Welcome to the First workshop on Security, Trust and Privacy in Grid Environments (STPC 2008)

 

This workshop provides a forum to discuss and exchange research results regarding security, trust and privacy issues in distributed collaborative Grid environments. Grid computing enables large-scale sharing of widely distributed resources and coordinated collaboration for problem-solving between groups of partners (scientific or commercial community). Heterogeneous resources geographically distributed belong to different security domains with different access control and security policies to access them. Researchers and developers are concerned with possible security issues and implication of wide-spread collaboration because it is conducted on the basis of interactions and information exchange between heterogeneous environments with different security issues.

With Grid technologies playing an increasingly important role in new distributed computing deployments, there are increasing risks that the privacy and integrity of users’ information might be compromised. Then, trust and privacy becomes a fundamental issue; since information exchange in the form of interactions between heterogeneous environments is handled on behalf of the owners, these owners should know:
• who holds their sensitive information,
• who can access it and for what purpose and,
• how this information is handled (in order to avoid unauthorized changes or unauthorized transfers) via the Grid infrastructure middleware.
In light of these developments, a thorough analysis of threats to security, trust and privacy in Grid environments and their causes will be reviewed. Issues with respect to the degree of privacy loss, the release of constraints in terms of protection, and how they might be assessed will be addressed. The workshop also examines and compares new and different approaches, along with their technical solutions and practical designs in Grids. In addition, the workshop will attempt to examine the degree to which legal and organizational compliance for privacy in Grid can or should be achieved.
The workshop invites submissions from academia and industry presenting novel research on all theoretical and practical aspects of security, trust and privacy issues related to Grid environments. We encourage submissions from other communities such as law and business to present their perspectives on technological issues.

  • Topics of interest

The main topics of interest include but are not limited to:

Privacy and Security for Federated Distributed Environments Trust-Based Models and Usage-Based Models for Access Control in Grids

Invited Talk

Title: Modular Authorisation for Grids

Speaker: David W. Chadwick, Information Systems Security, Computing Laboratory, University of Kent, Canterbury, UK. link to presentation

Abstract:
This talk will describe the different functional components that go together to provide an authorization infrastructure for Grids. These include: Policy Enforcement Points, Policy Information Points, Policy Decision Points, Obligations Services, Credential Validation Services and Credential Issuing Services (or Attribute Authorities). By defining clean interfaces between these functional components, they may be connected together in various configurations to provide both the push and pull models for credential validation, with consequently differing amounts of work for the application to perform, and differing security properties (such as least or maximal privileges). Different credential formats can be supported as well as different protocols for interconnecting the components together. The talk will introduce the OGF OGSA Authz protocol profiles that are currently being specified to allow the components to be distributed around the grid, and the results of some early interworking tests that have been performed between different research groups.
Having a modular authorization infrastructure, such as the one being proposed here, allows the plug and play of similar functional components from different suppliers, that may contain appreciably different features e.g. enhanced performance, different credential formats, different policy rules, etc. It also leads to other benefits, such as the inclusion of significantly enhanced functional components that use the same interfaces, but contain additional authorization features, such as coordinated decision making or delegation of authority, without affecting either the grid applications or the other components of the authorization infrastructure.
