Proceedings of the First ACM Workshop on Cyber-Physical Systems-Security and/or PrivaCy, CPS-SPC 2015, Denver, Colorado, USA, October 16, 2015

It is our great pleasure to welcome you to the Second ACM Workshop on Cyber-Physical Systems Security and PrivaCy (CPS-SPC) in conjunction with the 23rd ACM Conference on Computer and Communications Security (CCS) in Vienna, Austria. Our increased dependency on cyber-physical systems (CPS) has amplified concerns of cyber attacks on these systems. These transformative attack methods require additional research into secure control systems and related architectures of CPS. The majority of the published literature addressing the security and privacy of CPS reflect a field still in its infancy; as such, the overall principles, models, and theories for securing CPS have not yet emerged. It is hoped that this workshop will provide a focal point for the research community to begin addressing the security and privacy of CPS in a comprehensive and multidisciplinary manner and, in tandem with other efforts, build a comprehensive research roadmap. As a workshop, we expect to attract papers that reflect ongoing work that are still "works in progress". This year's workshop builds on the foundation laid last year to become one of the premier forums for presentation of interdisciplinary research results and experience reports at the interface of control theory, information security, embedded and real-time systems and human factors applied to CPS. The mission of the workshop is to create a community of researchers focusing on diverse aspects of CPS Security and Privacy, and to provide researchers and practitioners a premiere forum to share their perspectives with others interested in interdisciplinary approaches to solve the challenging security and privacy problems in CPS. The workshop attracted 26 submissions from across 10 countries, and all papers were reviewed by at least three program committee members. 12 papers were accepted leading to a 46% acceptance rate.
