Research of Global Strategic Cyberspace Security Risk Evaluation System Based on Knowledge Service

In recent years, cyberspace has been formed and is continuously developing. It has fundamentally revolutionized the mechanism by which information is disseminated and utilized, in order to be closely involved in the physical world and human activities. However, from global perspective, factors such as the continuously increasing complexity of structure and function of cyberspace, the rising benefits from both economic and political aspects, the exposing of inherent vulnerabilities have all contributed to even severe security threats and risks targeting cyberspace, which have become a key factor in national security in the challenging situations. Strategic cyberspace risks are different kinds of core, structural and systematic risk that if were neglected to prevent and control, significant damage to cyberspace will be dealt and cause great economic loss. Aiming at exploring new ways and tackling with such strategic threats, the concept, elements and relationship between tactical and strategic risk in cyberspace was studied. A knowledge-based cyberspace strategic risk warning and assessment system with four data-driven layers was built, and two scenarios of heartbleed and Teamviewer vulnerability event are investigated to suggest possible use cases for our system.
