While cybersecurity has traditionally been a technological discipline, the field has grown so large and complex that proper governance of cybersecurity is needed.The primary audience for this book is advanced level students in computer science focusing on cybersecurity and cyber risk governance.

This is the first comprehensive treatment of subjective logic and all its operations. The author developed the approach, and in this book he first explains subjective opinions, opinion representation, and decision-making under vagueness and uncertainty, and he then offers a full definition of subjective logic, harmonising the key notations and formalisms, concluding with chapters on trust networks and subjective Bayesian networks, which when combined form general subjective networks. The author shows how real-world situations can be realistically modelled with regard to how situations are perceived, with conclusions that more correctly reflect the ignorance and uncertainties that result from partially uncertain input arguments. The book will help researchers and practitioners to advance, improve and apply subjective logic to build powerful artificial reasoning models and tools for solving real-world problems. A good grounding in discrete mathematics is a prerequisite.

The NordSec workshops were started in 1996 with the aim of bringing together - searchers and practitioners within computer security in the Nordic countries – thereby establishing a forum for discussions and co-operation between universities, industry and computer societies. Since then, the workshop has developed into a fully fledged inter- tional information security conference, held in the Nordic countries on a round robin basis. The 14th Nordic Conference on Secure IT Systems was held in Oslo on 14-16 October 2009. Under the theme Identity and Privacy in the Internet Age, this year's conference explored policies, strategies and technologies for protecting identities and the growing flow of personal information passing through the Internet and mobile n- works under an increasingly serious threat picture. Among the contemporary security issues discussed were security services modeling, Petri nets, attack graphs, electronic voting schemes, anonymous payment schemes, mobile ID-protocols, SIM cards, n- work embedded systems, trust, wireless sensor networks, privacy, privacy disclosure regulations, financial cryptography, PIN verification, temporal access control, random number generators, and some more. As a pre-cursor to the conference proper, the Nordic Security Day on Wednesday 14 October hosted talks by leading representatives from industry, academia and the g- ernment sector, and a press conference was given.

This book constitutes the refereed proceedings of the 17th Nordic Conference on Secure IT Systems, NordSec 2012, held in Karlskrona, Sweden, in October 2012. The 16 revised papers were carefully reviewed and selected from 32 submissions. The papers are organized in topical sections on application security, security management, system security, network security, and trust management.
