Abstract:
In service computing, a system is built by integrating the services of many service providers. The security of each individual service affects the security of the system. This paper investigated the issues relating to security requirements of an integrated system using a game theoretical approach. It modeled three classes of service computing applications as three security games. Service providers and system owners can use the games to analyse the relationship between the level of security of the services and the security investment on a system. As a result, they can be more objective in their service level agreement negotiation.
