We propose some variants of a multi-modal of joint action, preference and knowledge that support reasoning about epistemic games in strategic form. The first part of the paper deals with games with complete information. We first provide syntactic proofs of some well-known theorems in the area of...

Computer solution to the game of pure strategy
Rhoads, Glenn C.; Bartholdi, Laurent - In: Games 3 (2012) 3, pp. 150-156
We numerically solve the classical "Game of Pure Strategy" using linear programming. We notice an intricate even-odd behaviour in the results of our computations that seems to encourage odd or maximal bids.

The dynamics of costly signaling
Wagner, Elliott O. - In: Games 4 (2013) 2, pp. 163-181
Costly signaling is a mechanism through which the honesty of signals can be secured in equilibrium, even in interactions where communicators have conflicting interests. This paper explores the dynamics of one such signaling game: Spence’s model of education. It is found that separating...

External pressure on alliances : what does the prisoners’ dilemma reveal?
Binner, Jane M.; Fletcher, Leslie R.; Kolokoltsov, Vassili - In: Games 4 (2013) 4, pp. 754-775
Prompted by a real-life observation in the UK retail market, a two-player Prisoners’ Dilemma model of an alliance between two firms is adapted to include the response of a rival firm, resulting in a version of a three-player Prisoners’ Dilemma. We use this to analyse the impact on the...
