DESCRIPTION:This study aims to understand efficient network fo
 rmation and optimal defensive resource distributio
 n in the presence of an intelligent attacker. We p
 resent a two-player dynamic framework in which the
  Defender and the Attacker compete in a network fo
 rmation and defence game with heterogeneous vertic
 es' values. Such a model allows for studying the t
 rade-off between network efficiency and security. 
 Contrary to the literature\, we find that a centra
 lly protected star network does not yield the maxi
 mum payoff for the defending side in most circumst
 ances\, even being the most secure network formati
 on. Additionally\, it reveals the new type of netw
 ork that often arises in an equilibrium of the gam
 es with limited defensive resources -- a maxi-core
  network.
