After a series of introductionary remarks to the conference (there are multiple conferences here of which IEEE Social Computing is one), now there is a keynote speech by Stephen Lau on Privacy, Security, Risk and Trust in Service-Oriented Environments. Alex Pentland of MIT introduced the IEEE Social Computing conference of which my paper is part of the SIN workshop (Social Intelligence and Networking). If you're in the conference, then please talk to me, I will give a talk in SIN at the last session on Monday called "Finding Cohesive Subgroups and Relevant Members in the Nokia Friend View Mobile Social Network".
Dr. Lau is talking about information assurance in Service-Oriented Environments. Now, we are entering service-oriented computing. This is nothing new, IBM Research has advocated service-oriented computing for many years, and in academia and research, service-oriented computing is very important. However, there are challenges in service-oriented computing environments, like for example system reliability, must be easy to use, privacy, trust and tracking users. There are XML-based policies to help with this and software engineering is being used to tackle this.
So, what is Dr. Lau's research to address these issues? They have developed a framework for systematically managing and enforcing security policies and a model for flexible security policies. He just showed the workflow of the architecture of their framework. The complicated part of this research is the integrated framework for managing and evaluating security, privacy, trust and risk. We need to have new models for trust and risk considering technical, human and social aspects.
