CFP as PDF The proliferation of commercial activities over different networked systems has brought security concerns on an unprecedented scale. From traditional Internet-based applications to newly emerging ubiquitous services over 3G, Wireless LAN, and mobile ad hoc and sensor networks, there is an increasing demand of measures to guarantee the confidentiality, integrity, and availability of system services. The main purpose of this workshop is to promote further research interests and activities on network security. It is also aimed at increasing the synergy between academic and industrial researchers working in this area. We are interested in experimental, systems-related, and work-in-progress papers in all aspects of network security. The topics of interest include (but are not limited to): Novel and emerging secure architecture Study of attack strategies, attack modeling Case studies and analysis of actual attacks Continuity of Operations during an attack Key management Trust management Intrusion detection techniques Intrusion response, alarm management, and correlation analysis Study of tradeoffs between security and system performance Intrusion tolerance systems Secure protocols Security in wireless networks (e.g., ad hoc networks, sensor networks, WiMAX, WPAN, etc.) Case studies and analysis of actual attacks Continuity of Operations during an attack
