Head of publishing: Jaanika Rannu Layout: Jaakko Matsalu NATO COOPERATIVE CYBER DEFENCE CENTRE OF EXCELLENCE The NATO Cooperative Cyber Defence Centre of Excellence (CCD COE) is a NATO- accredited knowledge hub in Tallinn, Estonia, offering a unique interdisciplinary approach to the most relevant issues in cyber defence. We conduct research, trainings and exercises in four core areas: technology, strategy, operations and law. The heart of the Centre is a diverse group of international experts from military, government, academia and industry, representing currently 21 member nations. Almost half as many nations are aspiring to become member in the years to come. NATO CCD COE’s mission is to support its member nations and NATO in the fields of cyber defence research, training and exercises. The Centre provides cyber defence expertise in the fields of technology, strategy, operations and law, often in an interdisciplinary manner. NATO CCD COE embodies and fosters the cooperation of like-minded nations in cyber defence. Our member nations are allies in NATO and like-minded partners beyond the Alliance. Research Areas Among other research areas, NATO CCD COE experts are currently involved in the analysis of autonomous features of cyber operations, digital forensics, protection of critical infrastructure, Cyber Command and Control, cyber deterrence, cyber effects in battlefield and attribution. NATO CCD COE is home of the Tallinn Manual 2.0, the most comprehensive guide for policy advisors and legal experts on how International Law applies to cyber operations carried out between and against states and state actors. An invaluable analysis by an international group of renowned scholars published in 2017, continues to inspire both academic research and state practice. Most of the Centre’s publications and research papers are available online on the Centre’s website www.ccdcoe.org, similarly to a database of national cyber security strategies, the International Cyber Developments Review and comprehensive overviews of national cyber security organizations. Education and Training NATO CCD COE promotes lifelong learning in cyber security. Our training courses are based on our latest research and cyber defence exercises. To best meet the training requirements of our Allies, Partners and NATO as a whole, we provide courses in different formats and locations, covering a broad range of topics in the technical, legal, strategic and operational cyber security domains. NATO CCD COE is responsible for identifying and coordinating education and training solutions in cyber defence for all NATO bodies across the Alliance. NATO Allied Command Transformation has provided NATO CCD COE with an unconditional quality assurance accreditation for its contribution to high-quality NATO Education and Training.

CyCon 2019 is the 11th iteration of the conference, organised by the NATO Cooperative Cyber Defence Centre of Excellence (NATO CCD COE) and taking place in Tallinn from 28 to 31 May 2019. Since 2009, CyCon has become a landmark conference addressing cyber conflict and security from the perspectives of technology, strategy, operations, law and policy. It brings together a trusted circle of decision- makers and experts representing government, the military, academia and the private sector. With the launch of the annual CyCon US conference series in cooperation with the US Army Cyber Institute in 2016, CyCon also serves as a transatlantic forum for the community of interest to discuss the most pressing issues of the cyber domain twice a year. The debates and presentations at CyCon stem both from original research papers submitted by the academic community and from insights offered by renowned experts in the field. The core topic of CyCon 2019 is ‘Silent Battle’. The topic is broad enough to allow for diverse interpretations: a techie will think in terms of vulnerabilities, exploits and patches; a policy advisor could approach it as detection and attribution; a lawyer may interpret it through the lens of responsibility; and the military may approach it in terms of situational awareness.
