Tracking the security enforcement in a grid system

The "Grid Security Monitor" tracks the security status of resources in a grid computer system. When a client submits a job to the grid scheduler, the Grid Security Monitor creates a security contract. The security contract comprises all the security credentials needed to access the resource executing the job, as well as privacy and security requirements. The Grid Security Monitor compares the security status of the resource to the requirements of the security contract. If the security status of the resource changes or violates the security contract, then the Grid Security Monitor notifies the client. The Grid Security Monitor has a user interface that allows the client to perform a manual security validation by asking the grid management system to verify the security status of the resource.
