Attack and Defence as a Contest

In this talk we propose to model attack-defence computer related initiatives as a Tullock (1980) contest. This implies that players are seen to compete for some prize by investing resources, which will shape the success probability of an attack. Interestingly, in the simple two player framework we consider, at a Nash Equilibrium both players invest the same amount of resources, whether in a static or in a dynamic game. This represents a benchmark for extending the model and gain further insights on more general strategic frameworks.
