Given the increasing cooperation between organizations, the flexible exchange of security information across the allied organizations is critical to effectively manage Information Systems (IS) security in a distributed environment. In this paper, the authors develop a cooperative model for IS security risk management in a distributed environment. In the proposed model, the exchange of security information among the interconnected IS under distributed environment is supported by Bayesian Networks (BNs). In addition, for an organization's IS, a BN is utilized to represent its security environment and dynamically predict its security risk level, by which the security manager can select an optimal action to safeguard the firm's information resources.
