Plenary Panel 2: Collaborative Computing vs. Security and Privacy

Tuesday, October 12, 2010, 8:30 – 10:00

Moderator: James Joshi, University of Pittsburgh, USA

  • Mohamed Eltoweissy, Pacific Northwest National Laboratory, and Virginia Tech, USA
  • John Zic, CSIRO, Australia
  • Murat Kantarcioglu, University of Texas at Dallas, USA

Panel Statement

Recent developments in ITC have generated a tremendous potential for global-level collaborations and coordination among humans, organizations and nations to achieve various social and economic goals. The growing integration of physical and cyber domains is pushing such collaboration to an unprecedented level. Collaborative computing paradigms aim to further make such collaboration and coordination more efficient and seamless. Emerging distributed computing environments such as, Web 2.0, Social Networks, Cyber-physical systems, Cloud Computing, Human-centric/Social computing etc., represent some recent developments in collaborative computing. At the same time, our growing dependence on such collaborative computing environments and the newly-emerging challenges in protecting huge amounts of information that such infrastructures have to store, process and share have generated huge concerns related to their deployment. Compromise of security and privacy aspects of such systems now also have a potential to inflict unimaginable level of socioeconomic damage to humans, organizations and societies as such environments can typically be deemed as secure as the weakest component. Hence, the goal of facilitating collaborations and achieving security and privacy can appear as being at odds with each other. This panel will focus on discussing security/privacy issues against the goals of collaborative computing to streamline efficient collaboration across the hardware, software, and user/organization levels. In particular, the panel will focus on answering the following key questions:
  • Is Collaborative computing fundamentally in conflict with Security and privacy goals? The panelists will present their views regarding how collaboration makes it difficult to achieve security/privacy and how enforcing security/privacy severely reduces the ability to collaborate.
  • What holistic approaches/paradigms exist or are needed towards ensuring that we significantly enhance the balance between the need for collaboration and the need for security/privacy?
The panelists will discuss their views regarding what approaches and paradigms are crucial to address the growing challenges in collaboration and security/privacy more effectively and what paradigm shift is needed, if any. In particular, the panel will motivate the need for both evolutionary progress as well as revolutionary developments that may be needed to address the collaboration vs security issues.
