ACM International Workshop on Security in Software Defined Networks & Network Function Virtualization, New Orleans, LA, USA, March 11, 2016 (Submission Due December 1, 2015) Software-Defined Networking (SDN) and Network Function Virtualization (NFV) are two emerging networking paradigms, which introduce significant granularity, visibility, flexibility and elasticity to networking, but at the same time bring forth new security challenges. The ACM International Workshop on Security in Software Defined Networks & Network Function Virtualization (SDN-NFV Security 2016) will take place in New Orleans, LA, USA, on March 11, 2016. The target audience will be university researchers, scientists, and industry professionals who need to become acquainted with new theories and technologies related to security challenges in SDN and NFV. We solicit unpublished research papers, both regular (6 pages max) and short (4 pages max) papers, that address the latest practices, experiences, and lessons learned on SDN and NFV security. Topics of interest include, but are not limited to: - SDN/NFV-enabled security architecture - SDN/NFV-based automated network security - SDN/NFV-based mitigation for attacks - Authentication/confidentiality in SDN/NFV-based networks - Proofs of security in SDN/NFV-based networks - Logic flaws in SDN/NFV implementations - Attacks/defense to SDN controllers, protocols, and APIs - SDN-oriented security policy enforcement - Trust management of SDN applications and controllers - Development and deployment of NFV-based security functions (virtual firewalls, virtual IDSs, virtual DDoS mitigation, etc.) - Safe state migration in NFV - Network Security as a Service For more information, please see: http://honeynet.asu.edu/sdnnfvsec2016/
