This book presents the latest research in network and system security from the 7th International Conference on Network and System Security. The proceedings compile 41 full papers, 7 short papers, and 13 industrial track papers, all rigorously reviewed from 176 submissions. The papers are organized into topical sections covering network security, including modeling, evaluation, security protocols, and defense against network attacks, as well as system security, encompassing malware, intrusion detection, application security, cryptographic algorithms, privacy, and key distribution.

This volume represents a snapshot of the state of network and system security research as presented at the 2013 International Conference on Network and System Security. The breadth of topics covered, from fundamental cryptographic algorithms to practical applications and defense mechanisms, suggests a comprehensive overview for researchers and practitioners in the field. The inclusion of both full and short papers, alongside industrial track contributions, indicates a diverse range of perspectives and research maturity levels within the presented work.
