Social networks where people exchange personal and public information
have enabled users to connect with their friends, coworkers,
colleagues, family and even with strangers.  Several social networking
sites have developed to facilitate such social interactions and
sharing activities on the Internet over the past several years. The
popularity of social networking sites on the Internet introduces the
use of mediatedÐcommunication into the relationship development
Also, online social networks have recently emerged as a promising area
of research with a vast reach and application space. Users post
information on their profiles to share and interact with their other
friends in the social network. Social networks are not limited to
simple entertaining applications; instead several critical businesses
have adopted social networks to attract new customer spaces and to
provide new services. The current trends of social networks are
indirectly requiring users to become system and policy administrators
for protecting their content in this social setting. This is further
complicated by the rapid growth rate of social networks and by the
continuous adoption of new services on social networks. Furthermore,
the use of personal information in social networks raises entirely new
privacy concerns and requires new insights on security problems.
Several studies and recent news have highlighted the increasing risk
of misuse of personal data processed by online social networking
applications and the lack of awareness among the user population. The
security needs of social networks are still not well understood and
are not fully defined. Nevertheless it is clear these will be quite
different from classic security requirements. It is important to bring
a depth of security experience from multiple security domains and
technologies to this field as well as depth and breadth of knowledge
about social networks.
The aim of this special issue is to encompass research advances in all
areas of security and privacy in social networks. We welcome
contributions relating to novel technologies and methodologies for
securely building and managing social networks and relevant secure
applications as well as to cross-cutting issues.
Topics of interest: include but are not limited to
- Access control and identity management
- Delegation and secure collaboration 
- Information flow, diffusion and auditing
- Malware analysis in social networks
- Privacy challenges and mechanism
- Risk assessment and management
- Secure social-network application development and methodologies
- Secure object tagging, bookmarking and annotations
- Trust and reputation management
- Usability driven security mechanisms
