The paper reviews the security problem with computing and information resources in Grid systems. It discusses security relative characteristics of Grid architecture and provides a common threat model of Grid. It summarizes methods being applied to improve security of Grid systems and discusses their disadvantages. There is proposed the Petri-net-based model of access control for Grid systems. That model enhances Grid security with trusted ’job’ submission (in strict accordance with security policy constraints) and verification of the security implementation in Grid systems.
