The Organization for Security and Co-operation in Europe has published a Good Practices Guide on Non-Nuclear Critical Energy Infrastructure Protection (NNCEIP) from Terrorist Attacks Focusing on Threats Emanating from Cyberspace. The Guide was developed by a number of public and private sector experts from OSCE participating States, as well as experts from the European Union (EU) and the North Atlantic Treaty Organization (NATO). Protecting the energy control systems that monitor, manage and control increasingly interconnected critical energy infrastructure from terrorist attacks is particularly relevant for the OSCE, whose 57 participating States and 11 Partners for Co-operation include some of the largest producers and consumers of energy, as well as many strategic transit countries. The importance of energy infrastructure and securing critical energy infrastructure cannot be overstated. Because critical energy infrastructure produces and distributes the fuel that keeps the global economy moving, it can be an attractive target for terrorists. While there are a number of threats to non-nuclear critical energy infrastructure, the Guide focuses on raising awareness of the significance of non-nuclear critical energy infrastructure and the extent to which it is threatened by cyber-related terrorist attacks, with some discussion of other types of potential threats. It explores key policy issues and challenges related to these threats and presents good practices for government policy-makers as well as private-sector owners and operators. The Guide catalogues policies, practices and institutional arrangements to enhance non-nuclear critical energy infrastructure cybersecurity, and illustrates the growing trend toward a co-operative, integrated (all hazards) and risk-based approach. It also demonstrates the growing interest in greater national and international co-operation and information exchange between public agencies and often private owners and operators of this essential infrastructure to help address the threat of cyber-related attacks. The project was sponsored by the United States, and the work on the Guide was coordinated by the Action against Terrorism Unit (ATU) of the Transnational Threats Department in the OSCE Secretariat. A Russian version is forthcoming.
