File and Memory Security Analysis for Grid Systems

The grid security architecture today does not prevent certain unauthorized access to the files associated with a job executing on a remote machine. Programs and data are transferred to a remote machine for completing staging jobs. Footprints may remain on the machine after the programs and data are deleted from the remote machine. Anyone with super user privileges can access these footprints. In this paper, we explore the problem of unauthorized access to programs and data, supporting it with experiments carried out using the Globus toolkit. After showing that programs and data are at risk, we also discuss ways for secure deletion of data and programs on the remote machine.
