摘要: Security is one of the main concerns in current telecommunication networks: service providers and individual users have to protect themselves against attacks, this end a careful analysis their optimal strategies essential importance. Indeed, attackers defenders are typically agents trying strategically design most important damages secure use resources, respectively, natural modelling framework these interactions that noncooperative game theory. This chapter aims at providing comprehensive review game-theoretic aspects security. We first describe basics on theory through simple security problems, then present discuss some specific problems more detail. Finally, we also deal with economics, focusing selfish relationships between customers as well competing providers, which represents another aspect our non-standard approach towards risk assessement.
