Cyber Incident Classification 45 are critical to developing, managing and sustaining cyber incident classification systems. This short study demonstrates that OSCE participating States are affording greater attention to cyber incident classification within their broader incident and crisis management efforts. The report provides valuable insights into existing and emerging practices in the OSCE region in this regard. The aim of documenting these insights and practices is to use the knowledge derived from experiences of participating States to promote the use of incident classification systems nationally and regionally as a means to advance crisis management procedures and address challenges to national and transborder ICT networks, in the spirit of CBMs 15 and 3.
