This paper examines information warfare between attackers, who try to gain access to information systems, or "targets", and defenders protecting those targets. we develop a game theoretic model in which both defenders and attackers act strategically and their actions are interdependent. our analysis focuses on the role of the information flows and shows that, ceteris paribus, rational attackers spend more effort on less protected targets. as a result, the defenders' security measures are more effective when attackers are informed about the targets' characteristics. Correctly anticipating future attackers' responses, targets with better levels of protection have stronger incentives to signal their security characteristics than poorly protected targets. Overall, defenders' ability to signal their security characteristics improves their welfare. our results have important implications for security practices and policies.
