The iNetSec conference papers collected in this book focus on the discussion of open research problems. In other words, instead of discussing security holes and vulnerabilities in existing technologies, the papers presented here cover problems that are a few years away. As expected, most of them are propositions that require a shift in the current technology paradigm discussed in each paper.

This conference, first held in April 2009, tries to cover topics that are not usually seen at traditional conferences. Although the most recent event was held in March 2010, this review focuses on the papers selected in 2009. However, the contents of these papers are still very relevant.

The 14 papers are divided into six sections. The first section, about involving humans, covers the flaws in current biometric security systems and problems with identifying humans from computers on the Web. Section 2, on Web 2.0, contains a topic that is heavily discussed nowadays: leveraging social links for trust and privacy. The third section is about protecting resources. It covers challenges and open problems in mitigating drive-by download attacks, and includes a proposal for context-dependent authentication and access control. Section 4, about pervasive devices, includes new directions in radio frequency identification (RFID) security and tailored security, and safety for pervasive computing. The next section is on protocol security, including peer-to-peer (P2P)-based voice and video streaming applications, rational protocols, and authorization for re-sharing. The final section is on privacy. Topics covered include privacy policies, tools and mechanism of the future, security and privacy preservation in human-involved networks, and metrics for anonymous networks.

This conference provides a thought-provoking international platform for intellectuals interested in the network security problems of tomorrow.
